Medi-Trivia Vol. 4: How much sleep do you really need?
Sleep is for the weak, as they say. Well, yes! Sleep is for the weak because weak people are those who are in need for sleep. Sleep is the natural recurring state of our mind and body which is characterized by altered consciousness, inhibition of sensory activity, voluntary muscles and reduced interactions with surroundings. Sleep is one form of rest to exhaust our the stress and tension of your system.
Sleep plays a vital role when it comes to memory, both before and after learning a new task. That is why it is effective to study right after your wake up. Lack of adequate sleep affects mood, motivation, judgment and our perception of events. When we are sleep deprived, our over-used neurons can no longer function at its best to coordinate information properly thus we lose our ability to access previously learned information.
So how much sleep do your really need?
The number of hours for sleeping varies from person to another depending on its age. The National Sleep Foundation has come up with recommendations from newborn to older adults:
- Newborns (0-3 months ): Sleep range narrowed to 14-17 hours each day
- Infants (4-11 months): Sleep range widened two hours to 12-15 hours
- Toddlers (1-2 years): Sleep range widened by one hour to 11-14 hours
- Preschoolers (3-5): Sleep range widened by one hour to 10-13 hours
- School age children (6-13): Sleep range widened by one hour to 9-11 hours
- Teenagers (14-17): Sleep range widened by one hour to 8-10 hours
- Younger adults (18-25): Sleep range is 7-9 hours
- Adults (26-64): Sleep range is 7-9 hours
- Older adults (65+): Sleep range is 7-8 hours
What happens when I overslept?
Too much of something is a bad thing, even on sleeping. The same thing with being sleep deprived, oversleeping also messes up with out circadian rhythm that is why even we say that we had a long good sleep, we still feel groggy. Some health impacts on oversleeping are - cognitive impairment, depression, impaired fertility, higher risk of obesity, diabetes or even a higher all-cause mortality.
Too much or too little can be hazardous to your health. Develop a sleeping schedule, keep your room comfortable and minimize the use of electronic gadgets for a good sleeping habit.
