Sleep is when the body relaxes, the heart slows down, the cells repair, and the brain processes crucial learnings from the day.
But all of this can be done only when the natural cycle of sleep is complete— this takes about seven to eight hours in the
case of adults.
Eight hours of quality sleep is required
for the overall well - being of the body and the mind.Adults over 65 years of age require a minimum of 8 hours of sleep.
