Why raise the bed six inches at the head end for Inclined Therapy?

An experiment was performed to determine the optimum angle for circulation.

Using a closed water filled loop of tubing with coloured salt solution added at the pillow end and the loop stretched down the bed, the bed was elevated.

The lower elevations in the range of 4-4.5 inches resulted in the salt flowing down one side and the clean water flowing back up the same side. 2 directional flow in one tube while fascinating to watch was not the desired effect.

After raising the bed to 5 inches the downward flow was in the salt added side representing the arteries and the return flow was in the opposite salt-free side representing the venous return or indeed the return flow of the cerebrospinal fluid system or the return flow of the lymphatic system.

this return flow and return is under tension and was observed using soft walled silicon tubing showing clearly how the solutes affect the pressure of the water molecules.

The downward flowing side clearly bulged outwards under the positive pressure induced by gravity, while the return flow water only side was pulled in, indicating that the molecules were placed under tension by the gravity affect on the salt dissolved in water.

Over time this has been born out by many people sleeping inclined, while a 4 inch incline is better than sleeping flat, a 6 inch / 15 cm raise producing a five degree to the horizontal on a 75 inch long bed.

Fascinating history of the bed reveals that the oldest beds know from the ancient Egyptians some 4 thousand years ago were raised by exactly 6 inches at the head end according to a curator of a museum in Boston. USA.

Question is how did they know? Did they observe animals sleeping on an incline and imitated them and then find the benefits? We will never know but it is intriguing.

In 2006, Laura Lawes was diagnosed with Multiple Scelrosis and given a life expectancy of one year. Three years later, she was not only living strong, but she gave birth to her first son. It was called "a miracle birth". These miracles are possible today, because of the work organizations, such as yourself, have done. Here, at (a website dedicated to disease preventions and treatments) we are inspired by stories such as this, and would like to join you in fighting this cause. If you could, please list us as a resource or host our social book mark button, it would be much appreciated. Lets create more of these miracles; together.If you want more information on that please email me back with the subject line as your URL.

Hi Lisa

Tried to email you but your website url does not respond, says you need to alter your settings to allow this.

A new group has been set up to discuss the merits of sleeping Inclined by raising the head of the bed six inches or 15 cm’s.

16 years of research have provided us with concrete evidence that the human body benefits from avoiding flat bed rest! This is achieved by raising the head end of the bed 6 inches or 15 cm’s and is called Inclined Therapy. (I.T.) Hope you will join our group.

We are seeing some convincing reports from people with ms trying I.T here on Thisisms forum:
A Poll is conducted here asking about a connection with varicose veins and CCSVI in ms.
I.T. helping people with spinal cord injury on Youtube:

Thanks for taking the time to read this.

Fascinating post, but I felt I was missing a punchline: "while a 4 inch incline is better than sleeping flat, a 6 inch / 15 cm raise producing a five degree to the horizontal on a 75 inch long bed..." what do the crucial extra 2 inches do! And is the nature of the desirable flow dependent on the diameter of the tube (blood vessel) or only on the angle of inclination?

Hello Andrew,
I sleep with an incline of 10inches,feels natural.
You suggest 6 inches.
Is 10 inches to high ?

Thanks in advance, Jan Rozendaal
