What Happens to the Intense Immune Response in Colder Temperatures?

Professor Akiko Iwasaki is an immunologist at Yale University. Her speciality is working at what happens to viruses and our immune system in colder temperatures. For example, the rhinovirus that causes common cold grows better at 33 degrees Celsius. This can allow virus to grow better within your nose. The temperature does also control the amount of moisture in the air. That's why we are susceptible to viruses during winter months.
