Understanding Heat-Related Illnesses

Heat-related illnesses are a big health problem. They can affect people of all ages and in different places. Our bodies try to cool down, but very hot temperatures can be too much. This can lead to serious heat injuries. Managing heat stress is key to staying safe.

It’s important to know about heat-related illnesses. They have different signs and risks. In the U.S., over 600 people die each year from these conditions⁴. This shows how vital it is to be aware and take steps to stay healthy.

What Is Heat Stroke?

Heat stroke is the most serious heat illness. It happens when your body temperature goes over 104 degrees Fahrenheit⁵. This is a medical emergency that needs quick action.

Core body temperature reaches 104°F or higher⁴
Can affect individuals unable to adapt to heat⁴
Primarily impacts older adults, chronic illness patients, and infants⁴

What Is Heat Exhaustion?

Heat exhaustion is an early sign of heat illness. It happens when you lose too much water and salt through sweat. Symptoms include muscle cramps, headaches, dizziness, weakness, fatigue, nausea, and vomiting⁵.

Causes and Risk Factors

Several factors can lead to heat-related illnesses:

Prolonged exposure to high temperatures
Dehydration⁵
Intense physical activity in hot environments
Age vulnerabilities (children and older adults)⁴

Preventive strategies include knowing your risk, staying hydrated, and watching for heat stress signs. Drinking 2-4 extra cups of water an hour in hot weather⁴ can help avoid these illnesses.

Key Differences Between Heat Stroke and Heat Exhaustion

Knowing the key differences between heat stroke and heat exhaustion can save lives. These illnesses are similar but have big differences in severity and health risks⁶.

Severity Levels

Heat Exhaustion	Moderately elevated	Heavy sweating, weakness, dizziness	Serious but manageable
Heat Stroke	106°F or higher	Confusion, hot dry skin, possible unconsciousness	Medical emergency

Symptom Distinctions

It’s important to know the differences in symptoms to act fast. Key differences include:

Heat Exhaustion Symptoms:
- Heavy sweating
- Weakness and dizziness
- Elevated body temperature
- Decreased urine output
Heat Stroke Symptoms:
- Confusion
- Loss of consciousness
- Hot, dry skin
- Seizures
- Extremely high body temperature

Understanding these differences can help prevent serious health complications during heat exposure.
