Yawning is a natural reflex that helps regulate oxygen levels and keep the brain alert. However excessive yawning could be the sign of an underlying health condition.
Experts warn that while yawning is often linked to sleepiness or boredom, frequent and persistent yawning could be a sign of underlying health conditions, including iron deficiency, heart issues, and neurological disorders.
Experts remind us that iron is essential for oxygen transport in the blood so when iron levels are low, oxygen delivery in the body decreases, causing the body to yawn more frequently to boost oxygen intake.
So if you are concerned about your excessive yawning, please consult your Doctor. If the cause is iron deficiency, this can be determined by a simple blood test.
