The Unexpected Risks of Oversleeping

May 21, 2019

How oversleeping impacts your health & wellbeing

We’ve all been there - the alarm goes off, and you know you need to get up, but you hit that snooze button once or twice (or six times) because you are all cosy in that space between sleeping and waking. Having a bit of a lie-in every now and again is pretty normal, but did you know that chronic oversleeping is actually just as bad for your health and wellbeing as a lack of adequate sleep?

According to renowned international sleep experts, such as Michael J. Breus, PhD, DABSM, you can actually sleep too much and it is likely to have both short-term and long-term effects on your health if you don’t address the issue.

Individuals who sleep too much are more prone to develop a propensity for, or suffer from, the following conditions:

Impaired Brain Functioning

Data gleaned from the Lumosity brain-training platform suggests that cognitive performance peaks at around 7 hours of sleep per night, tapering off with both and less. Additional studies have found links to oversleeping and the risk of dementia, as well as memory impairment in general.


There is a very complex relationship between sleep and depression. Irregular and disrupted sleep is both a symptom of and a contributing factor to depression. It also worsens the other symptoms of depression and makes it harder to treat. The tie between the two is still being investigated, but so far we do know that irregularities in the circadian rhythm can have an impact on the disease and that the establishment of a healthy sleeping pattern is in an important aid in the course of treatment.

High Risk of Stroke & Heart Disease

Because oversleeping is often linked to sleep fragmentation, fatigue, lower immune function (due to the expression of cytokines), a lack of exercise and underlying disease like sleep apnea, oversleepers are also more likely to be at higher risk of heart disease and stroke.

These are just a few of the ways in which oversleeping can impact your health and wellbeing in the long run. If you find yourself sleeping excessively and still feeling tired throughout the day, it is important to consult with your physician. Changes in your sleep patterns and -requirements are often connected to other health conditions that need to be addressed. Get to the root of the situation as soon as you can so you can go back to living an active, vital life.
