How Swimming, Hiking, and Heat Impact Your Skin—And What Dermatologists Recommend

Swimming, hiking, and heat all affect your skin in different ways. Here’s a breakdown of how each activity impacts your skin, along with dermatologist-recommended strategies to protect and care for it:

---

### **1. Swimming**

**How It Affects Your Skin:**

* **Chlorinated Pools**: Chlorine strips the skin of its natural oils, leading to dryness, irritation, and sometimes eczema flare-ups.

* **Saltwater**: Less drying than chlorine, but still can dehydrate skin over time.

* **Extended Wetness**: Prolonged exposure to water can disrupt the skin barrier and lead to pruney, sensitive skin.

**Dermatologist Recommendations:**

* **Pre-swim**: Apply a barrier cream (e.g., petroleum jelly or silicone-based creams) to protect skin.

* **Post-swim**: Rinse off immediately and use a gentle, hydrating cleanser.

* **Moisturize**: Apply a fragrance-free, thick moisturizer to lock in hydration.

* **Sunscreen**: Use water-resistant, broad-spectrum SPF 30+ sunscreen before swimming outdoors.

### **2. Hiking**

**How It Affects Your Skin:**

* **UV Exposure**: Higher altitudes and direct sun exposure increase the risk of sunburn and photoaging.

* **Friction and Sweat**: Backpack straps and clothes can cause chafing or acne (especially on the back or shoulders).

* **Pollution and Allergens**: Skin may react to pollen, dust, or poison ivy.

**Dermatologist Recommendations:**

* **Sun Protection**: Apply broad-spectrum SPF 30+ sunscreen and reapply every 2 hours.

* **Protective Clothing**: Wear lightweight, moisture-wicking, UV-protective clothing.

* **Cleanse Gently**: After hiking, wash skin with a mild cleanser to remove sweat and environmental particles.

* **Barrier Repair**: Use a soothing moisturizer with ingredients like ceramides or niacinamide.

### **3. Heat (General Exposure to Hot Weather)**

**How It Affects Your Skin:**

* **Sweat Overproduction**: Can clog pores, leading to heat rash or acne.

* **Dehydration**: Skin loses moisture, becomes dull and more prone to sensitivity.

* **Increased Oil Production**: Can worsen acne and shine.

**Dermatologist Recommendations:**

* **Hydration**: Drink plenty of water and use a lightweight, hydrating moisturizer.

* **Oil Control**: Use non-comedogenic products and blotting papers as needed.

* **Exfoliate Gently**: 1–2 times a week to prevent clogged pores, but avoid over-exfoliating.

* **Cool Showers**: Avoid hot water, which can further dry out skin.

### **General Summer Skin Tips from Dermatologists:**

* **Choose the Right Sunscreen**: Broad-spectrum, SPF 30 or higher, water-resistant, and reapply every 2 hours or after swimming/sweating.

* **Avoid Peak Sun Hours**: Try to stay in the shade from 10 a.m. to 4 p.m.

* **Watch for Skin Changes**: New moles or persistent rashes should be checked by a dermatologist.

* **Post-Activity Skincare**: Always cleanse, soothe, and moisturize after outdoor activity.
