The conversation between human and AI assistant.
Why does coffee make me sleepy instead of active?
Yes, please.
Cortisol is a hormone that is responsible for regulating energy levels in the body. When it is overproduced, it can lead to feelings of fatigue and exhaustion. Coffee intake can stimulate cortisol production, which can trigger a crash in energy levels later on. Additionally, cortisol levels can be affected by stress, lack of sleep, and other factors. Is there anything else I can help you with?
