The idea that we need eight hours of sleep each night might be just as irrelevant as the myth that we need to drink eight glasses of water a day.
Two new studies revealed that we should sleep at most and at least seven-and-a-half hours every night.
In one study that measured the results of over 42,000 men in China between the ages of 41-50, researchers found that men who slept less than seven hours a day were 39 percent more likely to die of lung cancer than those who slept eight hours.
Additionally, those who slept 10 hours or more were more than twice as likely to die of lung cancer.
Researchers who performed a similar study in Finland found that men who slept less than seven hours a night were one-and-a-half times more likely to develop dementia due to the reduced secretion of melatonin.
How much you sleep effects your body’s production of hormones which in turn effects levels of inflammation and the acceleration of tumor growth.
Sleep deprivation has also been linked to higher amounts of copper in the blood which also increases the risk of cancer.
