Why do pupils dilate in the fight or flight response?
Pupils dilate in the fight or flight response to allow more light to enter the eyes, helping to improve vision and awareness in dangerous situations.
How do the fight or flight response affect the dilation of pupils in a stressful situation?
In a stressful situation, the fight or flight response triggers the release of adrenaline, which causes the pupils to dilate. This allows more light to enter the eyes, helping to improve vision and awareness in order to better respond to the perceived threat.
What dilates in the fight- or-flight response?
During the fight-or-flight response, several physiological changes occur, including the dilation of the pupils and bronchioles in the lungs. This dilation enhances vision and increases airflow, allowing for improved oxygen intake to support heightened physical activity. Additionally, blood vessels in the muscles may dilate to increase blood flow, providing the necessary energy for a quick response to threats.
What can cause you to lose sight when nervous?
When a person feels nervous, the body activates the fight-or-flight response, which can lead to physiological changes such as increased heart rate and shallow breathing. This response may reduce blood flow to the brain and eyes, causing temporary vision disturbances like blurriness or tunnel vision. Additionally, hyperventilation can lead to a decrease in carbon dioxide levels in the blood, further affecting vision. Stress and anxiety can also distract the mind, making it difficult to focus visually.
