You're moving at 500 miles per hour in the air. As the air inside the plane, your body is also pressurized. It directly affects your senses, like smell and taste. You start to lose your sense of smell when you're in that tight space and so high in the sky. Tasting is as much about your nasal passages as it is about your taste buds. As the plane gets higher, the air pressure drops while humidity levels plummet. At about 30,000 feet, humidity is less than 12%, which is drier than most deserts. The combination of dryness and low pressure reduces the sensitivity of your taste buds to sweet and salty foods by around 30%. #sciencegyan #amazingfacts #sciencefactsdaily #scienceamazingfacts https://www.instagram.com/p/CVFLDg2tDaw/?utm_medium=tumblr
