The human body needs oxygen in order to survive and functions at its best when it has enough of the gas. The danger of low oxygen levels for humans is a well-known problem, with the World Health Organization estimating that around 1.4 million people die every year due to prolonged exposure to low concentrations of oxygen.

The oxygen level can go below 90% before you die.

I hope you get the answer to the question “ how low can your oxygen level go before you die?”
