Any breathing activities where your breathing pattern is deliberately controlled are called breathwork. This covers a wide range of diverse approaches altogether.
The parasympathetic nervous system, sometimes referred to as the rest-and-digest nervous system, is activated when you have control over your breathing. This aids in bodily and mental relaxation, lowering stress hormones and alleviating anxious sensations. Many therapists and medical professionals advise breathing exercises for people who experience persistent stress and anxiety.
Try Square Breathing

Square breathing is yet another effective method for reducing tension and anxiety and promoting relaxation. Additionally, it can be used as a treatment for chronic obstructive pulmonary disease and to increase attention and concentration (COPD). This is how you do it:
First, allow all the oxygen out of your body by exhaling through your lips. Inhale slowly through your nose while reciting the number four. Imagine one of a square's sides for each instant. Hold your breath for four seconds while visualizing a rectangle with one second on each side. Exhale for four counts while once more picturing the yard. At least three more times should be done, or until you feel better.
Alternate Nostril Breathing

At first, this breathwork approach can seem weird. This is the procedure. Lie back in a comfortable position and let out a long breath. To seal your right nostril, use your thumb on the right side. Using your left nostril, take a breath.
Now shut your left nostril with your right hand's index and middle fingers. Use your right nostril to exhale. Use your right nostril for breathing in. To seal your right nostril, use your thumb on the right side. Use your left nostril to exhale. Keep going for a minimum of five minutes.
Practice Breathing Under Stress

Stress may quickly develop into a problem in several ways. Heart disease is one of several ill-health disorders connected to chronic stress. Take control of your focus. Use the breathing exercises mentioned above and other strategies to relax and de-stress.
At the same time, talking to someone could be helpful if you have been dealing with tension and worry for some time. Speak with a specialist. We could all use a little assistance from time to time, and a professional can provide you with various ways and advice to reduce your stress or anxiety so you may live the life you desire.
