Safety measures
Prolonged sun exposure can lead to health issues such as skin diseases, cataracts, and other eye problems. UV levels are typically higher in tropical and hilly areas.

Experts recommend limiting sun exposure between 11 am and 3 pm. Staying hydrated by drinking clean water regularly, even without feeling thirsty, is advised. Protective gear like umbrellas, hats, and sunglasses can help reduce exposure. Extra care should be taken during outdoor events, ensuring adequate shade, food, and water for both people and pets. UV rays are intensified near water bodies and sandy surfaces due to reflection, increasing the risk of overexposure.
