Oversleeping: What happens when you sleep too much?


You might be amongst the many people who are excited about the holiday period, because you finally got the time to rest. Unsurprisingly, you might be tempted to sleep long hours this period in a bid to make up for sleep lost during work days. Unfortunately, this article might just burst your bubble. This is because many industry experts have associated oversleeping with certain medical conditions which you don’t want to experience. While we have continuously emphasized on the need for adequate sleep, still, oversleeping can be detrimental to your health.


The quantity of sleep you should get is largely determined by your age. Although, there are certain sleep conditions that might make you sleep longer than the recommended time. However the rule of thumb is to snooze within the recommended range for your age, and not to doze much more than( 9hours for adults) or far below(9 hours for adults)the recommended sleep range. Below is the recommended sleep duration by the National Sleep Foundation:

  • Newborns (0-3 months): Sleep duration between 14 and 17 hours each day (Previously it was 12-18 hrs)
  • Infants (4-11 months): Sleep range is extended from 12 to 15 hours (Previously it was 14-15)
  • Toddlers (1-2 years): Sleep range broadened from 11 to 14 hours (Previously it was 12-14)
  • Preschoolers (3-5): Sleep range stretched by one hour from 10 to 13 hours (Previously it was 11-13)
  • School age children (6-13): Sleep range widened by one hour, 9-11 hours (previously it was 10-11)
  • Teenagers (14-17): Sleep range broadened by one hour, 8-10 hours (previously it was 8.5-9.5)
  • Younger adults (18-25): Sleep range is 7-9 hours (new age category)
  • Adults (26-64): Sleep duration remains 7-9 hours (Previously also it was 7-9 hours)
  • Older adults (65 and older): Sleep range is 7-8 hours (new age category)

What Happens When You Oversleep?

Of course, too much of everything is bad and this includes too much sleep. Here are the health effects of oversleeping:

  • Excess Weight Gain

Nobody wants to be out of shape, do you? The truth is that, You are more likely to be obese when you sleep continuously sleep beyond the appropriate time. A study has shown that long sleepers- people who slept over 9 hours are 21% more likely to become overweight  than people who slept within the recommended range. Therefore, we can rightly say that too much sleep can make you fat.

  • Stroke

A 2019 study published in the online issue of Neurology reports that those who sleep for more than 9 hours at night had a 23% higher risk of stroke than those sleeping less than eight hours each night. Additionally, it also found that people who nap for at least 90 minutes have a 25% stroke risk than those who nap for less than 30 minutes.

  • Headaches

Too much sleep can trigger headaches especially for people who are prone to headaches and back pains. We strongly discourage Snoozing longer than the usual time regularly, whether it’s during the week, weekend or taking advantage of the holiday period to oversleep.  It’s safer to stick to a regular sleep schedule and not to oversleep. Notable amongst the many explanations on why oversleeping causes headaches is its effect on a neurotransmitter-serotonin.  Generally, serotonin helps induce sleep and keep you awake, and any interruption in the activities of the serotonin will result in headaches.

  • Heart Diseases

People who have excess amounts of sleep are prone to heart complications. Result from the Nurses’ Health study have shown that women who sleep more than 9 hours per night were 38% more likely to have coronary heart disease than women who slept eight hours.

  • Depression and Anxiety

Staying in bed longer than recommended can result in hormonal imbalance, making it difficult for your body to regulate stress. Example of such a hormone is the cortisol. The cortisol is a stress hormone released by the adrenal glands; it helps your body deal with stressful situations. However, if you do not stick to a normal sleep pattern, the activity of this hormone may be interrupted; affecting its ability to manage stress and consequently result in the buildup of anxiety and depression overtime.
