So should you walk up at 5 am and go out for a run? Ben Franklin said that “Early to bed and early to rise, makes a man healthy, wealthy, and wise”. In the Military, early morning fitness is the norm, but is it the right thing to do?
- Obesity and BMI: One research study shows a relation of poor sleep and obesity,. Because sleep duration is a potentially modifiable risk factor, these findings might have important clinical implications for the prevention and treatment of obesity. The relationship does not indicate a causative relationship. More studies are needed. Another study among Chilean nutrition students found an association between fewer hours of sleep and higher body mass in this population; this should be considered in excess weight prevention.
- Calorie Intake: A study in Quebec found that subjects that slept 5-6 hours or less were more likely to experience weight gain. The study also found the same to be true for those that step too many hours (9-10 hours or more). It is clear that there is a metabolic ramification to both poor and excess sleep. Another study shows sleeping less was associated with excess weight or obesity and suggest that restricting sleep may lead to weight gain via increased food intake.
- Weight Gain: A study in the American Journal of Epidemiology showed women who slept seven or more hours a night were less likely to put on weight than women who didn’t. Those who slept only 5 hours a night were 15 percent more likely to gain substantial weight.
What is clear is that loss of sleep no only effects out ability to perform, but it also like effects metabolism and results in weight gain. If you like to talk an early morning run at 5 am, I recommend that you go to sleep at 9-10 p.m. Don’t sacrifice your rest and for exercise. Quality matters more than quantity, so taking a nap may not help. Good restorative sleep will help
