Good afternoon. I agree with the previous answer. There is no point in worrying about the level of this or that hormone. You will get tired of taking medications, treating sympotamitics is the last thing.
The cause must be eliminated. Namely, through the correct angle of view on life. Recognize that there are tons of things that are not in our sphere of influence and focus on your circle of influence. Which is always wider than you think .
And over time it will only grow wider. Start with what you can change right now. In my life. It's a little better to start eating, get a little more rest, and strain less over every little thing, and so on. A step-by-step solution to stress problems is the surest.
Good morning! I will answer from the point of view of psychosomatics and energy psychology, cortisol is the body's response to stress (but not only, but also dysfunction of the adrenal glands). But I will answer precisely from the point of view of stress, because this is an epidemic of the modern world - a colossal load on the nervous system.
In order to normalize cortisol levels, you need to slowly but surely get rid of the habit of worrying, worrying and fearing what is not under your control. It sounds very simple, in fact it is very difficult. But it might depend on how much you want to change your mindset.
