Sleep, something that everyone loves and that many people often have to catch up on. Ever wonder why we sleep parallel to the ground? Sleeping parallel to the ground cools your mind because it is much different than sleeping with your head in the north direction, which would cut the geomagnetic field at right angles and would make it more difficult to sleep. Strong magnetic fields can affect your brain. It is much of a controversial topic because research has proven differently. During MRI's they look at the amount of magnetic field and see whether or not the person has an affect and 9/10 times the person does not unless they are experiencing claustrophobia in the MRI.
