FAST FACTS: Heat stroke

MANILA, Philippines – It’s summer once again! 

While the temperature reaches an all-time high this summer, heat stroke is still a health risk that can be fatal if not taken seriously. 

According to the Department of Health (DOH), heat stroke is “the most severe form of heat illness.” The body overheats and cannot cool down by mere sweating due to dehydration.

It does not involve any blockage in the blood flow to the brain, thus making the term “stroke” a misnomer.

DOH adds that one is at greatest risk of heat stroke during hot and humid weather if he/she is:

• engaged in physical activity
• dehydrated
• directly exposed to the sun for too long 

During the past week, heat-related deaths were recorded in Cagayan Valley as higher temperatures continued to bring scorching heat in the region. 

Here are signs of heat stroke you need to watch out for, and things you should do to keep safe.
