The Department of Health has cautioned the public against heat exhaustion now that summer is officially here in the Philippines.

According to Sam Nielsen’s report on DZBB Super Radyo, heat exhaustion occurs when exposed to high temperatures and is usually accompanied by dehydration.

Some symptoms to look out for include dark-colored urine, confusion, dizziness, fatigue, headache, muscle cramps, nausea, vomiting, pale skin, excessive sweating, and rapid heartbeat.

Left untreated, heat exhaustion may progress to heat stroke, which in turn can damage the brain and other parts of the body and cause death.

To prevent heat exhaustion, drink lots of water, go to a cool place, rest, stop any activity, and ask for emergency help if needed.
