Exhaled Co2 facts
While investigating facts about Exhaled Co2, I found out little known, but curios details like:
For every 1lb/kg that someone loses, 86% of it is breathed out of the body in the form of CO2. The body literally exhales the majority of its weight loss.
Mosquitoes prefer O-type blood, people with high body heat, pregnant women and heavy breathers. Many of these reasons are because mosquitoes can sense carbon dioxide (CO2) from up to 100 feet away. Which is a reason why they circulate around our heads where we exhale CO2.
In my opinion, it is useful to put together a list of the most interesting details from trusted sources that I've come across. Here are 14 of the best facts about Exhaled Co2 I managed to collect.
-
When you lose 10 kg of fat, 8.4 kg is exhaled as CO2 and 1.6 kg is excreted as water. Most of the weight you lose exits your body through your lungs.
-
Astronauts sleeping in zero-G must do so in a well-ventilated area, or they risk exhaling a bubble of CO2 around their own heads and suffocating.
-
Without gravity, there is no air convection, and without forced air circulation you'd die from heat, and suffocation from the CO2 bubble formed by your exhalations.
-
Astronauts must sleep next to air vents. The CO2 they exhale in their sleep will not dissipate in zero gravity, meaning they will suffocate if there is no immediate circulation.
-
Mosquitoes are attracted to high concentrations of CO2 in the air, and using a fan to generate even a weak wind helps protect people from mosquitoes, by dispersing the CO2 that they exhale.
-
When losing weight 84% of fat is exhaled as CO2 and the remaining 16% is excreted as H2O
-
The Lascaux caves had to be closed to the public because the the body heat, exhaled CO2 and humidity, and fungi of visitors visibily deteriorated 17,000 year old paintings in just 7 years.
-
Mosquitoes are not attracted by light but by the CO2 we exhale.
-
The ISS uses electrolysis to create oxygen - then uses the hydrogen byproduct along with exhaled CO2 to recover water in a process known as the Sabatier Reaction.
What is true about exhaled co2?
You can easily fact check it by examining the linked well-known sources.
When you burn fat, you exhale it in the form of co2, and urine the rest off the mass in the form of water
Only 16% of the fat we burn leaves our body as a liquid (urine, sweat) while 84% leaves as exhaled CO2 from our lungs. - source
