Bed-ly serious: A brief look at ‘sleeping addiction’
As a life-long insomniac, I’ve always been interest in sleep at a personal level. In 1984, when I was studying for my psychology degree, the first ever research seminar I attended was one on the psychology of sleep by Dr. Jim Horne (who was, and I think still is, at Loughborough University). I found the lecture really interesting and although I never pursued a career in sleep research it was at that point that I started to take an interest more professionally. In my blog I’ve written a number of articles on various aspects of sleep including sexsomnia (engaging in sexual acts while sleeping, for instance, while sleepwalking), somnophilia (engaging in sexual acts while individuals are sleeping), Sleeping Beauty paraphilia (a sub-type of somnophilia in which individuals are sexually aroused by watching other people sleep), and lucid dreaming (where individuals are aware they are dreaming and exert some kind of control over the content of the dream),
More recently, I’ve been a co-author on a number of research papers in journals such as Sleep Medicine Reviews, Journal of Sleep Research, and Sleep and Biological Rhythms (see ‘Further reading below) but these have all involved either the effects of internet addiction on sleep or the psychometric evaluation of insomnia screening instruments rather than being about the psychology of sleep.
In a previous A-Z article on “strange and bizarre addictions” I included ‘sleep addiction’ as one of the entries. Obviously I don’t believe that sleeping can be an addiction (at least not by my own criteria) but the term ‘sleep addiction’ is sometimes used to describe the behaviour of individuals who sleep too much. Conditions such as hypersomnia (the opposite of insomnia) has been referred to ‘sleeping addiction’ (in the populist literature at least). In a 2010 issue of the Rhode Island Medical Journal, Stanley Aronson wrote a short article entitled ‘Those esoteric, exoteric and fantabulous diagnoses’ and listed clinomania as the compulsion to stay in bed. Given the use of the word ‘compulsive’ in this definition, there is an argument to consider clinomania as an addiction or at least a behaviour with addictive type elements.

In an online article entitled ‘Sleep addiction’, Amber Merton also mentioned clinomania in relation to an addiction to sleep:
“If you are obsessed with sleeping or have an intense desire to stay in bed, you could be suffering from a condition called clinomania. That doesn’t mean that there aren’t people who can experience symptoms similar to addiction and even withdrawal in association with sleep, or lack thereof”.
The reference to ‘addiction-like’ symptoms appears to have some validity based on these self-report accounts I found online. All of these individuals mention various similarities between their constant need for sleep and addiction. I have highlighted these to emphasize my assertions that some of the consequences are at the very least addiction-like:
- Extract 1: “I believe someone can become psychologically dependent on sleep. I am 47 and have used sleep for 40 years to escape from life…I typically sleep 4-6 hours too much each day. Sleep feels like an addiction to me because I crave it several times a day and am looking forward to how I can sneak it in. I don’t seem to be able to control it with will power for very long…I only have short periods when this isn’t a problem. When I am under stress it is at its worse. If I have any free or unstructured time, I can’t control how much I sleep excessively. When my time is heavily scheduled, I really struggle with keeping a full schedule and crave the time off when I can sleep for hours. If I know I’ll have a few hours in between activities free, I will find ways to sneak in some sleep. I am embarrassed about this, don’t tell the people around me the extent of the problems and devise ways to sneak in sleep without people knowing”.
- Extract 2: “I love sleeping. It feels so good I think I could even become addicted if I didn’t HAVE to wake up. I sleep about 12 hours every day and could sleep more if I didn’t have to do daily necessities. I am aware of the fact that people who generally sleep more than they are supposed to, die sooner and have other various health problems. To be honest I would rather sleep than do most things. I even choose sleep over sex a lot”.
- Extract 3: “I often sleep for 12-20 hours at a time. I have depression and am on anti-depressants. I just love sleeping. It’s so safe and comfy. I don’t know how else to explain it. It’s just amazing”.
