We have all had those mornings when getting out of bed was a literal struggle. Modern research has proven that inadequate amount of sleep can actually lead to conditions like obesity, diabetes and insomnia. Studies have shown that chronic insomnia can heighten your risk for depression and high blood pressure. Moreover, a 2002 study found that women are more susceptible to insomnia than men. The amount of screen time before sleep has been noted to affect the circadian rhythm linked to sleep. Light exposure from screen just before going to bed lowers the level of the sleep hormone melatonin, negatively impacting the quality of sleep. About 10 million people use sleeping pills. The problem is more serious than you think.
