Manila: The Department of Health (DOH) has issued a renewed warning to Filipinos regarding the health risks posed by hot weather and high heat index, particularly emphasizing the vulnerability of specific groups such as the elderly, children, and those with pre-existing health conditions.

According to Philippine News Agency, Health Secretary Teodoro Herbosa highlighted that while anyone can suffer from heat-related illnesses like dehydration, heat cramps, heat exhaustion, and heat stroke, certain populations are more susceptible. Symptoms of these conditions include dizziness, fever, numbness, fainting, and warm, reddish skin. Elderly individuals, children, and those already experiencing health issues are particularly prone to these conditions. Herbosa advised that these groups should avoid staying in hot environments.

The United States Centers for Disease Control and Prevention explains that older adults have bodies that are less efficient at regulating temperature due to factors like reduced sweating and blood flow to the skin. Additionally, their bodies take longer to adapt to sudden temperature changes. Children, on the other hand, have higher metabolisms, leading to increased heat production and quicker heat loss, making them more susceptible to dehydration.

Individuals with conditions such as diabetes, heart disease, and obesity may find it more challenging to regulate their body temperature or respond adequately to heat. Furthermore, certain medications can impair the body's ability to regulate temperature and produce sweat.

Herbosa noted that heat-related illnesses often begin with symptoms like severe thirst and cold sweats. If not addressed, these can lead to collapse. He urged people to drink water when thirsty and seek shade or air-conditioned environments if feeling weak or fatigued.

While heat-related illnesses can become emergencies, Herbosa reassured that most patients recover swiftly with timely and appropriate treatment. The public is encouraged to stay indoors between 9 a.m. and 4 p.m., hydrate regularly, wear light clothing, and utilize sunscreen, hats, umbrellas, and fans to prevent heat-related conditions.
