* Blankets and pillows are not always washed after each use. Some airlines do not have the resources to wash all of their blankets and pillows after each flight, so they may be reused multiple times. This can increase the risk of spreading germs and bacteria.

* Blankets and pillows can be contaminated with bodily fluids. When passengers sleep on blankets and pillows, they can leave behind bodily fluids, such as saliva, sweat, and urine. These bodily fluids can contain bacteria and viruses that can be spread to other passengers.

* Blankets and pillows can be contaminated with dust mites. Dust mites are tiny creatures that live in dust and fabric. They can cause allergies and asthma in some people.

* Blankets and pillows can be contaminated with other allergens. Other allergens, such as pollen and pet dander, can also be present on blankets and pillows. These allergens can trigger allergies and asthma in some people.

To reduce the risk of exposure to germs and bacteria, you can take the following precautions:

* Bring your own blanket and pillow. This is the best way to ensure that you are using clean bedding.

* If you must use the airline's blanket and pillow, inspect them for signs of dirt or stains. If you see any dirt or stains, ask for a new blanket and pillow.

* Wash your hands before and after using the blanket and pillow. This will help to prevent the spread of germs and bacteria.

* Avoid touching your face while using the blanket and pillow. This will help to prevent the spread of germs and bacteria to your eyes, nose, and mouth.

* If you have allergies or asthma, be sure to bring your own bedding and medication. This will help to reduce your risk of exposure to allergens and triggers.

By following these precautions, you can help to reduce the risk of exposure to germs and bacteria when using airline blankets and pillows.
