šļø ELEVATED AC MAGNETIC FIELDS IN MEDICAL AIR MATTRESSES
A recent assessment revealed elevated AC magnetic field levels on a clientās pressure-relief air mattressāa common medical device used for bedsore prevention.
The Finding:
While these therapeutic mattresses provide important health benefits, the electric pump and control systems can generate significant AC magnetic fields right where we sleep.
The Standard:
Building Biology practitioners recommend maximum exposure of 1 mG in sleeping areas. This precautionary guideline recognizes that we spend 6-8 hours in our beds, making it our longest single-location exposure period.
For EMF-Sensitive Individuals:
This client experiences electromagnetic hypersensitivity, making even low-level exposures problematic. While the mattress serves a medical purpose, the constant AC magnetic field exposure during sleep presented a challenging situation.
Medical necessity sometimes requires accepting certain exposuresābut understanding the trade-offs helps us make informed decisions about our indoor environment.
š Professional assessment helps identify sources and explore practical solutions.
