There have been recent studies by the Annals of Internal Medicine regarding the use of air conditioning or fans for cooling.
Whether you’re in Toronto or New York with high humidity or in low humidity areas such as Johannesburg, or Sydney, there is one aspect of living that is required for survival – Cooling.
What is Cooling?
Personal Cooling is the effect of lowering body temperature, either through evaporation or heat dissipation.
What is Heat Index?
“Heat Index is a commonly used weather metric that expresses both air temperature and relative humidity” – https://www.sciencedaily.com/releases/2019/08/190805181627.htm
It might be beneficial to understand how we can automate our air conditioning or use fans to help us get the best cooling effect.
Cooling in High Humidity
In a place like Toronto or New York, heat waves arrive with high humidity. The effects of such heat indexes are dangerous to the young, old, and those with health problems.
The study from the University of Sydney showed that the use of fans in hot and dry conditions actually makes it worse for the body. Your body cannot produce enough sweat in dry conditions because it’s trying to keep the moisture, so blowing air over your body during hot-dry conditions is BAD. You’re simulating a convection oven – good time to start the Air Conditioning if you have one, or get some misting devices to help you cool down.
What does this mean for Hot-Humid locations like Toronto, New York? Well, the fan can actually provide more benefit in this situation. In humid conditions, your body is producing sweat, so having a fan blowing directly on you will actually help you lower your body temperature and evaporate the sweat. However, the air conditioning unit will also help reduce the humidity and cool the air as well. If you don’t have air-conditioning and want to reduce your bill, direct fans are probably the way to go.
Home Automation for Hot Environments
If it’s hot and dry – maybe don’t automate your electric fan. Telling it [fan] to turn on right away when it’s hot and dry, may not help you get cool or it may actually be more detrimental. You can ask your smart thermostat to turn on the Air Conditioning if you have one, and don’t forget to stay hydrated – drink some water.
If it’s hot and humid – it might be more beneficial to blow air directly over the sweat on your body to cool your core temperature. This is where you can automate your home to turn on smaller fans to direct air over your body, or create a draft.
One other thing; there are tons of home automation devices that actually measure the temperature and humidity so you can automate the cooling in your home! You’ll find temperature and humidity sensors on our Amazon affiliate site (small proceed may go to Automate Your Life) here.
I am going to test out these theories in my own home. You will read about my experiences in future blog posts and the community. If you would like to add to the ‘being-cool’ debate, or even share how you cool your home with automation, please join us at:
