Why brain is much more active at night ?
Researchers believe that brain is more active at night than day. According to them, the brain organises, classifies and stores the information received during the day at night. The repairing of body cells/tissues also occurs during the night under the control of brain. This involves complex processes of the brain and use of lots of energy. Thus, brain also needs to control and regulate metabolic process like respiration, circulation at night to supply the energy for these complex processes. Because of all these activities, the researchers?believe that brain is more active at night than day.
