Urban Heat Strike: Beware of Heat Stroke

Summer season and rainy season are the two seasons in the Philippines. Most likely anyone will love summer because everyone can go out to play, be merry and have a wonderful vacation, since summer is off season or vacation time for most schools. White sandy beaches and natural pools are top priority but still, one goes back to the urbanized heat in the city. What is heat stroke and how to prevent it? What makes the urban heat sizzling?

URBAN HEAT STRIKE: BEWARE OF HEAT STROKE

It’s summertime! Temperatures in Metro Manila and near districts are striking pass the mid-30s Celsius and there is no respite from the rising scorching heat. The Philippine Atmospheric Geophysical and Astronomical Service Administration (PAGASA) reported a consequent temperature of 34.5 to 36.6 in different areas in Luzon, while the Port Area in Manila, the heat was just searing with the temperature hitting 35.3 degrees Celsius. The highest temperature ever recorded in Metro Manila was 37 degrees C on April 4, 2007 at the Science Garden in Quezon City, while this year record was a sizzling 36.2 degrees C April 24, also at the same place.

If you are a residence of the Metro, just by standing under the shade, you can feel the sizzling heat on your skin and you will perspire even without moving at all. Before I continue, let me share you some facts about heat stroke.

Heat Stroke

What is heat stroke? Heat stroke is a form of hyperthermia in which the body temperature brings to a rise dramatically. It is a medical emergency that can be fatal if not properly prevented properly and cooling the victim is the key front in the treatment. The most important step to avoid heat stroke is not becoming dehydrated and keeping away from heavy physical work in humid and hot weather.

The most at risk individuals to heat strokes include, athletes, persons who work outdoors under the sun, infants, and elders often associated with lung and heart diseases, kidneys troubles or taking medications that make them susceptible to dehydration.

Some of the common signs and symptoms of heat stroke include vomiting, over-fatigue, nausea, weakness and headache, muscle cramps and dizziness.

Urban Heat

Urbanization has warped the heat balance in the metropolis, making an increase of 1 degree to 2 degrees Celsius, according to a study and reported by Nivagine Niavares, a weather specialist from PAGASA.

Nievares said that her 2010 study and findings showed that a speedy development of the city is the major cause of the suppressing heat that the 14 million urban residents have been complaining in the past few weeks.

It has a vast effect and a difference of 1 degree to 2 degrees Celsius in the temperature all over Metro Manila and neighboring area like Bulacan, as she mentioned in an interview.

Her study reveals that the whole surface of the city affects the distribution of heat. The materials and anatomy of the structures distorted the heat dispersion. Building materials like asphalt and concrete assimilate and trap the heat coming from the sun. So the urban heat felt by the residents is not just coming from the radiation of the sun but also heat emanating from buildings, roads and houses.

At mid-day, as the solar heat energy increases, these urban surfaces absorber and storage of heat convert most of this energy into a reasonable heat discharged and this adds to the increase of temperature over the urbanized zone.

This does not finish after day time but the heat is still felt even at night without the sunshine. Pollutants and toxic air block the ascension of heat from the surface to the atmosphere and causes humidity.

Rapid urbanization has also affected rainfall, wind and breeze coming from nearby Manila Bay. The first early rainfall recorded and experienced was May 1, 2012, a sudden heavy rainfall in the afternoon of the day.

The hottest temperature as recorded so far this year was recorded earlier this month at 38.4 degrees Celsius in Clark, Dau, Pampanga, a fast-growing urban city.

I would like to see Philipines one day. Have learned so much through many of your articles about this great country. Great share!

Thanks Nisha for the kind comment and interest in visiting the Philippines.

A very timely article, Ron, even for those of us living in Colorado Springs, The temperature here are supposed to be in the upper eighties all week and will not be long before they soar to the upper nineties.

A good reminder!

Heatstroke is so dangerous -  very good advice and perfect timing with summer here.

Great article, like Nisha I too would love to visit and travel through Philipines some day, there are some really interesting and beautiful spots ...

I am always glad to learn about your homeland through your well written articles.thank you.

Very important topic.  It gets really hot in some cites here in the US during the summer months,as well.  Good you listed the signs and symtoms of a heat stroke here.  Thanks for the timely reminder

Thank you so much for the valuable information.

I live near Dau and I can feel the heat, I think if you left a raw egg outside it will be cooked. I never go outside during summer because it's very hot. And even inside the house you can feel the heat, sometimes the air conditioner won't help you. More FAN in the Philippines.

Great article! Interesting that cities are heating up as the populations grow.

Dear everyone, thanks for the read, kind comments and votes.

Best thing anyone can do for the help of others in general - plant a tree!  I have planted several.

Thank for the GREAT advice Brenda.

Important information for anyone to know about the dangers from heat stroke.

important article thanks

Curiously, as hot as it gets in Miami, there have not been recent heat strokes. God help everyone that has.  The elderly and children especially need to be aware and take precautions.  Thank you for reminding us of this danger Ron.

Rapid urbanization is dangerous you are so right; Mother Nature must be preserved. Another great article and your photos are beautiful.
