The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.

if you then ingest carbohydrates you are telling it is quick to see the sign all we have nutrients we have energy again specifically carbohydrates therefore cortisol can sort of go back down we don't need to be liberating free fatty acids and preparing uh the need for fuel so you can help yourself go to sleep for many as you pointed out many mechanisms actually of why carbohydrates will help you sleep at night
The other thing that you can do to bring your cortisol levels down in the evening and at night time is to consume some starchy carbohydrates.
What you'll find is that eating starches in the evening will help keep your cortisol low. And guess what? It's absolutely obvious why that would be. Remember, cortisol's main job is not to deal with stress. It does that, but it's to deploy blood glucose so that you can deal, yes, with stress, but with all sorts of things in your schedule.
and then they'll come back down, especially if you're doing things to deliberately bring them down, including eating a meal laden with carbohydrates will which will help bring those uh cortisol levels down.
So, in the evening or at least for your last meal of the day, having some starches if that's within your nutritional plan is a good idea if your goal is to keep cortisol low. And guess what? Your goal should be to keep cortisol low because you want to be relaxed in the evening and be able to sleep easily.
