We spend more time indoors and have closer contact with each other, which makes it easier for the virus to spread.

Does a cold weaken your immune system?
The immune system is actually overreacting to the virus, as cold viruses don’t cause the cell destruction that influenza viruses do. 2 The discomfort you feel due to sore throat, congestion, nasal discharge, and phlegm is primarily due to the effects of the immune response, not damage from the virus.
Can you catch a cold from being out in the cold?
The only way you get sick is when you come into contact with a virus. Cold air may irritate a condition you already have, like asthma, which could make your body more receptive to a cold virus. But you still need to come in contact with the virus.

Because viruses are sensitive to temperature changes and cannot survive above normal body heat, your body uses fever to help destroy them.
Do viruses make you sick?
Viruses make us sick by killing cells or disrupting cell function. Our bodies often respond with fever (heat inactivates many viruses), the secretion of a chemical called interferon (which blocks viruses from reproducing), or by marshaling the immune system’s antibodies and other cells to target the invader.
