More Info

Light therapy is a type of therapy that has very ancient roots. In fact, the roots of light therapy can be dated as far back as ancient times in India about 3,000 years ago. In ancient India, sunlight was used for therapeutic purposes. This has been recorded in the most sacred of texts in Hinduism. These days, however, the benefits of light therapy have been very well established by multiple studies. The benefits of light therapy are derived from using visible or non-visible UV light, in order to treat a whole host of conditions. 

The more regular sources of light include things such as incandescent lamps, electric ares and also fluorescent lamps. One thing that must be mentioned about light therapy is that it will work best when it is done according to the specific needs of the person getting the therapy. Some of the factors involved include the circadian rhythm of the person and also the selection of a proper time is highly necessary if you want to make the best use of light therapy. 

Why use light therapy devices?

Two main properties that are involved within the biological grounds of this type of therapy, sometimes also known as phototherapy, includes the wavelength and also the intensity. The range of visible light has wavelengths that are roughly between 780 nm to 400 nm. Then there is the circadian rhythm which is very often called the natural clock of the human body. This circadian rhythm is responsible for two things. It helps us regulate our sleep patterns and it also assists with other types of physiological processes. 

Researchers have often made the use of bright white light in the past. This is generally a spectrum of wavelengths that is mixed and emulates daylight. This was done so as to study the effects of light on the circadian rhythm of a person. However, there have also been a lot of studies published recently which have been able to make some findings that point to the fact that blue light of the short-wavelength kind is very effective when it is compared against the other lights in the visible spectrum. This is due to the fact that it has much better properties for phase-shifting. 

Light therapy has the ability to target this natural body clock that we all have and it has the potential to reset the clock, according to the light and dark cycles. Therefore, we can see that one of the main benefits of making use of a light therapy device is that it can really help you to synchronize your sleep-wake cycle. You can synchronize it according to your desired tastes. It completely depends on you how you want to do it. When you sleep better, it has a very positive impact on your mood as well. Therefore, this is a major reason why using a light therapy device is so advisable for people who suffer from sleeping disorders. 

There is another form of light therapy that goes by the name of Photodynamic therapy. This is a pretty special kind of light therapy and it makes use of drugs known as photosensitizing agents alongside light. This really does have the ability to kill any cancer cells present in the body. Another huge benefit of this special kind of light therapy is that it can also do the traditional job of shrinking the sebaceous glands. These are a particular kind of drug that only really starts to function after being activated by particular form of light. Within the world of medical literature, this process is also known as photoradiation therapy, phototherapy, or photochemotherapy as well. 

Conditions that light therapy helps with

On top of the things mentioned above, light therapy really does have a whole lot of other benefits as well. We will be taking a better look at some of the more well known ones below. Read on to know more.

Beneficial for the skin

In case, you need proof that light therapy has the potential to do absolute wonders for your skin, just know that a lot of A-list Hollywood celebrities have been making use of light therapy in order to combat skin issues for a very long time. Light therapy has the ability to promote the production of collagen in the skin. This has a lot of benefits for the skin and it will help keep the skin looking young, firm and it will also fight visible signs of aging. These are things that more or less everyone wants. Hence, it is not surprising that light therapy has been getting so popular in the skin care industry. 

Seasonal Affective Disorder

Seasonal affective disorder is a type of depression. It generally occurs at only certain times of the year, usually around fall and winter, and it can be severely debilitating. The people who are most affected by SAD are the ones who live in places where there is not enough sunlight during the months of fall and winter. 

This lack of exposure to sunlight can really lead to a lot of problems. Depression is not a thing that can be taken lightly. In fact, a lot of studies have been able to rank it as being the leading cause of disability worldwide.

Light therapy can really help with SAD. A few sessions of bright light therapy has the potential to do wonders for a person suffering with Seasonal Affective Disorder. Light therapy, in essence, tries to emulate the natural light of the outdoors in an indoor setting. 

When you first embark on your light therapy journey, we highly recommend that you consult with your physician first. They can guide you the best and make sure that you get the most out of your light therapy devices.

Meta Description: The concept behind light therapy is an ancient one. Modern light therapy, applying those same thousand year old principles, has gained immense popularity within the healthcare industry. Read on to learn more about light therapy devices.
