Performing 2-3 diaphragmatic breaths upon waking, in the afternoon, or evening can encourage lymphatic drainage.

“diaphragmatic breathing is so useful for encouraging lymph drainage and lymph flow is because when you do diaphragmatic breathing, which is having your belly extend as you inhale, so you have this thing called the diaphragm, which is a muscle inside your body, and when you inhale, the diaphragm moves down. Of course, the lungs inflate, and ideally, your belly moves out a little bit, right? We generally tell people that it's not so good to breathe by lifting your chest and using your ribs, although you can use the muscles between your ribs, the intercostals, and your ribs to breathe, but you don't want to be breathing like this. Ideally, diaphragmatic breathing is what you do most of the time, unless you need to breathe much harder and you're inhaling... and your belly's moving out, okay? When you inhale and your belly's moving out, you are certain that you're doing diaphragmatic breathing. Diaphragmatic breathing creates a pressure differential between this cisterna chyli, right, this reservoir of lymph, and your blood supply, which has a different pressure within it.”

“And it actually can make a cosmetic difference. It can actually make a real difference in terms of less swelling of your lower body tissues, because as you clear the cisterna chyli, you allow the lymph coming up from your legs, and from other locations, to also move up, right? Because you're just creating room for it to move into those now empty tubes.”
