This is what stress can do to you.
Signs and symptoms of chronic stress can include: irritability, which can be extreme. Fatigue, headaches, difficulty concentrating or an inability to do so; rapid heartbeat, disorganized thoughts, difficulty sleeping. You can experience digestive problems, changes in appetite. Stress can also affect the way food moves through your body, leading to diarrhea or constipation. You might also experience nausea, vomiting, or a stomach ache.
Your muscles tense up to protect themselves from injury when you’re stressed. They tend to release again once you relax, but if you’re constantly under stress; your muscles may not get the chance to relax. Tight muscles cause headaches, back and shoulder pain, and body aches. Over time, this can set off an unhealthy cycle as you stop exercising and turn to pain medication for relief.
