Question: Why do i have nightmares or sleep-walk when i go to sleep with a light on?
I used to have really bad nightmare, sleepwalk, or talk in my sleep. Until just recently I didn't know why, but I've learned that if i leave a light on when i go to sleep or take a afternoon nap, this will happen. Why does this happen? Much appreciated for you help folks!

Light is bad during sleep bcos it keeps activating the so called coristol which is stress hormon. So, you can't get good sleep unless this hormon is deactivated by dark.



turn off the light
