Lack of sleep
Not getting enough sleep can actually shorten a person’s lifespan and this is done in a number of ways.
A study from the Division of Sleep Medicine at Harvard Medical School found “sleeping five hours or less per night increased mortality risk from all causes by roughly 15 percent”.
A lack of sleep may also cause other health issues.
According to the study, there is a link between not getting enough sleep and weight gain leading to obesity.
Additionally, the study reports that insufficient sleep has been proven to lead to diabetes, heart disease, hypertension, a weakened immune system, and mood disorders.
