Why Sunscreen Is Necessary Even On Rainy Days?

Posted by Dr.Divneet Kaur on

Who hasn't skipped sunscreen on a grey, rainy day? After all, there's no sun, so there's no risk, right? Surprisingly, that's a common misconception. In fact, applying sunscreen is just as important on rainy days as it is on sunny ones. Here's why.

Understanding UV Rays

The sun emits two types of harmful rays: UVA and UVB.

  • UVB Rays: These are the sunburn-causing rays, most intense during the summer months and midday hours. They're also the primary cause of most skin cancers.
  • UVA Rays: These rays are present all year round, from sunrise to sunset. They can penetrate clouds and glass, and are responsible for aging the skin and contributing to skin cancer.

Why Sunscreen on Rainy Days?

Here are the key reasons why you need to wear sunscreen, even when the sun isn't shining:

  • UV Rays are Always Present: Regardless of the weather, up to 80% of UV rays can penetrate cloud cover. That means on a cloudy or rainy day, your skin is still exposed to harmful UV rays.
  • UVA Rays are Persistent: These rays are constant throughout the year and the day. They penetrate deeper into the skin, leading to premature aging and increasing the risk of skin cancer.
  • Reflective Surfaces Increase Exposure: Wet surfaces increase UV radiation because they reflect the rays. So, on a rainy day, you may be exposed to more UV rays than you think.

Importance of Daily Sunscreen

Applying sunscreen daily, regardless of the weather, is your best defense against UV-induced damage. Here's why:

  • Prevents Premature Aging: Regular use of sunscreen can slow down the development of wrinkles and leathery skin.
  • Lowers Skin Cancer Risks: Sunscreen blocks harmful UV rays, significantly reducing the risk of developing skin cancer, particularly melanoma.
  • Prevents Hyperpigmentation: Daily use of sunscreen helps prevent dark spots and skin discoloration.

Making Sunscreen a Habit

No matter the weather, make sunscreen the final step in your morning skincare routine:

  1. Choose Broad Spectrum: Opt for the best sunscreen that protects against both UVA and UVB rays. Look for a high SPF (30 or above) and a high UVA rating (PA+++ or above).
  2. Apply Generously: Dermatologists recommend using about half a teaspoon of sunscreen for the face and neck.
  3. Don't Forget to Reapply: If you're outside for long periods, reapply sunscreen every two hours and immediately after heavy sweating or swimming.

The Bottom Line

Sunscreen isn't just for sunny days at the beach. It's an everyday necessity, regardless of the weather. Even on rainy or cloudy days, harmful UV rays can reach your skin. Stay protected with a high-quality sunscreen like Dermabay's Broad-Spectrum SPF 50, PA++++ Sunscreen. It's lightweight, hydrating, and perfect for daily use. Remember, your skin's best friend is the sunscreen you wear come rain or shine!
