A hot shower kills your fatigue

After a day's tiring work, many go home and hit the bed. But you might as well take a hot bath before that to refresh yourself.

After you get up in the morning, it is best to take a shower. This helps awaken your mind and body and let you devote yourself into the work and study. If you feel tired in the evening, you can take a hot shower 1 ~ 2 hours before sleeping. It can accelerate the blood circulation, improve metabolism of the body and make you full of energy.

Research has shown that after strenuous exercise, taking a shower for five minutes makes no difference in the blood lactate concentration. If for ten minutes, the lactic acid concentration will decrease by 7 ~ 8 mg; but if for 30 ~ 60 minutes, lactic acid concentration will be the same as before the shower. For general workers or minor workers, taking a shower for 15 minutes, the lactic acid concentration in the body can return to normal level, otherwise if the time is long, itr will consume energy and fatigue will come back.
