Doctor warns of heatstroke and illness risks during heatwaves

Family doctor Jurga Dūdienė advises people to take precautions against the heat, emphasizing that avoiding direct sunlight during the hottest parts of the day is paramount.

"It's best not to go out in the heat, from 11 a.m. until 5 p.m., when the sun is most active," Dūdienė explained. She recommends that children and the elderly especially should seek shade and avoid direct sun. For those who must work outdoors, wearing head coverings like hats is essential for protection, as are light-colored clothing and high SPF sunscreen.

Staying hydrated is critical, with Dūdienė recommending approximately 30 milliliters of water per kilogram of body weight daily. During hot weather and physical exertion, fluid intake should increase. She also stressed the importance of replenishing electrolytes lost through sweat, suggesting non-carbonated mineral water to maintain a balance of potassium and magnesium. Electrolyte imbalance can lead to serious health issues, particularly for older individuals, potentially causing heart rhythm disturbances.

We must replenish all the elements we sweat out, i.e., potassium, magnesium.

Dūdienė also warned against drastic temperature changes. She advises setting air conditioners to a moderate temperature, no more than a 5-degree Celsius difference from the outside temperature. For instance, if it's 30 degrees Celsius outside, the indoor temperature should be around 25 degrees Celsius. Sudden shifts, like entering a very cold car from extreme heat, can quickly trigger illnesses such as tonsillitis, with symptoms including fever and severe throat swelling.

Individuals with chronic health conditions, such as high blood pressure or kidney problems, are particularly vulnerable during heatwaves. Medications that increase fluid loss, like diuretics, can exacerbate dehydration and heatstroke. Symptoms of heatstroke can include dizziness, weakness, nausea, vomiting, diarrhea, and a rapid heartbeat, potentially leading to a body temperature of 39-40 degrees Celsius, requiring immediate medical attention.
