What harm does regular contact with methane have to the body?

Methane is basically non-toxic to people, but when the concentration is too high, the oxygen content in the air is obviously reduced, which makes people suffocate. When the methane in the air reaches 25%-30%, it can cause headache, dizziness, fatigue, inattention, rapid breathing and heartbeat, and ataxia. If you don't stay away in time, you may suffocate. Skin contact with liquefied methane can cause frostbite.

Methane poisoning: acute poisoning, methane toxicity is very low, and the "methane poisoning" caused by exposure to high concentration methane is actually due to hypoxia and suffocation caused by the relative reduction of oxygen content in the air. Allow gas to safely diffuse into the atmosphere or be used as fuel. There are simple asphyxia and high concentration hypoxia asphyxia leading to poisoning. When the air reaches 25 ~ 30%, dizziness, accelerated breathing and dyskinesia occur.
