Somebody posted on GLP about waking up at 4 AM and was asking others, and a lot of people replied that they did also. I did also and have been many times recently. What about you guys? In the past, waking up before 8 AM was a rare thing, maybe once in a quarter or something.
I think this is being caused by minor space weather. There have been M class flares almost every day for weeks. Normally I see about one of those every week or two on the suspicious observers app. I've had the app for years.
Interesting theory about flares. Fact is waking in the middle of the night is natural. It's from the vast majority of humanities evolutionary path we didn't have artificial light.
What's unnatural is staring at screens until you pass out from exhaustion. Most every case of insomnia is bullshit. If you got other problems then go to the doctor cuz small chance it something could be going on. Waking up is nothing to be concerned about
