Lie back on a couch with your legs higher than your heart.
躺平，腿抬高
This lets blood that has pooled in your legs drain downhill toward your heart. For a more active approach, lie on your back near a wall, placing your heels on the wall with your legs at a 45-degree angle. Hold the position for three minutes.
这招会使集中在腿部的血液倒流回心脏。更有效的做法是，靠近墙壁仰躺，将脚后跟放在墙上，双腿和墙壁呈45度角，此姿势保持三分钟。
