In response to the recent wave of extreme heat that has gripped Greece, the Hellenic Thoracic Society (HTS) has released a public health advisory aimed at preparing citizens for the intense temperatures expected to continue through the summer.
According to experts from the Society, high temperatures pose serious risks to human health, primarily triggering two heat-related conditions: heat exhaustion and heatstroke.
Who is Most at Risk?
The advisory highlights that certain groups are especially vulnerable during heatwaves. These include the elderly, young children, and individuals with chronic cardiovascular or respiratory diseases, such as chronic obstructive pulmonary disease (COPD).
However, the risk is not limited to these groups. Healthy young people are at risk in extreme heat, especially if they exercise outdoors, drink alcohol, skip hydration, or neglect sun protection.
From Heat Exhaustion to Heatstroke: What to Watch For
Prolonged exposure to high temperatures can lead from heat exhaustion to full-blown heatstroke—an emergency condition requiring immediate medical intervention.
Symptoms of Heat Exhaustion include:
• Profound fatigue or general discomfort
• Dizziness or fainting
• Low blood pressure
• Headache
• Muscle cramps
• Intense thirst
• Heavy sweating, possibly accompanied by cold, clammy skin
• Rapid heartbeat
If these symptoms are not treated promptly—by cooling the body, moving to a shaded area, and rehydrating—heat exhaustion can escalate to heatstroke.
Symptoms of Heatstroke include:
• Confusion, disorientation, or loss of consciousness
• A rapid and extreme rise in body temperature, often reaching 40–41°C (104–106°F)
• In some cases, the body may stop sweating despite the heat
Asthma and COPD patients are at higher risk during heatwaves. Experts urge them to follow protection guidelines, stick to daily treatments, and have clear medical instructions if symptoms like coughing or shortness of breath occur.
Children are also among the groups most susceptible to heat-related illnesses. Pediatrician Dr. Anna Pardali shares key summer safety tips for parents:
• Dress smart: Choose light, loose, and light-colored clothes that cover the skin.
• Wear hats: Always protect their heads outdoors.
• Avoid peak heat: Stay inside between 11 a.m. and 4 p.m.
• Use sunscreen: Apply high-SPF sunscreen regularly.
• Hydrate often: Offer fluids frequently, even if they’re not thirsty, and serve light meals.
• Limit intense play: Avoid strenuous outdoor games in the sun. If overheated, a cool (not cold) bath helps regulate body temperature.
