1. Wear the right clothing
If you know that you will be sweating a lot, choose your clothing wisely. Natural fabrics like cotton and linen are more breathable than synthetic materials like polyester. Also, light colors tend to be cooler than dark colors.
2. Stay hydrated
Drinking plenty of fluids will help to keep your body temperature down. Avoid caffeine and alcohol, as they can actually make you sweat more.
3. Use antiperspirant
There are many different types of antiperspirants on the market. Some even contain aluminum chloride, which can be very effective at reducing sweating. Be sure to apply it to dry skin for best results.
4. Take a cool shower
Taking a cool shower before you go out in the heat can help to keep your body temperature down and prevent sweating.
5. Use a fan or air conditioner
If you are in a hot environment, using a fan or air conditioner can help to keep you cool and prevent sweating.
