The adrenal gland, located on top of your kidneys, produces two fear hormones: adrenaline and cortisol. These hormones are released into your bloodstream, affecting various parts of your body.
- Adrenaline is also known as epinephrine and is associated with the "fight-or-flight" response. It increases your heart rate, blood pressure, and respiration, providing you with the energy needed to react to a perceived threat.
- Cortisol is known as the stress hormone. It helps your body cope with stress, but prolonged exposure can have negative effects. It increases blood sugar, suppresses the immune system, and can lead to anxiety and depression.
Both adrenaline and cortisol play a crucial role in the fear response, preparing your body to deal with dangerous situations.
