What difference could an extra hour of sleep make in your life? Maybe quite a lot, experts say. Studies show that the gap between getting just enough sleep and getting too little sleep may affect your health, your mood, your weight, and even your sex life.
If you're getting less than the recommended seven or eight hours of sleep a night, here are nine reasons that you should shut down your computer, turn off the lights, and go to bed an hour early tonight.
1. Better health. Getting a good night's sleep won't grant you immunity from disease. But study after study has found a link between insufficient sleep and some serious health problems, such as heart disease, heart attacks, diabetes, and obesity.
In most cases, the health risks from sleep loss only become serious after years. That might not always be true, however. One study simulated the effects of the disturbed sleep patterns of shift workers on 10 young healthy adults. After a mere four days, three of them had blood glucose levels that qualified as pre-diabetic.
2. Better sex life. According to a poll conducted by the National Sleep Foundation, up to 26% of people say that their sex lives tend to suffer because they're just too tired. There's evidence that in men, impaired sleep can be associated with lower testosterone levels -- although the exact nature of the link isn't clear.
