This is not a bike. It really happens. If the massage simultaneously squeezes a lot of lymph towards the heart, then the volume of blood that the heart pumps increases dramatically. From this it can become bad.
The worst will be for people with heart failure. These are those who have swelling on their legs, because the heart cannot pump blood fully.
People with heart failure have to limit their salt and water to reduce their blood volume and make it easier for a weak heart to work.
Lymph
If people with heart failure squeeze a large portion of lymph into the blood, then the heart will not cope. Excess fluid can remain in the lungs, shortness of breath will appear. If you try, you can get pulmonary edema and die.
And yes, excess fluid on the hands or feet sometimes builds up due to poor lymph drainage. Then her squeeze massage.
Normally, lymph collects into a large lymphatic vessel and flows into a thick vein closer to the center of our body at the base of the neck. The lymph there mixes with venous blood and joyfully rushes to the heart.
Excess water
Usually, excess water enters the bloodstream from the intestines, and the salt eaten helps this water stay in the bloodstream.
But excess water can enter the bloodstream and from lymph. Lymph is precisely the water that lay peacefully somewhere between our cells and could not get into the blood by itself. The lymphatic vessels help to collect this water spilled between the cells and pour it into the blood.
Hypertensive patients
Much the same story happens with people who have high blood pressure. The more lymph is poured into their blood, the higher the blood pressure will be.
So do not be surprised if some of you do not want to do lymphatic drainage massage.
