Does the InfraBed work well in Summer? Yes it does and surprisingly it works well even with the Power OFF! The 14 layers of InfraBed comprise excellent insulation and so protection from energy influences, just like the BioBlanket layers, and so with no power you still have a perfect energy reflection envelope with the InfraBed under, BioBlanket over, and Power OFF, or quite low 20 -36 C. In these settings your kilos of A-grade Amethys still exert there subtle and infrared emanations and your body is also prompted to balance its nervous energy and this adds to your ability to rest, sleep, centre and compose yourself. The other reason to use InfraBed is that even at very low temperature Infrared Energy is ANTI-IMFLAMMATORY, and so useful for keeping well.
