Going to bed stressed will make it near in possible for you to sleep, because the body is in a state of ‘fight or flight’.
This fight or flight mode sends a signal to your brain that it’s actually not safe for you to sleep. Quite simply, you need to stay awake to fight off any predators – real or imagined!
When this happens the body produces cortisol, a hormone that works in opposition to melatonin – a hormone that helps to regulate sleep.
In other words, high cortisol = low melatonin = a delay to sleep onset.
Not ideal if you’re a shift worker – especially on those tight turnaround shifts when sleep is at a premium!
It’s why implementing strategies to help you to relax prior to getting into bed, is absolutely key in helping you to fall asleep.
