Limit exposure to direct sunlight during these hours. In bright sunlight, prioritize sunglasses that grant protection from UVA and UVB radiation. To ensure you’re protected from sunburn, always use sunscreen with a minimum 30 SPF. This also fights the Sun’s radiation effects on the immune system. Attention! UV strength is notably upped by the reflection of sand and water.
