Air conditioning unnecessary in majority of global heatwave conditions
MedicalXPress / University of Sydney / The Lancet “Planetary Health” ^ | June 14, 2021 | Nathan B Morris et al

Posted on 06/14/2021 11:02:53 AM PDT by ConservativeMind

The biophysical modeling study, published in The Lancet Planetary Health, challenges outdated public health guidance that discourages fan use in temperatures higher than 35 degrees Celsius / 95 degrees Fahrenheit.

Based on human studies carried out at the University of Sydney's Thermal Ergonomics Laboratory, the researchers developed a model to determine the humidity-dependent temperature thresholds at which fans could become detrimental, providing conditions that exacerbate heat stress.

"The effectiveness of a fan depends on temperature and relative humidity and our previous human studies have shown that it is only when the air temperature is very high and humidity is extremely low that fans can be detrimental," said senior author Professor Ollie Jay…

Specifically, they propose that the simplified fan use temperature threshold of 35°C currently recommended by the WHO should be increased to 39°C for young healthy adults, 38°C for healthy adults older than 65 years, and 37°C for older adults taking anticholinergic medication.

With how governors and the current president force everyone to follow the WHO (or do worse), expect these to come to you as regulations.

So you don’t have to convert, the WHO is now being told to expect to have countries allow only fans for young healthy adults up to 102.2 F, 100.4 F for healthy adults over age 65, and 98.6 F for older adults on select medications.

How is dumping a bucket of water overones self and then going out to stand in the wind a bad thing?

Why not take salt tablets?

Think of all the money people in the 19th century saved on electric bills.

If the elitists can’t vaccinate you to death, they’ll then try to starve you, take your job, your home, your property, your electricity, and healthcare and wait for you to succumb and be grub food.

The h311 A/C isn’t need. They should live in the heat/humidity without A/C. Morons.

Drove through the bottom of Ga. once. 100F, 100%. You had to be in air conditioning, or in water. Oh, and everything smelled like a garbage truck or a urinal.

I'm wagering that the eggheads coming up with this tripe, along with the political masters who would seek to enforce it, will not abide by it themselves.

They never do.

“35°C currently recommended by the WHO”

Is there ANYTHING that these people won’t butt their nose into? My God...the WHO telling us what temperature we should set our AC at.

I can’t wait for their diktat on the number of sheets of toilet paper I’m allowed and news about my increased chocolate ration.

Oh no, no, no.

I go kamakazi if they try and take air conditioning.

A bridge too far, WAY too far.

Nope.

Air conditioning will be illegal. You don’t need it. On the other hand, the chocolate ration may be increased to 20 grams.

Based on weather data from January 1, 2007 to December 31, 2019 the researchers found that contrary to many public health recommendations—including from the World Health Organization (WHO)—electric fan use for effective cooling without air conditioning could have been universally recommended for young healthy people during peak heatwave conditions in all populous cities in Bangladesh, China, Japan, Philippines, Indonesia, Canada, eastern regions of the USA, all of South America and Oceania and most of Europe (excluding some Mediterranean cities).

Fan use alone should not have been routinely recommended during hot weather in northern India, Pakistan, the Middle East, and the southwestern regions of the USA, because it would have regularly worsened heat stress.

You don't need air conditioning. A simple fan will do. You'll own nothing and be happy.

Actually in the dry SW, swamp coolers are useful. They add moisture/humidity.

article: “only when the air temperature is very high and humidity is extremely low that fans can be detrimental.

Obviously we Southerners have nothing to worry about.

What about in high humidity?

Here in the Southeast (Southern Alabama) USA, the humidity is near or at 100%, which means you sweat but nothing evaporates even with a fan. Then heatstroke happens.

People used to survive here because houses where built with large tall windows and a porch over them or sunshades. You built under shady spots or by water and shade. And of course, most hard work was limited. Today, modern housing is built with AC in mind, and can get extremely hot and humid inside without AC. Same thing for office buildings, like glass enclosed towers.

These people need to live here for just ONE Summer, and they’ll change their tune!

AC on 68
cool, dry air to breathe

Don’t like it? Screwel you.
I don’t care what you think about it.
You’re never coming over to my house.
