There’s nothing worse than lying in bed and realising your body is definitely not interested in sleeping – especially when you know you’ve got to be up early for work.

If you’re prone to lying there for hours at a time without drifting off, a doctor has shared the simple trick he uses when he can’t fall asleep.

Dr Myro Figura, a Los Angeles-based anesthesiologist and medical school educator, said in a TikTok video: “The number one thing you do not want to do is stay in bed.

“If, after 30 minutes, you can’t fall asleep, your brain is too activated and you need to change the environment. Go to another room and do something boring in a low light environment – things like knitting, reading, staring out of a window.

“You need to restart the secretion of melatonin by your pineal gland.”
