UK heatwave advice as expert reveals how you can stop sweating during sleep

An expert has revealed why you sweat during sleep and how you can stop it. With yet another heatwave on its way this week, many of us will be prevented from having a good night's sleep because of the soaring temperatures.

The UK heatwave will make it difficult for many of us to sleep at night. Sleep expert Ashley Hainsworth fromBed Kingdom has explained why you sweat during sleep and how to prevent and treat it. Sweating during sleep mainly happens for two reasons. The first is your environment: heavy blankets and warm pyjamas can lead to heat being unable to escape, and you overheating. Another reason is underlying medical issues. TheMayo Clinic says many things can contribute to night sweats, including hormone disorders, sleep apnea, anxiety and viral infections.

The ideal temperature for sleep is between 15C and 20C. To cool down your bed, Ashley recommends adding a cooling mattress topper or switching to lighter and more breathable bedding with moisture-wicking material.

If this is not cool enough, you can place a cool pack under your pillow to lower your body temperature and stop the sweating.

Windows and doors can be kept shut during the day to keep rooms cool. Once temperatures have dropped outside, reopen windows and doors and turn fans on to create a cool breeze.

Ashley also suggested avoiding eating a large meal at least two to three hours before sleeping. This means your digestive system won't be working after you fall asleep, allowing your body to rest more.

Avoiding spicy foods and caffeine at night can also be a great way to beat the night-time sweats. Caffeine is a stimulant and can increase your heart rate, leading to a rise in blood pressure, which can activate sweat glands.

Ashley added that if your night sweats get to the point that you begin to experience daytime fatigue as a result of lost sleep, it's time to see a doctor.

If you have been sweating consistently for two weeks or more with no signs of it getting better, you should consider seeking professional help.

Stress can also play a factor. Whether it is due to nightmares or general anxiety, stress is a hormonal issue which can lead to sweating. Activities such as yoga and meditation before bedtime are a great way to reduce stress. However, if stress persists, seek professional help.
