Sweatingis normal and one of the main ways that your body stays cool.Whether you’re doing a hard workout or tanning outside on a hot summer day, sweating is a normal, expected response to your daily activities.

But you may find yourself sweating at unexpected and relatively inactive times—like when you’re in bed trying to sleep at night.

Here’s what experts say about the causes of night sweats, including when to talk to your healthcare provider about them and how to get relief ifyou’re sweating in your sleep.

What Are Night Sweats?

What Causes Night Sweats?

Margarita Oks, MD, a pulmonologist and the associate director of the Sleep Center at Lenox Hill Hospital in New York told Verywell that sweating in your sleep is also called “night sweats.”

This nighttime sweating is defined as episodes of very heavy sweating while you’re sleeping—even to the point where the sweating soaks your clothes and bedding.

There are a few things that cause night sweats. Here’s a rundown of the most common causes of sweating at night.

Menopause

Denise Pate, MD, a board-certified physician and medical director with Medical Offices of Manhattan, told Verywell that duringmenopause, people go through major changes in their bodies’ production of hormones like estrogen and progesterone.

These hormonal changes lead many menopausal people to have changes in their body temperatures which lead to symptoms likehot flashes, excessive sweating, and night sweats.

Why You Get Hot Flashes at Night During Menopause

Medications

According to Oks, some medications have sweating as a possible side effect.

Common medications that can cause you to break out into a sweat at night include antidepressants, pain relievers,diabetesmedications, and steroids.

Infections

Pate said that severalinfections and illnesses can also cause night sweats, including HIV, fungal infections,osteomyelitis(a bone infection),endocarditis(an infection of the heart’s inner lining), andtuberculosis(a bacterial disease of the lungs).

Hyperthyroidism

In people with an overactive thyroid (hyperthyroidism), the gland makes more thyroid hormone than what the body needs.

According to Pate, when the thyroid gland is pumping out too much thyroid hormone and working too hard, it can raise the body’s temperature and metabolism, which can cause people to sweat.

Cancer

Pate said that sweating at night can be asymptom of certain types of cancersor a side effect of cancer treatments.

For example,Hodgkin’s lymphoma,non-Hodgkin’s lymphoma, andleukemiaare types of cancers that often cause night sweating.

Sleep Apnea

According to Pate, people withsleep apnea—a serious sleep disorder that causes their breathing to stop or get very shallow while they’re asleep—may have night sweats because of the extra effort that’s needed to breathe at night.

Anxiety and Stress

When you’re feeling mentally anxious, stressed, or overwhelmed, you may havephysical symptoms of anxiety, too.

For example, emotional stress can lead to an increase in your heart rate and respiration. If you are feeling emotional stress before bed, Pate said it can also causesweatingwhile you’re asleep.

Alcohol

Lifestyle behaviors like what you eat and drink before bed can also make you more likely to get night sweats.

For instance, if you have an alcoholic beverage before bedtime, Pate said your body will try to metabolize thealcohol, which can make you sweat while you sleep.

Environment

Oks said there are several things in your living space that can make you more or less likely to get sweaty at night, like thetemperature in your bedroom, the material of your pajamas, and the number of blankets on your bed.

How Common Is Sweating at Night?

Since many people do not tell their providers that they’re sweating at night, there have not been a lot of research studies on night sweating in the general population. Pate said it’s difficult to say exactly how many people experience night sweats.

However, Pate also said it’s probably not that uncommon or even unexpected—especially if the room that you’re sleeping in is too hot if you’re using too many blankets, or if you’re wearing several layers of clothing to bed.

“Night sweats are estimated to affect up to 41% of menopausal women and up to 80% of people with certain medical conditions such as tuberculosis and lymphoma,” Pate said.

When To See a Provider for Night Sweats

If you’re only getting night sweats occasionally and it’s not disrupting your sleep or life quality, it may not be a reason to worry.

But if the above adjustments don’t help and your night sweats seem to be getting worse or more frequent, it’s time to see your provider, especially if it’s affecting your ability to sleep.

“If night sweating is acute in onset (started suddenly), quickly progressive, and is associated with other symptoms then this should be discussed with a physician sooner rather than later,” said Oks. “If night sweating is associated with environmental conditions, then this is not as concerning and can be managed independently.”

Either way, seeing your provider is the first step to figuring out what’s causing them and getting relief.

What This Means For YouNight sweats can be common and are often a sign that something about your sleep environment is making you too hot—for example, your bedroom is too warm or you’re sleeping in clothes or bedding that’s not letting your body cool off.However, sweating at night can also be a symptom of an underlying health condition or even a medication side effect. If you’re having night sweats often and can’t seem to get relief, reach out to your provider.
