Night Sweats Experiment

Since my doctor suggested that my dizziness, fatigue, and night sweats are not due to a cardiovascular problem, I decided to do some research on the other causes of night sweats. I read an article that said that most night sweats are simply caused because the person is too warm at night. I wondered if I fell into this category before reading this article, and I tested it by pulling down the blankets before going to bed at night. I still woke up in the middle of the night with the soaking wet shirt. However, I decided to test this possibility further.

I have two sets of sheets. My summer sheets are simple cotton sheets. My winter sheets are also 100% cotton, but they are T-shirt sheets so they are thicker, softer, and warmer. I usually switch the sheets on my bed when the rest of the world changes their clocks to “spring forward” for daylight savings time or “fall back” to standard time. In the winter I usually have two blankets on my bed as well. One is a fuzzy soft blanket and the other is a heavier blanket that is crocheted using acrylic yarn. I like the weight of the heavy blanket on my body and the softness of the fuzzy blanket against my skin.

This is been a particularly warm winter in Phoenix. The high temperature during the day is often 10° above normal – in the mid- to high 70’s or low 80’s. The low at night is only in the 50’s, and my home is really well insulated. It made me wonder if sleeping with T-shirt sheets and two blankets were contributing, if not causing, my night sweats.

So this past weekend I switched out my T-shirt sheets for my summer sheets. I took the fuzzy blanket off my bed completely and I folded the heavy blanket down so that it’s only on the foot of my bed. I read somewhere that you get the best sleep when your head is cold and your feet are warm.

I wore this shirt with the cooler set up. It was still this wet 5 hours after I took it off.

When I put myself to bed the first night in my colder arrangement, I was absolutely exhausted. I thought I would have no problem falling asleep – but I was wrong. Despite being in a condo that was around 70° inside, I felt really cold. I was uncomfortably cold, so much that it made it hard to get comfortable and fall asleep. I told myself this might have to be the payoff could not have night sweats.

I was wrong about that too.

A few hours later I woke up with a soaking wet shirt. I’m pretty convinced that my night sweats are not due to being too warm at night. But at least I have evidence of this to take to my doctor when I see him later this week.
