Sun and skin: How can you protect yourself effectively?

The sun is a source of life; it provides us with warmth and light. However, excessive and unprotected exposure can have harmful effects on our skin. The ultraviolet (UV) rays emitted by the sun are responsible for many skin problems, ranging from simple sunburn to premature skin aging, as well as an increased risk of skin cancer.

Why should we protect ourselves from the sun?

• Sunburn: This is the most visible sign of damage caused by UV rays. Red and painful, it can leave permanent scars and increase the risk of developing skin cancer.
• Skin aging: UV rays break down elastin and collagen fibers, which are responsible for the skin’s firmness and elasticity. They are the cause of wrinkles, dark spots, and sagging skin.
• Skin cancers: Melanoma, basal cell carcinoma, and squamous cell carcinoma are the main types of skin cancer associated with excessive sun exposure.

How can you protect yourself effectively?

• Limit exposure:
  • The hottest hours of the day: Avoid sun exposure between noon and 4 p.m., when the sun’s rays are strongest.
  • Shade: Choose shaded areas for your outdoor activities.
• Cover yourself:
  • Clothing: Wear light, loose-fitting, light-colored clothing. A wide-brimmed hat and UV-protective sunglasses are also essential.
• Sunscreens:
  • Choosing the right SPF: Opt for a broad-spectrum sunscreen (UVA and UVB) with a sun protection factor (SPF) suited to your skin type and the intensity of the sun. 
  • Apply generously: Apply sunscreen 30 minutes before sun exposure and reapply every 2 hours, and after swimming or physical activity.
• Other precautions:
  • Children: Take special care to protect children’s skin, which is more sensitive.
