Sleep Enough
Lack of sleep makes you feel tired and angry, you can’t concentrate your attention. Lack of sleep can damage your physical health (especially heart) as well [1]. Some studies have shown that 8 hours of sleep per 24-hour period is the average requirement for adults. But all people are different and need for sleep can range from 6 to 10 hours. If you feel sleepy during 4pm and 6pm, you probably do not get enough rest
