Scientists Now Know Why People Get More Colds in Winter

Breaking news! Scientists now know why people get more colds in winter! It's not just the weather.
Scientists have discovered why people get more colds during the winter months. The new research in the medical community is praised as a major breakthrough.

A study published Tuesday in the Journal of Allergy and Clinical Immunology found that cold air weakens the body’s immune response. Especially in the nose, which is one of the first sites of contact for respiratory viruses. It's also an important part of the body’s immune response.

The research found that reducing the temperature inside the nose by just 9 degrees Fahrenheit kills nearly 50% of the billions of virus and bacteria-fighting cells in the nostrils. The findings account for why the colder months of the year are referred to as flu season. Since the cold wintry air can freeze out half of your body’s natural line of immunity.
