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.<\/p>\n

It will surprise you with its methods and the reasons “why”!<\/p>\n

Eager to learn more? Let\u2019s go!<\/p>\n

Introduction<\/h2>\n

Light therapy or also called phototherapy.<\/p>\n

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.<\/p>\n

Doctors expose patients to the light for a certain amount of time and sometimes, at a set time of the day.<\/p>\n

What do we use light therapy for?<\/h2>\n

\"\"<\/a><\/p>\n

We use light therapy in order to treat the seasonal affective disorder (SAD) and a few other conditions by exposure to artificial light.<\/p>\n

Phototherapy affects brain chemicals which are responsible for the regulation of mood and sleep. In turn, this eases SAD symptoms.<\/p>\n

The experiment from Japan<\/h2>\n

Japanese scientists have run an experiment in order to determine how bright light affects the body.<\/p>\n

They did not get a full picture of it but cleared out some of the unclarities.<\/p>\n

Atsushi Ishida and his teamwork at Kobe University\u2019s medical school in the field of brain science.<\/p>\n

The scientists started by exposing mice to bright light.<\/p>\n

They noticed the mice experienced a wave of glucocorticoid hormones.<\/p>\n

The latter are linked to processes in the body such as metabolism, response to stress, inflammation, and immunity.<\/p>\n

The team of Ishida did a couple of different tests on the mice.<\/p>\n

However, they did not do the experiment on humans.<\/p>\n

This could be actually quite easy – hormone levels after exposure to light should be checked.<\/p>\n

Nevertheless, the findings can serve as an explanation of the effectiveness of light therapy in treating SAD or other types of depression.<\/p>\n
