Tales of the unexpected: 10 bad habits that sometimes do us good (Part 1)

All of us have bad habits, and all of us from time to time feel guilty about these habits. But there are some bad habits – at least when carried out in moderation – that might actually have benefits for psychological and/or physical wellbeing. Most bad habits help change our mood state and reduce stress (at least in the very short-term) but tend to become less helpful the more they are engaged in. Some of these bad habits turn into addictions where the short-term benefits are outweighed by the long-term costs. However, there are many activities that can sometimes have unexpected benefits and five of these are outlined in this blog. The next five bad habits will be in my next blog.

(1) Fidgeting helps burn calories

While fidgeting might be annoying for individuals and those around them, it is an activity that expends energy and burns calories. Fidgeting is one of a number of activities (along with walking, gardening, typing, tidying up, etc.) that are known as non-exercise activity thermogenesis (NEAT). In basic terms, NEAT is any activity that is not eating, sleeping, or sporting exercise. A number of studies carried out by obesity expert Dr. James Levine at the US Mayo Clinic (Arizona, US) have shown that individuals who fidget burn up about 350kcal a day. This is because fidgeting speeds up an individual’s metabolism by stimulating neurochemicals in the body thus increasing the ability to convert body fat into energy. So, if you are a compulsive foot tapper, an excessive thumb twiddler, or a restless doodler, just remember that all of these activities burn calories.

(2) Chewing gum helps boost thinking and alertness

Watching people chew gum is not a pretty site but if English football managers are anything to go by, chewing gum appears to be a stress relieving activity. In fact, there appear to appear to be many cognitive benefits of chewing gum. Dr. Kin-ya Kubo and colleagues in the book Senescence and Senescence-Related Disorders noted that chewing gum immediately before performing a cognitive task increases blood oxygen levels in the prefrontal cortex and hippocampus (important brain structures involved in learning and memory), thereby improving task performance. Dr. Kubo argues that chewing gum may therefore be a drug-free and simple method of helping those with senile dementia and stress-related disorders that are often associated with cognitive dysfunction. Another study by Dr. Yoshiyuki Hirano and colleagues showed that chewing gum boosts thinking and alertness, and that reaction times among chewers were 10% faster than non-chewers. The research team also reported that up to eight areas of the brain are affected by chewing (most notably the areas concerning attention and movement). As Professor Andy Smith (Cardiff University, UK) neatly summed up: “The effects of chewing on reaction time are profound. Perhaps football managers arrived at the idea of chewing gum by accident, but they seem to be on the right track”. 

(3) Playing video games helps relieve pain

Many individuals that do not play video games view the activity as a complete waste of time and potentially addictive. While excessive video game playing may cause problems in a minority of individuals, there is lots of scientific evidence that playing video games can have many beneficial effects. For instance, a number of studies have shown that children with cancer who play video games after chemotherapy take less pain killing medication. Video games have also been used as pain relieving therapy for other medical conditions such as burns victims and those with back pain. This is because playing video games is an engaging and engrossing activity that means the player cannot think about anything else but playing the game (and is what psychologists refer to as a ‘cognitive distractor task’). Pain has a large psychological component and individuals experience less pain if the person is engaged in an activity that takes up all their cognitive mind space. As well as being a pain reliever, there are also many studies showing that playing video games increase hand-eye co-ordination, increase reaction times, and have educational learning benefits.

(4) Eating snot helps strengthen the immune system (maybe)

How does it make you feel when you see someone picking their nose and then eating what they have found? Disgust? Contempt? Amused? In 2008, Dr Friedrich Bischinger, an Austrian lung specialist, claimed that picking your nose and eating it was good for you. He claimed that people who pick their noses with their fingers were healthy, happier and probably better in tune with their bodies than those who didn’t. Dr. Bischinger believes that eating the dry remains of what you pull out of your nose is a great way of strengthening the body’s immune system. He explained that in terms of the immune system, the nose is a filter in which a great deal of bacteria are collected, and when this mixture arrives in the intestines it works just like a medicine. He said that “people who pick their nose and eat it get a natural boost to their immune system for free. I would recommend a new approach where children are encouraged to pick their nose. It is a completely natural response and medically a good idea as well”. He went on to suggest that if anyone was worried about what other people think, they should pick their noses privately if they want to get the benefits.  This view is also shared by Dr. Scott Napper, a biochemist at the University of Saskatchewan. He theorises that hygiene improvement has led to the increase in allergies and auto-immune disorders and that eating snot may boost the immune system by ingesting small and harmless amounts of germs into the body. The same theory has also been applied to another bad habit – biting fingernails – because again, the act of biting nails introduces germs directly into a person’s orifices.

(5) Daydreaming helps problem solving

Daydreaming is something that can occupy up to one-third of our waking lives and is often viewed as a sign of laziness, inattentiveness and/or procrastination. However, scientific research has shown that the ‘executive network’ in our brain is highly active when we daydream. A study carried out by Professor Kalina Christoff and colleagues and published in the Proceedings of the National Academy of Sciences found activity in numerous brain regions while daydreaming including areas associated with complex problem solving. These brain regions were more active while daydreaming compared to routine tasks. It is believed that when an individual uses conscious thought they can become too rigid and limited in their thinking. The findings suggest that daydreaming is an important cognitive state where individuals turn their attention from immediate tasks to unconsciously think about problems in their lives. Christoff says that “when you daydream, you may not be achieving your immediate goal – say reading a book or paying attention in class – but your mind may be taking that time to address more important questions in your life, such as advancing your career or personal relationships”. In addition to this, Dr. Eric Klinger of the University of Minnesota has argued that daydreaming also serves an evolutionary purpose. When individuals are engaged on one task, daydreaming can trigger reminders of other, concurrent goals so that they do not lose sight of them.
