“I still can’t believe that people think cold comes from cold water.” This statement from medical professional Dr Poorna Prajna on Instagram left us surprised. Unlike what is widely believed, Dr Prajna shared, “Cold doesn’t come from cold water. It comes from viruses. The temperatures make the symptoms feel worse. Science is simple, not emotional”.
To verify, we reached out to Dr Rituja Ugalmugale, a consultant in internal medicine at Wockhardt Hospitals, Mumbai Central, who said that the body does react to temperature changes, but cold itself doesn’t cause infections. “That’s where viruses come in,” said Dr Ugalmugle.
Does drinking cold water or sitting in AC actually cause a cold?
No, affirmed Dr Ugalmugle. “Viruses, mainly rhinoviruses, cause a cold. Cold water, AC, rain, or chilly environments don’t create viruses in the body. They can make existing symptoms feel worse. A dry nose or throat from cold air can increase discomfort, but it doesn’t cause the infection,” said Dr Uglamugle.
If cold temperatures don’t cause colds, why do more people get sick in winter or during the monsoon?
Viruses spread more easily when people stay indoors, sit close together, and share the same air, said Dr Uglamugle. “Cold weather also dries out the nasal lining, making it a bit easier for viruses to settle. So, temperature doesn’t cause the cold, but it creates conditions for viruses to spread faster,” described Dr Uglamugle.

Cold drinks can temporarily irritate a sensitive throat, making pain, congestion, or coughing feel more noticeable. “This is discomfort, not infection. The virus remains the real cause behind fever, body aches, or a runny nose,” said Dr Ugalmugle.
What should people focus on to avoid catching a cold?
According to the expert, hand hygiene, avoiding touching the face often, staying away from someone who is actively coughing or sneezing, and ensuring good ventilation in crowded places are key. “These simple steps help reduce virus exposure far better than avoiding cold drinks,” said Dr Ugalmugle.
Can cold weather still affect recovery?
Yes, but in a different way. “Breathing cold, dry air can tighten airways and worsen irritation, especially in people with asthma or sinus issues. Staying warm and hydrated makes the body feel more comfortable while fighting the virus,” said Dr Ugalmugle.
What to note?
Cold temperatures don’t create infections; viruses do. “Temperature only affects how the body feels during an infection. So, instead of blaming the fridge or AC, focusing on real preventive habits is what truly keeps colds away,” said Dr Ugalmugle.
