My body is 37°C, the outside is currently 42°C how is that i can stay cooler than the outside? I can understand our body giving off heat when the outside is cooler but not this.

You sweat. This liquid on your skin now vaporize, this effect needs energy and cools it’s surrounding, leading to you cooling down.
That’s also the reason why people think humid heat is worse than dry heat. If the air is already full with liquid your sweat won’t vaporize as easily (or not at all) which now doesn’t cool your body down.
