Some of the common physical signs of stress include headaches, dizziness, muscle tension or pain (especially in the shoulders, neck, and back), jaw clenching and teeth grinding, chest pain or a feeling of increased heart rate, shortness of breath, fatigue, changes in sleep patterns (either sleeping more or less), upset stomach including nausea, diarrhea or constipation, dry mouth, hair loss, and changes in sexual desire or ability. Stress can also cause respiratory distress signs like faster breathing, skin color changes, nasal flaring, sweating, and difficulty breathing in severe cases. Other physical manifestations can include sweating, changes in appetite, rashes or itchy skin, and digestive problems such as heartburn or stomach aches.
These physical symptoms arise as the body's stress response activates hormones and nervous system reactions, impacting various body systems. Chronic stress can exacerbate or lead to more serious health problems if not addressed.
