We spend about a third of our life sleeping. The average adult sleeps 7 to 8.6 hours a day. Children
sleep more than adults; they spent about 10 hours a day sleeping. Newborns, however, may sleep for nearly two-thirds of their day. There is an age-related difference in average time spent sleeping. As a person ages, they require less sleep. The elderly only spent around 6.5 hours a day sleeping.
The amount of time spent sleeping may be genetically influenced. Deprived of sleep, we run the risk of fatigue; depressed immune system; impaired concentration, creativity, and communication; irritability; and deteriorated performance. In the long-run, sleep deprivation may contribute to obesity, hypertension, and memory impairment.
