Himalayan salt candles are made from pink Himalayan salt blocks, with a space inside to place a tea light candle. These candles provide soft lighting and a calming atmosphere
The salt is hygroscopic—it absorbs water vapor which may carry dust, pollen, smoke, mold spores etc. When heated, the salt evaporates moisture, leaving behind those particles, and supposedly cleans the air.
Negative Ion Emission & Mood /Wellbeing
When the salt is heated (by candle/light), negative ions are claimed to be released. Negative ions are often associated with feeling refreshed (similar to being near waterfalls, forests) and can help counteract effects of positive ions (from electronics, etc.). Some claim this improves mood, reduces stress, helps with relaxation.
Better Sleep, Reduced Anxiety / Stress
The soft warm glow is relaxing, reducing harsh lighting before bedtime. The idea is that dim, warm light helps the body wind down, reduces stimulation, helps with insomnia. Also, by improving mood/reducing stress, overall sleep quality may improve.
Relief for Respiratory Issues
Some say that salt candles/lamps help alleviate symptoms of allergies, asthma, or congestion by reducing irritant particles in the air, or via inhalation of minute salt particles. Also linked to the practice of halotherapy (salt therapy) in salt caves.
