The main way a salt lamp contributes to a better night's sleep is through the light it gives off. The pink-red colour of the salt diffuses the light into a soft glow that mimics the sunset and helps you unwind. Unlike blue light given off by electronic devices, warm-coloured light is conducive to relaxing and sleep. Himalayan salt lamps supposedly produce negatively charged ions while water molecules from the air attract to -- and then evaporate from -- the warmth of its surface. Those who believe in the health benefits of these lamps give negative ions much of the credit.
