Many people think that if you go out in a T shirt you would immediately get sick and you would get a cold. So it's a misconception. So the reason being, and the misconception is that you think that the cold is get. Is getting you sick, but it's not. It's a virus. So if you do get out in the cold and you get in a T shirt say that. Yeah. And you get sick afterwards, that's because you already had a virus in the body. Yeah, exactly. But when the body is shocked by the cold wind, it starts to focus on that and all the physiological reactions that we just talked about earlier is happening but then they cannot really focus on that virus. Yeah. And then it gets a little bit of a head start, that virus and it evolves faster. So it's like if you have a virus and you get a cold, that's just because you were not adapted to the cold and also the virus was there already.
