High-altitude gliding (such as paragliding, wingsuit flying, etc.) itself is a high-risk sport that relies on professional equipment and safety measures. **Not using protective equipment is extremely dangerous and undesirable behavior.**. Any attempt to abandon protective equipment during high-altitude gliding can be fatal and should never be regarded as a tried option. If the problem stems from theoretical assumptions or extreme survival scenarios (such as accidental equipment failure), the following principles may slightly reduce the risk in some cases (but safety cannot be guaranteed)： --- ###**Theoretical risk mitigation ideas (not recommended! ）** 1. **Reduce the falling speed** -Try to expand the clothes or form a “resistance surface” of the body (such as spreading your limbs and tightening your clothes) to increase air resistance to slow down the fall. But the effect is extremely limited, far less than professional gliding equipment. 2. **Adjust body posture** -Keep your body parallel to the ground, arch your back slightly, and bend your limbs slightly to cushion the impact (similar to the landing posture of skydiving), but the impact force when falling from high altitude is far beyond the limit of the human body. 3. **Select landing environment** - Try to fall on soft, angled surfaces (such as thick snowdrifts, sand dunes, and the canopy of woods) as much as possible. But in reality, it is almost impossible to accurately control the drop-off point. 4. **Use obstacle buffer** - Disperse the impact force by hitting branches, slopes and other objects, but it may cause serious trauma or fatal impact. --- ###**Facts that must be emphasized** -**Human body limit**: Even if you fall from an altitude of 30 meters (about 10 floors), the landing speed can reach about 90 kilometers per hour, and the mortality rate exceeds 90%. Gliding and falling at higher altitudes is almost impossible to survive. -**Safety of professional sports**: Legal high-altitude gliding must pass professional training and be equipped with paragliding, spare umbrellas, helmets, protective gear, altimeters and other equipment, and the weather and site conditions must be strictly evaluated. --- ###**Correct suggestion** 1. **Refuse unprotected attempts**: Any high-altitude sports must be premised on professional equipment and training. 2. **Systematic learning**: Obtain paragliding/wingsuit flight qualifications through formal institutions, and master emergency operations (such as opening spare umbrellas and adjusting flight attitudes). 3. **Abide by safety regulations**: Always check equipment, pay attention to weather changes, and avoid single-person adventures. Please always put life safety first, and do not trust dangerous behaviors such as “no equipment challenge”.
