How Stress Appears Across Nearly Every Body System
Stress is not only a feeling in your mind; it can affect your whole body.
When you feel stressed, your brain tells your body to prepare for danger.
This can make your muscles tighten and cause headaches or back pain.
Stress can also upset your stomach and change how much you want to eat.
Your heart may beat faster, and you may feel chest tightness or have trouble breathing.
A stressed mind can make it harder to fall asleep or stay asleep.
Poor sleep can leave you tired during the day.
Long-lasting stress may also make it harder for your body to fight common infections.
Chronic stress can keep muscles tense, contributing to headaches, neck pain, and backaches.
Stress can disrupt digestion, causing heartburn, cramps, nausea, and appetite changes.
Adrenaline and cortisol may increase heart rate and blood pressure during stressful situations.
Stress can also cause chest tightness and shortness of breath.
Prolonged psychological pressure may interfere with sleep, causing fatigue and weakening immune defenses.
