The Himalayan salt lamp does not purify indoor air at all.
These stylish small table lamps consist of a pink Himalayan salt and a small light bulb inside. They are hand-carved and usually have a stylized shape that glows pink when they pass through them and is easily recognizable.
In recent years, Himalayan salt lamps have become increasingly popular, with their unique colors and appearance, making them a favorite interior decoration, and the pink gleam that exudes a pleasant atmosphere.
But recently, they have become famous because of the "new identity" of "natural" air purifiers, which can be confusing.
A large number of misleading studies have shown that salt can treat respiratory diseases. These conclusions have led to an increase in the demand for Himalayan salt lamps, especially in some pharmaceutical markets. When modern medicine shows no curative effect, a large number of people are beginning to seek home therapy, hoping to improve their health and indoor environment.
However, please do not buy Himalayan salt lamps to purify the air, because they are negative ion generators, and negative ions are one of the most ridiculous air purification myths ever.
Why are Himalayan salt lamps harmful to air quality?
1 Many air purifiers and purification devices on the market, including Himalayan salt lamps and various "air ionizers", are artificially producing high voltages to achieve "purification" effects. However, negative ionization does not really remove contaminants from indoor air – it only causes contaminant particles to adhere to the surface of nearby objects and is then easily dissipated by indoor activities such as dusting, vacuuming, and ventilation. Open. Charged particles also adhere to the respiratory tract, enter the trachea and lungs and settle there, and even cause more damage if they remain suspended in the airway. Studies have shown that these particles can penetrate the respiratory system and cause heart and lung disease.
2 In general, bedside cabinet-sized Himalayan salt lamps produce only a small amount of negative ions in the air, so at least in a short period of time, you may not notice any significant changes in air quality or health. But these lights can also be very large: if you spend thousands of dollars to buy a 300-pound salt lamp, their ionization effect may have a more pronounced effect on the air, especially if you live in an indoor polluted air that is difficult to evacuate. Closed and efficient space.
What is special about Himalayan salt?
Salt lamps have been proposed for the treatment of diseases such as chronic obstructive pulmonary disease (COPD) because they are said to have a therapeutic effect on the respiratory system. There is even a clinical term for this treatment: salt therapy, based on an ancient respiratory therapy called "cave therapy." Cave therapy first appeared in Eastern Europe. The treatment consisted of staying in a salt cave for a period of time. Four environmental conditions in the salt cave were thought to help reduce the symptoms of respiratory diseases:
Medium to high humidity
Suspended particles of elements such as potassium, sodium and magnesium
Less air pollution
Salt therapy uses the concept of salt caverns to promote respiratory health. The controller releases salt particles into the surrounding air, allowing people to inhale small amounts of salt particles and “recreate” the small environment of salt caves. But neither cave therapy nor respiratory therapy, there is no conclusive evidence that they can alleviate respiratory symptoms.
There are a number of precautions you can take to monitor indoor air quality and keep indoor air clean, such as the following proven methods:
Regularly clean the HVAC system piping. Installing a full house air purification unit in a HVAC system can reduce indoor pollution by 95%.
Repair damaged areas in the home to prevent mold and dust mites.
Store chemicals such as paints and solvents in a well ventilated area.
Ventilate the home. Introduce fresh air regularly to reduce the concentration of indoor air pollutants. This is especially important for people living in confined, energy-efficient spaces. When indoor pollutants cannot be dispersed, they can accumulate to dangerous levels.
When the outdoor air quality is good, open the window and ventilate.
Use a range hood to absorb soot and volatile organic compounds (VOCs) from cooking.
