How can anxiety lead to numbness in the chest?

When you feel anxious, your brain sends signals that trigger the body's natural "fight or flight" response. This response makes you breathe faster, a reaction called hyperventilation, which can upset the balance of oxygen and carbon dioxide in your body. This imbalance might lead to numbness or tingling sensations in your chest. Anxiety also can make your chest muscles and other parts of your body stiff and tense. Muscles that are too tight can press on nerves or change the flow of blood, which sometimes makes a part of your chest feel numb. These symptoms are usually not a sign of a heart problem but are instead due to your body’s stress response. Simple relaxation techniques like taking deep breaths or finding a quiet moment may help calm your body and reduce these symptoms. If these feelings become stronger or cause worry, it is important to seek advice from a healthcare professional to be sure everything is alright.
