There are many benefits to wearing a helmet while cycling, and many dangers to not wearing one. Many people may think that a bicycle is not a motorcycle or a car, just a very simple means of transportation without having to wear a helmet. But in fact, cycling is also highly risky, with a high probability of accidents. We need to wear helmets to protect our heads from being hurt by the impact of external forces.

The benefits of wearing a helmet include:

1. Reduce the risk of head injury

When a car accident occurs, the head is often the most vulnerable area. Wearing a helmet can reduce the risk of a serious blow to the head to some extent. A helmet can spread the force of a hit to the head, thus reducing the extent of head injury.

2. Improve riding safety

Wearing a helmet can improve riding safety. A helmet protects the head from trauma, but it also reduces the impact of the skull on the throat and brain stem. It also reduces the risk of facial and skull fractures to some extent, making cycling safer.

3. Avoid potential legal problems

Many deaths and serious injuries in bicycle accidents are not well compensated, and some families may not be able to afford such huge costs for financial reasons. Therefore, some countries and regions require wearing a helmet when riding a bicycle. Not wearing a helmet when required in these areas can result in a fine or suspension of a driver's license.
