Why is it not advisable to sleep in a closed room with shouldering fire in it?

Answer 1

During daytime plants have photosynthesis, which enables them to consume and convert atmospheric CO2 into O2, while during night reverse happens as photosythesis can not take place due to absence of sun light. Plants breathe in which CO2 is exhaled while O2 is consumed.

So, if someone sleeps in an enclosed room with plants, the level of CO2 may go beyond tolerable level of humans, which might eventually suffocate and kill humans. That is why we are adviced not to sleep in enclosed room full of plants.

Answer 2

Under insufficient oxygen levels, coal burn can result in a huge amount of carbon monoxide. Carbon monoxide is hazardous, and can reach a lethal dosage in rooms with bad ventilation. It can bond to blood cells(much stronger than oxygen), making that blood cell unable to carry oxygen.

Answer 3

Sleeping in a closed room with a smoldering fire can lead to a build-up of carbon monoxide, a colorless and odorless gas that can be deadly when inhaled in high concentrations. It can displace oxygen in the room, leading to suffocation. It's important to always ensure proper ventilation when using fires indoors to prevent carbon monoxide poisoning.

Answer 4

The fire consumes oxygen and gives of carbon monoxide. The Carbon monoxide will take the place of oxygen, but your body cannot use it, so you can smother, even if you are not asleep.
