Pink Himalayan salt lamps: Alleged benefits and evidence
This article will focus on pink Himalayan salt lamps and whether or not there is any truth to the health claims surrounding them.
What are pink Himalayan salt lamps?
These lamps are made of chunks of pink Himalayan salt. The salt has a carved-out center in which to place a light bulb or heat source.
Pink Himalayan salt is a salt rock crystal that comes from the Himalaya Mountains in Asia. True Himalayan salt mostly comes from the Khewra Salt Mine in Pakistan.
The pink color of Himalayan salt is reportedly due to a high concentration of minerals.
Himalayan salt lamps have gained popularity over recent years and often appear in spas and home décor magazines. They are widely available to purchase for use in the home.
Many people claim that salt lamps purify the air of a person’s home or office. This is specifically useful to those with allergies to dust, insect droppings, animal dander, or other environmental allergies.
Salt lamps may also benefit people with respiratory problems, such as asthma.
However, there is little evidence to suggest that salt lamps remove allergens or germs from the air. Additionally, there is no concrete proof that salt lamps improve air quality.
Ease respiratory symptoms
Another major claim from salt lamp makers is that these products help reduce respiratory symptoms in those with asthma or chronic obstructive pulmonary disease (COPD). This is due in part to the salt lamp’s ability to remove irritants.
Not only can a person use a salt lamp, but they can also purchase a Himalayan salt inhaler online or at a drug store.
The notion of inhaling Himalayan salt comes from the ancient practice of halotherapy, in which people with asthma would spend time in salt caves. Apparently, breathing in tiny salt particles can help clear the airways and break down mucus.
There are some studies that look at the effectiveness of salt therapy for asthma and COPD, but they are not high-quality. More research is needed to say whether or not halotherapy is effective, but the practice does not seem to be harmful.
Improved mood and sleep
There are also many claims that salt lamps can improve a person’s mood or help them sleep better.
The results of one 2010 study claim that, in animals, exposure to a salt lamp for 14 weeks improved tryptophan and serotonin metabolism, leading to an antidepressant effect. The chemicals tryptophan and serotonin help regulate mood in the body.
However, an analysis of studies in humans found that there was no consistent relationship between negative or positive ionization and mood or sleep.
There is not much research into the relationship between salt lamps and sleep that have to do with air ionization or air purification.
The more likely reasons that salt lamps might improve sleep is that they give off a dim, mood-enhancing light, which might promote relaxation.
Salt lamps are unlikely to make a significant positive impact on a person’s health, but there are other reasons why a person might want to use one.
Benefits can include:
- Decorating the home. These lamps have a unique look and may complement the décor of one’s home.
- Boosting mood. The dim, pinkish light can help create a soothing atmosphere that promotes relaxation.
- Using as a nightlight. This dim lighting can help replace brighter lights at home in the evening, making it easier to fall asleep.
All of these benefits can reduce stress by helping a person spend a few relaxing moments gazing at the soft light of the salt lamp.
Are they safe?
There does not seem to be any research into the safety of salt lamps. They appear to be safe to use overall.
However, it is a good idea to keep salt lamps out of reach of children and pets.
While pink Himalayan salt lamps are nice to look at, they probably do not offer any substantial health benefits beyond helping people relax.
There is little to no evidence to back up claims of air purification, respiratory health, or mood and sleep benefits from salt lamps. Therefore, these claims need further research.
Regardless, a pink Himalayan salt lamp can provide a nice ambiance to a person’s home or office.
