Dear MEL Topic Readers,
Summers could become 'too hot for humans'
As global warming progresses, winter is
getting warmer and summer is getting hotter. In some regions, the daytime
temperatures reach 40 degrees in Celsius, dangerously too hot to work outside.
Indeed, one study suggests that over one billion people could suffer heat stress
by the end of the century if temperatures kept rising by climate change. But is the temperature the only index that suffers people’s health the most? In fact, a
place at a temperature of 40 degrees under the shade in an extremely dry place like the desert is much more livable than that of 30 degrees under the direct sun in a
humid place like South Asia. Then what do we need to know?
The Wet Bulb Globe Temperature (WBGT)
measures that take not only heat but also humidity and other factors to give a
more realistic description of the conditions, such as wind speed, sun angle, and
cloud cover. The WBGT of below 30C is considered comfortable to the safe zone but
over 30C could cause dehydration and heat stress. It sounds a little
complicated to measure the conditions in your work or living environment but what
you need to do is simple. Drink enough water, get sweat, and avoid being baked
by the sun.
Enjoy reading the article and learn what you
need to do to avoid this dangerous health condition before midsummer (In the
northern hemisphere).
