As summer temperatures rise, it is important to be aware of the potential risks of extreme heat on the body. While heat affects everyone, certain individuals, such as older people and babies, may be more vulnerable to serious harm. 

When the body becomes overheated, blood vessels dilate, leading to lower blood pressure and increased heart rate. This can result in symptoms like heat rash, swollen feet, dizziness, nausea, fainting, confusion, muscle cramps, headaches, and fatigue. In severe cases, heat exhaustion can occur, potentially leading to heart attacks if blood pressure drops too low.

Our bodies naturally strive to maintain a core temperature of about 37C, regardless of external conditions. As temperatures rise, the body works harder to cool down by opening blood vessels near the skin and sweating to release heat. 

To stay safe in the heat, it is important to check on those who may struggle to keep cool, stay indoors in shaded areas, drink plenty of fluids, avoid physical exertion during the hottest part of the day, and be cautious around open water. If someone exhibits signs of heat exhaustion, it is crucial to move them to a cool place, provide water, and cool their skin.

Certain individuals, such as the elderly, those with underlying health conditions, and people taking certain medications, may be at higher risk of heat-related complications. It is important for these individuals to take extra precautions to stay cool and hydrated.

While heat-related deaths do occur, the evidence suggests that most deaths happen in the early stages of a heatwave and are often related to underlying health conditions. By following safety precautions and staying aware of the risks, individuals can protect themselves and others from the potential dangers of extreme heat.
