Happy sleep quality is closely related to overall physical and mental health, but is it harmful to you to sleep too much? According to a study published in PLoS one, oversleep and lack of sleep are associated with an increased risk of chronic diseases (including coronary heart disease , 2 diabetes , anxiety and obesity) in adults over 45 years of age.
But why is sleep important? It is crucial to regulate the body's metabolism and hormone processes, and it can also achieve recovery goals by excreting the toxins accumulated in the brain. Sleep also enables specialized immune cells to fight infection more effectively, thereby strengthening our immune system.
But if you sleep too much, you may still feel tired and drowsy when you wake up. CDC (CDC) recommends adults 7 to 9 hours, teenagers 8 to 10 hours, and newborns 14 to 17 hours. Diabetes patients often feel tired due to high or low blood sugar levels, so to stabilize their condition, they should sleep for at least seven hours a night.
According to a study published in the journal Sleep, sleeping for more than eight hours may have adverse effects on the brain. Neuroscientists from the Institute of Brain and Mind at Western universities have found that excessive eye closing can reduce cognitive and reasoning skills. The study found that people who slept 9 to 10 hours a night were 21% more likely to become obese within six years than those who slept 7 to 8 hours a night. Even considering food intake and exercise, the link between sleep time and obesity is the same.
