Patient discussion about shift
Q. I started a new job a month ago – it’s night shifts as a security guard in a large office building I don’t know why, but I started feeling very down in the last week. Can it be that the change in waking hours is effecting me?
A. there are dozens of studies about night shift workers that try to connect them to all sort of things. and there is a good reason- our hormonal balance is maintained by our Hypothalamus (an area in the brain). being awake on night time changes it's function, it changes our hormonal system balance and other things around our brain. this can easily cause things like depression amongst some people.More discussions about shift
