Acclimatization

The process by which the body gradually adjusts to changes in its environment, such as altitude or temperature, to maintain performance and reduce the risk of related illnesses.

Acute Mountain Sickness (AMS)

A condition that can occur when ascending to high altitudes too quickly, characterized by symptoms like headache, nausea, dizziness, and fatigue.

Basal Cell Cancer

A type of skin cancer that originates from the basal cells in the skin’s outer layer, often caused by prolonged exposure to UV radiation.

Conductive Heat Exchange

The transfer of heat between a body and a substance it is in contact with, such as heat loss to a cold surface or heat gain from a warm one.

Convective Heat Exchange

The transfer of heat between a body and a moving fluid (air or water) that surrounds it, which can increase heat loss from the body.

Dehydration

A condition resulting from excessive loss of fluids from the body, impairing physical performance and leading to serious health issues.

Electrolyte

Minerals in body fluids that carry an electric charge, essential for various bodily functions including nerve and muscle activity.

Evaporative Heat Loss

The process by which heat is lost through the evaporation of sweat from the skin’s surface, helping to cool the body.

Frostbite

A condition caused by the freezing of body tissues, usually in extremities, resulting in numbness, discoloration, and potential tissue damage.

Heat Cramps

Painful muscle contractions that occur during or after intense physical activity in hot environments, often due to electrolyte imbalances and dehydration.

Heat Exhaustion

A heat-related illness from prolonged exposure to high temperatures, characterized by heavy sweating, weakness, dizziness, and nausea.

Heat Rash

A skin condition that occurs when sweat ducts become blocked, leading to red, itchy bumps or blisters on the skin in hot and humid conditions.

Heat Stroke

A severe and potentially life-threatening heat-related illness occurring when the body’s core temperature rises above 104°F (40°C), leading to confusion and organ damage.

Heat Syncope

A type of fainting due to heat exposure and dehydration, resulting in temporary loss of consciousness.

High Altitude Cerebral Edema (HACE)

A severe form of altitude sickness characterized by brain swelling, leading to confusion and loss of coordination.

High Altitude Headache

A headache resulting from rapid ascent to high altitudes, often associated with acute mountain sickness symptoms.

High Altitude Pulmonary Edema (HAPE)

A serious condition where fluid accumulates in the lungs at high altitudes, causing shortness of breath and fatigue.

Hyponatremia

A condition characterized by abnormally low sodium levels in the blood, often due to excessive fluid intake without adequate electrolyte replacement.

Hypothermia

A dangerous condition where the body’s core temperature drops below 95°F (35°C) due to prolonged exposure to cold, leading to confusion and shivering.

Melanoma

A serious form of skin cancer originating in melanocytes, often associated with intense UV exposure and appearing as a new or changing mole.

Metabolic Heat Production

The heat generated by the body’s metabolic processes during physical activity, affecting body temperature regulation.

Psychrometer

An instrument used to measure humidity in the air, typically consisting of a wet-bulb and dry-bulb thermometer.

Radiant Heat Exchange

The transfer of heat between a body and its surroundings through radiation, such as heat from the sun.

Relative Humidity

The percentage of moisture in the air relative to the maximum amount of moisture the air can hold at a given temperature.

Rhabdomyolysis

A condition characterized by the breakdown of muscle tissue, releasing toxins into the bloodstream and potentially leading to kidney damage.

Sickle Cell Trait

A genetic condition where a person carries one copy of the sickle cell gene, affecting oxygen transport and increasing susceptibility to certain conditions.

Squamous Cell Cancer

A type of skin cancer originating from squamous cells in the skin's outer layer, often related to sun exposure.

Wet Bulb Globe Temperature (WBGT)

An index used to measure heat stress in direct sunlight, considering temperature, humidity, wind speed, and solar radiation.
