Even before the onset of the Hot and Dry season, parts of the Philippines have already been experiencing hot weather conditions.

That’s why we need to learn how to protect ourselves from the heat, especially those who are at greater risk during this season. These include elderly people aged 65 and above, infants, young children, people who are overweight, with chronic diseases, with mental illness, and even healthy individuals undergoing strenuous physical activities during the hot months. They are the most vulnerable to heat-related incidents as high temperatures can affect the body’s ability to release heat and properly cool down.

HEAT EXHAUSTION
Being exposed to high temperatures and inadequate intake of water can result to heat exhaustion. Water depletion and salt depletion are two types of this illness. Although this is not as serious as heat stroke, heat exhaustion is not to be taken lightly as it may progress to heat stroke if left untreated.

Warning Signs:
• Dehydration, intense thirst
• Warm, flushed skin
• Dizziness or fainting
• Weakness or discomfort
• Anxiety
• Headache
• Fatigue

HEAT STROKE
The most serious of heat-related illnesses, heat stroke occurs when the body overheats and is unable to cool down.

This is a life-threatening emergency that may cause permanent disability or worse, death, if medical assistance is not immediately provided.

Warning Signs:
• Very high fever
• Rapid heartbeat
• Nausea and vomiting
• Convulsion
• Delirium
• Unconsciousness

HEAT CRAMPS
Individuals, who remain physically active in hot weather, engaging in activities such as exercise, sports, and extensive manual labor, are vulnerable to heat cramps. These are intermittent, involuntary muscle spasms, and are often associated with dehydration.

Most cases occur in the thigh and leg areas, the core and arm muscles during or after exerting effort in a hot environment.

Warning Sign:
• Muscle spasms that are painful, involuntary, intermittent and may be more intense that the typical muscle cramps

PRICKLY HEAT
Prickly heat or bungang araw is a skin condition characterized by tiny bumps or water blisters that appear due to the clogging of sweat glands during hot and humid weather.

Its most common locations are the forehead, upper back and chest, armpits, and groin areas.

Warning Signs:
• Prickly sensation
• Red bumps or rashes on the skin
• Mild swelling of the affected part

SUNBURN
The most obvious result of staying under the sun for too long is sunburn. It is the term used for reddish, irritated and sometimes, painful skin caused by overexposure to ultraviolet (UV) rays of the sun. It may vary from mild to severe, the extent depending on skin type, amount of exposure to the sun, and the sun’s intensity.

Warning Signs:
• Reddening of the skin
• Development of blisters
• Fever or chills
• Nausea
• Headache
• Weakness
• Itchiness
• Peeling skin

SORE EYES
Another health woe during this season is sore eyes. Also known as conjunctivitis, this is characterized by redness and inflammation of the membranes in the eyes.

It can spread through direct contact with hands contaminated with eye secretions of an infected person, or through other things contaminated with the virus. This can also be acquired by swimming in poorly chlorinated pools.

Warning Signs:
• Watery to pus-like discharge
• Redness of the eye with pain and/or itchiness
• Eyelids stuck together upon waking up

Vacation time, coupled with hot weather conditions, is perfect for different types of outdoor activities. But remember to keep cool and use common sense so you stay healthy during the hottest days of the year.

Here are important tips to prevent heat-related woes:
• Drink plenty of water and replace the salts lost through perspiration.
• Avoid intake of tea, coffee, soda and alcohol to lessen chance of dehydration.
• Schedule rigorous physical activities at the beginning or the end of the day when it’s cooler.
• Take a bath every day.
• Wear light and loose clothing.
• Limit exposure to the sun.
• Wear sunscreen with at least SPF 30 to avoid sunburn prior to going out. Reapply it during the day.
• Adjust to the environment; pace yourself and take it easy.
• Do not leave infants, children, or pets in a parked car.
• Stay up-to-date with weather reports to gauge how long you can stay out in the sun.
