Do you sleep properly? If not, then you’ d better start doing it. Getting enough sleep is vital for health and productivity.
Loss of sleep can cause, among others, loss of reaction abilities. Eight hours of sleep per day are fine, but if you sleep six hours then the possibilities of reduced reaction abilities are increasing. Moreover, too much sleep -more than 9 hours- can also be harmful for our health, so try to find the balance somewhere in the middle!
