How to Stay Cool in Extreme Humidity: Practical Tips

Choose loose-fitting clothes that let air move around your skin, and favor lightweight fabrics over thick knits or tightly layered outfits that hold heat close to your body. Linen and lightweight cotton can feel comfortable for casual wear, while moisture-wicking athletic fabrics may be more practical when you expect to sweat heavily; in either case, a roomy fit usually matters as much as the fabric label.

Move errands, exercise, and outdoor work to cooler parts of the day when you can, and take frequent breaks in air-conditioned spaces during prolonged heat. Carry water, drink regularly, and pay attention to how you feel rather than waiting until you are intensely thirsty; if you are sweating a lot for hours, food or an appropriate electrolyte drink can also help replace what you lose.

When you start to overheat, get out of the sun, loosen or remove extra layers, and use a cool shower, damp cloth, or cool water on your skin while a fan helps move air. In extreme humidity, a fan alone may not provide enough cooling, especially in a very hot room, so move to air conditioning or another cooler location if you are not improving.

Headache, dizziness, nausea, unusual weakness, or heavy sweating are signs to pause activity and cool down promptly. Confusion, fainting, or symptoms that worsen or do not improve call for urgent medical help; our Stay Cool in Humid Heat – Summer Wardrobe Guide digital download is a wardrobe-planning resource, not a substitute for heat-safety decisions.
