Cortisol: The Ultimate Guide
What is Cortisol?
Cortisol is a steroid hormone produced by your adrenal glands, which sit on top of your kidneys. It's often referred to as the "stress hormone" because it helps your body respond to stress.
Cortisol's Role in the Body
Cortisol plays a crucial role in regulating various bodily functions, including:
- Stress response
- Metabolism
- Immune function
- Blood sugar levels
- Energy levels
When you're under stress, your adrenal glands release cortisol into your bloodstream. This triggers a cascade of events that prepare your body for a "fight-or-flight" response. Cortisol helps you to:
- Increase your heart rate and blood pressure
- Sharpen your focus and reaction time
- Provide energy by breaking down stored glucose
- Suppress non-essential functions, such as digestion
