Salt lamps are decorative pieces that are said to have many health benefits, including improved sleep, better mood, and purified air. However, there is little scientific evidence to support these claims.

Benefits

Improved mood

Some say that the negative ions produced by salt lamps can improve mood. However, older studies found no consistent effects on mood.

Improved sleep

Some say that salt lamps can help you fall asleep. However, a 2013 review found no evidence that air ionization improves sleep.

Purified air

Some say that salt lamps can remove dust, pollen, cigarette smoke, and other contaminants from the air. However, researchers say the negative ions around salt lamps aren't concentrated enough to provide noticeable health benefits.

Reduced allergy symptoms

Some say that salt lamps can relieve allergies by purifying the air. However, there is little evidence that salt lamps provide any of the claimed health benefits.

Calming atmosphere

Some say that the warm, glowing light of a salt lamp provides a relaxing and calming atmosphere.

How they work

Salt lamps are chunks of salt rock that are illuminated by electric light bulbs.

The lamps are said to ionize the air by creating negative ions.

The negative ions are said to improve some health conditions, such as increasing the flow of oxygen to the brain.
