What Makes you Yawn During a Workout

#

Working out has many effects on your body. When weight training, your muscles tend to swell, skin tightens, and veins become exposed. When performing core defining movements, your abs become very tight and can stay that way for some time when done in excess. These are very natural bodily reactions that we expect to occur during a specified workout. Something that many individuals do not expect to do while working out is yawn. You aren’t tired or bored, yet you find yourself yawning during a workout. Why is that?

Why You Yawn During a Workout

Don’t panic; yawning during a workout is completely natural. No, it does not mean that you should go take a nap or make your training regimen more exciting, but rather it’s your body’s way of cooling down. When you yawn you don’t only increase the amount of blood travelling to your brain, but you also lower the blood temperature. During an intense workout, your body can become extremely hot depending on training conditions. A yawn serves as an air conditioner for the brain, preventing the possibility of fainting or nausea.

You may be familiar with the bodily reaction of sweating when your body is hot but not yawning. That is because your body does not always need to yawn to regulate temperature. You are more likely to yawn in moderate temperatures like the confinements of a gym, rather than in extremely hot or cold outdoor conditions. When it is too cold, your body is already focusing on warming up even before you start exercising. When it is too hot, the air from your yawn is not cool enough to cool down your brain.

The reason your body needs blood to the brain during a workout is because strenuous workouts and movements require a large amount of blood flow. This is evident in the resulting effect of swelling veins. The blood yielded is likely diverted from the brain and yawning is your brain’s way of reclaiming that blood.

Dangers of Excess Yawning

Yawning is natural but excess yawning can be dangerous. A couple yawns here and there during a workout  is normal and to be expected when performing intense exercises like deadlifts and squats. If your yawns are excessive and begin interfering with your workout, we suggest you take a break. Yawning too often can be an early sign of an oncoming dizzy spell or panic attack. It is suggested you visit a doctor if this occurs repeatedly. It can be an indicator of a larger blood flow or body temperature problem.

The next time you yawn during a workout, thank your brain. The intensity of your workout may be robbing it of much needed blood flow.
