Here are some tips to help reduce sweating while riding a bicycle on those hot summer days.
Ride in the early mornings. The temperatures are always cooler in the early mornings around dawn than they are at dusk or even late night.
Choose an easy route. Try to find a bicycle route that is shaded with flat terrain or no steep hills, and as few stops as possible. Once you stop you will no longer be cooled by the wind and begin sweating a lot.
Keep your body temperature down. Take a luke warm or cool shower using antibacterial soaps before you leave to cool you down and wash away body odors. Drink plenty of water. Do not drink hot coffee or eat spicy foods. Wear a bike helmet with plenty of vent holes.
Wear breathable light-colored clothing. Clothing that wicks away sweat can help cool you down too as it evaporates, but this is generally not as effective in humid climates. Synthetic materials like polyester/nylon, bicycle jerseys, arm coolers etc. dry much faster than cotton, but cotton is also very breathable and once wet the wind will cool you down.
One trick to keep your body cool is spraying the back of a cotton shirt with water (squeeze out the excess so it doesn’t drip), and then the wind will keep you cooler. Another trick is filling a sock with ice and wrapping it around your neck. Each of these ideas is only temporary of course, but offer a refreshing feeling at least on the hottest days.
Protect your body from the sun. Wear sweat resistant sunscreen, but not sweat proof sunscreen used for swimming because it can clog your skin pores. Alternatively consider wearing UPF rated clothing with long sleeves or arm coolers. Consider not wearing a rain jacket in warmer temperatures because you will just get sweaty and smelly.
Cool down before finishing your ride. After any physical activity your body tends to take 5 to 10 minutes to catch up and stop sweating. Use a towel and/or wipes to clean up afterward. Having a change of clothes at work is probably the best idea on very hot days.
Store your sweaty clothes somewhere they can dry out – either in a bag with vent holes or in front of a fan. Use deodorant.
Sweating is a natural process, but if you have excessive sweating you might need to consult a doctor and/or nutritionist. Mixing baking soda with water and applying it to the problem areas as an antiperspirant is one solution.
