Step-by-step explanation:
Whenever you’re going to be outside for a long time, it's advisable to wear sunscreen, carry an umbrella, and stay hydrated. These precautions help you to prevent skin damage and reduce the risk of skin cancer. Choose a sunscreen with a sun protection factor (SPF) of 30 or higher and that offers broad-spectrum protection against both UVA and UVB rays. Remember to reapply your sunscreen every two hours, especially after sweating or swimming. Carrying an umbrella can provide shade and further reduce UV exposure. Hydration is essential, as it helps your body with evaporative cooling and maintains bodily functions during outdoor activities.
Additionally, consider wearing sun protective clothing that has a UPF rating, which provides additional protection against harmful solar wavelengths, known as UVB, ranging between 280-320 nm. This comprehensive approach to protecting yourself from the sun will aid in preventing immediate skin damage and safeguard your long-term health.
