Sleep is naturally recurring state of mind and body characterized by altered consciousness, relatively inhibited sensory activity, inhibition of nearly all voluntary muscles, and reduced interactions with surroundings. It is associated with a state of muscle relaxation and reduced perception of environmental stimuli.
Lack of sleep is a problem for every person. Physical tiredness is not the only problem we have if we do not sleep enough time. It can also lead to lack of appetite, difficulty to think clearly, to make decisions and even to concentrate.
Many experts have also proved that if you have sleeping problems it can also cause numerous health issues. The heart health can be endangered if you sleep less than 5 hours. Diabetes, obesity and weight gain are a result of sleeping less than 7 hours.
In order to preserve our health and promote proper development our body needs to rest, so you must know how much time is enough for your body to rest and sleep.
Here is how many hours of sleep your body needs in order to maintain good health, mental clarity and to have enough energy during the day.
One research has been conducted by Charles Czeisler — a professor at Harvard University, in order to establish the exact amount of sleep that is recommended.
According to the different stages of development, these are the recommended hours of sleep:
- Newborn (0 to 3 months): 14 to 17 hours.
- Babies (4 to 11 months): 12 to 15 hours.
- Children (1-2 years): 11 to 14 hours.
- Preschool (3-5 years): 10 to 13 hours.
- School age (6-13 years): 9 to 11 hours.Teens (14 to 17) : 8 to 10 hours.
- Youth (18-25 years): 7 to 9 hours.
- Adults (26-64 years): 7 to 9 hours.
- Seniors (over 65 years): 7 to 8 hours.
These are not the exact hours. So everyone has its own way to determine the number of hours his body needs. But the number of sleep below the recommended hours of sleep can increase the changes of health problems.
