Feeling lonely or shy? Go exercise.- daily
Steve over on Games Are For Children posted about his experiences with shyness and overcoming it, and an abstract from a paper:
Now, this does not say anything if this is cause or effect. However, there are several effects from exercise that seems likely to contribute this way:
The purpose of the current study was to estimate the relationship between exercise frequency and measures of shyness and loneliness in a sample of 882 college students. Analysis provided evidence that higher shyness and loneliness scores were associated with not exercising and infrequent exercising. Also, subjects who exercise 7 times a week scored significantly lower than the other exercise-frequency groups. Analysis of covariance, controlling for possible confounding variables, gives further support.
- Hormonal: Exercise burns cathecolamines (adrenaline and noradrenaline), which also lead to lower production of cortisol. Overall, this means lowered stress level.
- Hormonal: Exercise tends to regulate sleep, leading to more energy. (This may be the same effect as above, though I seem to remember an additional regulating effect on melatonin.)
- Physical/hormonal: Exercise regulates hunger appropriately, leading to more energy.
- Physical/Mental: Exercise leads to production of new brain cells, which seem to be involved in curing depression. Thus, more positive feelings/filters overall.
- Social/Physical: Exercise leads to looking better/healthier, which again gives more positive social feedback.
- Social: Many forms of exercise includes some social activity directly.
