Raining season is here!
During the summer, southeast monsoon from the western Pacific
Ocean and southwest monsoon from the equatorial Indian Ocean blow onto the
Chinese mainland. These monsoons are the main cause of rainfall. During that
time, the amount of moisture in the air is particularly high. Basically a rainy
day coincide with a 100% level of humidity.
When the weather is humid, the temperature you’re feeling is
warmer than what it really is. Why? Basically our sweat is usually helping us
to reduce our body temperature. When the air is particularly high in humidity,
meaning a lot of water in the atmosphere, our sweat will take more time to
evaporate due to a water saturation in the air.
What
are the effects of humidity?
According
to scientists, the optimal humidity level is between 35% and 50%. Above 60%, your
body will start to feel discomfort.
Beside
feeling sticky, grumpy and having frizzy hair, which can be very uncomfortable,
you will mostly notice an excessive sweating, increased rate and depth of blood
circulation and increased respiration. Since sweating doesn’t work to cool us
down, our body will work harder to reduce our core temperature. Combined with high temperatures, humidity
can cause our body to overheat. Excessive perspiration causes a loss of
water, salt and chemicals very important to make our body works properly,
putting our health in danger.

Another
harmful effect of humidity on our health is how it can influence allergies and impact respiratory
diseases brought by biological agents such as mold and mildew. Mold, mildew and mites all prosper in environments
that are high in humidity. Some mold are very dangerous causing issues to our
respiratory system, circulation, mental faculties and more which can lead to a tragic
end.
Humidity
can be worse for asthmatics because
of mold spores that can easily thrive in a humid environment. The air is
heavier, full of mold, dust mites and fungi, it becomes more difficult to breathe
and they might have a higher chance of experiencing an asthma attack.
Your skin might also suffers from hot and
humid weather. Indeed, when your pores are not able to release sweat because
the air is already saturated, this can lead into a rash on your epidermis. People
usually develop heat rash on areas of skin that rub together: inner thighs or
under the arms. According to doctors, heat rash is rarely serious.
But
are there any benefits on health?
Actually,
the list of benefits is very short compared to the negative impacts of
humidity. Most scientists and doctors
don’t really agree on a list of benefits but high humidity seems to be a good
remedy against acne. However, it does not mean that low humidity level is
recommended. The perfect level of humidity is between 35% and 50% without
feeling any discomfort.
