There are two ways you can receive energy from your environment: One is molecules bumping against you. That's the air. The other is radiative energy. That's what you're feeling from the sun. When they say "Get out of the sun, out of the heat," the air is the same temperature; it's just you're exposed to sunlight.

Not everyone is going to like science as a subject.
