In the process of yawning, someones make an involuntary action in which a person open its open widely and breath in deeply. In this type of action, air fills the lungs, pushing down the person’s diaphragm and making the abdominal muscles flex. In the result, excess carbon dioxide pushed out from the body and replaced with the oxygen. A person yawns each day, but too much yawning can be a health problem. The possible health problems can be central sleep apnea and a sign of sleep disorders, for example, insomnia. In the case of frequent yawning, someone’s cannot sleep properly at night time.

Pure oxygen causes the brain to release hormones and chemicals that calm you down, which is probably why you take a deep breath to get more when you are upset.

If an individual has excessive sighing, then it can be a symptom of anxiety disorder and panic disorder.
