Why Do White Spots Appear on Skin After Working Out?
Experiencing white spots on skin after exercise might cause you a bit of worry. However, understanding why this occurs can offer peace of mind. Generally, these spots appear due to two significant reasons: blanching and sweat residue:
Blanching
During intense physical activities, certain parts of your skin might experience pressure, leading to a reduction of blood flow to that area, a process called blanching. This temporary phenomenon results in white spots which disappear once the pressure is removed and the blood flow resumes.
Sweat Residue
Sweating is a natural process while exercising. As you sweat, the liquid evaporates, leaving behind salt crystals on your skin. These salt crystals can appear as white spots on skin after exercise.
Understanding that this is a natural process can reduce any anxiety you might experience seeing them on your skin.
Medical Conditions That Can Cause White Spots on Skin After Exercise
Beyond the common occurrences of blanching and sweat residue, medical conditions might sometimes be the underlying causes of the white spots on skin after exercise. Here are a couple of them explained in detail:
Tinea Versicolor
This is a fungal infection that thrives in hot and humid environments. It is known to cause skin discoloration that becomes more noticeable when you sweat. It often appears as patches of skin that may be lighter or darker than your surrounding skin. (Source)
Pityriasis Alba
This is a mild form of eczema that mainly affects children and young adults. It manifests as dry, light-colored patches on the face, upper arms, neck, and trunk.
The exact cause is unknown, but it tends to worsen with sweating, making it more noticeable post-exercise. (Source)
How to Prevent White Spots on Skin After Exercise
Fortunately, there are several precautionary measures you can take to prevent the appearance of white spots on skin after exercise. Here, we detail the steps you can adopt:
Hydration: Drinking sufficient water can aid in reducing the salt concentration in your sweat, minimizing the chances of salt crystal formation on your skin.
Moisture-wicking clothing: These types of garments help absorb moisture from your skin, reducing the accumulation of sweat and, consequently, the risk of salt crystal formation.
