The short term effects of sleep deprivation are well documented; cognitive fog, reduced alertness and an impaired ability to regulate emotions, to name just a few. Now, a Swedish study has shed more light on the potential long term effects of sleep loss.
According to new research from Uppsala University in Sweden, clocking up approximately four and a half hours of sleep for three nights in a row is enough to increase your risk of heart disease. Scientists discovered that three nights of poor sleep results in changes in the blood, which in turn elevates the risk of cardiovascular disease.
