Hospitals use blue and green light for healing purposes, as these colors have been found to offer various therapeutic benefits. Blue light is often used for its antimicrobial properties, while green light is known for its calming effects and potential to reduce pain.
Why Is Blue Light Used in Hospitals?
Blue light is a popular choice in medical settings due to its antimicrobial properties. It can effectively kill certain bacteria and is often used in treating jaundice in newborns. The therapeutic benefits of blue light include:
- Antimicrobial effects: Blue light can help reduce the risk of infection by targeting bacteria on surfaces and skin.
- Treatment of jaundice: Phototherapy with blue light is a common treatment for neonatal jaundice, helping to break down excess bilirubin in the blood.
How Does Blue Light Therapy Work?
Blue light therapy involves exposing the skin to a specific wavelength of light, typically around 415 nm. This wavelength is effective in penetrating the skin and targeting bacteria without causing harm to surrounding tissues. In the case of jaundice, blue light helps convert bilirubin into a form that can be easily excreted by the body.
What Are the Benefits of Green Light in Hospitals?
Green light is often used in hospitals for its calming and pain-relieving properties. It can help create a soothing environment for patients and may assist in pain management. The benefits of using green light include:
- Stress reduction: Green light can help lower stress levels, promoting a more relaxed state.
- Pain relief: Some studies suggest that exposure to green light can reduce pain intensity, particularly for conditions like migraines.
How Is Green Light Therapy Administered?
Green light therapy is typically administered through LED lamps or panels that emit light at a wavelength of around 520 nm. Patients may be exposed to green light in a controlled setting to achieve therapeutic effects, such as reducing anxiety or alleviating pain.
