Can cold showers directly lower cortisol levels?

Cold showers do not directly lower cortisol levels. The adrenal glands are not overworked in humans as they are in animals, and exposure to cold does not harm the body in this context. Therefore, there is no significant negative impact from taking cold showers.

This is one answer. The complete system — the psychology, the biology, and the method — is in the book.
