Body fatigue & middle-of-the-night insomnia

Today was a very lazy Sunday. I’m aching all over! Mostly, my legs are stiff and my arms feel heavy. A few days ago my legs were stiff and my shoulders were screaming from trying a different kind of push-ups. So today I woke up several times during the night and the morning, and finally got up late after “third sleep”.

Be that a coincidence or not, yesterday evening I read articles about biphasic sleep. For millennia and up until the Industrial Revolution such a sleep pattern (the kind where nighttime sleep is split into two segments) was the common pattern: people would fall asleep some time after dark for two to four hours, wake up refreshed for a few hours to do stuff, and go back to sleep for a few more hours until around dawn. (I enjoyed reading about this subject particularly in this BBC article.)

I am reassured there is an explanation to the middle-of-the-night insomnia, although it makes me angry that our society prefers to shame us into thinking it’s wrong and against the interests of how we’ve organised the school and work lives of our fellow humanlings and humans.

As to what is causing my body fatigue, I am not sure. Nothing obvious, that is. I went from no exercise to daily exercise but that was 3 years ago. There was a time period where my daily exercising average was over the top (nearly 3 hours every day on average) but right now it’s been about 90 minutes every day on average for about a year.

Screenshot of the Health app showing the exercise minutes between september 2022 and september 2023: Gradual decrease from 125 minutes per day on average in September 2022 to about 60 in January 2023, then rather stable around 70 until August 2023 where the bar goes over 100. Daily average for the period rounded to 86 minutes per day.

It could be a combination of the heatwaves we’ve been having these past few months (hot nights never under 24°C/75F and blazingly hot days in the range of 30-35°C/86-95F which feels like way more given the humidity), and some intense workouts.

This week for example I discovered a particularly wicked 10-minute “functional strength” total body workout by Greg Cook on Fitness+ that is done only with body weight which killed me! Squats where you never fully stand up between each repetition, walkout pushups, and lateral lunges. This week I also rode my bike as far as its battery could take me (with the hills to climb, that’s about 65 km/40 mi).

Could be that work is stressful (and has been a kind of different stressful for about a year) and adding this to the mix probably explains the fatigue.
