What Are the Causes of Chafing? A Quick Guide

You finally did it. You’ve completed the bike route you’ve been aspiring to for months. It felt amazing, and you can’t wait to do it again.

But first, you’re going to have to take a few days to recover from the thigh chafing. As you sit uncomfortably, you ask yourself, “Is there any way to avoid this?”

It turns out there are ways to prevent the painful experience of chafing. First, though, you must understand the causes of chafing between legs.

So, in this guide, we’ll break down the causes. Once you identify what’s causing your skin chafing, you can figure out ways to prevent it. So, without further ado, let’s get started!

Causes of Chafing

The primary cause of thigh chafing is friction. As you may remember from seventh-grade science, friction results from two surfaces rubbing against one another.

When parts of your body experience friction for sustained periods, it can eventually lead to injury. It doesn’t matter where the friction occurs. If your foot rubs against your shoe long enough, it can eventually lead to damage.

Additional Causes of Chafing Between Legs

You may wonder, “Okay, I get the friction thing. But, why is it that it only bothers me when I exercise?”

In most cases, chafing doesn’t happen simply as a result of friction. After all, your clothes probably rub against your thighs for much of the day without any problems. Instead, chafing often happens because other factors worsen the friction.

One of the primary causes of chafing is excessive pressure and perspiration. When you sweat and move fast, it’s a recipe for chafing. For this reason, chafing often happens to people who ride bicycles or run.

You may also experience chafing if you’ve spent long periods in the ocean. As salt in the water rubs against your legs and gets trapped in your swimwear, it can cause your legs or other body parts to chafe.

Chafing can also happen when excessive heat, dryness, or cold are in play. So, you may experience worse pain when you ride your bike in the summer and winter than in spring and fall.

What Other Factors Affect Skin Chafing

As we’ve mentioned, other factors can worsen your chafing. Some of these include:

  • Sensitive skin
  • Too loose or too tight clothing
  • Long-distance exercise 
  • Fabrics that don’t wick moisture
  • Repetitive motions
  • Tight-fitting shoes
  • Sand
  • Salt residue from sweat or seawater

If you frequently find yourself doing some of these things, find ways to protect yourself. We’ll discuss this more in the following section.

How to Protect Yourself

The easiest way to prevent chafing is to create a layer of protection between your skin and the stuff rubbing against it. Depending on your activity, this could include new clothing fabrics or better-fitting attire. Learn more about preventing thigh chafing here.
