Why should you not close the air vent above the airplane seat?

The temperature in the airplane cabin usually gets colder with increasing altitude. Since airplane blankets are one of the most polluted items on the plane, it is recommended not to use them. Perhaps the best way to stay warm is to close the air vent above the seat; But closing this valve can be even more dangerous for your health than using contaminated blankets and pillows. According to some medical experts, even if you feel cold, it is better to leave the air vent open.

How does an airplane vent help your health?

You may have heard that the recirculated air in the plane is harmful to your health or causes colds and even corona virus; But in reality, the air coming out of the vents above your head is much safer than the air remaining in the cabin. The air from the vents contains fresh oxygen from outside the aircraft, which is mixed with the air inside the cabin and purified using high efficiency air filters (HEPA). According to the International Air Transport Association (IATA), these filters, which are similar to hospital filters, remove more than 99.9% of airborne bacteria, viruses and fungi.

The air in the cabin is constantly refreshed, so even without using the air vent, you breathe some fresh air; But opening the vent will ensure that you get the best air quality and prevent the accumulation of germs around you. If you catch a cold too soon, there is a solution; There is no need for the valve to blow directly in your face. It is enough to set the valve slightly ahead of you and downwards.

Tips for comfort and health when traveling

Leaving the air vents above your head open should be your regular habit when flying. However, keep a few tips in mind to avoid catching a cold. First, the best coverings for flying are layered clothing that you can add or subtract depending on the cabin temperature. Some research shows that extreme cold can weaken the immune system; Therefore, to avoid getting sick during the trip, be sure to have a warm jacket or sweater available.

Also, the drying of the sinuses increases the risk of contracting the disease, and the flow of cold air towards the face can aggravate this dryness. To protect yourself, drink plenty of water during the flight and use a saline nasal spray if needed. If you suffer from dry eyes, it is better to have moisturizing eye drops with you.

Finally, take steps to keep your skin hydrated. Dry skin can cause cracking and infection if exposed to bacteria. If you have a long flight and will be sitting under an air vent for several hours, use a rich face moisturizer and hand lotion before your flight to create a protective barrier for your skin.
