6 reasons you’re sweating at night

You may have experienced the unpleasant feeling of waking up in the middle of the night only to find that you, your bedding and your bedclothes are drenched in sweat. The medical term for this is Nocturnal Hyperhidrosis – meaning ‘night time excessive sweating’.

‘Night sweats’ are uncomfortable, but you don’t have to suffer in silence as they can often be helped by making some simple adjustments to your sleep routine. Here are six reasons why you’re sweating at night:

1. Duvets

There could be a simple explanation for your night sweats. If you’re using a 13.5 tog duvet in August – you may just be far too warm! During summer, you can help yourself enjoy a much more comfortable night’s sleep by de-togging your duvet and opting for a thinner duvet, such as Fine Bedding Co Breathe 4.5 tog duvet or the Velfont Yeti Cooling Duvet. Read our article for all you need to know about togs.

2. Pillows

Your pillow could also be contributing to your night sweats. Some pillows help to disperse heat, allowing you to stay cool during the night. The Viscofresh Cooling Pillow is a unique cooling pillow that offers relief from night sweats, hot flushes and premenstrual overheating. It’s the perfect solution for hot sleepers and warm summer nights.

3. Bedclothes

If you’re wearing your winter pyjamas in the middle of summer, it may be time to invest in new lightweight nightwear. By sleeping in cool pyjamas, you will help regulate your temperature and stop those uncomfortable night sweats.

4. Bed sheets

Your bed sheets can also be a contributing factor to your night sweats. Cotton is breathable and can help you keep cooler than synthetic sheets, as the temperature gets warmer. The Hadar Egyptian Cotton 200 Thread Count fitted sheet will fit any bed and is designed for comfort, style and durability. Another option to consider is the Velfont Igloo Cooling Mattress Protector, which has a thermoregulating technology that transports moisture and heat away from your body.

5. Menopause

Night sweats could also be a symptom of menopause. Keep cool by avoiding hot baths or spicy food before bed. Wearing cool nightwear and choosing temperature regulating bed linen can also help you to gain a good night’s sleep. You can find out more about the menopause in our topic Menopause & Sleep.

6. Medical conditions

By adjusting your sleeping environment to suit the temperature of your bedroom, you may find it far easier to stay cool at night. However, if you are suffering from night sweats and your room is a normal temperature, then your night sweats could be a symptom of more serious disorders. Consult your doctor if you find that this is the case.
