A moderate intensity exercise session increases your cortisol 2-4X (that’s a HUGE increase - we’re talking a doubling to quadrupling of your cortisol levels relative to baseline & often more than 1-3min cold BTW).

Also, it’s fine to exercise later in the day - that big cortisol surge subsides within a few hours after
A hard that is a moderate to highintensity exercise session has been shown to triple or quadruple your cortisol levels when it comes later in the day or in the evening.

when it comes to exercise specifically it's a stressor exercise is a stressor makes sense that it would increase your cortisol
