How does quicksand affect people?

Quicksand can trap individuals by creating a suction effect that makes it difficult to escape. When a person steps into quicksand, their weight can cause them to sink, leading to panic and struggle, which often makes the situation worse. The more one fights against it, the deeper they may sink, as the quicksand's viscosity increases with movement. Staying calm and moving slowly to wiggle free or float is typically the best approach to escape.
