Why does sleeping too much cause headaches?

One potential cause of headaches from oversleeping is disrupted sleep and circadian rhythms. If a person normally sleeps for 7 hours but suddenly sleeps for 9 hours, especially at a different time than usual, the body's natural circadian rhythms will be disrupted. This results in headaches upon waking.

Therefore, people need to have a regular sleep routine and stick to it, even on weekends or holidays, according to the health information site Everyday Health (USA).

Sleeping too much can disrupt your circadian rhythm and cause headaches when you wake up.

Another explanation for headaches related to too much sleep is dehydration. While we sleep, our bodies continue to lose water through breathing and sweating. If you sleep for a long time, your body will become even more dehydrated, leading to headaches when you wake up. To prevent this, people need to drink enough water throughout the day, consider drinking a glass of water before going to bed and right when waking up.

Additionally, sleeping too much can contribute to a condition called sleep intoxication. This occurs when you suddenly wake up from a deep sleep, leaving you disoriented and with a headache. To prevent sleep intoxication headaches, people should establish a regular sleep schedule with consistent wake-up times.

For optimal health, a balanced sleep of 7-9 hours a night is needed.

Additionally, sleeping too much is linked to increased inflammation in the body. Inflammation can cause headaches because it affects the blood vessels and nerves in the brain. Furthermore, sleeping too much also disrupts the balance of neurotransmitters, such as serotonin, which plays an important role in regulating pain sensation. This imbalance can contribute to headaches.

Finally, headaches caused by excessive sleepiness can be a sign of an underlying sleep disorder, such as sleep apnea. Sleep apnea can reduce the amount of oxygen reaching the brain. This can result in headaches and dizziness upon waking.

If a person experiences frequent headaches when sleeping too much, they should talk to their doctor. The doctor can determine the cause and make appropriate recommendations for treating the pain. One thing everyone should remember is that sleep plays an important role in health. Therefore, for optimal health, a balanced sleep of 7-9 hours a night is needed, according to Everyday Health .
