Very complete list of possibilities for those with sleep problems.
In the US, the Chemical Catastrophes are probably a bigger player than elsewhere in the world. We have more UPF's containing neurotoxic chemicals that affect our brain metabolism, including our sleep cycles. Whenever I inadvertently eat something with chemicals in it, I fall asleep early, wake up in the middle of the night, then can't get back to sleep, followed by a headache in the morning.
