What is the difference between cortisol and adrenaline?

Cortisol and adrenaline are both hormones produced by the adrenal glands, but they have different functions and effects on the body.

1. Cortisol:
- Cortisol is often referred to as the "stress hormone" because it is released in response to stress and helps the body cope with stress.
- It plays a role in regulating metabolism, immune response, and blood pressure.
- Cortisol helps the body maintain energy levels during times of stress by increasing blood sugar levels and breaking down fats and proteins for energy.
- It also has anti-inflammatory effects and helps the body recover from stress.
- Cortisol levels tend to be higher in the morning and decrease throughout the day.

2. Adrenaline (Epinephrine):
- Adrenaline is often referred to as the "fight or flight" hormone because it is released in response to stress or danger and prepares the body for action.
- It increases heart rate, blood pressure, and blood flow to muscles, providing the body with the energy and oxygen needed to respond to a stressful situation.
- Adrenaline also dilates airways, increases breathing rate, and releases glucose into the bloodstream for quick energy.
- It helps the body react quickly to a threat or danger and can improve physical performance in stressful situations.
- Adrenaline levels can rise rapidly in response to stress or danger and then decrease once the threat has passed.

In summary, cortisol helps the body cope with and recover from stress, while adrenaline prepares the body for action in response to stress or danger. Both hormones play important roles in the body's stress response system.
