Why do you sweat more when you exercise?

On an average day (without exercising) most people will sweat 700ml – that’s about a gym beaker full. The general rule is: The more you move, the more you sweat. When you’re exercising, it may be possible to lose around 6.5 g of salt per hour through sweating.[1] Staying hydrated, well fueled and protected from sweat and odor will help you smash your next workout.

When it comes to sweating, it’s all about balance

Most of the time, your body is in a state of heat balance – the heat entering or heat that is generated by your body is about the same as the heat leaving it. However, when you exercise, your heat balance changes and youget hot. In order to get things back on track, your body works harder to cool you downby sweating more. The evaporation of sweat from all over your body is what rebalances everything and cools us down.

Why do different parts of your body produce different amounts of sweat

The more exercise you do, the more you sweat, over your whole body and in your underarms. It may not feel like it, but when you first start exercising, your forehead and shoulder blades sweat first. The act of exercising alone (without any external heat changes) can be enough to stimulate profuse sweating.[2] Even after exercise, you continue to sweat. This happens until your internal body temperature returns to normal.[3]

How can I stop sweating a lot during exercise?

A high-performance antiperspirant deodorant will make all the difference. Spray Sure 72H Nonstop Protection and get ready to conquer your next workout.

Some simple lifestyle changes can also help. Choosing to wear loose, breathable clothing made from natural fibers, using gentle soap or body wash, taking cool showers and carrying spare pairs of socks and wearing non-plastic shoes can all make a big difference.

Not everyone sweats the same

Everyone has different levels of sweating, which is why we’ve created a new tool to help everyone understand how to measure sweat. SweatSense was developed by our Science and Technology team in collaboration with the University of Warwick. We now have an exclusive, patented tool to give us a clear measurement of sweat. It’s the first of its kind. A simple, visual way of showing how much our new product protects against sweat and odor compared to regular antiperspirants. It only reacts to sweat, not water – the sensor is applied to the underarm for five seconds to get results. The more the paper sensor turns red, the more sweat there is, but our 72HR Nonstop Protection antiperspirant has you covered – it has been tested to the limit and then tested again. Sure, it won’t let you down.

Sure is pushing the limits of sweat protection

When it comes to excessive sweating, knowledge is power, and we’ll keep innovating to keep people moving with confidence.
