The easiest way to lose weight and improve your overall health may be to get enough sleep. Recent studies show that when you get insufficient sleep over a long period of time, it can compromise your immune system.
Researchers at the University of Chicago found that volunteers who slept just four hours a night for a week upset their hormonal and metabolic systems. This meant that although theoretically being active for longer hours burned more calories, the changes in hormone levels lead to increased appetite and increased food consumption.
They concluded that chronic sleep loss hastened the onset of health problems like diabetes, high blood pressure and obesity. Another study showed that getting insufficient sleep can increase your chances of getting a heart attack.
If you've been cutting down on your sleep, the best thing you can do for your health and fitness is to ensure that you get your full eight hours every night.
