When we think about health, a myriad of practices and precautions likely come to mind—eating well, exercising regularly, and getting enough sleep.
However, one crucial habit that often gets overlooked is the consistent application of sunscreen. Dermatologists unanimously advocate for the daily use of sunscreen, and here’s why:
The Risks of UV Radiation
UVA and UVB Rays
The sun emits ultraviolet (UV) radiation in the form of UVA and UVB rays. UVA rays penetrate deep into the skin, contributing to premature aging and increasing the risk of skin cancer. On the other hand, UVB rays affect the outer layer of the skin, causing sunburn and also playing a significant role in developing skin cancer.
Cumulative Damage
UV exposure isn’t just a daily risk; it contributes to cumulative damage over a lifetime. This means that even short, frequent periods of sun exposure—such as walking to your car or sitting by a window—can add up to significant skin damage over time. Canadian Dermatology Association.
Misconceptions About When to Use Sunscreen
Cloudy Days
Many people mistakenly believe that they only need sunscreen on sunny days. However, up to 80% of UV rays can penetrate clouds. This means you’re still at risk for sun damage, even when the sun isn’t visibly shining.
Through Windows
Another common misconception is that staying indoors negates the need for sunscreen. UVA rays can penetrate glass, meaning you’re exposed even if you’re sitting near a window at home, in the office, or in a vehicle. Health Canada.
The Value of Consistency
Easy Habits
The key to effective sun protection is consistency. Establishing the habit of applying sunscreen every time you go outside simplifies your routine and ensures you’re always protected. By making sunscreen a non-negotiable part of your daily skincare regimen, you’re safeguarding your skin against long-term damage.
Daily Care
For the best protection, dermatologists recommend using a broad-spectrum sunscreen with an SPF of at least 30. Reapplication every two hours is essential, especially if you’re swimming or sweating. Complement sunscreen use with other protective measures like wearing hats, sunglasses, and protective clothing, and seeking shade during peak sun intensity hours (10 a.m. to 4 p.m.).

Recommendations from Experts
Broad-Spectrum Sunscreen
Choosing the right sunscreen is crucial. A broad-spectrum sunscreen protects against both UVA and UVB rays. Products with SPF 30 or higher are recommended for daily use.
Reapplication
No sunscreen can offer all-day protection. Reapplying every two hours, or more frequently if you’re exposed to water or sweat, ensures consistent protection.
Additional Protective Measures
Sunscreen is just one part of a comprehensive sun protection strategy. Wearing a wide-brimmed hat, UV-blocking sunglasses, and clothing designed to offer UV protection can help reduce exposure. Don’t forget to seek shade whenever possible, especially during peak UV radiation hours.
Taking Action
By incorporating these habits, you can significantly reduce the risk of sun damage and maintain healthier, younger-looking skin. Dermatologists emphasize that protecting your skin from UV radiation is one of the best investments you can make in your long-term health.

Conclusion
Going outside without sunscreen might seem trivial, but dermatologists assure us that it has far-reaching consequences. The consistent use of sunscreen is an easy and effective way to protect your skin from the harmful effects of UV radiation. Don’t leave your skin vulnerable—make sunscreen a daily habit and enjoy the outdoors safely.
