In fact, recent research suggests sleep-deprived people are more likely to have suppressed immunity, potentially putting them at a greater risk of catching viruses. The catch? The more you worry about falling sick, the more likely it will mess with your kip.
“It’s a vicious cycle because if you're sleep-deprived, you're more likely to be anxious and when you’re anxious you’re more likely to not be able to sleep well." Dr Junge says.
“Take our advice and prioritise getting a good night’s sleep. Put down your phone, close your laptop and go to sleep."
Dr Junge says setting aside a "worry time" can be super to help your brain switch off at bedtime. “Use this time to think about what has been happening during the day, make plans and possible solutions. Then don’t think about these things until the next day,” she says.
Prep your body and mind for sleep an hour before you need to nod off (“listen to quiet music or do relaxation.”) Or, if it’s more your thing, daydream of your favourite holiday spot.
“If other thoughts come in, consider them for a moment and then try to gently replace them with calm thoughts,” Dr Junge adds.
So how much shut-eye do we actually need to stay fighting fit? For adults (aged 18-64), the recommendation is 7-9 hours per night.
