Night Sweats: The Hot Topic

If you sweat during the night, you’re not alone—most people do. What are the two biggest culprits? Your bedroom and the sheets you’re sleeping on.

What Are Night Sweats?

Night sweats are episodes of excessive sweating that occur during sleep. They can be severe enough to soak your bedclothes and bed sheets, and may even wake you up. Night sweats are a common symptom of menopause, but they can also be caused by other conditions, such as anxiety, infections, and certain medications.[3]

If you regularly wake up with soaking wet sheets, you should consult your physician. Please see your doctor if you: [4]

  • have night sweats regularly that wake you up or worry you.
  • have a very high temperature (or feel hot and shivery), a cough, or diarrhoea.
  • have night sweats and are losing weight for no apparent reason.
  • you notice your sweats have a noticeable colour to them.
  • have any questions or concerns regarding your sleep health.

    The Science Behind Night Sweats

    When you sleep, your body temperature naturally drops. However, if your body temperature drops too low, your body will release hormones to warm you up, which can cause you to shiver. In some people, the body's natural thermostat becomes overactive and releases too much heat, which can lead to night sweats.[5]

    The most common causes behind night sweats can be: [3]

    • Menopause symptoms (“hot flashes”)
    • Anxiety
    • Hyperthyroidism
    • Diabetes
    • Hormonal issues
    • Neurological conditions
    • Certain sleep disorders
    • Obesity
    • Depression
    • Infections
    • Dietary triggers
    • Medicines (some antidepressants, steroids, and painkillers)
    • Alcohol or drug use
    • Hyperhidrosis (a condition that makes you sweat too much all the time)
    • The temperature in your bedroom is too high (the ideal sleeping temperature is approximately 18.3 °C).  
    • Your bed sheets retain heat and moisture, and can’t regulate your body temperature.

      • Both men and women may experience night sweats for many of the same reasons, although they are more common in women than in men.
      • Night sweats are most common during menopause, but they can start years before menopause begins.
      • There are treatments available to help reduce night sweats, such as cognitive behavioural therapy, medications, emotional support systems, and so much more.

        Still Sweating? You Need Better Bed Sheets!

        Your old, traditional bed sheets can trap heat and moisture, which might be leading to your night sweats. This is especially true if your sheets are made of cotton, which is incredibly stuffy and not the best when it comes to breathability or wicking away moisture.

        You need bed sheets made from moisture-wicking materials, like the coveted bamboo viscose, which can help keep you cool and dry at night. Don’t forget that for the perfect sleep oasis your bedroom temperature should be in the sweet spot of about 18.3 degrees Celsius.

        Take a look at our favourite bamboo viscose sheets for sweaty sleepers:

        Why do we love bamboo so much? It all comes down to Cosy House’s three Cs—Care, Comfort, and Cost:

        • Care: We care about our planet. Bamboo is one of the fastest-growing renewable sources on the planet and uses less water than cotton. And, unlike cotton yield, bamboo plants don’t need too much space to produce a large crop. Bamboo plants also make 35% more oxygen than a hardwood forest, and with their extensive root systems, they help fight back against soil erosion to boot. [1,2]
        • Comfort: We care about what’s going into your home. Viscose derived from bamboo is lightweight, breathable, and feathery-soft. Not to mention that sheets made from bamboo viscose are safe for sensitive skin and noses because they can naturally ward off common household non-living allergens!
        • Cost: We care about you. Bamboo viscose is cheaper than cotton—they give you higher quality for less money than the higher-priced alternatives (ahem … cotton). 

        Ultimately, the best bed sheet for you will depend on your individual preferences. If you need some more bedding inspiration, look no further than right here. Day or night, hot or cold—-our dreamy collection of bed sheets is just what you need for your best sleep.