- Extract 4: “I sleep AT LEAST 12 hours a day. But on days off I’ve been known to sleep for about 15-20 hours. [I am] addicted to sleep. I’ve cancelled social outings with friends pretending to be sick when really I just wanted to sleep in. I love sleep and I can’t get enough of it. I’ve slept through the entire weekend multiple times before, only waking up Monday morning when my alarm rang. And even after that much wonderful sleep I was still tired. The second I come home from work every day I eat, shower, and then crawl into bed and sleep the entire evening and night away. My alarm’s the only thing that can wake me up anymore…As for why I love sleep so much, I see a lot of people saying it’s an escape for them. For me it’s more, I don’t like people or going out or socializing, so sleep is my drug of choice. Is it bad? Maybe. Do I care? Not really…I more than love it, and it’s not hurting anyone if we’re being honest”.
- Extract 5: “I feel like I’m addicted to sleep. Here’s why I think though. I suffered for 13 years with depression and while I know I am still getting over it I don’t feel that’s the reason I’m addicted. During those 13 years I would have serious bouts of chronic insomnia. The doctors tried to many different sleeping medications, meditation, clinics to help me find a routine for natural sleep without meds. Nothing worked. Now I live in Thailand and my doctor here recommended melatonin tablets, all natural as your brain is supposed to produce it anyway to tell you when it’s dark it’s time to sleep and when it’s like light it’s time to wake up. She thinks my brain fails to produce certain chemicals as such with serotonin and now figured melatonin. Since I have been taking a melatonin supplement, I sleep so well, I fall asleep within 20 minutes and I sleep for AT LEAST 8 hours. When I wake up I just want to go back to sleep again because it feels amazing. I don’t feel like it’s part of my anxiety or my depression, I just think it’s because I had insomnia for so long its addictive!”
- Extract 6: “To be honest if I could I would sleep my life away. My so called normal sleeping pattern: I am awake all night. Fall asleep around 4am-8am. Sleep 12 hours. Repeat. My mind is a broken record, constantly repeating the trauma. I do suffer from depression and anxiety. Sleep is my addiction. When I sleep I feel SAFE regardless?”
- Extract 7: “I’ve been addicted to sleep (the escape from an abusive childhood, depression, and PTSD) since I was ten years old! I want to change though because my body is a mess. I’ve slept for 4 days and sometimes more with short awake periods to eat a little and use the potty. Not enough though, because now my body doesn’t work properly…Oversleeping has its consequences”.
- Extract 8: “I’m so pleased that I have found this site and other people who are addicted to sleep as this problem has plagued my adult life and I would like it to stop. Take today for instance, I woke at 5.30am and was quite awake feeling a little anxious but I could not wait to get to sleep again, so I did and stayed in bed till around 2.20 pm. I have many days like this and as the lady above the sleep state is quite lucid and I do seem to enjoy it rather than getting up and living life for real”.
Again, I reiterate that none of these individuals are addicted to sleep but in addition to the addiction-like descriptions, there is also crossover in the motivations for excessive sleep and motivations underlying addictions (most noticeably the association with depression, anxiety, psychological trauma, and using the activity as an escape). In relation to addiction, these extracts include references to salience (engaging in sleep to the neglect of everything else in their life), cravings (for sleep), the sleep being excessive, repetitive and habitual, sleep leading to negative consequences (conflict), and loss of control. The fact that many of these individuals describe their behaviour as an addiction or addictive doesn’t mean that it is.
While there is no academic paper that I know of that has ever claimed sleep can be a genuine addiction there are countless clinical and empirical papers examining excessive sleep (i.e., hypersomnia) and the different etiological pathways that can lead to hypersomnia. Although hypersomnia is not an addiction, those with the condition (like addicts) can suffer many negative side-effects from the relatively minor (e.g., low energy, fatigue, headaches, loss of appetite, restlessness, hallucinations) to the more severe (e.g., diabetes, obesity, heart disease, clinical depression, memory loss, suicidal ideation, and in extreme cases, death). In one online article I came across, the similarity between hypersomnia and addiction in relation to depression was evident:
“It’s important to note that in some cases separating cause from effect here can be muddled. For instance, does over sleeping contribute to depression or does depression contribute to oversleeping? Or are both oversleeping and depression the effect of a larger underlying cause? Furthermore, once a person is experiencing both, could they act to reinforce the other as a feedback loop?”
