It was once believed that the main function of yawning was to increase otherwise low oxygen levels, but a 1987 study disproved that theory. ... such as a spiked heart rate and increased skin ...
Yawning may be an offshoot of the same imitative impulse. A 2007 study found that young children with autism spectrum disorders do not increase their yawning frequency after seeing videos of other people yawning, in contrast to non-autistic children. In fact, the autistic children actually yawned less during the videos of yawning than during ...

328 participants were asked to watch a three-minute video of people yawning and to keep track of how many times they yawned. Of the 328 participants, 222 contagiously yawned.
Drugs can greatly influence the rate of respiration. Opioids and anesthetics tend to depress ventilation, by decreasing the normal response to raised carbon dioxide levels in the arterial blood. Stimulants such as amphetamines can cause hyperventilation. Pregnancy tends to increase ventilation (lowering plasma carbon dioxide tension below ...
Those are times to seek out help because it may not be a reflection of your resting heart rate, but an abnormal heart rhythm that should get evaluated.” Having a pulse over 100 bpm is called ...
Bainbridge reflex - increasing heart rate in response to increased central venous pressure. Baroreflex or baroreceptor reflex — homeostatic countereffect to a sudden elevation or reduction in blood pressure detected by the baroreceptors in the aortic arch, carotid sinuses, etc.
The most efficient way to lower your heart rate is through breathing, says Dr. Wang. “Deep exhalations can decrease your heart rate. Breathing in through the nose for the count of 4, holding it ...
