Yawns: You’re next. 🥱 I. Must. Not. Yawn. After reading this, there’s a 50% chance you’ll yawn. No? Well, we didn’t really have any scientific metrics to back up that statement. Moving on. Did you know tortoises sleep when it’s dark? (Come for the tortoise yawn, stay for the facts.)This a diurnal sleep schedule, so they’re awake when it’s light and asleep when it’s dark. Many humans have similar schedules, unless you prefer to lie awake in bed, looking at the ceiling, deeply thinking about the meaning of life, the universe, or wondering where you put your birth certificate? P.S. A tortoise follows a monophasic sleep schedule, sleeping for about 12 hours without waking up. Nice. Video: A desert tortoise delivers a long yawn.
