Medical Video: The science of how much sleep you actually need
Even if you sleep at home at the same time as your child, brother, sister or parent, not necessarily how long you can sleep is the same.
Lydia DonCarlos, PhD, from Loyola University Chicago Stritch School of Medicine is one of the experts who makes recommendations on how much sleep a person needs. The panel, which is led by the National Sleep Foundation, makes recommendations based on age, starting with newborns (who need 14-17 hours of sleep per day) to adults aged 65 years and over (7-8 hours per day).
The results of this study indicate that adolescents aged 14-17 years need 8-10 hours of sleep per night. This figure is higher than the previous recommendation of 8.5-9.5 hours per night.
Dr. DonCarlos and other experts in a multidisciplinary panel examined findings from 320 studies that reported sleep duration, and they found a health effect from the duration of sleep, which is a consequence if too long or too little sleep. The results are published in Sleep Health: Journal of the National Sleep Foundation.
"The process is very thorough," said Dr. DonCarlos, who represents the American Association of Anatomists from 6 sleep experts selected by the National Sleep Foundation.
"We still have to undergo further research to study the sleep function. We know that sleep is refreshing and important for memory consolidation, but we don't know in detail what the function of sleep is, even how we can spend our lives just to sleep, "Dr. DonCarlos.
How long is the ideal sleep time for me?
Although each age group has been grouped according to how long their recommendations for time to sleep, the National Sleep Foundation in its main report is at Sleep Health Journal, mentioning that there is no perfect amount of time for everyone. Here are recommendations for sleep hours:
- Newborns (0-3 months): 14-17 hours every day
- Babies (4-11 months): 12-15 hours every day
- Toddlers (1-2 years): 11-14 hours every day
- Pre-school (3-5 years): 10-13 hours every day
- School age (6-13 years): 9-11 hours every day
- Adolescents (14-17 years): 8-10 hours every day
- Young adults (18-25 years): 7-9 hours every day

With enough sleep, our health will be better and maximum. All organs that are tired of working certainly need rest periods, including the brain, skin, metabolic system, and hormones. During sleep, information that enters the brain will be arranged neatly, so when you wake up you often find a solution to the problem the day before.
Cells in the body will regenerate when we sleep at the maximum level. So not infrequently, if you sleep according to its recommendations, a person's skin will look healthy and tight. In addition, the immune system will also increase because our cells are renewed, and the hormone melatonin which helps strengthen the immune system usually works most effectively at night, when it is dark and we are sleeping.
