Salt lamp

Himalayan salt lamps are crystals carved from amber-colored rock salt, hollowed out to fit a lightbulb inside. When you light them, they give out a warm, reddish-pink glow. The lamps can boost mood, improve sleep, ease allergies, help people with asthma breathe better, and clean the air, among other benefits. They feel more refreshed and clear-headed after a storm, a feeling they believe is due to the amount of negative ions in the air. Commercial ionizers and purification systems also produce negatively charged ions to create cleaner and more comfortable indoor spaces.
