Manila, Philippines — The heat is definitely on now that the Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa) officially declares the start of the dry season.
While the warmth of the sun can be enticing for beachgoers and outdoor enthusiasts, the weather bureau also warns the public that it can also pose health risks such as heatstroke.
What is heatstroke?
The Department of Health (DOH) says “it is the most severe form of heat illness when the body overheats and cannot cool down.”
Because of dehydration or a humid environment, the body is unable to expel excess heat through sweating.
Individuals who engage in strenuous physical activity for an extended period of time in a hot environment are more likely to develop the condition.
Meanwhile, Pagasa claims that the heat felt by the body can be measured using their “heat index,” which can be found on their website.
According to the agency’s data, a person may suffer from a heatstroke when the heat index ranges from 33 to 54 degrees Celsius.
What are the causes?
According to DOH, the risk of heatstroke increases in hot and humid weather when combined with vigorous exercise, dehydration, and excessive direct sun exposure.
What are the signs/symptoms?
Watch out for the following signs of heat exhaustion including intense thirst or dehydration, weakness or discomfort, dizziness or fainting, anxiety and headache.
Heatstroke can also lead to symptoms such as very high core body temperature of 40 degrees Celsius or more, hot and dry skin, rapid heartbeat, convulsion, delirium, and unconsciousness or coma.
What are the precautions?
Pagasa and DOH advise the public to take the following precautions to avoid heatstroke during the summer season.
Here are some tips to keep in mind:
- Stay hydrated – Drink plenty of water and avoid sugary or alcoholic beverages as they can cause dehydration.
- Dress appropriately – To protect yourself from the sun, wear light-colored, loose-fitting clothing and a wide-brimmed hat.
- Plan your outdoor activities – Try to avoid strenuous outdoor activities during the hottest parts of the day and take breaks in a cool or shaded area.
- Keep an eye on others – Be on the lookout for signs of heat exhaustion or heat stroke in others, especially children, the elderly, and those suffering from chronic illnesses.
What are the emergency measures?
If someone experiences heatstroke, here are some pointers to remember:
- Move the patient to a shady spot or indoors and have the person lie down with the legs elevated. If still conscious, have them sip cool water.
- Remove clothing, apply cool water to the skin and fan them.
- Apply ice packs to the armpits, wrists, ankles, and groin.
- Bring them to a hospital immediately.
