Introduction
If you’re reading this, there’s a good chance you’ve woken up drenched in sweat, changed your shirt for the third time today, or wondered if something else is wrong—all after finally testing negative for COVID. You’re not alone. Sweating that lingers after COVID, or even starts weeks later, is one of those symptoms nobody warned us about. Most doctors barely mention it. Most articles gloss over it. But for a lot of long haulers, it’s real, disruptive, and confusing. Here’s what we know, what we don’t, and what you can actually do about it.
Quick Take for Low-Energy Days
If you’re sweating more than usual after having COVID—whether at night, during the day, or out of nowhere—you’re not alone. This is a real, recognized symptom of long COVID, and it can happen even after you’re “recovered.” Doctors believe it may be due to your immune system, nervous system, or hormones being out of balance after the virus. Most of the time, it’s not dangerous, just disruptive and confusing. If you ever have severe symptoms like fever, chest pain, or fainting, check with your doctor—but most COVID sweating slowly improves over time.
To manage COVID sweating, focus on small, practical steps: drink water throughout the day, wear light, breathable clothing, keep your bedroom cool, and use spare towels or sheets at night. Gentle products like absorbent pads, electrolyte drinks, and cooling sprays may help. Tracking what works for you—and connecting with others who get it—can make this frustrating symptom a little easier to handle. You’re not alone, and there’s no shame in needing extra support as you recover.
What Is COVID Sweating?
“COVID sweating” refers to the excessive, unpredictable sweating that some people experience during or after a COVID infection. It might hit at night (soaking your sheets), during the day with little activity, or even when you’re just sitting still. Unlike typical “night sweats” or hot flashes, COVID-related sweating can feel relentless—and it’s not always linked to a fever. For many, it comes in waves, with good days and bad. The frustration? There’s still very little official guidance, leaving most of us to figure it out on our own [1].
Why Does Sweating Happen After COVID?
Right now, doctors are still piecing together why COVID leaves some people drenched. Here are a few theories:
- Immune System Overdrive: Your immune response can stay “switched on” long after the virus is gone, which messes with temperature control.
- Autonomic Nervous System Dysfunction: COVID can disrupt the part of your nervous system that regulates things like sweating, heart rate, and digestion. This is called dysautonomia, and it’s common in long COVID [2].
- Hormonal Changes: Some people report changes in hormones (like thyroid or cortisol) post-COVID, which might trigger sweating.
- Medications and Recovery: Some treatments for COVID or its complications may also cause or worsen sweating.
Bottom line: There isn’t a single answer—and it’s not “all in your head.” Sweating after COVID is a recognized post-viral symptom, even if it doesn’t get much airtime [3].
Is It Normal or a Red Flag?
Most post-COVID sweating isn’t dangerous by itself. But sometimes, it can point to something more serious—especially if you have other symptoms (see “Red Flags” below). If in doubt, talk to your doctor, and trust your gut.
Common Triggers and Patterns
Many people with long COVID notice that sweating gets worse:
- At night (night sweats)
- During stressful moments or anxiety spikes
- After minimal activity (even mild exercise)
- When eating (some experience “gustatory sweating”)
- During temperature changes (moving from cool to warm spaces)
You’re not imagining it—these patterns are common, even if they seem random.
When Should You Be Concerned? (Red Flags)
Most cases of COVID sweating aren’t emergencies. But reach out to a healthcare provider if you notice:
- Unexplained fever that doesn’t go away
- Severe chills or rigors
- Drenching sweats with chest pain, shortness of breath, or palpitations
- Confusion, fainting, or severe weakness
- Signs of infection (like red, swollen skin or new rashes)
When in doubt, get checked. It’s always better to be safe.
How to Manage COVID Sweating Day-to-Day
Self-Care at Home
Here are some real-world tips from people who’ve been there:
- Stay hydrated: Sweating can quickly lead to dehydration—sip water throughout the day.
- Dress in layers: Lightweight, breathable fabrics (like cotton or bamboo) help wick away sweat.
- Keep your space cool: Use a fan, open windows, use air conditioning (HEPA air filters a plus) or try cooling towels.
- Shower or wipe down with baby wipes: Quick rinses and wipe downs can reduce skin irritation and discomfort.
- Change bedding frequently: Have spare sheets handy for nighttime sweats. Towels and spare night-wear nearby for quick fixes.
Remedies and Aids
While there’s no magic fix, some find relief with:
- Electrolyte supplements: Help replace lost minerals. Long Covid may require extra hydration—if you are sweating, you may need more than the recommended 80-120 oz per day. Consult your doctor.
- Waterproof base sheet: Keep your sleep space hygenic by avoiding repeat deep saturation. Look for soft, natural feeling base sheets that don't sound like parchment paper when you move!
- Cooling gels or sprays: Soothe skin after heavy sweating.
- Test for POTS and MCAS: Have your doctor test you for these conditions which could be contributing to your sweating. Supportive medications may be available to you.
- Review your existing medications: Do a comprehensive review with your doctor and pharmacist. Write down everything you take and share it before your appointment.
Remember—track what helps, leave what doesn’t. Everyone’s post-COVID journey is different, but you’re not stuck without options. Keep experimenting and don't give up! Improvements are slow but do happen.
Real Stories from the Community
“After COVID, I’d wake up at 3 a.m. just soaked. I started keeping a towel by the bed and a spare shirt. It’s not perfect, but at least I know I’m not alone.”
— Jess, Long COVID community member
“The sweating comes and goes. Some weeks, nothing. Others, it’s back. It’s frustrating, but hearing others have it too makes it easier.”
— Mark, Long hauler
FAQs about COVID Sweating
Q: Is night sweating after COVID normal?
A: Yes, many long haulers report night sweats—even months after infection. It doesn’t always mean something serious, but talk to your doctor if you’re worried.
Q: How long does COVID sweating last?
A: It varies. Some improve within weeks; others deal with it for months. There’s no set timeline, but most people see gradual improvement.
Q: Does sweating mean I’m still contagious?
A: No. Sweating alone isn’t a sign you’re infectious. If you’re past the isolation window and don’t have a fever, you’re not likely spreading the virus [4].
