He was responding to somebody who said if cold water works, then would cold air work? He said because cold air opens your lungs to infection. And that isn't true.
Viruses can travel easier in cold air, but it isn't the cold air itself. It just means you are more likely to get sick if you are in close-quarters with people in cold weather than if you are in close-quarters in hot weather.
But cold weather itself doesn't get you sick if you are just sitting in your backyard with nobody around.
Plus, whether or not you have a jacket on in cold weather makes no difference in whether or not you get sick. So his answer was irrelevant.
