Swimming, especially for extended periods, can leave your skin feeling dry and parched. This is primarily because the water washes away your skin's natural moisturizer, sebum.
Understanding Sebum's Role
Sebum is an oily substance produced by your sebaceous glands. It acts as a natural barrier, trapping moisture and keeping your skin and hair hydrated. Think of it as your body's built-in lotion.
How Swimming Affects Sebum
Long periods spent in chlorinated or even non-chlorinated water can strip away this protective sebum layer. The water essentially washes it away, leaving your skin vulnerable to dryness and irritation. This is particularly true if you swim frequently or for extended durations.
- Chlorine: Chlorine, commonly found in swimming pools, can further exacerbate the issue by drying out skin and hair.
- Exposure Time: The longer you're in the water, the more sebum is washed away, leading to increased dryness.
Solutions for Dry Skin After Swimming
While swimming is beneficial for health, mitigating the dryness is crucial. Consider these actions:
- Moisturize immediately after swimming: Apply a rich, moisturizing lotion or cream to replenish lost moisture.
- Shorten swim time: Limit the duration of your swims, especially if you notice excessive dryness.
- Shower with lukewarm water: Avoid hot showers, as they can further dry out your skin.
- Use mild soaps: Harsh soaps can strip away more sebum, intensifying dryness.
- Consider a post-swim oil: Oils can help to lock in moisture more effectively than lotions.
Reference: Long hours submerged in water can strip away the skin's sebum oil, which is your body's natural moisturizer. Sebum oil is a waxy substance released by the sebaceous glands, and it moisturizes your skin and hair. After coming out of the pool, that dry skin signals that your sebum oil has been flushed away.
