Physical & Somatic Sensations
- Increased resting heart rate
- Shallow or rapid breathing
- Chest constriction
- Restlessness and fidgeting
- Cold hands and feet
Why Do We Experience Anxiety?
Anxiety is an evolutionary alarm mechanism designed to keep you alert to potential danger, social exclusion, or environmental disruption by priming the sympathetic fight-or-flight system.
Common Causes & Triggers of Anxiety
