Why do people get sick in the winter time?

People seem to come down with a cold or the flu when the seasons change. Likewise, the influenza virus replicates and spreads most effectively when the air is cold and dry; "hence, people [tend to] get the flu in the wintertime," he said. Summer illnesses arise from a combination of several factors.

Likewise, people ask, why are there more colds and flu in winter?

Flu viruses are more stable in cold air, and low humidity also helps the virus particles remain in the air. That is because the viruses float in the air in little respiratory droplets, Dr. Palese said. When the air is humid, those droplets pick up water, grow larger and fall to the ground.

Why do you get sick in the cold?

In terms of infectious illnesses, germs make you sick, not cold weather itself. You have to come in contact with rhinoviruses to catch a cold. And you need to be infected with influenza viruses to contract the flu. Rhinoviruses peak in spring and fall, and influenza viruses peak in winter.

Can you get colds from cold weather?

According to Segal-Maurer, it isn't actually the cold weather that causes the common cold, it's what we do when it gets cold out. "When the weather turns cold," she says, "we all run indoors, where air is recycled and we're often in close quarters with other people and viruses. We all sneeze on top of each other."
