Economy Class Syndrome

Have you ever felt swelling in your legs after sitting in an airplane for a long time? This is due to the stagnation of blood in the veins, causing the fluid in the blood to drain out. The loss of fluid in the blood causes blood clots in the veins, and in rare cases, these clots can get stuck in the blood vessels of the lungs and cause breathing difficulties. This is called an economy class syndrome.

Prevention and remedies

  • – Exercise by lifting your heels and toes up and down.
  • – Massage calves.
  • – Drink plenty of fluids and avoid alcohol.
  • – Take deep breaths from time to time.

Flying rapidly between time zones that are more than 5 hours apart can cause a discrepancy between the body’s internal rhythms and actual living time, resulting in symptoms such as insomnia, nausea, fatigue, loss of appetite, and decreased ability to work. This is known as jet lag syndrome. Generally, symptoms are more severe when flying eastward than when flying westward.

Countermeasures against jet lag syndrome

It is important to ensure adequate sleep and rest before heading for departure. Alcohol can also disrupt sleep rhythms, so taking of alcohol should be moderate.
