Sleep deprivation can negatively affect one’s body. Sleep loss has been shown to shorten a person’s life span and increase the risk of dangerous health complications. Those who sleep less than five hours a night is more likely to catch a cold than those who get in the full recommended amount. Verena Senn, neurobiologist and sleep expert at Emma, the sleep company spoke exclusively to Express.co.uk to give her tips on how to ensure a good night’s rest despite the sweltering heat.
“It’s common sense to think the lesser the better when you’re hot, and many Brits may even be sleeping naked – there’s been some debate whether sleeping naked is actually better for us,” said Mrs Senn.
“But when it comes to night-time clothing, it’s actually better to wear pyjamas, just as long as they are natural cotton.
“This is because cotton actually helps your skin breathe, while absorbing your sweat during the night.”
Mrs Senn suggests: “Try splashing some water or placing a cold ice-cube on your body’s different pulse points, such as your wrists or the sides of your neck, for a short period of time.
“Your body’s blood vessels will react to the cool sensation and instantly bring your core temperature down.
“However, try and avoid your feet and hands, as this can prevent you from falling asleep.
“This might sound nuts but cuddling a warm blanket or taking a hot shower or bath before bed will help your body reduce its core temperature,” suggests Mrs Senn.
“Warmth in your blood vessels in your hands and feet will dilate and help you to lose excessive body heat.
“While cold water might feel more refreshing in the short term, warm water has a better long-term effect.”
Wet wet wet
When trying to cool the body right down before slumber, Mrs Senn said: “Apply wet clothes or ice packs to your skin for an optimum cooling sensation.
“You can even try filling a hot-water bottle with cold water and placing it between your legs (for short periods) as this is where your blood flows closest to the surface of your skin and will quickly cool you off.
“Of course, it goes without saying that you should never apply an ice pack directly to your skin. Always wrap it in a cloth or towel to avoid damaging your skin.”
