One is that when we are bored or tired, we just don't breathe as deeply as we usually do. As this theory goes, our bodies take in less oxygen because our breathing has slowed. Therefore, yawning helps us bring more oxygen into the blood and move more carbon dioxide out of the blood.

You have sleep apnea. Because sleep apnea messes with your breathing during sleep, that drop in oxygen as you're dreaming can cause disturbing and vivid dreams, says Dr. Rosenberg. If you feel sluggish even after a solid eight hours or you snore frequently, you may want to get in touch with a sleep specialist.

If you're yawning between sets, decreasing the amount of weight you lift, and feel like you're constantly battling a cold, you might be working too hard in the gym. Training at too high of intensity or too often can result in overtraining, which can trigger adverse side effects that indicate you're working too hard.

For some people with sleep apnea, it may become a habit to sleep with their mouth open to accommodate their need for oxygen. Stress and anxiety can also cause a person to breathe through their mouth instead of their nose.

Frequent big variations on your estimated oxygen variation graph may indicate that you experience breathing disturbances during sleep. Breathing disturbances can lead to higher than expected variations in blood oxygen levels, which can indicate that your body is not getting enough oxygen while you sleep.

In addition, different regions of the brain control yawning and breathing. Still, low oxygen levels in the paraventricular nucleus (PVN) of the hypothalamus of the brain can induce yawning. Another hypothesis is that we yawn because we are tired or bored.

A part of the brain that plays an important role in yawning is the hypothalamus. Research has shown that some neurotransmitters (for example, dopamine, excitatory amino acids, nitric oxide) and neuropeptides increase yawning if injected into the hypothalamus of animals.

As humans, we use our diaphragm muscle to push and pull our lungs open and closed to help us breathe. Frogs inhale air through their nostrils, inflating skin sacs in their throats, then press down with the mouth muscles to force it into the lungs. If you've never seen a frog yawn, it's because they don't.

Although not fully understood, yawning appears to be not only a sign of tiredness but also a much more general sign of changing conditions within the body. Studies have shown that we yawn when we are fatigued, as well as when we are awakening, and during other times when the state of alertness is changing.

Heart problems Excessive yawning can be related to the vagus nerve, which runs from the bottom of the brain down to the heart and stomach. In some cases, excessive yawning may indicate bleeding around the heart or even a heart attack. Other symptoms that may indicate a heart problem include: pain in the chest.

Cools the brain Yawning causes a deep inhalation that draws cool air into the mouth, which then cools the blood going to the brain. Proponents of this theory claim a rise in brain temperature is observed prior to yawning, with a decrease in temperature seen after the yawn.

As Dr. Ochoa explains, dogs yawn when they are tired the same way that humans do. According to WebMD, yawning stretches the jaw, therefore increasing blood flow in the neck, face and head. The intake of breath is deeper than “normal” breathing, which causes a downward flow of the spinal fluid and blood from the brain.

Share on Pinterest Whilst yawning is often considered a result of being tired or bored, this may not always be the case. Yawning is commonly thought to be a sign of sleepiness or boredom, though this is not always the case. While someone who yawns may be tired, the heart rate quickly rises during a yawn.

Yawning excessively can occur when you are tired, weary or drowsy. Some medications, such as those used to treat depression, anxiety or allergies, can cause excessive yawning. Yawning excessively may be related to a lack of sleep caused by a sleep disorder, a change in daily habits, or a change in work hours.

A new study shows that “yawn transmission” is more frequent, and faster, between people sharing an emotional bond: close friends, kin, and mates. Everybody knows that yawning is contagious. When a person yawns, other people can respond by yawning.
