How long does it take to die from hanging upside down?

The time it takes to die from hanging upside down can vary significantly depending on several factors, including the individual's health, the angle of inversion, and the duration of the position. Generally, a person might begin to experience serious physiological effects within a few minutes due to reduced blood flow to the brain and potential asphyxiation. Prolonged inversion could lead to unconsciousness and death within 10 to 20 minutes or longer, but individual responses can vary widely. It's important to note that hanging upside down is extremely dangerous and can lead to severe injury or death.
