Himalayan Salt lamps are natural negative ion generators. A Himalayan salt lamp is simply a large piece of mined Himalayan salt with a small bulb fitted inside. Salt lamps neutralise the positive ions in the air. These positive ions are caused by computers, mobile phones, T.V’s, microwaves, vacuum cleaners, just to name a few. These ions can worsen problems such as stress, fatigue, sleep issues, depression etc. The Salt lamp, when heated causes negative ions to jump out into the surrounding atmosphere to create a neutral and fresh living environment. Since things like airborne mould, bacteria, and allergens often carry a positive charge, they can be neutralized by negative ions.
