Not wearing protective gear when skiing extremes increases the risk of injury. However, if you still decide not to wear protective gear, you can try the following methods to reduce the chance of injury: 1. **Technical training**: Make sure you have good skiing skills, including basic and advanced techniques. This can help you better control the snowboard and cope with changing terrain. 2. **Choose the right terrain**: Choose the terrain for skiing according to your own technical level, and avoid taking risks to try terrain that is beyond your ability, especially steep slopes, rocks or undeveloped areas. 3. **Familiar with the environment**: Understand the terrain, weather conditions and potential dangerous areas of the ski resort before skiing, so as to adjust the skiing route and strategy in time. 4. **Good physical fitness**: Strengthen core strength, balance and flexibility training to improve the body's ability to adapt to extreme sports. 5. **Stay focused**: Always stay highly focused during the skiing process, pay close attention to the surrounding environment, and react in time. 6. **Slide slowly**: Control the speed, especially on unfamiliar or technically demanding terrain, so that there is enough time to react and adjust. 7. **Travel with others**: Skiing with others can help you get help in time when an accident occurs, and you can also supervise and remind each other. 8. **Learn how to fall**: Learn the correct way to fall to reduce the damage to your body. For example, try to fall sideways and avoid using your hands to support the ground. Even so, the risk of extreme skiing without protective gear is still high. It is recommended to use appropriate protective gear as much as possible to ensure safety.
