Is night shift healthier for some people?

Nurses General Nursing

So I work days, which as a new RN can be difficult to get. I've worked a bit over a year.

We're a busy floor. I am typically out late, between 4:30 - 5pm (supposed to be 7 - 330 shift). I usually am unable to get a lunch, so either don't eat, or eat worse than I'd like to when I get home. I usually get VERY hungry before bed, but try to avoid eating right before bed. I usually scarf down some breakfast. I never used to eat breakfast because it made me sick (nausea) but I would just be so hungry from not eating all day, so I made myself.

Any who I've read through many topics here that state how unhealthy night shift can be on the body. I'm very health conscious. I feel like days isn't that healthy because of my eating habits. But will nights really increase my risk of hypertension/cancer/diabetes/weight gain/ etc??

I'm only asking because I feel like I may be more nocturnal. For one I can eventually fall asleep whenever. But even on my days off when I wake at about 9am I want to take a nap by noon. I have a VERY hard time going to sleep before 2 am or so.

I start to become really energized late in the evening like 8pm or so. I have an *extremely* hard time waking up in the morning. Even if I had 8 to 9 hours of sleep. I have to drag myself out of bed and am often sleepy until noon. Also the most stressful things for me on days - dealing with doctors, families, and lack of teamwork - is minimal on nights.

I did a night shift once before and it was fine for me. But it was only one shift.

Thoughts/experience?

Where did i criticize anything? You are the one giving out information not me. I was asking for facts. Are you sayong if i find somethong on google it is always true? Anyone who claims to KNOW something as always true then i expect evidence

Is that wrong? Chill out

Why don't you do some research of your own? Read a couple of journal articles- that way you can chill.

I did give facts, and then pointed you to some research backing them up. And why are you so upset that I attempted to share information with a fellow night shifter? I am truly puzzled what you are so angry about.

It is for me... I tried day shift at my current facility and about had a heart attack from the stress of day shift.

Nights is much less stressful. =)

My spouse works nights - not in health care - and has for years. He would not trade it for anything. He hated working days and for him, his health is better, his attitude is better and he is happier on nights so I think, yes, for some, it does fit well.

I do NOT function on day shifts like I can on nights. The thought of being tired rarely crosses my mind on nights. During the days I worked, it would be there at about 1000

This topic is my passion in life- in case you could not tell! :)

As far as melatonin goes, it is produced whenever you sleep basically. Production is suppressed by sunlight hitting the retina. So if you are sleeping in a DARK room, you ARE producing melatonin during daytime sleep. Wearing sunglasses on the drive home- putting them on before you even walk outside the building, really helps with revving up melatonin production and sleep induction. Cortisol is secreted in exactly the opposite circadian pattern.

I'm not sure that's totally accurate, while you will produce some melatonin when sleeping during the day, it's a much smaller amount and your total melatonin production is still lower (and total cortisol production still higher) which has been associated with the higher rates of health conditions in night shift workers. Circadian rhythms can't really be overridden, you can minimize the effects as much as possible, but sleeping counter to your circadian rhythm (which is set by environmental cues) will always result in decreased melatonin production and a resulting rise in health risks.

Yes, melatonin secretion is lower when one sleeps during the daytime. But, while environmental cues ARE important, not everyone responds to them in the same way. 'Larks' and 'owls' respond differently to these cues, 'owls' displaying a lag in response to these cues, for lack of a better term.

There is interesting genetic research which seems to indicate that these 'morningness' and 'eveningness' tendencies are actually a result of genetic differences in individuals. So then the question becomes, is the increased disease risk a result of this genetic difference?

Anyway, it is a fascinating are of study, and I'm gratified that health care is FINALLY recognizing what aviation terms 'human factors' as a workplace issue that must be addressed.

While owls and larks have different hormonal schedules, they respond to the environmental cues in the same way in terms of setting their circadian clocks, larks tend to experience peak melatonin production between 3 and 4 am, while owls tend to have peak melatonin production around 5-6 am, being awake or exposed to light, particularly blue waveform light, for even short periods during these times will drastically reduce melatonin production for both groups.

It's an indirect result of this genetic difference. It's not the genetic difference itself, but the effect on hormone (mainly melatonin) production. Melatonin production has been positively correlated to cancer risk in multiple studies and both owls and larks suffer from significantly decreased melatonin production. At least one study has looked at cancer rate in night shift workers in terms of owls and larks, and while it found a small increase in the risk for larks, it was not statistically significant.

Thanks everyone for their input; its very helpful. :) I think with less stress and better eating it may work out well for me. I feel tired a lot right now, so I can't see that getting worse, only maybe better. And maybe I will be able to see my boyfriend more, by the time I get home from work now, take a shower, cook dinner, walk my dog, its already 8 or 9 pm so we hardly see each other (we don't live together). If on night shift I'll be up an hour before he even gets back from work. Also, because of the pay increase I'll be able to work 4 days instead of 5, which would be nice..

You get to work eight-hour nights? Lucky ducky!

Nights is an entirely different mindset- I love nights, and hope you do too!
