Experts: Why You Shouldn't Turn Off Airplane Air Vents
When you fly, the air vent above you is actually pretty important!
Experts say it's best to keep it on.
Airplane air filters clean the air, and the vent helps push away germs.
If you turn it off, you might feel stuffy or sleepy.
Instead of turning it off, adjust it to low or medium.
Angle it toward your chest and bring a scarf or sweater if you get cold.
This keeps you comfy and healthy!
Experts advise against turning off airplane air vents.
Air vents circulate fresh air and filter out harmful particles.
Reduced ventilation can increase stress and sleepiness.
Adjust the vent's setting to a comfortable level.
Use a scarf or sweater to manage temperature.
