Night Sweats COVID: Causes, Symptoms, and What They Mean

Waking up drenched in sweat can be alarming, especially if you’ve recently been sick or exposed to a virus. Many people have reported night sweats COVID symptoms during infection or recovery, leading to confusion and concern.

While sweating at night isn’t always dangerous, understanding what triggers it—and when it may signal something more—can help you respond calmly and appropriately.

What Are Night Sweats?

Night sweats are episodes of excessive sweating during sleep that soak your clothes or bedsheets, even when the room temperature is cool.

They are different from normal sweating caused by:

Heavy blankets
Warm weather
Physical activity before bed

Instead, night sweats usually point to internal changes in the body, such as illness, hormonal shifts, or immune responses.

Can Night Sweats COVID Be a Symptom?

Yes, night sweats COVID has been reported as a symptom by many patients during both active infection and recovery. While it is not among the most common signs like fever or cough, it does occur often enough to be medically recognized.

For some people, night sweating appears:

Alongside fever
During the recovery phase
As part of post-viral symptoms

What Causes Night Sweats During COVID?

Several biological processes can explain why COVID may trigger sweating at night.

1. Immune System Activation

When the body fights a viral infection, it releases inflammatory chemicals. These can temporarily raise body temperature, leading to sweating—especially during rest.

2. Fever Fluctuations at Night

Body temperature naturally rises during sleep. Even low-grade fever can cause night sweats COVID patients often describe.

3. Nervous System Changes

COVID may affect the autonomic nervous system, which controls sweating, heart rate, and temperature regulation.

4. Post-Infection Adjustment

After recovery, the body may take time to normalize, leading to lingering symptoms such as fatigue and sweating.

How Long Do Night Sweats COVID Last?

There is no fixed timeline, but patterns are commonly seen:

During infection: A few days to a week
Early recovery: One to three weeks
Post-COVID cases: Symptoms may appear intermittently for longer

If sweating gradually improves, it’s usually a sign of healing. Persistent symptoms deserve attention.

Night Sweats COVID vs Night Sweats Before Period

Not all night sweating is illness-related. Hormonal changes can also cause similar symptoms.

Night sweats before period:

Occur a few days before menstruation
Are linked to estrogen changes
Usually stop once periods begin
Do not involve fever or infection symptoms

Key difference:

If sweating occurs outside your normal menstrual cycle or alongside illness symptoms, night sweats COVID may be a more likely explanation.

Chest pain
Severe fatigue
Symptoms lasting more than 3–4 weeks
