Wendy Troxel, PhD, spoke to Byrdie about the science behind this idea and it's all about training your brain to realise that bed is primarily for sleep, not work, worry or stress.
"Our brains learn by association, and to sleep well, you want your brain to have a strong learned association between the bed and sleep".
The best thing you can do is stop yourself thinking about the fact you only have three hours left to alarm time by concentrating on something else.
The sleep professional recommends reading a book/magazine but make sure it's in low-light conditions so you don't wake up too much.
Having tried this before when I'm awake at 3:30a.m without any sleep, I can confirm it works just as well for insomniacs as those who are prone to waking in the early hours.
Give it a go, you might be surprised.Woman with same cancer as MAFS star shares symptoms
