Do you suffer from tension headaches or migraines? This may be a clear sign to take a step back. Muscle tension in the neck, shoulders and upper back can lead to these chronic headaches, meaning that your muscles are "on guard" against stressors.
Stress also affects your respiratory system. If you've ever had a panic attack then you know what hyperventilating, or rapid breath, feels like. This type of breathing can also be due to physical stress, like exercise. When you get dizzy during your workout it's because your body can't push oxygenated blood cells to your brain quickly enough to keep up with what you're demanding of it.
When presented with acute stress, your fight-or-flight response kicks in. You feel the sudden rush of adrenaline and a rapid heartbeat, but this all dissipates once the situation has passed. Conversely, chronic stress can lead to real lasting damage to the heart. The roller coaster of heart rate, stress hormones and blood pressure increases your risk of hypertension, heart attack, and even stroke.
The old expression "trust your gut" isn't just a saying. Your stomach has over 100 million neurons lining it that are often referred to as the "Little Brain." This network of cells communicates with your actual brain via the vagus nerve. When you're presented with a dangerous or uncomfortable situation, blood is redirected from your gut to your muscles (giving you that flushed feeling), and the "butterflies" are your stomach's reaction to that shift. If stress is very severe, it can cause vomiting, bloating, nausea and pain. It may also affect your digestion, leading to bowel issues, especially if you suffer from IBS, IBD, or Crohn's Disease.
