Why Does My Skin Itch At Night?

Ever find yourself asking, why does my skin itch at night? Usually out of frustration, this is a thought shared by many. If itchy skin is keeping you awake, we’ll help you to understand why that might be, and how you can stop it.

Allergies such as eczema are often worse at night, due to a combination of different factors. We’ve put together this guide to help you learn more about the causes of itching at night and, most importantly of all, how to get some relief and sleep better.

Why does my skin itch at night?

The most common cause of night-time itching is eczema. This condition causes the skin to become dry, red and itchy when it comes into contact with certain substances. While there are several different types of eczema, the most common is atopic eczema, where the skin irritation is triggered by allergens. It’s important to note that many people with atopic eczema also have other allergy-related conditions, such as hay fever or asthma, although this isn’t always the case.

The main causes of itching at night

There are several different factors that can increase the intensity of skin itching at night. These include:
  • Being too warm in bed: Leaving heating on, using a memory foam mattress and sleeping under synthetic bedding can all contribute to make your body overheat while you sleep. This in turn further irritates already itchy eczema, making it worse and causing you to stay awake.
  • Dust mite allergens: While there are many different allergens that can cause eczema, from pet hair to pollen, one of the most common triggers is dust mites. If you frequently find your eczema symptoms are worse at night, then dust mite allergens may well be the cause. This is because most bedding provides the ideal environment for dust mites to thrive – a warm, moist environment – exposing you to increased allergens while you sleep.
  • Less distractions: Children in particular can become more aware of their itchy skin at night, simply because they have less distractions to keep them occupied.

    Other causes of itching at night

    • While eczema is often the cause of skin itching at night, there are a number of other conditions that can trigger similar symptoms. These include short-term conditions such as sunburn, prickly heat and ringworm, as well as longer term conditions related to the kidneys, liver or thyroid. Both pregnancy and the menopause are also causes of itching at night. If you have not already been diagnosed with eczema, you should speak with your doctor about your night-time itching symptoms to rule out any other causes.

  • Turn central heating down or off: and keep a window open (unless pollen is trigger for you) or a fan running to manage air temperature.
  • Choose pyjamas in natural materials: This is a great natural remedy for itchy skin at night. Swap polyester sleepwear for cotton or silk alternatives that will help you stay cooler throughout the night.
  • Replace synthetic bedding with hypoallergenic alternatives: Wool has been proven to be more effective at managing temperature and absorbing moisture than either polyester or feather/down fillings. Choose a wool- filled duvet, pillow and mattress topper to improve your temperature-regulation while you sleep. Learn more about the benefits of hypoallergenic bedding and how it works.
  • Swap your memory foam mattress for a heat-regulating alternative: Natural fibers are more effective for keeping cool.
  • Keep your emollient cream to hand: It won’t make your bedroom cooler, but it will help to quickly cool and soothe night-time itching if you do wake.
  • Replace synthetic carpets with pure wool or hardwood flooring.
  • Swap synthetic bedding for wool-filled alternatives, as dust mites can’t live in the dry, cool environment created by a wool-filled duvet, pillows and mattress protector.
  • Keep feather/down or synthetic-filled cushions out of the bedroom, or replace them with wool-filled versions.
  • Choose wooden or metal blinds in place of curtains made from synthetic materials.
