WHY DOES YOUR CHEST BEGIN TO BURN IF YOU HOLD YOUR BREATH TO LONG?

This is because the body organgs need O2 for respiration (aerobic - respiration ) . If O2 is not provided then annarobic respiration occurs which leads to formation of "ETOHONAL".

Which leads to burning of chest.

Cause of the co2 in ur body. co2 can burn your insides.

When you hold your breath for too long, you might experience a burning sensation in your chest. This could be due to multiple factors, including increased carbon dioxide (CO2) levels in your body and the buildup of lactic acid.

When you breathe in, your body takes in oxygen and releases CO2 as a waste product. Normally, you continuously exhale CO2, keeping its levels in your body relatively low. However, when you hold your breath, you prevent the release of CO2, causing its levels to rise in your bloodstream. This increase in CO2 triggers a response in your body that makes you feel the urge to breathe again.

At the same time, the buildup of lactic acid can contribute to the burning sensation in your chest. Lactic acid is a byproduct of anaerobic metabolism, which occurs when your body is unable to supply enough oxygen to your muscles. Holding your breath for an extended period of time limits the amount of oxygen available to your muscles, leading to the production of lactic acid. This can cause a burning sensation or discomfort in your chest area.

It's important to note that holding your breath for too long can be dangerous. When you feel the urge to breathe, it's a sign that your body needs oxygen. Ignoring this urge for too long can result in oxygen deprivation, reduced brain function, and even loss of consciousness.
