why it is necessary to apply sunscreen to your skin and wear sunglasses when you want sunbathe on the beach?
To keep UV rays from damaging the skin and eyes.
Applying sunscreen to your skin and wearing sunglasses while sunbathing on the beach is necessary for several important reasons.
1. Protection from harmful UV rays: Sunscreen acts as a protective barrier between your skin and the Sun's ultraviolet (UV) rays. These rays consist of UVA and UVB radiation, which can lead to sunburn, premature aging, and an increased risk of skin cancer. Sunscreen with a high sun protection factor (SPF) helps to block or absorb these harmful rays and prevent damage to your skin.
To apply sunscreen correctly:
- Choose a broad-spectrum sunscreen that protects against both UVA and UVB rays.
- Apply sunscreen generously to all exposed areas of your skin, including your face, neck, arms, legs, and any other areas that will be exposed to the sun.
- Reapply every two hours or more frequently if you perspire heavily or go swimming.
2. Preventing eye damage: Sunbathing on the beach often involves direct exposure to the bright sunlight, which can be harmful to your eyes. UV rays can cause various eye problems, including cataracts, macular degeneration, and even sunburn on the surface of your eyes (known as photokeratitis). Wearing sunglasses with proper UV protection can shield your eyes from these harmful rays and reduce the risk of eye damage.
To choose appropriate sunglasses:
- Look for sunglasses that provide 100% UV protection or are labeled as UV400, which blocks both UVA and UVB rays.
- Opt for sunglasses with larger lenses or wraparound styles, as they offer increased coverage and minimize peripheral exposure to sunlight.
- Ensure that your sunglasses fit properly and comfortably to avoid any gaps that could allow UV rays to reach your eyes.
By applying sunscreen and wearing sunglasses, you can enjoy your time in the sun while taking important measures to protect your skin and eyes from potential harm.
