Light waves are a particular part of the radiating electromagnetic family. In the field of medicine, light waves can also be used as a treatment for certain conditions.
Light waves are divided into various types, including radio and micro waves, visible light, infrared, x-rays, gamma rays, and ultraviolet. However, the most common use of light waves in medical treatment is lasers, which have a special role to cut, burn, or destroy tissue.
Utilization of Light in the Medical World
Light therapy is generally intended for people with seasonal depression or we are familiar with SAD (seasonal affective disorder). This type of depression is a condition when a person experiences depression during certain seasons, especially during winter.
To overcome this depression, use treatment using artificial light sources. This therapy is done to replace someone’s lack of sun exposure, considering that SAD syndrome is considered to be associated with lack of sunlight exposure.
In addition, light waves are also used to overcome various other medical conditions, including:
Overcoming skin diseases
A study shows that when exposed to light the body will experience an increase in a series of hormones called glucocorticoids. These hormones are responsible for various processes in the body, including metabolism, responses to stress, inflammation, and the immune system. Light therapy can help increase the body’s metabolism, although it still needs further research.
Light therapy is often also used to improve certain skin conditions. For this purpose, ultraviolet light will be exposed in areas of the skin that are distracted or on the entire surface of the skin. Some skin conditions that can be helped by light therapy include psoriasis, vitiligo, acne vulgaris, skin cancer, dermatitis, and mycosis.
Light therapy is also often used as a treatment for jaundice in newborns. Phototherapy is needed to break down bilirubin into compounds that can be excreted in urine and stool. Phototherapy for jaundice uses radiation in the blue-green spectrum.
For those of you who will be doing light therapy, it is advisable to find out in advance what are the effects that might appear after treatment. Some complaints that can be experienced after light therapy are mild headaches, insomnia, aches, dry eyes and nose, and the sensation of being stung by the sun.
If you have sensitive skin, have vision problems, eye disease, or have a history of cancer, it is advisable to consult a doctor before undergoing this therapy.
Utilization of Laser Light in the Medical World
Laser is short for Light Amplification by Stimulated Emission of Radiation. The use of laser light for medical treatment has almost the same risk as conventional surgery, such as bleeding, pain, and scarring. It’s just that, the recovery time from surgery using a laser is usually faster than open surgery.
Some medical conditions that can be helped with laser light treatment are varicose veins, prostate disease, kidney stones, and a number of tumor diseases. In addition, laser therapy can also be used to improve vision during corneal surgery and repair the detached eye retina (retinal detachment). In skin care treatments, laser light is also often used.
Although it has a positive function on the health of the body, light waves which are part of electromagnetic waves also have negative effects. One of the most often cause negative effects is due to radiation. Therefore, excessive light exposure, including sunlight, is best avoided.
Light waves can be used to overcome various health problems. However, you should consult with your doctor before using light waves to treat your condition.
