Your head needs to drain well.

Oxygenated blood is pumped into your head by your heart. Once in your head, some of this blood passes through filters to form a specialised fluid that bathes and supports your brain and spinal cord. This fluid is called cerebrospinal fluid.

When the blood in your head has been used up and needs to return to the lungs for re-oxygenation. To do this it relies on clear channels of drainage to leave your head freely. There is nothing in your head pumping the blood back out.

If the channels of drainage in your head are restricted it can lead to a build up of pressure in your head. This can puts pressure on your brain. That pressure can manifest as a feeling of your head being continually overfull.

Also because the blood is not leaving your head as quickly as it should it can cause feelings of vagueness or a fuzzy quality in your head. This happens because your head is full of slightly stagnant blood all the time.

The channels of drainage from your head are part of the craniosacral system. Some of these channels are minute. Finding restrictions and assisting them to release can substantially improve the drainage of blood from the head.

See this case history for a good example of the effects of restricted drainage. A 32 year old woman diagnosed with Benign Intracranial Tension, at high risk of having a stroke and scheduled for urgent surgery.
