Stress Transmitter Wakes Your Brain More Than 100 Times a Night, and It Is Perfectly Normal

You wake up. The alarm clock says 02:56.

“Oh no, it is not time to wake up yet,” you think, fearing that you will need lots of coffee to stay awake the following day.

Most people believe that a good night’s sleep should be uninterrupted. That is why it can be extremely annoying to wake up in the middle of the night when all you want to do is sleep.

New research from the University of Copenhagen shows that the stress transmitter noradrenaline causes you to wake up many times a night. But do not worry. It is all part of a normal, good night’s sleep and can even mean that you have slept well.

Noradrenaline is a stress hormone and transmitter substance, which is associated with the body’s fight or flight response. It is related to adrenaline, and levels may increase during stress, but it also helps you stay focused.

“You may think that sleep is a constant state that you are in, and then you wake up. But there is a lot more to sleep than meets the eye. We have learned that noradrenaline causes you to wake up more than 100 times a night. And that is during perfectly normal sleep,” says Assistant Professor Celia Kjærby from the Center for Translational.

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
