Night sweats can happen for a number of reasons, and many of them aren’t too serious, such as being too hot or hormonal fluctuations. In some cases, regular episodes of night sweating could indicate a serious medical condition.
It’s not uncommon to sweat at night. You may sweat a little or a lot, depending on how many blankets you sleep with, how warm your room is, and even what you ate before bed.
But if you sweat enough that you regularly wake up with wet pajamas and bedding, there could be an underlying medical issue.
Read on to learn more about possible causes of night sweats, tips to relieve night sweats on your own, and when it may be a good idea to see your healthcare professional.
Your environment
Your room, mattress, and pajamas could all influence whether you sweat during the night. Your bed may be adorned with several cozy blankets that cause overheating. Similarly, your pajamas could be too heavy, or your mattress may not be breathable. Adjusting the environment may help alleviate your night sweats.
Your nighttime routine
External factors beyond your sleeping environment may impact night sweats. These include: •alcohol use at night •eating spicy foods at dinner or as a late-night snack •exercising before sleep Avoid these behaviors before bedtime to see if your night sweats decrease.
Stress and anxiety
Anxiety and stress are mental health issues, but they often involve physical symptoms, too. Increased sweating is one common physical sign associated with these conditions. If your night sweats are happening because of anxiety or stress, you might also: •have feelings of worry, dread, and fear that keep coming back •find it hard to think about anything besides these feelings •have sleep issues or unpleasant dreams •have stomach and digestive trouble •have unexplained aches, pains, or muscle tension •feel irritable or have other mood changes •feel weak, tired, or generally unwell Addressing the underlying cause of stress and anxiety, generally by working with a therapist, may help improve all of your symptoms.
If you don’t have other symptoms that might indicate something more concerning, try these tips to relieve night sweats:
•Crack a window. Sleep in a cooler room. Leave windows cracked open at night, if possible, or try using a fan.
•Change your bedding. Replace plush or heavy blankets with breathable sheets, light quilts, or even moisture-wicking sheets. It can even help to remove extra bedding and sleep under lighter layers, so you may not need to buy new sheets or blankets.
•Adjust exercise timing. Physical activity just before sleeping could contribute to increased sweating in the night.
If you only get night sweats occasionally and they don’t significantly affect your sleep quality, you probably don’t need to be too concerned. Still, you may want to mention them the next time you see your doctor.
But if you’re having trouble sleeping, regularly have night sweats, or have other symptoms that concern you, it’s best to check in with a healthcare professional.
Some potentially serious symptoms to watch for include:
•unexplained weight loss
•body aches and pains
•high fever and chills
Your doctor will use several different methods to determine the cause of frequent or disruptive night sweats. These may include:
•discussing your symptoms, health history, and medications
•going through your family history
•conducting a physical exam
•ordering laboratory or imaging tests to determine an underlying health condition
Your doctor may refer you to a specialist if they suspect an underlying health condition that requires specialized treatment.
There are many reasons you may sweat at night.
The first culprit to consider is your environment, including your clothing, bedding, and the temperature of your room. Next, examine your habits before bedtime.

- Overactive Thyroid. Sweating more and being sensitive to heat are notable symptoms of hyperthyroidism. Your thyroid gland controls your metabolism, so when it makes too much hormone, your body goes into overdrive.
- Low Blood Sugar. Do you have diabetes? While your blood glucose may be OK when you turn in, it can drop while you're asleep. Maybe you had a very active day, or exercised in the evening, or had a late dinner.
- Sleep Apnea. When you have this condition, you briefly stop breathing over and over during the night. Because your body isn't getting oxygen, it may slip into "fight or flight" mode, which triggers sweating.
