The one thing you should wear if you want to fall asleep quickly

If you spend your nights wondering how to get to sleep, tossing and turning and unable to switch your brain off, there might be a very simple solution. Yes, sleep trackers, sleep therapy, or even sleep meditation could help, but it might be worth trying this trick to ensure that you get a full eight hours.

According to new research, wearing woollen pyjamas is the secret to a good night's kip.

Australian scientists have found that when you put on a cosy pair of wool pjs, it keeps the body in the 'thermal comfort zone', resulting in a more rested sleep.

They discovered that students in their 20s who wore merino wool to bed fell asleep four minutes faster than those who didn't. Their counterparts took 15 minutes to snooze, whereas the wool wearers were dreaming within 11 minutes and got an extra seven minutes kip.

The participants aged between 65 and 70 who donned the woollen pyjamas were asleep in 12 minutes compared to the non-wool wearing individuals, who took 22 to 27 minutes to catch some z's.

The University of Sydney researcher Dr. Paul Swan said: 'Not so long ago sleeping under wool bedding was the norm, and science is now rediscovering the benefits of sleeping in wool.

'Maybe it is not a coincidence because wool regulates your body temperature far better, keeping you in what is known as 'the thermal comfort zone'.

'You therefore not only fall asleep quicker, sleep longer, but also have deeper, better quality sleep.

'Enjoying good sleep has become increasingly difficult in modern times, and so anything that helps is great for your mental and physical health.'

Time to invest in some cosy nightwear.
