Whenever you are feeling anxious or stressed, the first thing you are told to do is control your breath. There are many different breathing techniques that you can try, like yoga breathing practices like Ujjayi breath, alternate nostril breathing, and deep diaphragmatic breathing.Diaphragmatic breathing, often called belly breathing, is a simple way to use your diaphragm muscle to breathe more effectively. The Cleveland Clinic explains that the diaphragm is a dome-shaped muscle at the bottom of your lungs. When you inhale, it moves down, making space for your lungs to fill with air. Your belly pushes out as this happens. When you exhale, the diaphragm moves up, pushing the air out. This type of breathing is different from chest breathing, where only your chest moves. You can do this breathing technique anywhere, anytime, and no one will even notice. It's a great tool for calming down quickly.Why Do You Need Breathing Exercises The reason why this is the go-to response for stressed people is because when you are stressed, your breathing becomes fast paced. The Cleveland clinic explains that stress triggers a fight or flight response in your body. Your body goes into survival mode as it thinks it is in danger. Some symptoms of this include, racing heart rate and blood pressure increase, this means that you are breathing quickly and heavily in order to move nutrients and oxygen into important muscles of your body. Benefits of Belly BreathingBelly breathing has many good things about it. It helps calm your nervous system, which is important when you're stressed. It activates a nerve called the vagus nerve, which helps your body relax. When you breathe slowly, your heart rate also slows down, and your body feels less stressed. It helps you control your feelings, like anxiety and fear, so you can think more clearly. This kind of breathing also helps your lungs work better by taking in more oxygen. It can even help you sleep better because it calms your mind. By practicing regularly, you can feel calmer and more relaxed every day.How to Practice Diaphragmatic BreathingCertain conditions like Chronic Obstructive Pulmonary Disease (COPD) do make it difficult to work the diaphragm effectively. Your lungs rise and fall naturally, however with COPD air often becomes trapped in your lungs. Make sure you speak to a healthcare professional in case you are facing any difficulties while breathing. To start, find a comfy spot. You can lie down with your knees bent or sit with your feet flat on the floor. Put one hand on your belly and the other on your chest. Now, breathe in deeply through your nose. Let your belly push out while your chest stays still. Hold your breath for a moment. Then, slowly breathe out through your nose or with your lips a little bit closed, letting your belly go back in. Do this four to six times, slowly and deeply. As you get better at it, you can do more breaths. Practice this every day, even when you're not feeling stressed, to feel calmer all the time.
