The National Sleep Foundation made a list of hours, which shows how much should a person sleep according to his/her age.
If you lack sleep and the rest that the body needs, you may experience some difficulties when you try to think clearly, inability to make decisions and concentrate and weight loss.
There are many health problems that can arise as a result of sleeping issues. If you are a person who sleeps less than five hours, you have an increased chances of heart diseases, and if you sleep less than seven hours, you may experience diabetes and problems with your weight.
It is of vital importance that you get the sleep that you need every night, and that way you can be full of energy, you will be able to do your daily tasks without problems with the concentration, and you will be able to support your overall health.
A study was conducted by Charles Czeisler, a Harvard University professor, where he aimed to estimate the time that every person needs to spend sleeping. He took the results from multiple studies that were conducted previously and made up a chart according to the different development stages:
- 0-3 months (newborn) 14 to 17 hours
- 4 to 11 months (babies) 12 to 15 hours
- 1-2 years (children) 11 to 14 hours
- 3-5 years (preschool) 10 to 13 hours
- 6-13 years (school age) 9 to 11 hours
- 14 to 17 years (teens) 8 to 10 hours
- 18-25 years (youth) 7 to 9 hours
- 26-64 years (adults) 7 to 9 hours
- Over 65 (seniors) 7 to 8 hours
These sleep hours vary between different individuals.
Sleep issues can often times occur as a result of the technology and stress. When stressed, the levels of cortisol (the stress hormone) in the body increase, and will deprave you from the sleep that you desperately need.
Also, technological devices emit light that can prevent the release of melatonin. This can also lead to troubles when it comes to sleeping. Melatonin is very important for sleeping, and it is released when it is dark.
