Side effects of oversleeping and how sleep monitoring can help

It's true a good night's sleep is essential and that the lack of sleep can be detrimental to one’s health. But have we ever thought about the other side of the coin? Can too much sleep actually be as bad as the lack of it? In fact, many studies have shown that habitual oversleeping can be linked to physical and mental health complications. But one may wonder how much sleep is too much and can we really get too much of a good thing? While the amount of sleep varies from person to person and depends on a person’s age, the National Sleep Foundation encourages adults to sleep an average of 7-9 hours a night. While many of us struggle to reach those precious hours, there are some that have a habit of oversleeping and who are unaware of the dangers. According to WebMD, here is a quick list of side effects if you’re getting too much sleep:


Studies have shown that sleeping too long each night can increase the risk for diabetes and that people who slept more than 9 hours every night were at a 50% higher risk of having diabetes.

Sleeping too much could make you weigh too much, as well. One study showed that people who slept for 9 or 10 hours every night were 21% more likely to become obese over a six-year period than were people who slept between 7 and 8 hours.


Looks like for people who are prone to headaches, oversleeping can cause head pain. Researchers believe this is due to the effect oversleeping has on certain neurotransmitters in the brain, including serotonin. People who sleep too much during the day and not much at night may also find themselves suffering from headaches in the morning.

Back pain

Contrary to common belief, people suffering from back pain should not sleep to ease the pain. Doctors now realize the health benefits of maintaining a certain level of activity and recommend against sleeping more than usual, when possible.


Depression cases are usually linked to insomnia, but about 15% of people with depression sleep too much. This may in turn make depression worse.

Heart disease

A health study involving 72,000 women showed that women who slept 9 to 11 hours per night were 38% more likely to have coronary heart disease than those who slept 8 hours. The reason for the connection however has not yet been identified.

If you are still not convinced of the potential health dangers of oversleeping, maybe this last side effect will make you think twice! Studies have actually found that death rates are higher in people who slept 9 or more hours at night than those who slept 7 to 8 hours. A specific reason for this link hasn’t been identified, however depression and low socioeconomic status are associated with longer sleep.

Our sleep monitoring solution

Our X2M200 respiration sensor, with its sleep monitoring profile, provides advanced respiration and movement tracking throughout the night. The sensor can help sleepers be aware of their sleep habits and push them to take necessary actions if any irregularities show up or if the total number of sleep hours registered is too low. But after all this research and studies about the dangers of getting too much sleep, we hope that the sensor can also notify sleepers when the number of hours is too high and push them to take action.
