It has also been shown that sunshine coming in a patients room makes them happier and they recover quicker, even if it is only for a few hours a day. Really aren't we all happier with a little sunshine?
So how does this relate? While helping with a patient the other day who was stubborn about ambulating two days after heart surgery, but it was time for him to move. A co-worker who would not take no for an answer got him up as he complained while squeezing his heart shaped pillow to his chest.
Being the good assistant and trying to make the patient feel better I said I would grab him some clean sheets, as I ripped the old ones off the bed. As they flew off and traveled through the air a plume of dust, aka dead skin illuminated in the sunlight of the patients window. Not wanting to breath in what I was seeing I did the old nurses trick of holding my breathe and walking away towards imaginary clean air, but there really is no such thing in a hospital. I really can't imagine how many things we breath in during a shift at work.
