Healing with ultraviolet light is a technique that has been used by people for many centuries and modern science also accepts its effectiveness. Light at different wavelengths can be used for many therapeutic purposes. In fact, concentrated beams of light or laser therapy can be used to perform surgical procedures. At lower concentration levels, light can be used to heal skin wounds, infections, and other conditions. Doctors are increasingly applying light waves to help people with different medical issues. One of these applications is ultraviolet light therapy.
Consider using these devices to get ultraviolet light therapyat home. However, make sure to check with your medical practitioner before using any devices without supervision.
What is Ultraviolet Light Therapy?
Ultraviolet light therapy is also called phototherapy or photochemotherapy. A part of natural sunlight, ultraviolet rays are a distinct band of light spectrum that is not visible. In place of just spending time in the sun, you can make use of many high-tech devices for getting ultraviolet therapy. These devices provide you with UVA and UVB rays of light. Aside from using UVA and UVB treatments, doctors also combine the therapy with medications to help with skin issues such as psoriasis, eczema, and jaundice in newborn babies. This therapy is called PUVA treatments. You may be asked to apply ointments and salves or take the medications internally in pill form.
Ultraviolet light therapy is the preferred choice of treatment for doctors. Since it has relatively fewer side effects, they would recommend that you opt for the therapy in place of other medications. While getting the therapy can have a host of positives, it does involve visiting your doctor’s clinic many times during the week during working hours. For this reason, many patients prefer other treatments that are not likely to disrupt their work and home schedules. Getting ultraviolet light therapy may also work out to be a bit expensive since insurance companies consider it as an office visit and you may be asked to co-pay for the treatment.
How Ultraviolet Light Therapy Works
Ultraviolet light therapy is known to be highly effective for many skin conditions. To give you an understanding of how ultraviolet light therapy works, let’s talk about psoriasis as an example. This skin condition is caused when the body’s immune system attacks the skin cells. As a result, they start to multiply rapidly because of which you notice redness, itching, and lesions on the skin. Ultraviolet therapy works to kill the immune cells in the skin that cause the condition. The UV light also prevents the forming of skin lesions by breaking the connections between the skin cells and immune cells. By slowing the rapid, uncontrolled growth of the skin cells, UV rays can stimulate the healing of skin infections and injuries.

How the Therapy is Given
You can get ultraviolet light therapy naturally by exposing your skin to the sun. You can also try the many devices that are available today in the privacy of your home or in a doctor’s clinic. The number of sessions you need and the time for which each session must last depends on the specific skin issue. Typically, UV therapy sessions last for a few minutes to one hour. You may be asked to come in every day or a few times each week. But, you can rest assured that these devices have carefully controlled levels of UV radiation and are not likely to hurt you. Some of them are:
- Lightboxes, light beds or walk-in cabinets that are fully-sized to accommodate an adult
- Handheld devices can be used to give UV therapy to smaller sections of the body like on the arms or legs.
