A hot shower can relieve some COVID symptoms, particularly congestion and body aches, but it comes with real tradeoffs depending on how sick you are. It won’t fight the virus itself or speed your recovery. What it can do is make you more comfortable for a short window, as long as you take a few precautions.
How a Hot Shower Helps With Congestion
The main benefit of a hot shower during COVID is the steam. Warm, humid air loosens mucus in your nasal passages and sinuses, making it easier to breathe when you’re stuffed up. This is the same principle behind standing over a bowl of hot water with a towel over your head, just less targeted. A shower surrounds you with moist air, which can temporarily ease that heavy, blocked feeling in your nose and chest.
Steam inhalation has been explored as a supportive therapy for respiratory infections, including COVID. While it can help manage symptoms like congestion and throat irritation, there is no scientific evidence that steam kills the virus or shortens the course of illness. Think of it as comfort care, not treatment.
Relief for Body Aches and Fatigue
COVID often comes with significant muscle soreness and that deep, whole-body ache that makes it hard to get comfortable. Hot water increases blood flow to your muscles and helps them relax, which is why a warm shower feels so good when you’re achy. The temporary pain relief can also help you rest better afterward, and sleep is one of the most productive things your body can do while fighting an infection.
The key word is temporary. You’ll likely feel better for 30 to 60 minutes after stepping out, but the underlying inflammation driving those aches is still there. Pairing a shower with an over-the-counter pain reliever can extend that window of comfort.
Why Hot Showers and Fever Don’t Mix
If you’re running a fever, a hot shower can work against you. Your body is already struggling to regulate its temperature, and adding external heat makes that harder. A hot shower can push your core temperature higher, leaving you feeling worse, not better.
Lukewarm water is the safer choice when you have a fever. It can actually help bring your temperature down slightly while still giving you the steam benefits for congestion. If you do take a lukewarm bath, get out once the water starts to cool, since sitting in cooling water can trigger shivering, which raises your body temperature again.
The Fainting Risk Is Real
This is the part most people don’t think about. COVID is associated with drops in blood pressure and heart rate instability, a condition sometimes called postural orthostatic tachycardia. Common symptoms include dizziness, heart palpitations, and fainting, and these can worsen with bathing and hot temperatures specifically.
Hot water causes your blood vessels to dilate, which lowers blood pressure. For a healthy person, your body compensates almost instantly. But when you’re fighting COVID, especially if you’re dehydrated (which is common with fever, reduced appetite, and sweating), that compensation may not happen fast enough. The result can be lightheadedness or fainting in the shower, which creates an obvious injury risk.
If you’ve been feeling dizzy when you stand up, or if you’ve had moments of feeling faint during your illness, skip the hot shower or sit on a shower stool. Keeping the water warm rather than truly hot also reduces this risk significantly.
Practical Tips for Showering With COVID
A few adjustments can help you get the benefits without the downsides:
- Keep it short. Five to ten minutes is enough to get the steam benefit and muscle relief. Longer showers increase fatigue and the chance of feeling lightheaded, especially if you’re already short of breath.
- Use warm, not hot water. Especially if you have a fever or have noticed any dizziness. You’ll still get steam and muscle relaxation at a comfortable warm temperature.
- Drink water before you get in. Dehydration amplifies every risk, from blood pressure drops to worsening fatigue. A glass of water 15 minutes beforehand makes a noticeable difference.
- Sit down if you need to. There’s no reason to push through feeling unsteady. A plastic chair or stool in the shower is a simple safety measure, and many people recovering from COVID find it makes the experience much more manageable.
- Leave the bathroom door unlocked. If you live with someone, let them know you’re showering. Fainting in a locked bathroom is a scenario worth preventing.
When a Shower Might Not Be Worth It
If you’re experiencing significant shortness of breath, the physical effort of standing in a shower may leave you more exhausted than the relief is worth. The steam can help loosen mucus, but it doesn’t improve your body’s ability to absorb oxygen. If you’re monitoring your oxygen levels and they’ve been trending below 94%, or if you feel winded just walking to the bathroom, a hot washcloth over your face while lying in bed can give you some of the steam benefit without the exertion.
For most people with mild to moderate COVID, a warm shower once or twice a day is safe and genuinely comforting. It loosens congestion, eases aches, and can provide a small psychological boost during days that otherwise feel pretty miserable. Just keep the temperature reasonable, keep it brief, and pay attention to how your body responds.
