Stop walking on your hands Dessie
found the explanation below on yahoo answers

In your body, there are two main "compartments" of fluid. The fluid that is in your tissues such as skin, muscles, organs..etc and the fluid that is in the blood. Fluid is continuously moving between the two compartments. There is a balance in this fluid movement to make sure that too much does not move in one direction. If too much moves towards the tissues, then you have swelling of the tissues. If too much moves into the blood, then you have almost no skin tightness (turgor).

To simplify things, the things that control the net movement of fluid between the compartments are:

1. Proteins and salts in the blood (pulls the water back from the tissues due to the osmotic gradient)
2. Proteins and salts in the tissues (pulls water into the tissues from the blood)
3. Blood pressure (pushes water into the tissues)

If these are altered, then you get a shift of fluid from one compartment to the other.
e.g.
if the blood pressure increases then more fluid moves into the tissues than moving out.
if you have less proteins and salts in the blood, then more fluid moves into the tissues than moving out.
if you have too much protein and salt in the tissues, then more fluid will again move into the tissues than moving out.

When you exercise, you will have a higher blood pressure because the heart is pumping much harder to get more blood around the body. This higher blood pressure may increase the amount of fluid that is moving into the tissues. Furthermore, when you sweat, you lose salts. Fewer salts in the body may also lead to more fluid moving out of the blood and into the tissues. Furthermore, the blood vessels tend to dilate in order to lose heat, this causes a higher surface area inside the blood vessel which may increase the diffusion out of the blood. Why this occurs in some people and not others may be related to disease (high BP and low proteins and salts in blood), or it may be related to the poor circulation (Blood moves out of the limbs and back to the heart slower than blood going to the arms causing a "traffic jam" and increasing the "local blood pressure"), and in some people, it is normal and may be related to just the way their body is built.
