A third way to reduce breathlessness in activity is to keep it close. So bring the work space up in front to waist level so there is no reaching and bending. This lessens the load on your heart and lungs thereby reducing the energy need and your level of breathlessness.
This can be done by putting the task on the table in front and sitting or by doing it on a table in standing or at a bench. The other way we have talked about previously is to have important daily used items on shelves between hip and shoulder height thereby bringing the activity closer to waist level.
This is the same for if you are lifting or moving items. Keeping it close reduces the strain on your arms and reduces your level of breathlessness. Remember never to hold your breath whilst you are lifting but continue to blow out through pursed lips in a gentle manner, always looking for ways to slide the load , break it up or use a trolley.
