Why can having a nightmare cause you to wake up drenched in sweat?
In: Biology
Sometimes nightmares are cause by being hot in bed so the sweating and nightmares may be cause by overheating!
Your brain and nervous system regulates most functions. When you’re dreaming your brain still regulates even though the stimulus it responds to may be of its own making (e.g. you can wake up feeling full of adrenaline from an action packed dream, even though there is no “action” around you – the adrenaline is still real).
Anxiety is a common source of sweating both when awake, and in dreams. All because of your brain. Further, you exacerbate that by being under covers and not doing the “Normal stuff” you’d do when sweating when awake.
