Good Health Good Life
There are two stages of one's sleep:
REM (Rapid Eye Movement)-contributes to mental consolidation
Non- REM-Aids physical repair and rebuilding
During a typical night, one alternates between the above two stages approximately 4-5 times. Insufficient number of hours of sleep contributes to:
Mental irritability (5-6 hours of sleep) due to lack of REM sleep
Physical tiredness (<5 hours of sleep) due to lack of non-REM sleep
ATHLETES: You need to bear in mind that in case you are a runner, your body needs an extra hour of sleep to repair any running related tissue/cell damage.
