Yawning is a normal physiological reaction, and scientists generally believe that yawning helps with deep breathing, increases oxygen levels in the blood, and enhances brain activity. However, if yawning occurs frequently, even five to six times in a short period, it may not only indicate fatigue but also serve as a warning sign of certain diseases.

Frequent Yawning May Be a Sign of Three Major Diseases

Dr. Lü Yixing, an otolaryngologist at Mackay Memorial Hospital, points out that people with enlarged oral tissues or tonsils are more likely to yawn frequently. In addition, those with heart, liver, or kidney dysfunction, as well as patients with sleep apnea, may also experience frequent yawning. Moreover, people with Parkinson’s disease or stroke may exhibit this symptom due to brain and body coordination abnormalities. If you experience persistent yawning, be aware of the following three potential health risks:Three major disease warning signs that cause yawning. (Image provided by Heho Health)

Cardiovascular Disease

The heart is responsible for supplying blood to the entire body and brain. If coronary artery disease, myocarditis, or valvular disease occurs, it can affect blood circulation, leading to brain hypoxia and frequent yawning. People with a history of heart disease should be vigilant if they experience frequent yawning, as it may indicate worsening heart function. If symptoms such as chest tightness, back pain, fatigue, or cold sweats accompany yawning, immediate medical attention is necessary to avoid serious complications.

Cervical Spine Disorders

The cervical spine connects the brain and body, playing a crucial role in nerve transmission and blood circulation. Degenerative changes or spinal stenosis can compress blood vessels and nerves, reducing blood flow to the brain and causing frequent yawning. Severe cervical spine conditions may also lead to numbness in the hands and unstable walking. Early medical intervention is advised to prevent further complications.

Stroke

Clinical observations indicate that 60% to 80% of stroke patients experience frequent yawning 5 to 10 days before the onset of the condition. This is due to slowed blood flow caused by high blood pressure or cerebral arteriosclerosis. When the brain is in a state of chronic hypoxia, the body compensates by yawning to promote circulation.People with enlarged oral tissues and tonsils are more prone to frequent yawning.

People with high blood pressure, diabetes, and high cholesterol should be alert if they start yawning frequently without a clear reason. Seeking medical attention promptly can help prevent stroke.

Experts warn that if yawning occurs persistently along with other physical discomforts, medical consultation is necessary to ensure overall health.
