Why Planes Are So Cold and What You Can Do About It
Flying can be an exciting experience, but it’s not without its challenges. One of the most common complaints among passengers is the chilly temperature inside the cabin. While it might feel uncomfortable, there’s actually a scientific reason behind this. Understanding why planes are cold can help you better prepare for your next flight and stay comfortable.
The primary reason for the low temperature in airplanes is related to the air pressure and oxygen levels at high altitudes. At cruising altitude, the air outside the plane is much thinner, which means there’s less oxygen available. To compensate, planes circulate a mix of fresh air from outside and recycled air that has been filtered through HEPA filters. However, this process can result in lower temperatures inside the cabin.
Another factor contributing to the cold environment is the need to maintain a safe level of oxygen for all passengers. Warm air holds more moisture, which can lead to discomfort and even fainting in some cases. By keeping the cabin cooler, airlines ensure that passengers remain alert and comfortable throughout the journey.
Despite the chill, it’s important to remember that the air vents on airplanes are designed to keep the air circulating and clean. Many people assume that the air vent is one of the dirtiest surfaces on a plane, and they’re not entirely wrong. A study by Travelmath found that the air vent had more bacteria per square inch than the flush button in the airplane bathroom. However, closing the vent isn’t the solution. In fact, doing so can trap viral particles in your personal space, increasing your risk of getting sick.
Instead of closing the vent, experts recommend adjusting the airflow to suit your needs. Dr. Mark Gendreau explains that the air coming from the vents is a 50/50 mix of fresh and HEPA-filtered air, which removes 99.99% of bacteria and viruses. To avoid feeling too cold, you can direct the airflow slightly away from your body, such as in front of you or downward. Just remember to use hand sanitizer after touching the vent to reduce the spread of germs.
Tips for Staying Warm During Your Flight
If you’re looking for ways to stay warm during your flight, there are several practical strategies you can try. One of the simplest is to dress in layers. This allows you to adjust your clothing based on the temperature changes throughout the flight. A cozy hoodie in your carry-on can be a lifesaver if you start to feel chilly. It’s also a good idea to bring a scarf, which can serve multiple purposes. According to travel expert Samantha Brown, a good scarf is like the Swiss Army knife of travel clothing, offering warmth and versatility.
In addition to layering, you can also use the seat cushion or blanket provided by the airline to add extra comfort. Some airlines offer heated blankets or neck pillows, which can make a big difference in your overall experience. If you’re traveling during the winter months, consider bringing a small thermal blanket to keep yourself cozy.
Additional Ways to Stay Healthy on a Plane
Staying healthy during a flight involves more than just managing the temperature. Hydration is key, as the dry air in the cabin can cause dehydration. Drinking plenty of water throughout your trip helps maintain your energy levels and supports your immune system. Avoiding alcohol and caffeine is also a good idea, as they can contribute to dehydration.
Washing your hands frequently is another essential practice. The air vents and other high-touch areas on the plane can harbor germs, so using hand sanitizer or washing your hands with soap and water can significantly reduce your risk of illness. Additionally, using a face mask can provide an extra layer of protection, especially if someone near you is coughing or sneezing.
By understanding the reasons behind the cold temperature in airplanes and taking proactive steps to stay comfortable and healthy, you can make your next flight more enjoyable. With the right preparation and mindset, even the coldest flights can become a more pleasant experience.
