cold shock
The first stage of cold water immersion is the cold shock response, which typically occurs within the first 1-3 minutes of exposure to cold water. This can cause gasping, hyperventilation, and increased heart rate due to the body's initial reaction to the cold temperature. Promptly getting control of breathing and focusing on self-rescue are crucial during this stage.

The first stage is evaporation. The water from water bodies and plants gets evaporated.
Water is taken in in first stage, evaporation. It return back in third stage.

During Stage 1 of cold water immersion, also known as initial cold shock, individuals may experience rapid gasping, hyperventilation, and an increased heart rate due to the sudden drop in body temperature. This physiological response can lead to a loss of coordination and an increased risk of drowning if the person is unable to control their breathing. Additionally, the cold shock can cause panic, making it difficult for individuals to think clearly or react appropriately in a survival situation.
cardiac arrest
During stage 4 of cold water immersion, known as the "adaptation phase," the body begins to acclimatize to the cold temperatures. This stage is characterized by physiological responses such as improved circulation and increased metabolic rate, allowing the body to manage the cold more effectively. Individuals may experience reduced shivering and a sense of increased comfort as they adapt to prolonged exposure. This stage can enhance endurance and resilience to cold conditions.
Loss of consciousness most often occurs during the initial cold shock response stage of cold water immersion, typically within the first minute. This initial response can cause rapid, uncontrollable gasping for breath, hyperventilation, and an increased heart rate, which may lead to panic and potential loss of consciousness.