This observation could just as easily be made about most addictions (substance or behavioural). Finally, it’s worth noting that there are many sub-types of hypersomnia and excessive sleep. In a good review of hypersomnia [HS] in Current Neurology and Neuroscience Reports, Dr. Yves Dauvilliers notes the following hypersomnia sub-types (including narcolepsy which can include excessive sleep but isn’t usually classed as a type of hypersomnia; also note that ‘idiopathic’ means of unknown cause) which I have paraphrased below:
- Narcolepsy: This is a disabling neurologic disorder characterized by excessive daytime sleep (EDS) and cataplexy (i.e., a sudden loss of voluntary muscular tone without any alteration of consciousness in relation with strong emotive reactions such as laughter, joking).
- Narcolepsy without cataplexy: This is simply a variant of narcolepsy with cataplexy (but without the cataplexy).
- Idiopathic hypersomnia: Idiopathic HS is rare and remains a relatively poorly defined condition due to the absence of specific symptoms such as cataplexy or sleep apneas (i.e., loss of breathing while sleeping).
- Recurrent hypersomnia: This HS is characterized by repeated episodes of excessive sleep (at least 16 hours a day) lasting from a few days up to several weeks. The most well-known recurrent HS is Kleine-Levin syndrome which comprises both cognitive disturbances (feelings of confusion and unreality) and behavioural disturbances (such as overeating and hypersexual behaviour during symptomatic episodes).
- Hypersomnia associated with neurologic disorders: This type of HS causes EDS and can be a result of brain tumours, dysfunction in the thalamus, hypothalamus, or brainstem that may mimic idiopathic HS or narcolepsy.
- Hypersomnia associated with infectious disorders: This type of HS can be a result of viral infection such as HIV pneumonia, Whipple’s disease (a systemic disease most likely caused by a gram-positive bacterium), or Guillain-Barré syndrome (a rapid-onset muscle weakness caused by the immune system damaging the peripheral nervous system).
- Hypersomnia associated with metabolic or endocrine disorders: This type of HS can be a result of conditions such as hyperthyroidism, diabetes, hepatic encephalopathy (a liver dysfunction among individuals with cirrhosis), and acromegaly (a hormonal disorder that develops when the pituitary gland produces too much growth hormone).
- Hypersomnia caused by drugs: This type of HS is secondary to many different types of drug medication including hypnotics, anxiolytics, antidepressants, neuroleptics, anti-histamines, and anti-epileptics.
- Hypersomnia not caused by drugs or known physiologic conditions: This type of HS can be caused by a range of disorders such as depressive disorder, seasonal affective disorder, and abnormal personality traits.
None of these types of HS is an addiction but clearly the negative consequences can be just as serious for the individual.

Needers of the pack: A brief look at addiction to Solitaire
A few days ago I was interviewed by Business Insider about the addictiveness of the card game Solitaire (also known as Klondike and Patience). The ‘hook’ for the Business Insider article (no pun intended) was that May 22 is National Solitaire Day (NSD). A quick look on the online National Day Calendar confirmed that NSD does indeed exist (a celebration day that only began for the first time last year) and the website also pointed out that the game is over 200 years’ old and that Solitaire “truly went viral” in 1990 when Microsoft included the Microsoft Solitaire game in Windows 3.0 (as a way to teach people how to use the mouse on their computers). The NSD webpage notes that:
“Over the past 28 years, Microsoft Solitaire has been providing great entertainment to hundreds of millions of players in every corner of the world…In 2012, Microsoft evolved Solitaire into the Microsoft Solitaire Collection, which features five of the top Solitaire games in one app. Since then, the game has been played by over 242 million people and has become so popular that each year 33 billion games are played with over 3.2 trillion cards dealt!”
