Low levels of oxygen, also known as hypoxia, can seriously harm the brain. Here’s why:

Hypoxia can be caused by choking, drowning, heart attack, severe asthma, chronic obstructive pulmonary disease (COPD), high altitudes, or carbon monoxide poisoning.

The brain uses about 20% of the body’s oxygen. Oxygen is crucial for brain cells to work properly.

When oxygen is low, brain cells can't make enough energy. This stops important processes and causes harmful waste to build up. Brain cells can start dying within minutes.

When cells die in one area, it may harm nearby brain tissue too. This can affect memory, movement, and thinking.

The longer the brain lacks oxygen, the worse the damage. A few minutes of low oxygen might cause temporary confusion or dizziness. But longer periods may cause permanent damage.

Even after oxygen levels return to normal, the brain may struggle to repair itself, leading to lasting impairments and a lengthy recovery process.

If someone is suffering from any of these conditions, they need immediate medical help to prevent hypoxia.
