If you know nothing about physiology, don' worry. Even though it took me many years to figure our what I'm about to say, I will say it in laymens terms. If you are trained in anything medical related, it will be very difficult to believe this. After learning about all the things that go wrong, it rarely occurs to the educated person that things don't go wrong per se.

So why on earth would there be any benefit to the above mentioned diseases? Instead of dealing with them individually, let's deal with them together. What all these diseases have in common is simply that the end result is that the blood flowing through the body decreases.

But why would it be beneficial for the blood to flow less? Did you ever wonder why it is that during exercise, you feel your heart beating faster? That is because the blood needs to flow more to keep up with the demands of your cells.

But what would happen if your blood flowed that fast while you are resting? In short, you would be dead pretty quickly. It is not true that the more blood flowing the better. It is true that there is an ideal amount of blood flowing based on how your cells are working.

Let's relate blood flow to how fast you breathe. First of all, breathing and blood flow are related. If you hold your breath, blood will rush to your head. That is because increased circulation has a similar effect as decreased breathing rate. The less oxygen moved through the lungs, the more that needs to be moved by the blood. The inverse is also true. If you start breathing as fast as you can, your circulation will slow down for the same reason. Eventually you will get light headed due to lack of blood, and if you keep breathing fast (assuming you don't have an asthma attack first), you will pass out. Once you are on the ground, gravity will get some blood to the head.

Here is an illustration of how this class of so-called diseases works. The pattern of stress gets the engines pumping. Your metabolism goes into anaerobic/sugar metabolism mode for quick energy. You start breathing faster and your circulation increases in anticipation of physical exertion. This discrepency between perceived and actual danger is a result of an inaccurate perception of our environment. Your cells go on your perception, since that is all they can go on. The combination of faster breathing/sugar content/faster circulation without the anticipated activity to balance the chemistry, the body's chemistry gets messed up. Low carbon dioxide is the classic result, even though this is very difficult to test for directly.

So what does your body do? Besides finding ways to slow the breathing (mucous/asthma/apnea/bronchitic/emphesema..), it finds ways to slow the circulation by placque, scarring, and holes in the heart. The disease of choice is based on age (fetus/child/adult), and genes. It's that simple.

I mentioned migraines since they are a good illustration. One mechanism to slow the circulation is to narrow blood vessels (initial event in migraines) . However, when the stress which keeps the blood vessels narrowed stops, the blood vessels relax and cause a sort of wave of blood that irritates the blood vessels themselves. If the conditions necessitating slower circulation persists, the body will find more permanent ways to keep the blood vessels more narrow like plaque(atherosclerosis)/decreased elasticity(arteriosclerosis).

Instead of dealing with these thing one by one, it is much more effective addressing the pattern that necessitates these compensation mechanisms. Notice that all these patterns include an inaccurate perception of our environment. The stress reaction is not bad. It's just bad when it is not needed.

Training with the FRTD reverses this entire pattern. You are essentially creating a need for better circulation, and your body will find a way to give it to you.The pattern is reversed in several ways. First, the precise amount of resistance isolates the diaphragmatic breathing muscles, which facilitate oxygen metabolism. That alone will help break the cycle, but the FRTD attacks it on more levels. The water acts as filter, making the air you breathe slightly low in oxygen and high in carbon dioxide. This also facilitates oxygen metabolism by what is called the Bohr effect. Third, doing the device forces your mind to relax better than anything I've tried before.

It's not that you are being fixed by some man-made technology. It's more that you are using technology to allow your natural physiology perform the way it is supposed to.