Back in 2000, a short article on internet addiction in The Lancet by Peter Mitchell noted that one of the pioneers in internet addiction research, the clinical psychologist Maressa Hecht Orzack claimed to have a problem (a “near addiction”) playing Solitaire. Orzack was quoted in Mitchell’s article as saying: “So now I don’t have a computer at work. [My playing Solitaire] was getting that serious”. Orzack was also quoted in the Business Insider article. Her Solitaire playing was a “growing obsession” and she neglected her work and lost sleep because of her Solitaire playing. She said: “I kept playing solitaire more and more – my late husband would find me asleep at the computer. I was missing deadlines. I knew something had to be done”.
As far as I am aware, there is no empirical research about addiction to Solitaire, and I’ve never come across a published case study. However, I have mentioned Solitaire in a number of my papers over the years but all of them were in my critique of Dr. Kimberley Young’s taxonomy of the different types of internet addiction. Young claimed there were five different types of internet addiction (‘cyber-sexual addiction’, cyber-relationship addiction, ‘net compulsions’, ‘information overload’ and ‘computer addiction’). In a number of my publications in journals such as the Student British Medical Journal (1999), Addiction Research (2000), and the International Journal of Mental Health and Addiction (2006), I argued that the typology was flawed and that most of the examples Young provided were addictions on the internet, not addictions to the internet (and echoing my assertion that individuals are no more addicted to the internet than alcoholics are addicted to bottles).
The reference to Solitaire was in relation to Young’s final type of internet addiction – ‘computer addiction’. One of her examples of ‘computer addiction’ as the playing of Solitaire on computers. (I found this strange particularly because the example didn’t even rely on being on the internet – it was merely about individuals being addicted to playing Solitaire on computers and laptops). Young never provided any empirical evidence that she had ever met or treated anyone with an addiction to Solitaire, just that being addicted to Solitaire would be classed as a ‘computer addiction’ in her typology.
Young is not the only social scientist to use Solitaire as an example in an addiction typology. In a 2008 paper published in the Journal of Applied Social Science, Jawad Fatayer outlined what he believes are the four types of addiction – alpha addictions (addictions that impact the body and physical health such as nicotine addiction and food addiction), beta addictions (addictions that impact the mind and the body such as alcohol and other drug addictions), gamma addictions (all behavioural addictions), and delta addictions (two or more addictions experiences simultaneously). Addiction to Solitaire was listed as a gamma addiction (but again, there was no empirical evidence to support the claim that Solitaire addiction actually exists).
Business Insider spoke to two other psychologists in addition to myself. Dr. Chris Ferguson (with whom I have co-authored a few papers) said:
“It’s important to recognize the difference between really liking something and having a clinical addiction. People (say) ‘I’m addicted to cupcakes’, ‘I’m addicted to chocolate’ meaning ‘This is a really fun thing that I like to do a lot’. There’s a huge debate that goes on in the field right now about whether video games can be compared to things like substance abuse, or if video games are more similar to hobby-like activities that many people enjoy — and some people might overdo…a fixation with Solitaire is more of a behavioral addiction – an obsessive behavioral pattern that can be a sign of underlying mental distress or illness. People who have mental health issues, or are simply under stress, tend to be drawn to things that are fun and distracting. And that’s mostly good, actually. It’s just that sometimes, for some individuals, they may begin to really overdo those activities as a form of escapism…It’s not about technology. It’s about mental health”.
A clinical psychologist, Anthony Bean said:
“There are some clear signs that Solitaire might be playing too big a role in your life. (If you’re) noticing you’re putting more time than other areas into the game and, let’s say, not paying attention to your family, not paying attention to work, not paying attention to school”.
