Why is the hospital thermostat controlled by the one or two people who are NOT hurrying, lifting patients and dragging computer carts everywhere they go? You know what I mean. You arrive on the floor at 0630 and before you've even logged onto your computer, a sweat has broken out across the back of your neck. Now, I understand the challenges facing the night staff. They're fighting their diurnal rhythms. Of course they get cold, but they should throw on a scrub jacket. They should pull on a t shirt under their scrub top. Hell, they should pull on wool tights before they turn up that thermostat. Why? Because our patients sleep better when it's cool. Sleep is essential to the function of the immune system. Rest is essential to seriously ill people who have to try to muster the strength to get back on their feet. I have seen patients sweating off their NG tube tape. Shedding their IV securement and tegaderm. Stat locks on Foleys fall off. And IV tubing in a warm room becomes soft, folds over and occludes, setting off all the alarms. Delirious, confused patients pull at all these things because when they're sweating, tape itches. When it's warm enough, they pull off their gowns, too. There's no hope of hiding an IV up a patient's sleeve when they feel too hot to keep that sleeve on. I cannot help but wonder if the use of restraints goes up with the ambient temperature. Now, I worked the night shift for 18 months as a new nurse, so I'm not unsympathetic…and I know some places have policies limiting the type of jacket people are allowed to wear. And I know the day shift also harbors staff members who spend more time at their desk than a nurse or a CNA, people who take a chill, say, after lunch every day. But we all have other options open to us, and we should think twice before turning up the thermostat for either staff or visitors' comfort. Don't our patient's come first?
