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。