My contribution to the Business Insider was taken from an email I sent the journalist. Very little of what I sent was used. I was asked two specific questions: (i) what characteristics of the game Solitaire might make it addicting? and (ii) what should people be aware of as signs of a disruptive addiction to Solitaire (or gaming in general)?
In answer to the first question, I wrote that addictions rely on constant rewards (what psychologists refer to as reinforcement) and each game of Solitaire can be played quickly and individuals can be quickly rewarded if they win (positive reinforcement) but when they lose, the feeling of disappointment or cognitive regret can be eliminated by playing again straight away (negative reinforcement – playing as way to relive a dysphoric mood state). I also stated that addictions typically result as a coping mechanism to other things in a person’s life. They use such behaviours as a way of escape and the repetitive playing of games can help in such circumstances. For the overwhelming majority of people, such playing behaviour will be an adaptive coping mechanism but if the game takes over all other aspects of the person’s life and compromises their relationships and their education/occupation (depending upon their age), this becomes a poor coping strategy because the short-term benefits are heavily outweighed by the long-term costs.
In relation to the second question, I outlined what I believe to be the six core criteria of addictive behaviour and outlined them with what I believed a genuine Solitaire addiction would constitute. My response was purely hypothetical because I have never met or even heard of anyone being genuinely addicted to Solitaire. So, hypothetically, Solitaire addiction would comprise anyone that fulfilled all of the following six criteria:
- Salience –This occurs when Solitaire becomes the single most important activity in the person’s life and dominates their thinking (preoccupations and cognitive distortions), feelings (cravings) and behaviour (deterioration of socialised behaviour). For instance, even if the person is not actually playing Solitaire they will be constantly thinking about the next time that they will be (i.e., a total preoccupation with Solitaire).
- Mood modification –This refers to the subjective experiences that people report as a consequence of playing Solitaire and can be seen as a coping strategy (i.e., they experience an arousing ‘buzz’ or a ‘high’ or paradoxically a tranquilizing feel of ‘escape’ or ‘numbing’).
- Tolerance –This is the process whereby increasing amounts of time spent playing Solitaire are required to achieve the former mood modifying effects. This basically means that for someone engaged in Solitaire, they gradually build up the amount of the time they spend playing Solitaire every day.
- Withdrawal symptoms– These are the unpleasant feeling states and/or physical effects (e.g., the shakes, moodiness, irritability, etc.), that occur when the person is unable to play Solitaire because they are ill, have no computer connection, etc.
- Conflict – This refers to the conflicts between the person and those around them (interpersonal conflict), conflicts with other activities (social life, hobbies and interests) or from within the individual themselves (intra-psychic conflict and/or subjective feelings of loss of control) that are concerned with spending too much time playing Solitaire
- Relapse– This is the tendency for repeated reversions to earlier patterns of excessive Solitaire playing to recur and for even the most extreme patterns typical at the height of excessive Solitaire playing to be quickly restored after periods of control.
Finally, I just want to reiterate that I know of no evidence to support the contention that there are individuals genuinely addicted to Solitaire. However, I do think it’s theoretically possible even though I’ve yet to meet or hear about such individuals.

More mass debating: Compulsive sexual behaviour and the internet
The issue of sex addiction as a behavioural addiction has been hotly debated over the last decade. A recent contribution to this debate is a review by Shane Kraus and his colleagues in the latest issue of the journal Addiction that examined the empirical evidence base for classifying compulsive sexual behaviour (CSB) as a behavioural (i.e., non-substance) addiction. The review raised many important issues and highlighted many of the problems in the area including the problems in defining CSB, and the lack of robust data from many different perspectives (epidemiological, longitudinal, neuropsychological, neurobiological, genetic, etc.).
As my regular blog readers will know, I have carried out empirical research into a wide variety of different behavioural addictions (gambling, video gaming, internet use, exercise, sex, work, etc.) and have argued that some types of problematic sexual behaviour can be classed as sex addiction depending upon the definition of addiction used. I was invited by the editors of Addiction to write a commentary on the review and this has just been published in the same issue as the paper by Kraus and colleagues. This blog briefly looks at the issues in that review that I highlighted in my commentary.
