Each person has different sleeping needs. Some people operate at their best after 9 hours while others seem to need just 5 hours each night. However, people who sleep the same amount of time each night, live longer on average than people who adjust their schedules, to either add or subtract hours from their nightly slumber (2007, British study)
Finding your own ideal sleep/wake cycle – and staying consistent – is key to healthy sleep, agrees Carol Ash, D.O., medical director of the Sleep for Life center in Hillsborough, N.J. According to The American National Sleep Foundation, the younger you are, the more sleep you need, with up to 18 hours recommended for newborns:
- Children between the ages of 5 and 10 should get between 10 and 11 hours of sleep each night,
- Teens should get between 8.5 and 9.25,
- Adults between 7 and 9 hours. Although some adults conditions are extremely different. Some get satisfied with 5 hour of sleep and some need 10 hours of sleep. This depends on the work and and the type of work they do. For example, those who are very active, they may need more.
- Pregnant women need some more hours of sleep per day in the first three months of pregnancy.
- Those who are ill, their body can use the additional rest to heal and strengthen their immune system.
