Is it OK to sleep lots?

Published in Sleep Health 3 mins read

No, sleeping excessively is generally not okay and can indicate underlying health issues.

While getting enough sleep is vital for overall well-being, sleeping "lots" or excessively can be detrimental to your health. According to research, regularly sleeping for more than nine hours each night could be a sign of a potential problem. It may point to a sleep disorder, an underlying mental health issue, or even another health condition requiring attention. Moreover, excessive sleep, like too little sleep, can negatively impact various bodily functions.

The Negative Impacts of Sleeping Too Much


Impact Category Specific Effects
Immune System Can weaken your body's defense mechanisms, making you more susceptible to illness.
Mental Health May exacerbate or contribute to issues like depression and anxiety.
Heart Health Can potentially increase the risk of developing heart-related problems.
Chronic Diseases Long-term excessive sleep is associated with an increased risk of chronic illnesses.


Why too much sleep is harmful:

  • Disrupted Sleep Cycle: Over-sleeping can disrupt the natural sleep-wake cycle, making it harder to fall asleep at the desired time and potentially leading to daytime drowsiness.

  • Increased Fatigue: Paradoxically, sleeping too much can actually make you feel more tired and lethargic during the day, not refreshed.

  • Lack of Motivation: You might find it harder to be productive or engage in daily activities if you're constantly feeling the effects of over-sleeping.

When to be concerned about your sleep:

  • Consistently sleeping over 9 hours: If you consistently sleep more than nine hours each night without feeling refreshed or feeling excessively tired during the day, it's best to consult a medical professional.
  • Significant changes in sleep patterns: Noticing a significant change in your sleep patterns, like abruptly needing much more sleep, should warrant investigation.
  • Associated symptoms: If excessive sleep is accompanied by other symptoms like mood changes, daytime fatigue, or difficulty concentrating, seek medical advice.

In summary, while sufficient sleep is crucial for good health, sleeping "lots" can be harmful, possibly indicating underlying issues. Maintaining a healthy sleep routine and consulting with a doctor about any concerns regarding sleep patterns is always recommended.