For instance, there are a number of areas in Kraus et al.’s paper that were briefly mentioned without any critical evaluation. For instance, in the short section on co-occurring psychopathology and CSB, reference was made to studies claiming that 4%-20% of those with CSB also display disordered gambling behaviour. I pointed out that a very comprehensive review that I published with Dr. Steve Sussman and Nadra Lisha (in the journal Evaluation and the Health Professions) examining 11 different potentially addictive behaviours also highlighted studies claiming that sex addiction could co-occur with exercise addiction (8%-12%), work addiction (28%-34%), and shopping addiction (5%-31%). While it is entirely possible for an individual to be addicted to (say) cocaine and sex concurrently (because both behaviours can be carried out simultaneously), there is little face validity that an individual could have two or more co-occurring behavioural addictions because genuine behavioural addictions consume large amounts of time every single day. My own view is that it is almost impossible for someone to be genuinely addicted to (for example) both work and sex (unless the person’s work was as an actor/actress in the pornographic film industry).
The paper by Kraus et al also made a number of references to “excessive/problematic sexual behavior” and appeared to make the assumption that ‘excessive’ behaviour is bad (i.e., problematic). While I agree that CSB is typically excessive, excessive sex in itself is not necessarily problematic. Preoccupation with any behaviour in relation to addiction obviously needs to take into account the context of the behaviour, as the context is far more important in defining addictive behaviour than the amount of the activity undertaken. As I have constantly argued, the fundamental difference between a healthy excessive enthusiasms and addictions is that healthy excessive enthusiasms add to life whereas addictions take away from them.
The paper also appeared to have an underlying assumption that empirical research from a neurobiological and genetic perspective should be treated more seriously than that from a psychological perspective. Whether problematic sexual behaviour is described as CSB, sex addiction and/or hypersexual disorder, there are thousands of psychological therapists around the world that treat such disorders. Consequently, clinical evidence from those that help and treat such individuals should be given greater credence by the psychiatric community.
Arguably the most important development in the field of CSB and sex addiction is how the internet is changing and facilitating CSB. This was not even mentioned until the concluding paragraph yet research into online sex addiction (while comprising a small empirical base) has existed since the late 1990s including sample sizes of up to almost 10,000 individuals. In fact, there have been a number of recent reviews of the empirical data concerning online sex addiction including its treatment including ones by myself in journals such as Addiction Research and Theory (in 2012) and Current Addiction Reports (in 2015). My review papers specifically outlined the many specific features of the Internet that may facilitate and stimulate addictive tendencies in relation to sexual behaviour (accessibility, affordability, anonymity, convenience, escape, disinhibition, etc.). The internet may also be facilitating behaviours that an individual would never imagine doing offline such as cybersexual stalking.
Finally, there is also the issue of why Internet Gaming Disorder was included in the DSM-5 (in Section 3 – ‘Emerging measures and models’) but sex addiction/hypersexual disorder was not, even though the empirical base for sex addiction is arguably on a par with IGD. One of the reasons might be that the term ‘sex addiction’ is often used (and arguably misused) by high profile celebrities as an excuse to justify their infidelity (e.g., Tiger Woods, Michael Douglas, David Duchovny, Russell Brand), and is little more than a ‘functional attribution’. For instance, the golfer Tiger Woods claimed an addiction to sex after his wife found out that he had many sexual relationships during their marriage. If his wife had never found out, I doubt whether Woods would have claimed he was addicted to sex. I would argue that many celebrities are in a position where they are bombarded with sexual advances from other individuals and have succumbed. But how many people would not do the same thing if they had the opportunity? Sex only becomes a problem (and is pathologised) when the person is found to have been unfaithful. Such examples arguably give sex addiction a ‘bad name’, and provides a good reason for those not wanting to include such behaviour in diagnostic psychiatry texts.
