CO2 Tolerance

The role of carbon dioxide (CO2) tolerance in managing anxiety is significant. Tanya Bentley explains that higher CO2 tolerance can reduce in-the-moment anxiety, while lower tolerance can exacerbate it. This is because CO2 tolerance affects how well oxygen is delivered to tissues, impacting overall stress levels 1. Bentley suggests that improving CO2 tolerance can be achieved through simple breathwork practices, which can help the body better handle stressors like anxiety-inducing situations 2.

We actually need more carbon dioxide in our bloodstream in order to have greater access of oxygen to our tissues.

These practices involve slow, diaphragmatic breathing, which enhances lung health and oxygen saturation, potentially benefiting those with conditions like long COVID 2.

   

Hyperventilation

Hyperventilation can significantly impact anxiety levels and overall health. Tanya Bentley highlights that chronic hyperventilation, characterized by rapid mouth breathing, can lead to various health issues, including respiratory and immune system problems 1. This type of breathing keeps the body in a heightened sympathetic state, feeding anxiety and preventing proper recovery.

Hyperventilation is just really meaning over breathing a lot through the mouth and fast breathing.

--- Tanya Bentley

Controlled breathwork can mitigate these risks by promoting a balanced CO2 and oxygen level in the body, essential for optimal tissue oxygenation 3. Bentley emphasizes the importance of nasal breathing and diaphragmatic techniques to maintain this balance and prevent the adverse effects of hyperventilation 1.
