When the brain perceives threat, it activates the stress system. Heart rate increases, breathing becomes shallow, muscles tighten, and blood flow shifts. This is why anxiety can feel like chest tightness, palpitations, breathlessness, dizziness, stomach upset, headaches, and disturbed sleep.
These symptoms are real and measurable.
They come from changes in the nervous system, hormones, and muscle tension — not imagination or weakness.
Understanding the biology reduces fear.
Your body is responding to stress, not failing you.
With the right tools and support, the nervous system can relearn safety.
