Overuse of the brain is not advisable. Otherwise, it would give rise to consumption of qi and blood. Therefore, mental workers should not surpass two hours each time when they bend over their desks working. It is advisable for them to take a rest once every hour for 10 to 15 minutes. The methods for rest may include exercising the body and limbs, taking a deep breathing or thinking long and hard with the eyes closed.

When having prolonged mental work, take care to alternate the working contents. For example, alternate the activities of reading, reading aloud, listening to music and watching pictures. Mental workers may also select the light, soft and slow music as the background to balance the activities of the work of the left brain and the right brain. As a result, the pressure of the thinking center can be relieved. More information, please continue to read Ginseng-(Renshen).shtml">Radix Ginseng (Renshen).
