Терапия красным светом (RLT) shows some potential and promise in depression treatment.
The following is a detailed analysis of Red Light Therapy in depression treatment:
I. Basic Principles of Red Light Therapy
Red Light Therapy is a method of treatment utilizing low levels of red light, whose wavelength is usually between 630nm and 700nm. This therapy works in a non-invasive way by irradiating light into the body to activate the mitochondria within the cells, which in turn promotes cellular energy (СПС) production and other biological effects.
II. Application of Red Light Therapy in the treatment of depression
1、Improvement of mitochondrial function: mitochondrial dysfunction is an important aspect in the pathogenesis of depression. Red light irradiation can activate mitochondria, increase their catalase activity, and promote sugar metabolism and ATP production, thus improving cell function, especially the function of nerve cells.
2、Anti-inflammatory effect: The pathogenesis of depression is closely related to the inflammatory response. Red light irradiation can up-regulate anti-inflammatory factors to avoid neuroinflammatory reactions, thus reducing depressive symptoms.
3、Modulation of neurotransmitters: Reduced functional activity of monoaminergic neurotransmitters (e.g., dopamine and 5-hydroxytryptamine) is considered to be one of the important pathogenic mechanisms of depression. Red light therapy has been reported to enhance dopaminergic transmission in brain regions, thereby improving depressive symptoms.
4、Regulation of biorhythms: Depressed patients often suffer from biorhythmic disorders, especially seasonal depression. Red light inhibits melatonin secretion and regulates circadian rhythms, thereby improving sleep and mood.
What is Depression? Symptoms and Treatment
According to the American Psychiatric Association, depression, also known as major depressive disorder or MDD, “is a common and serious medical condition that affects how you feel, the way you think and how you act”. While many associate the condition with sadness, it has a host of other symptoms that can significantly impair a person’s life and well-being. Some of these include:
*Lack of motivation or loss of interest in activities once enjoyed
*Sleep disturbances (insomnia or sleeping too much)
*Irritability or angry outbursts
*Lack of energy or extreme fatigue
*Lack of appetite or increased food intake
*Anxiety or restlessness
*Feelings of worthlessness
*Difficulty thinking or concentrating
*Thoughts of death or suicide
*Unexplained physical symptoms (aching muscles and joints or headache)
The number and severity of symptoms can vary from one individual to the next. Typical treatment for depression involves medication (there are hundreds of medications used to treat the condition, and it can take a lot of trial and error to find one that works for the individual), therapy (cognitive-behavioral or psychodynamic therapy, for instance), or a combination of both.
Perhaps you’re looking at the list above and thinking, “This sounds like me”. Or maybe you have a diagnosis and you’re looking for an effective way to supplement your current treatment. Whatever your situation, it’s crucial to embark on this journey with your doctor, as self-diagnosis and unsupervised treatment can have dire consequences.
III. Clinical Studies and Evidence
In recent years, more and more clinical studies have supported the application of Red Light Therapy in the treatment of depression. For example, a research team from the City University of Hong Kong found that red light irradiation can activate mitochondria and promote cell synthesis, which is conducive to the repair and regeneration of damaged tissues, and then stimulate neural tissues to achieve therapeutic purposes. In addition, a study conducted by a team from Wenzhou Medical University and Zhejiang Key Laboratory of Neurology Research also showed that red light irradiation can improve depression-like behavior in mice.
IV. Why use red light therapy?
When we don’t get adequate natural light, it affects every cell and process within our body. Humans were made to use sunlight for optimal health. Healthy light is essential to every cell’s function, and a lack of light can lead to chronic disease and illness.
Lack of sunlight has been known to cause anxiety and depression because not enough sunshine depletes brain serotonin and dopamine levels, and those low levels can lead to disabling mood conditions. Staying indoors for extended periods affects mental well-being. In addition to clinical depression and anxiety, low levels of Serotonin are also associated with depressive disorders like seasonal affective disorder (SAD), a type of mood disorder influenced by the changing daylight hours.
Red light therapy can specifically:
- Increase sluggish energy levels
- Support a balanced mood
- Improve mental clarity and confidence
- Improve general positivity, and calm, and reduce anxiety
- Reduce seasonal depression (SAD)
While red light therapy devices can have these benefits, they should never replace working with a mental health professional or other treatments for anxiety, depression, or the like.
В заключение, Терапия красным светом, as an emerging non-invasive treatment method, shows some potential and promise in the treatment of depression. With the deepening of research and the continuous development of technology, it is believed that it will bring benefits to more depressed patients in the future.
