With recent technology advancements certain clothes perform better than others. Use the right fabric such as polypropylene, a moisture-wicking fabric, that have the ability to move moisture away from your skin so you don't have to carry the extra weight with you.
Do not wear underwear with the shorts as most of them made of cotton. Most shorts have an integral liner built in with increased support. Choose a fiber that instantly remove moisture from sensitive areas keeping them dry alleviating chaffing.
- On hot days, wear the least amount and the looser the better. The more skin you have exposed, the more it will help rid the body of the heat being produced. Loose clothing allows air in to help the sweat to evaporate, keeping you cool and comfortable throughout your run. In high humidity, however, it is nearly impossible to evaporate the sweat that accumulates.
- On cold days, you face the problem of having too much heat escape. The trick is to dress in layers. The air that will become trapped between the layers acts like insulation. A good rule of thumb is that you should be cool at the beginning of your run, because as you start to warm up from running, you will stay comfortable.
When your clothing absorbs sweat, it becomes grittier which in turn increases the friction against the nipples and other sensitive parts. One solution is to place band-aids over the nipples. Another prevention method is to apply a lubricant such as Vaseline. A good precautionary measure is always try wearing clothing that is made of a material that transports the sweat to the outside layer, such as polypropylene. The second most common condition facing runners is the chaffing and chapping of the inner thighs caused by the skin rubbing together. An easy fix is to wear longer shorts to cover the exposed skin. If this is not an option, applying Vaseline to the area will also work. Training will be a better experience from the start if the proper procedures are taken to avoid either of these conditions.
