Does Getting Wet in Rain Cause Fever? Fact or Myth
Partly true, mostly a myth. Rainwater itself does not give you a fever, because fever comes from an infection or another illness, not from wet skin. But a long soaking can leave you cold, tired and run down, crowded dry spots during a downpour spread colds, and muddy flood water carries real germs that rain on its own does not.
Quick facts
- Verdict: Partly. Getting wet is not a cause of fever; germs are. The setting around rain (crowds, dirty water, damp feet) can raise the chance of trouble.
- What is true: colds are caused by viruses that spread between people, and floodwater and long damp skin can bring skin and foot problems.
- What to do instead: get out of wet clothes soon, dry between the toes, warm up with a normal meal or chai, and watch for fever warning signs.

It happens every monsoon. Someone gets caught on the bike without a raincoat, walks in the door dripping, and the family says the same thing in one voice: “Ab bukhar aayega.” Two days later someone does have a fever, and the belief feels proven. Let us look at what is really going on, kindly and without blaming the person who was caught in the rain.
Why does everyone believe baarish causes bukhar?
The belief is old and understandable. Fever and cold do show up in the weeks when the rains arrive, so the two events get joined in memory. If you were soaked on Monday and sneezing on Thursday, the rain is the obvious suspect. In traditional home thinking, a sudden chill is also said to “shock” the body, and grandmothers who say so are trying to protect you.
The trouble is timing. Monsoon is also the season when mosquitoes breed in standing water, when food spoils faster in humid heat, and when people crowd under shelters and into buses. Plenty of things that cause fever are more common at the same time. The rain gets the blame because it is the thing everyone can see.
What actually causes a fever after the rain?
A fever is the body’s response to something, most often an infection. A common cold is caused by a virus, and the NHS describes colds as spread between people through coughs, sneezes and shared surfaces; its page does not list wet clothes or a chill as the cause. So a drenched person with no virus in the picture does not get a cold just from being wet.
Here is where the “partly” comes in. Being soaked and shivering can make you miserable, tired and less careful for a few hours. You may skip a meal, sleep badly in damp clothes, or sit squeezed into a crowded shelter with others who are already sick. Those situations are how a virus finds you. The water was not the germ; the crowd and the shared air were.
The rain is not the germ. The crowded shelter, the dirty puddle and the damp feet are where trouble starts.
Myth: a wet head or one soaking can give you a fever
A single soaking, or going out with damp hair, is not a known way to catch an infection. If a fever follows a day or two later, it is more likely that you were already exposed to a virus, or that the fever has a separate cause such as a mosquito bite. That is why “fever after rain” should never be brushed off as just the weather: a fever is a signal to look at the whole picture. If you are curious about the hair and sock versions of this belief, we have separate checks on sleeping with wet hair and on wearing wet socks overnight.
The part that is true: dirty water and damp skin
Rain is clean when it falls. Street water is not. Water that has run over drains, rubbish and soil can carry germs, and wading through it with a cut or blister on your foot is a real way to get a skin infection or a stomach upset. The US CDC flood safety guidance says flood water may contain rubbish, advises waterproof boots and gloves for cleanup, warns people to know when they last had a tetanus shot in case of a puncture or contaminated wound, and notes that standing water can breed mosquitoes.
Skin that stays wet for hours also softens and cracks, especially between the toes. That is how fungal itching and sore, peeling skin start. This is the practical risk most people meet in a normal monsoon, far more often than anything in the lungs.
What to do after getting wet
- Change out of wet clothes soon. Take off wet socks and shoes first; feet stay damp longest.
- Dry properly. Rub a clean towel between every toe, and under the arms and groin where skin folds hold water.
- Wash off street water. If you waded through dirty water, wash legs and feet with soap and clean water, and look for cuts.
- Warm up gently. A normal hot meal, chai or warm soup is comfortable. You do not need a special potion.
- Dry the shoes. Stuff them with newspaper and leave them in an airy place; do not wear them damp again tomorrow.
- Wash hands and watch the day. If anyone around you is coughing, wash hands before eating.
After any wet walk, run a clean dry cloth between each toe, then press the cloth to the skin for a few seconds. If the cloth comes away damp, dry again and let the feet air for ten minutes before socks. Most monsoon foot trouble starts in the skin between the toes, not in the lungs, so a two minute habit does more than any hot drink.
The same idea applies to the rest of the season. If you want the full picture of what to eat and avoid when it rains, see our guide to monsoon eating rules, and for a cold that does arrive, nazla and zukam day by day shows what is normal and when to worry.
A fever after rain is not a rain problem; it needs the same attention as any fever. See a doctor the same day for fever with a rash, a severe headache, a stiff neck, pain behind the eyes with body aches during dengue season, vomiting that will not stop, yellow eyes, confusion, trouble breathing or chest pain. See a doctor if a fever lasts more than 3 days, or if you have a long term condition, are pregnant, or the sick person is a baby or small child. Do not start or stop any medicine yourself; ask a doctor or pharmacist. Cuts that were in dirty water, turning red, hot or swollen, also need to be seen.

Questions people ask about rain and fever
Does getting wet in rain cause fever?
No, rain does not directly cause a fever. Fever comes from an infection or another illness; getting wet can leave you chilled and tired, and crowds and dirty water around rain raise the chance of meeting a germ.
Baarish mein bheegne se bukhar kyun hota hai?
Usually it does not; the timing is a coincidence of season. Monsoon also brings mosquitoes, spoiled food and crowded shelters, any of which can cause a fever a day or two after you were wet.
Can rain cause a cold?
Not by itself, because colds are caused by viruses passed between people. Standing close to someone sneezing during a downpour is the more likely route.
Bhigne ke baad kya karen?
Change into dry clothes, dry between the toes and in skin folds, and wash off any street water. Then have a normal warm meal or chai and rest.
Why do I get a nazla after getting wet?
One possible reason is that you were already exposed to a cold virus, and the soaking only coincided with it. The chill may also make you notice symptoms more.
Is a fever after rain dengue?
It can be, and that is why a fever should not be blamed on the weather. Fever with severe body ache, pain behind the eyes, rash or bleeding signs needs a doctor and a test, not a home guess.
Is it dangerous to walk through floodwater?
It can be. Street and flood water may carry germs and sharp rubbish, so avoid wading where possible, wear covered shoes, and wash and check your feet afterwards.
Should I take a hot shower after getting wet?
A warm wash is fine and helps remove street dirt. It is a comfort and a cleaning step, not a way to prevent illness.
Can wet shoes and socks cause problems?
They can irritate skin and encourage fungal itching between the toes if worn damp for long. Dry shoes properly and change socks the same day.
When should a child with fever after rain see a doctor?
A baby under 3 months with any fever needs a doctor the same day. An older child needs one if the fever lasts more than 3 days, or comes with a rash, breathing trouble, a stiff neck, repeated vomiting or unusual sleepiness.
