That is textbook reversed cortisol circadian rhythm.
See, cortisol should spike in the morning (it’s actually what wakes you up when you wake up on your own). Cortisol spikes in the morning which increases the conversion of noradrenaline into adrenaline, giving you energy and drive for day.
Cortisol should be low in the evening/night (and moderate throughout the day). If you produce too much cortisol during the day, or even worse keep it elevate in the evening/night, for a while you run the risk of inverting your circadian rhythm so that cortisol is now high in the later part of the day and high in the evening, therefore it cannot be high in the morning.
I’m guessing that you will take a lot of coffee in the earlier part of the day. Caffeine will increase cortisol and the conversion of noradrenaline to adrenaline which will give you energy. But it’s a crutch for inverted circadian rhythm.
Crossfit is one of the types of training that increase cortisol the most.
First because cortisol’s main function when training is to mobilize energy. The more energy you need, the more cortisol you release. In crossfit, because of the high volume you do need to mobilize a ton of fuel, thus you spike cortisol a lot.
Second because you spike adrenaline during your workout because of the fast pace. This requirement for adrenaline makes you produce more cortisol so that you can convert more noradrenaline into adrenaline.
WHEN DO YOU TRAIN?
Because if you train in the afternoon or (even worse) evening, then you are getting a huge cortisol spike when you need cortisol to go down.
