Should sleep deeply and fully every night

Canadian researchers say lack of sleep makes people more irritable for their colleagues or family members. Research results show that men are more willing to suffer colleagues due to lack of sleep while women prefer to vent anger in their families.

In addition, people who lack sleep also work less effectively than others. The average time of a full night's sleep is 7-8 hours, but it seems that few adults currently achieve it for subjective and objective reasons.

The lack of sleep accumulates every day and people always tell themselves to 'pay back' with the weekend. But doctors warn: a long sleep on the weekend can not compensate for the loss of health during the week due to the pressure of life and lack of science.
