Although everyone sleeps differently, too much sleep can negatively affect your life. If you have slept more than usual and not know why, it can be problematic. We will look at oversleeping, the causes of oversleeping, and what we can do to reduce our time spent sleeping.

You may need to make lifestyle changes. Otherwise, seeking the opinion of a medical professional is best. See your family doctor and speak to a local sleep specialist. Let them run some tests. They might find out what is affecting you and how to come out on top of oversleeping.

What Is Oversleeping?

Oversleeping, also known as hypersomnia, is when an individual sleeps more than their usual amount or more than the average population.

Sleep is a very individualized experience. This means it varies between person to person. If you regularly sleep 9 to 10 hours and wake up feeling well rested, then all is well. But if you sleep just as long and wake up exhausted, it might be time for a check up with the family doctor. Sleeping more and feeling exhausted can mean there might be an underlying health concern that needs to be addressed. 

How Much Sleep Is Too Much Sleep?

Some people may feel well-rested and ready for their day after 6 hours of sleep. Others might need 10 hours. Although the chart above are recommendations or may be appropriate for each age group, it doesn’t mean everyone sleeps the same way.

Is sleeping too much bad? Not necessarily. If you sleep a certain amount and wake up feeling refreshed, then that might be the perfect amount of sleep you need. If you are sick or is ill, you might sleep much more than you normally do. Your diet, physique, stress and age also plays a role.

If you need over 10 hours of sleep and feel fatigue, it might be worth getting the opinion of a medical profession to check for any underlying health condition that might affect you. Feeling exhausted during your day and needing an extra sleeping session or two can also warrant a check up. A physician or sleep specialist should also examine you if there are sudden changes to your sleep patterns, such as sleeping longer than usual or more frequently.

If you find oversleeping consistent, a lifestyle change might be in order.

What Happens When You Sleep Too Much?

Sleeping is a low energy activity. To fall asleep, your body needs to relax and feel tired to do so. Being in an indefinite state of exhaustion isn’t healthy, and can come with side effects. The most common side effects of oversleeping are anxiety and depression, low energy, and memory problems.

As oversleeping becomes prevalent, other health risks associated with it include:

  • headaches
  • obesity
  • diabetes
  • back pain
  • depression
  • heart disease
  • increased risk of death

What does this look like for your daily activities? Here are some examples of the challenges you might face day-to-day:

  • excessive worrying throughout the day
  • feelings of numbness and inability to feel joy or happiness
  • unable to attend social gatherings or keep up in social conversations at work, with friends and family
  • early onset of exhaustion after waking up and inability to do daily tasks
  • excessive and impulsive eating, and weight gain
  • trouble thinking clearly and brain fog

  • increase in forgetfulness and misplacement of keys, wallets, and other personal effects

Oversleeping might feel obvious if you are doing it. To help you and your physician diagnose your condition and get you the help you need, there are steps you can take to understand your sleep condition:

  1. Rating yourself on the Epworth Sleepiness ScaleA widely accepted test used in sleep medicine. The goal of the test is to subjectively measure your sleepiness. There are 8 questions, giving you a series of scenarios and asking for your judgement on your likelihood of falling asleep in each. Take this test then hand off your answers to your family doctor and sleep specialist for their review.
  2. Log your sleep in a sleep diary: We want to know how much you sleep, how often you fall asleep during the day, and how you feel after waking up. Rating how well you sleep each time on a scale of 1 to 10 will be a useful insight. You can bring your sleep diary log to your family doctor and sleep specialist for their review.
  3. Booking a polysomnogram at a sleep clinic: Also known as a sleep study, a polysomnogram can help diagnose sleep disorders. You would spend a night sleeping at the clinic with sensors connected to your body. These sensors are then connected to a machine that track physiological changes throughout your body, such as your brain waves, oxygen level in your blood, heart rate, breathing, and eye and leg movements. A sleep specialist can then review the results and produce a sleep study report for you.
  4. Taking multiple sleep latency tests: This test measures how quickly you fall asleep, and is done after a polysomnogram, It can take a full-day, with 4 or 5 scheduled naps separated by two-hour breaks. The same polysomnogram sensors are placed along your body to transmit data and track physiological changes.

Knowing where you are with your sleep health is important. These 4 steps can provide insights for medical professionals to diagnose any possible underlying health condition that might cause oversleeping. They can also help you understand what is going on in your body so you can take measures to improve your oversleeping condition.

Caffeine and nicotine are stimulants that increase alertness and can keep you from falling asleep. Alcohol is a depressant that causes drowsiness, but negatively affects your quality of sleep. This means waking up feeling groggy and unrested!

It can also keep you alert when you are feeling drowsy during the day. Get some fresh air, exercise for 15 minutes a day, and celebrate your physical health. Exercise can be as simple as a 15-minute brisk walk outdoor or a brief yoga session.
