What Are the Common Causes of Feet Swelling After a Long Flight?
Feet swelling after a long flight often occurs due to prolonged sitting and other contributing factors. This phenomenon is medically known as edema, where excess fluid builds up in the tissues.
Common causes of feet swelling after a long flight include:
1. Prolonged immobility
2. Air pressure changes
3. Dehydration
4. High salt intake
5. Existing health conditions
Understanding these causes provides insight into how to manage and prevent swelling during air travel.
-
Prolonged Immobility:
Prolonged immobility during a flight can lead to poor circulation. When passengers sit for extended periods, blood flow slows, particularly in the legs and feet. According to a study by the Journal of Vascular Surgery (Miller et al., 2018), immobility increases the risk of venous stasis, contributing to swelling. -
Air Pressure Changes:
Air pressure changes in airplane cabins can affect fluid distribution in the body. The cabin pressure is lower than at sea level, which causes gases in the body to expand. This change can lead to an increase in fluid retention in the lower extremities. The American Journal of Physiology (Mackey et al., 2017) notes that this fluctuation may heighten swelling, especially in susceptible individuals. -
Dehydration:
Dehydration during flights can contribute to swelling. Since the airplane cabin is often low in humidity, passengers may not realize they are dehydrated. Dehydration can lead the body to retain water, causing swelling. The National Institutes of Health (NIH, 2021) emphasizes the importance of hydration for proper circulatory function. -
High Salt Intake:
High salt intake before and during flights can exacerbate water retention and swelling. Sodium causes the body to hold onto water, leading to edema in the feet.
