Is it better to use a high or low pillow when sleeping at high altitudes?

In general, when experiencing altitude sickness, it is better to sleep with a higher pillow. The detailed explanation is as follows:

The air at high altitudes is thinner and contains less oxygen. Elevating the head with a higher pillow helps keep the airway more open, making it easier to inhale more oxygen. A low pillow may cause the head to sink downward, compressing the airway and increasing the sensation of breathing difficulty. An insufficient pillow height might restrict airway patency and worsen the respiratory distress caused by altitude sickness. Additionally, headaches and insomnia are common symptoms of altitude sickness. Using a higher pillow can improve blood circulation in the head, helping to relieve headaches and enhance sleep quality. Moreover, altitude sickness due to hypoxia often leads to edema. Elevating the pillow can assist in draining fluid from the face and head, reducing discomfort.

In summary, sleeping with a slightly elevated pillow can help alleviate symptoms of altitude sickness, but care should be taken not to make the pillow too high. It is recommended that individuals experiencing altitude sickness seek prompt medical evaluation at a正规 hospital to prevent worsening of symptoms.
