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.

  1. I used to write for a sleep website and I agree with what you said. A lot of people feel proud when they do things even without sleeping - not knowing that it will do them more harm than good. In truth, I used to be one of them. Hehe. My motto was once "sleep is a luxury I can't afford right now" but I've honestly changed that because I noticed that I can't concentrate when I lack sleep, plus I'm cranky.

    So now although I still have sleepless nights or days becausw of uncontrolled circumstances like binge-watching (haha), I value sleep more than ever.

  2. I agree with you on that. I tried sleeping too much and every time I woke up, I feel "kapoy". That shouldn't be the case since I had more than 10 hrs of sleep. haha

  3. It's weird because I don't feel like anything after sleeping for the entire day. Hahaha! Maybe I'm still a toddler that needs 14-17 hours of sleep. Hahaha

  6. I'm 23 years old but I still sleep for 10-12 hours a day. If it's lesser than that, I am simply unable to function properly for the whole day. A sleeping schedule and a comfortable room is extremely important.

  9. One of the things I'm really thankful for ever since I became much less occupied with work is how I can get some proper sleep. Back then I was lucky to even get 6 which I'm completely aware to be unhealthy. Sleep really is such an important thing and should always be prioritized.

  10. OMG!I thought having 5 hours of sleep is enough. I am 27 years old already and I thought 5 hours is good for me. Thanks for this, now I know I have to sleep 7 to 9 hours a day :)

  11. After being deprived of sleep, I can sleep for more than 12 hours and still feel good after waking up, but I can also stay awake for more than 40 hours without sleep. Usually my sleeping hours lately is just about 4-6 hours. So that means, my life span is getting shorter everyday. Like ToTem, my life on earth seems really is shortened, so send me blue flowers then? HAHAHA.. just kidding.

    But yes, our body really deserves that right amount of sleep. And I must sleep now. :)

  12. Sleeping is a major concern when it comes to space travels. Hahahaha. I hope we can sleep for 25 years and just be in our normal selves after that time. But, we ask ourselves, how can we sleep if daghan buhatonon?

  13. I think there is also such a thing as high quality sleep and low quality sleep. I think 5 hours of high quality sleep can bear 8 hours of low quality sleep. Sleep is really important and it is a luxury for some. Sweet Dreams!!!
