It depends on how much you believe on the vastu principals. Vastu works with the 5 elements of the nature namely Earth, Water, Fire, Air and Space and as our body is also made of these elements I believe that there would be a close relationship between the vastu phenomenon and our body's activities.

Vastu  not only has recommendation for the location of a flat, but it also has  recommendations on the arrangements of the objects within a flat. So if you already have a flat you could use these principals to align the objects in your home such as to produce a positive effect.

Again, as excess of every thing is not good, I won't suggest you go overboard with it :)
