Two breathing techniques are explained in this video:

1. Long Deep Breathing: The goal is to breathe in deeply through your nose, allowing your belly to expand, and then exhale slowly through your nose or mouth. The key is to make each breath as deep and full as possible, focusing on your inhales and exhales equally. Long deep breathing is a great technique for calming the mind and reducing stress. By slowing down your breath, you can slow down your heart rate and bring your body into a more relaxed state. This can be particularly helpful when you're feeling anxious or overwhelmed. You can practice long deep breathing anytime, anywhere, and for as long as you'd like.
   
   
2. Breath of Fire: A more intense technique that involves rapid, forceful breathing through the nose to clear the mind, boost energy levels, and improve lung function. It's important to note that breath of fire may not be suitable for everyone, and if you have any respiratory issues or concerns, it's best to consult with a healthcare provider before trying it.
