5 Types of Light Therapies and Their Uses


Human bodies are fragile, and the recent coronavirus outbreak has only proved it further. We have come a long way, not just because we are superior, but because we know how to take care of ourselves.

Taking good care of our bodies can prove to be significant in terms of physical and mental abilities. Not just that, but by taking care of ourselves in ways that science deems fit, we can rise above mediocrity.

That’s why today, we have come to show you ways in which you can take better care of your health – both mental and physical – that you might have even heard of before! Light therapy, also known as heliotherapy or phototherapy – uses the wavelengths of light in a controlled environment to bring out positive results.

1.     Infrared Light Therapy

We have all seen heat lamps or probably owned one at one point or another in our life. The light that comes from these heat lamps produces a kind of infrared light that radiates heat. This kind of infrared light provides some benefits that can be highly valuable for our physique:

  • It helps to cut body fat
  • Improve the body’s immunity to cancer
  • Assist the wounds heal at a faster rate
  • Relieve from pain in nerves, joints, muscles

You must use it according to your needs because different situations require different kinds of usage. For example, an infrared ray frequency of 430 terahertz with 700 to 1050 nanometer is necessary to warm babies in the neonatal intensive care unit (NICU).

2.     Red Light Therapy

A growing number of people are starting to have problems regarding sleep. As we keep surrounding ourselves with digital devices and screens, we keep on exposing ourselves to blue light emitting from these portable light therapy devices.

The blue light emitting from these digital devices trick our brains into thinking it’s daytime when it’s really not. It’s concerning for several reasons, number one being sleep disorder or deprivation.

Red light therapy promises to make up for the loss in our health from blue light exposure. It also comes with other health benefits:

  • Detoxify the body by turning on the lymphatic system
  • Repair the damage caused by sun
  • Stimulate hair growth to end baldness
  • Reduce stretch mark or pores in the skin
  • Helps you stay young by holding back the wrinkles
  • Improve the circulation of blood flow in the body

It’s easy to get distracted as there are many red lights in the market that promise to do the trick. But, in reality, those red lights do not even emit red light, rather tint the blue light of natural lights. It is indeed true that these lights will alleviate the adverse effects of blue light emission. Still, it doesn’t come with the health benefits of red lights as these products don’t emit red light in itself.

Scientists have published numerous papers regarding the Red Light Therapy, proving that it can really improve the lifestyle of an individual looking to stay healthy!

3.     UV Light Therapy

We have already seen how UV light is used in labs and other facilities to help guide doctors and scientists. It was rather a recent discovery that UV light can be used in living human bodies to help make lives better.

Even food companies are taking advantage of this breakthrough in UV Light Therapy to sterilize their food before packaging or canning. Here are the perks that UV Light Therapy can have on your body:

  • Treat skin conditions such as Atopic Dermatitis, Eczema, Cutaneous T-cell Lymphoma. Also, Acne Vulgaris, Vitiligo, Psoriasis, Pruritus
  • Improve the immune system
  • Dilate blood vessels to improve circulation
  • Helps newborn babies fight jaundice
  • Improve oxygen absorption in the body

This therapy can vary from wavelengths to wavelengths, so you should keep in mind that when the wavelengths become too short, it could turn into an x-ray as opposed to UV light.

4.     Full Spectrum Light Therapy

Sunlight is essential for us, humans, to keep up our health. It is proven from scientific research that without sunlight, people can get apathetic and depressed. Not just that, it can create a deficiency in different vital organisms in the human body.

Full Spectrum Light Therapy mimics the sunlight to produce the right amount of serotonin and melatonin in our body. Here are all the benefits:

  • Color perception in eyes amplifies
  • Strengthens teeth
  • Helps boost mental awareness
  • Helps improve mode

During the crisis of coronavirus, the whole world is at lockdown. It will be hard for people to get proper sunlight in such conditions. This could be the perfect solution for them.

5.     Blue Light Therapy

A lot of treatments of skin require that you don’t go out in the sun. If you are one of the people taking such medications and looking for an alternative, this is your lucky day! Blue Light Therapy helps treat the myriads of skin diseases without any side-effects.

Even the American Academy of Dermatology has advocated for Blue Light Therapy in fighting skin diseases. Here are the benefits of blue light therapy:

  • Used in various sleep-related problems
  • Destroys bacteria P from your skin to help with acne
  • This kind of therapy is inexpensive and can be taken in or outside the office of any dermatologists

There are some downsides to it as well:

  • It could cause dry skin
  • It can create redness in the skin
  • Also, cause swelling

To Wrap It Up

Light therapies such as these have been approved by scientists all over the world. Not just that, they are being advocated for by scientists and doctors alike. These light therapies are not hard to get and are inexpensive, making it the perfect solution for some people.

There are a lot of myths and conspiracies about how these kinds of therapies wouldn’t work. These theories are there to decelerate the prosperity of science. There are hundreds of scientific research based upon these therapies, and you can look them up yourselves before believing in any such theories.
