In a number of articles, we were stressing out how important sleep is and how dangerous overexposure to blue light is…this time, however, we are going to present to you the so-called light therapy.
It will surprise you with its methods and the reasons “why”!
Eager to learn more? Let’s go!
Light therapy or also called phototherapy.
It includes exposure to daylight or to light at specific wavelengths of light using polychromatic polarized light, lasers, light-emitting diodes, fluorescent lamps, dichroic lamps or very bright, full-spectrum light.
Doctors expose patients to the light for a certain amount of time and sometimes, at a set time of the day.
We use light therapy in order to treat the seasonal affective disorder (SAD) and a few other conditions by exposure to artificial light.
Phototherapy affects brain chemicals which are responsible for the regulation of mood and sleep. In turn, this eases SAD symptoms.
Japanese scientists have run an experiment in order to determine how bright light affects the body.
They did not get a full picture of it but cleared out some of the unclarities.
Atsushi Ishida and his teamwork at Kobe University’s medical school in the field of brain science.
The scientists started by exposing mice to bright light.
They noticed the mice experienced a wave of glucocorticoid hormones.
The latter are linked to processes in the body such as metabolism, response to stress, inflammation, and immunity.
The team of Ishida did a couple of different tests on the mice.
However, they did not do the experiment on humans.
This could be actually quite easy – hormone levels after exposure to light should be checked.
Nevertheless, the findings can serve as an explanation of the effectiveness of light therapy in treating SAD or other types of depression.
After a short look at the experiment of the Japanese scientists, here are the conditions in which we use light therapy:
It is believed that light therapy is effective in cases of SAD because it resets the body’s biological clock.
Symptoms like depressive behavior, fatigue and sleepiness are eased and the results last for up to 1 month.
The light therapy is definitely a better option than antidepressants since it is mostly safe and easy.
Even though a review from 2015 concluded that serious methodological flaws occurred in studies previously conducted.
These studies originally proved the positive impact of light therapy on patients with non-seasonal depression.
Therefore it is still being used in such cases.
Here are included circadian rhythm sleeping disorders, chronic circadian rhythm sleeping disorders, and sleep disorders in Parkinson’s and Alzheimer’s diseases.
In addition to the previous ones, we also use phototherapy as a treatment for skin conditions.
This kind of light therapy is different though.
The lamp for it emits ultraviolet light (UV).
If you don’t filter the light, the treatment is not suitable for other disorders because it can harm the eyes and the skin.
If you do not have a skin condition, you should be very careful about what kind of lamp you choose.
Of course, in case you do it yourself. Make sure that the lamp emits as little UV light as possible.
This way it would be safest!
Talking about safety, we should say that light therapy is safe in general.
Although it is not impossible side effects to occur, they will most likely be mild and won’t last long.
Some of them might be:
-Agitation linked to bipolar disorder.
Side effects will probably occur at the beginning of light therapy.
They should go away on their own in a few days.
Yet, you can try to regulate them. How?
Move further from your lightbox, take regular breaks during prolonged sessions or change the time of the day you use it.
If you have any other concerns or would like to hear more advice on the topic, talk to your doctor.
Nevertheless, always have a health professional guide you while you are under light therapy!
