When I Switched to Night Shift During Perimenopause: It Was a Disaster

I agreed to switch to the night shift at work thinking it would be a temporary arrangement. An extra three months of night shifts and then I would go back to day shift. My company was offering a bonus if people would cover the night shift temporarily. I was 47 years old and I needed the money. I also thought I could handle it. I had done night shift work before, years ago when I was younger. What I did not anticipate was that I was in the middle of perimenopause and that switching to night shift during this life phase would be absolutely catastrophic for my body.

How I got here

My perimenopause had been relatively manageable up until the night shift switch. I was dealing with some hot flashes and some irregular periods and some mood shifts, but nothing that was severely impacting my life. I was managing it with lifestyle changes and some supplements. When the night shift opportunity came up, I thought, 'I can do this. It is temporary. The extra money would be helpful.' I did not consider that my circadian rhythm was already disrupted by perimenopause hormones and that throwing in a night shift was going to completely destabilize my system. I made the switch thinking it was no big deal. I was wrong.

What I actually did

Week one of night shift, my body was completely confused. I was supposed to sleep during the day and be awake at night. But my perimenopause night sweats were worse when I tried to sleep during the day. And at night, when I was supposed to be working, I was having hot flashes that made it impossible to focus. My circadian rhythm was completely disrupted. Week two, I was exhausted. I could not sleep during the day because of the night sweats. I was struggling to stay alert at night because I was so tired. My mood was completely unstable. I was snapping at people. I was crying for no reason. By week three, I was in crisis. My body was not adjusting to the night shift. Instead, I was deteriorating. My hot flashes were constant. My night sweats were worse. I was not sleeping at all, either during the day or at night. I was so tired that I was making mistakes at work. My anxiety was through the roof. I was having panic attacks at 3 a.m.

What actually changed

I realized very quickly that I could not sustain this. I talked to my manager about going back to day shift. I explained that I was going through perimenopause and that the night shift was making my symptoms unmanageable. My manager was understanding and agreed to let me switch back after just three weeks instead of the full three months. The switch back to day shift made an immediate difference. Within days, my sleep improved. My hot flashes decreased. My mood stabilized. The anxiety decreased. It was clear that for me, at this stage of my life, night shift was not compatible with my body's needs. What I learned from this experience is that perimenopause changes not just the obvious things, but also things like your capacity to handle schedule disruptions. My body needed consistency and regular sleep more than it needed the extra money.

What my routine looks like now

I am back on day shift and I am never going back to night shift during perimenopause. I realize I might lose out on opportunities that require different hours, but my health is more important than money. I have learned to be more realistic about what my body can handle during this phase. I started using PeriPlan to track my sleep and my symptoms, and I can see clearly that my symptoms are dramatically better when I have consistent sleep and a regular schedule.

If you are in perimenopause and you are considering a schedule change that involves disrupting your sleep, I would strongly suggest thinking twice before you do it. Your body needs consistency and sleep during this transition. The extra money might not be worth what it costs your health and wellbeing. What worked for me is not medical advice, and what your body needs may be completely different. Always talk to your healthcare provider about your specific situation before making major life changes. They can help you understand what is sustainable for your body during perimenopause.
