噘唇呼吸法與腹式呼吸

噘唇呼吸法 (pursed lip breathing)
緩慢地從鼻孔深深吸氣
從皺起的嘴唇緩慢呼氣
(Chinese version from Hong Kong Association of Gerontology)

To do pursed lip breathing: Relax your neck and shoulder muscles. Breathe in for two seconds through your nose, keeping your mouth closed. Breathe out for four seconds through pursed lips. If this is too long for you, simply breathe out twice as long as you breathe in.

腹式呼吸是讓橫膈膜上下移動。由於吸氣時橫膈膜會下降，把臟器擠到下方，因此肚子會膨脹，而非胸部膨脹。因此，吐氣時橫膈膜將會比平常上升，因而可以進行深度呼吸。

Diaphragmatic breathing is breathing that is done by contracting the diaphragm, a muscle located horizontally between the chest cavity and stomach cavity. Air enters the lungs and the belly expands during this type of breathing.

鍛鍊橫膈膜呼吸時,宜以鼻呼吸,切忌以口吸氣。鼻腔溫暖、濕潤,專責過濾空氣,令進入氣管的空氣溫度適中、濕潤和較清潔,減低對氣管的刺激。
