Wearing a helmet is essential for safety in various activities, such as cycling, skateboarding, and riding motorcycles. Helmets are designed to protect the head from injuries during falls or collisions. They absorb impact energy, reducing the risk of serious head trauma. Many countries have laws requiring helmet use for specific activities, especially for children. Proper fit and wearing a helmet correctly are crucial for maximum protection. Regularly checking for damage and replacing helmets after significant impacts can help ensure continued safety while engaging in sports or recreational activities.
