"Where are the tips? I would call these results from studies, or interesting facts, but not tips. Interesting but not helpful "
Tip 11. According to a study in the Journal of Applied Physiology, light from computer and smartphone screens may suppress production of melatonin, a sleep-inducing hormone triggered by darkness. Artificial light also shifts your circadian rhythms—a biological cycle that responds primarily to daylight and darkness and influences sleep.
Tip 12. One two-year study of more than 10,000 middle-aged men and women found that sleeping less than 6 hours per night (or more than 9) was linked with feeling sad and anxious. Too little sleep may cause changes in brain chemicals that fuel depression.
Tip 13. Research has found that middle-aged adults who regularly sleep less than 6 hours a night are almost doubling their risk of developing high blood pressure compared to those that sleep the recommended 7-8 hours per night.
Tip 14. A recent study out of Harvard shows if you’ve missed an hour or two of sleep, you’re more likely to give in to junk food the next day. The prefrontal cortex—part of the brain responsible for self-control—is compromised by sleep loss.
Tip 15. Research indicates that even one night of low-quality sleep (i.e., restless sleep) or low-quantity sleep (less than 6 hours) can cause an increase in insulin resistance, a major contributor to the development of type 2 diabetes.
