Headache / brain fog after long sleep

  1. Why do I often get a brain fog / headache when oversleeping?
  2. How to prevent it?
  3. How to cure it when it happens?

See no correlation with supplements or diet.

There is definitely no correlation with the actual time I go to sleep and wake up.

Interestingly, I often feel terrific for the first couple of hours of waking up. But then it starts and might last for many-many hours.

I also feel very dehydrated in these cases (despite drinking couple of glasses of water pre-bed and 3 glasses of water immediately after waking up). But drinking a lot doesn't help. Sugar, salt, vitamins - nothing seems to help it.

I usually sleep about 8hrs a night, but that's not enough for me. But when I try to compensate with 10/12 hrs sleep, I'm quite likely to get these "side effects" that feel terrible.

I don't know what you've tried before supplement or diet wise but if I were in your shoes I would try a simple experiment to reset my circadian rhythm (hormonal clock).

  1. Try not to eat within 2 hours of going to sleep.

  2. Go to sleep by 10pm

  3. Try not to view any artificial light within an hour of sleeping. I use special goggles that block green and blue spectrum light.

  4. Wake up with the sun and eat a high protein meal within 30 minutes.

  5. Walk outside barefoot and do some stretches, check the mail, etc etc.

Try that for 2 weeks and see what happens.

This might be a stretch, but have you considered air-quality and oxygen levels in your bedroom?

The issue may not be sleeping too long (length of sleep) but sleeping too late. Time of sleeping/waking can influence mood profoundly. http://evolutionarypsychiatry.blogspot.co.uk/2011/01/chronotherapeutics-for-affective.html

"In general, interventions that lead to sleep phase advance (waking up early and going to sleep early) have an antidepressant effect, and sleep phase delay (going to sleep later and waking up later) will have a depressant (or anti-manic) effect."

I'm afraid I don't have an answer to offer, John, though diet is always my first thought. I do want to say how jealous I am of the long sleep, however. I am still struggling with sleep issues. Good luck.
