Yawning is not only very contagious, but a new study has discovered that it helps clear deoxygenated blood and waste products in the cerebrospinal fluid from our skulls.
Biomechanical engineer Lynne Bilston, an author on the study, talked with Flora about the findings and what they could mean for neurodegenerative diseases like Alzheimer’s. Listen to the podcast now on our YouTube channel.
P.S. Our social media manager yawned no less than 50 times while making this post. We do apologize for all the extra yawning we may have caused.
