Why does sleeping too much make you wake up with a headache?
In: Chemistry
Do you drink coffee or pop? You may be suffering from caffeine withdrawal.
Okay so apparently one word answers aren’t sufficient explanations on this sub. My actual answer is “dehydrated” but apparently I have to explain that the human body requires a certain amount of water in a day to function properly and if you sleep all day, you are not drinking water. That is why you will wake up with dry mouth, especially if you sleep with your mouth open, and a headache. And most people don’t drink enough water as it is so you were probably already mildly dehydrated before you went to sleep. To that end, headaches in general are often caused by not drinking enough water. So yeah. Drink more water.
It could be you are waking up in the not ideal part of your sleep phase. You go through sleep phases which take about 90 minutes and there’s a point in that cycle where it is ideal to wake up, where your body temperature and brain activity and stuff is ideal to get up and go. But there’s also a part of the sleep phase where you’re in deeper sleep, you’re zonked out, you’re not moving around much, you’re more physically dead to the world than your other phases of sleep. You can buy a device or use an app on your phone that detects your movement while you’re sleep (you put the phone under your pillow for example, or wear a smart watch), and the app infers which part of your sleep cycle you are in, and then determines what the ideal time to wake you is within a timeframe you enter that you want to wake up.
I used to wake up with massive headaches. Found out I had sleep apnea. Might be the same for you?
