Deep breathing is a simple but effective method of relaxation.
It is a core component of yoga and Zen meditation. Many people spend much of their time breathing very shallowly, filling only the upper part of their chest with air.
This shallow breathing limits the amount of oxygen that your body takes in, and it can also make you feel very anxious in times of stress. By contrast, deep breathing can decrease stress, lower your blood pressure, and slow your heart rate.
It’s easy to start practicing deep breathing techniques. All you need to do is sit comfortably, take a slow, deep breath in through your nose, and focus on what feels like filling your lower belly with air.
