Infrared light is not directly associated with cancer cause. However, speaking of skin cancer, it can promote the cancer agents already present in your skin by overheating the body surface. Likewise, the IR light can lead to cataract formation with direct exposure. All in all, it is your stable health condition and precautionary steps that matter a lot. Some of you may think that far IR light is safe and doesn’t require much attention towards safety. However, that’s not the fact. You should equally consider taking safety measures, whether under far IR light or spot heating.
