The first drops of rain can bring out two very different reactions at home. While children may be eager to run outside, jump in puddles and feel the rain on their faces, parents are often quick to say, ‘You’ll catch a cold,’ or ‘You’ll get a fever.’
But does getting wet really make children sick? Can playing in the rain weaken their immunity? And should parents rush them indoors the moment it starts raining?
There are plenty of beliefs around children and rain, and science draws a clearer line between genuine risks and common myths.
In a conversation with The Better India, Dr Shravan Krishna Reddy, a paediatrician, neonatologist and paediatric nutritionist who co-founded The Family Tree Hospital in Tirupati, breaks down some of the most common monsoon myths.
Here’s what he wants parents to know before they say “no” to every rainy-day adventure.
Myth 1: Playing in the rain causes a cold
Fact: Rain itself does not cause a cold.
“A common cold is caused by respiratory viruses — not by raindrops, wet clothes or cold water,” explains Dr Reddy.
So why do the two seem so closely connected? During the rainy season, children may spend more time in crowded school vehicles or poorly ventilated classrooms, where viruses can spread more easily.
A child may also already be incubating a virus when they play in the rain. If symptoms appear the following day, it is easy to blame the most recent event.

Dr Reddy says he hears this sentence almost every week during the monsoon. “The timing may be related, but rain is not the infection. Somewhere along the way, the child has picked up a virus — or another illness altogether.”
In other words, getting wet is not the same as getting infected.
Myth 2: Children should never play in the rain
Fact: Healthy children can enjoy occasional rain play — if the conditions are safe.
“A healthy child can occasionally play in light, clean rain under adult supervision,” says Dr Reddy.
Rain gives children a chance to move, play outdoors and experience nature firsthand, from the sound of raindrops to the feel of water under their feet. It can also become a happy childhood memory.
The surroundings, however, matter. Stagnant roadside puddles, open drains, construction sites, slippery terraces, flooded areas and thunderstorms are best avoided. Children should also wear footwear with a good grip.
“The benefit does not come from rain magically ‘boosting immunity’. It comes from movement, outdoor play, confidence, sensory experience and happiness,” Dr Reddy explains.
His advice is simple: “Let your child enjoy 10 sensible minutes of clean rain rather than spend childhood being frightened of weather.”
Myth 3: Getting wet weakens immunity
Fact: One rainy-day shower does not damage a child’s immune system.
“Immunity is not a battery that loses charge because a child got drenched,” says Dr Reddy.

A child may feel cold, uncomfortable, or tired after wearing wet clothes for too long. Children with asthma may also experience symptoms triggered by cold air, humidity, mould, or an existing respiratory infection. But that is different from saying rain has weakened their immunity.
According to Dr Reddy, parents should focus on the things that genuinely support immune health: adequate sleep, balanced nutrition, timely vaccinations, physical activity, clean air and avoiding tobacco smoke.
Myth 4: Fever after rain means the child needs antibiotics
Fact: Rain does not cause fever, and fever does not automatically mean antibiotics are needed.
“Getting wet does not directly generate a fever — fever is the body’s response to infection or inflammation, and rain is neither,” says Dr Reddy.
A child who develops fever after playing in the rain could have a respiratory viral infection or another illness, depending on the symptoms and local disease patterns.
The real monsoon risks are often around the rain: stagnant water, open drains, slippery surfaces, mosquitoes and electrical hazards — not the raindrops themselves.

He has seen parents arrive at the hospital having already started several medicines at home simply because their child played in the rain and then developed a fever.
“That is where unnecessary treatment begins: an antibiotic for a viral illness, a syrup for a cough that would have settled on its own, and a family convinced the rain was to blame.”
His advice? Watch the child, not just the thermometer. Notice how they are behaving between fever episodes. Are they drinking enough fluids, passing urine normally, responding to you and breathing comfortably?
Seek medical attention if the child is breathing fast or struggling to breathe, vomiting repeatedly, unusually drowsy or confused, passing much less urine, or develops abdominal pain, a rash, seizures or a fever that lasts beyond three days.
“Rain is not a diagnosis. A fever after rain deserves the same careful assessment as a fever in any other week.”
So, when should parents actually say no?
Dr Reddy says the conditions matter more than the calendar.
A gentle drizzle, clean surroundings, good visibility and a healthy child are very different from heavy rain accompanied by flooding, strong winds, thunder, lightning, open electrical wiring or overflowing drains.
“Parents do not have to choose between being careless and being excessively fearful. There is a sensible middle path.”
That middle path looks different depending on the child. A school-going child who is healthy and eager to splash around may be fine with a few supervised minutes in the rain. With a newborn, young infant or premature baby, parents need to be more cautious. The same applies when a child is already unwell, wheezing, or has certain chronic or immune-compromising conditions, Dr Reddy says.

And during a thunderstorm, the rule is simple: go indoors.
“When thunder is heard, children move indoors immediately – and outdoor activity does not resume until at least 30 minutes after the last thunder.”
What parents should really watch out for
According to Dr Reddy, many of the genuine risks of monsoon play come from the environment around the rain.
Floodwater and stagnant water can contain sewage, animal waste, chemicals and sharp objects. Mosquito breeding can increase the risk of diseases such as dengue and malaria, while contaminated water can contribute to diarrhoeal illnesses and infections.
Slippery surfaces, open drains, fallen branches, electrical hazards and fast-moving water can also pose immediate risks.
“Rain itself is not the villain. Contaminated water, unsafe surroundings and delayed recognition of illness are the real concerns.”
Ultimately, Dr Reddy believes children should be protected without being made afraid of ordinary childhood experiences. “From years of treating children and speaking with thousands of parents, I have learned that childhood needs both protection and freedom.”
A little rain can be part of childhood, with parents teaching children when it is safe to splash outside and when it is time to head indoors.
