Eat spicy like a Mexican Now this might not be a tip for everyone. But if you can handle (and enjoy) spicy food, then you’re in luck! The capsaicin in chilis tricks your brain into thinking you’re overheating, triggering your body’s cooling system. You sweat, your blood flow increases, and thus, you cool down. Plus, capsaicin releases endorphins. So you’ll not only feel cooler but also happier — maybe that’s the secret to expats’ happiness in Mexico.
