Feeling Unable to Breathe Deeply: What Could Be the Cause?

The feeling of not being able to take a deep breath or yawn, despite having normal oxygen levels, could be related to anxiety or conditions like asthma. Some people have reported this sensation during periods of high stress or after experiencing an asthma attack. It's also been associated with conditions like dysautonomia and is sometimes referred to as "air hunger". However, it's important to consult with a healthcare professional for an accurate diagnosis.
