Heat Stroke vs. Heat Stress: Understanding the Difference for Safe Travel

The Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) recognizes two main seasons in the Philippines (January 2022 update): the wet season (tag-ulan) and the dry season (tag-init). These seasons are influenced by the country’s location near the equator and the surrounding bodies of water, particularly the Pacific Ocean.

Months vary slightly depending on the specific climate zone within the Philippines,

  1. Dry Season (Tag-init):
    • This season typically spans from November to April.
    • During these months, the weather is generally characterized by hot and dry conditions, with minimal rainfall. This is considered the summer season in the Philippines, with temperatures often peaking in March and April.
  2. Wet Season (Tag-ulan):
    • The wet season typically extends from May to October.
    • This period is characterized by frequent rainfall, high humidity, and occasional typhoons or tropical cyclones. The peak of the typhoon season usually occurs from July to September.
  3. Transition Months:
    • The transitional periods between the wet and dry seasons, and vice versa, occur during May and October.
    • During these months, the weather can be unpredictable, with alternating periods of rain and sunshine as the seasons shift.

Note: Climate patterns can vary from year to year due to factors such as El Niño and La Niña events, which can influence rainfall patterns and temperatures in the Philippines. Additionally, local geography and topography can also affect weather patterns within different regions of the country. For the most accurate and up-to-date weather forecasts, it’s recommended to consult official sources like PAGASA.

THINGS TO KNOW IN THE SUMMER SEASON

Heat Stroke vs Heat Stress

Heat stroke and heat stress are related conditions caused by exposure to high temperatures,

Heat Stress

Also known as heat exhaustion, is the body’s response to excessive heat exposure. It occurs when the body is unable to cool itself properly, leading to symptoms such as heavy sweating, weakness, dizziness, nausea, headache, and rapid heartbeat. Heat stress can typically be managed by moving to a cooler environment, rehydrating with water or electrolyte solutions, and resting in a cool place.

Heat stroke

More severe condition and is considered a medical emergency. It occurs when the body’s temperature regulation system fails, and the body’s core temperature rises to dangerous levels (usually above 104°F or 40°C). Heat stroke symptoms include hot, dry skin (lack of sweating), confusion, disorientation, rapid heartbeat, unconsciousness, and even seizures. If left untreated, heat stroke can lead to organ damage, coma, and death. Heat stroke requires immediate medical attention. Treatment involves cooling the body rapidly, usually through techniques such as immersion in cold water or applying cold packs, along with supportive care.

Guidelines to avoid heat stress and prevent it from escalating into heat stroke

Stay Hydrated

Drink plenty of fluids, particularly water, throughout the day, even if you’re not feeling thirsty. Avoid beverages that contain caffeine, alcohol, or large amounts of sugar, as they can cause dehydration.

Stay Cool

Try to stay in air-conditioned environments as much as possible during hot weather. If you don’t have air conditioning at home, spend time in air-conditioned public places like malls, libraries, or community centers.

Wear Appropriate Clothing

Wear lightweight, light-colored, loose-fitting clothing to help your body stay cool. Also, wear a wide-brimmed hat and sunglasses to protect yourself from the sun’s rays.

Limit Outdoor Activity

If possible, limit outdoor activities to the cooler parts of the day, such as early morning or evening. If you need to be outside during the heat of the day, take frequent breaks in the shade or indoors.

Take Cool Showers or Baths

Taking a cool shower or bath can help lower your body temperature and provide relief from the heat.

Know the Signs of Heat Stress

Be aware of the symptoms of heat stress, such as heavy sweating, weakness, dizziness, nausea, headache, and rapid heartbeat. If you or someone else is experiencing these symptoms, it’s important to take action to cool down and rehydrate.

Check on Vulnerable Individuals

Keep an eye on elderly relatives, neighbors, and others who may be more vulnerable to heat-related illnesses. Offer assistance or check in on them during hot weather to ensure they’re staying cool and hydrated.

Avoid Hot Vehicles

Never leave children, pets, or anyone else in a parked car, even for a short period of time. Temperatures inside a parked car can quickly reach dangerous levels, leading to heat stroke and death.

By following these guidelines, you can reduce your risk of heat stress and prevent it from progressing to heat stroke during hot weather.
