Hello I had a question for some of the medics here. I looked into sleeping less when my schedule changed at work. As of now I am working 5 12 Hour shifts a week at a Pipe yard doing medical response. I usually sleep 7-8 hours when I get off but it gives me little time to do other things that I need to do. I was recently injured off the job and have a Tendon in my ankle that is out of place. I have been doing PT for this injury, but have had little time to do the exercises due to my work schedule. Is 5-6 Hours of sleep per day enough or should I just abort trying this? Is anyone out there functioning on less than 8 hours of sleep and still able to be in a good mood and be alert for doing task?
