Hypothermia is generally classified into three distinct stages based on the severity of the condition and the physiological effects on the body. These stages help first aid responders and medical professionals assess the situation and determine the appropriate interventions for a person experiencing hypothermia.

The three stages include:

1. Mild Hypothermia: This occurs when the body temperature drops just below the normal range, typically between 32°C to 35°C (89.6°F to 95°F). Symptoms at this stage may include shivering, confusion, difficulty speaking, and fatigue.

2. Moderate Hypothermia: In this stage, the body temperature falls between 28°C to 32°C (82.4°F to 89.6°F). Symptoms become more pronounced, with significant impairment of motor functions and coordination, as well as increased confusion and slurred speech.

3. Severe Hypothermia: This is characterized by a body temperature lower than 28°C (82.4°F). At this stage, the risk of life-threatening complications increases significantly. Signs may include extreme confusion or unconsciousness, a weak pulse, and slow or irregular breathing.

Understanding these stages is crucial for recognizing the seriousness of hypothermia and implementing timely and appropriate first aid measures. By
