Night-time sweating is a problem for many individuals. As well as being uncomfortable, it can cause disturbed sleep and create stains on bedding and mattresses. Of course, reducing and preventing sweating at night can be difficult, especially when you don’t understand the reason. To help you find out what’s causing you to perspire when you go to bed, we’ve created this guide to ten reasons why you’re sweating during sleep.

10 Reasons Why You’re Sweating During Sleep | BedGuard

Why do I sweat when I sleep?

If you’re unsure why you sweat during sleep, it’s important to find out. Doing so will allow you to address the underlying cause and prevent future sweating. Additionally, as night sweats can be caused by a variety of factors, including medical issues, it’s essential to your health that the reason is identified. Here are ten of the most common causes:

1. Hot environment

If you wake up feeling hot and a little sweaty during the night, it may be due to the temperature in your room. Studies have found that people sleep best when their bedroom is around 18 degrees Celsius (or 16 if you pile on the blankets). So, if yours is above this, consider lowering it.

2. Heavy pyjamas or bedding

Like the temperature in your room, your pyjamas and bedding can also cause you to overheat at night. To prevent night-time sweating, switch to lightweight pyjamas in a breathable fabric. Also, choose a lightweight doona and avoid flannelette sheets.

3. Menopause

The hot flashes that occur with menopause can take place at night, causing excessive sweating in bed. This is a highly common and frustrating issue for women in this stage of life. Thankfully, medication and avoiding certain triggers can help.

4. Hormone disorders

Many hormone disorders can cause sweating or flushing at night. If you suffer from an imbalance (or suspect you might) and are experiencing this symptom, speak to your doctor. They may be able to prescribe medicine or provide advice to help you find relief.

5. Hyperhidrosis

Hyperhidrosis is an excessive sweating disorder where the sufferer’s body produces more sweat than needed. According to Health Direct, a government-funded service, three in every 100 Australians suffer from hyperhidrosis. However, treatments, such as therapy, medicine, and surgery, are available.

6. Anxiety

Anxiety can trigger many physical symptoms, including night sweats. If you have anxiety and are experiencing this issue, it may be a sign your disorder isn’t under control. So, to speak to your doctor or therapist about the problem.

7. Illness, fever or infection

Illness, fever and infection can all lead to sweating at night. If you think one of these may be the cause of your night-time perspiration, it’s important to see a doctor. The symptom could indicate a more serious issue, such as flu or a bacterial infection.

8. Sleep apnea

If you find yourself waking up sweaty night after night, it’s possible you may have sleep apnea. As sleep apnea causes your oxygen levels to drop, it can induce the body’s “flight or fight” response, which in turn can cause sweating. Thankfully, once treated, most sufferers can get a good and dry night’s sleep.

9. Hypoglycemia (low blood sugar)

People with diabetes may experience hypoglycemia or low blood sugar at night. And, as excessive sweating is a common symptom of hypoglycemia, perspiration can occur. If you have experienced this issue, speak to your doctor. Also, consider setting an alarm to check your glucose levels during the night.

10. Alcohol, drugs and medication

Alcohol, drugs and certain medications can all be triggers for night sweats. If you regularly consume alcohol or drugs, consider limiting or completely restricting your use to stop sweating. However, be aware that withdrawal can also cause night sweats. As for any medication, speak to your doctor to see if there are alternatives that won’t cause perspiration.
