What Is Light Therapy and Is It Right For You?

Light therapy, also called phototherapy or bright light therapy, is a treatment involving exposure to artificial light at controlled wavelengths and time points to treat a variety of medical and non-medical conditions. Most studied for Seasonal Affective Disorder (SAD), circadian rhythm sleep disorders, and other forms of depression, light therapy emulates the beneficial properties of natural sunlight.Light therapy is beneficial for various health conditions, including: Seasonal affective disorder (SAD) Depression and anxiety disorders Sleep disorders, such as insomnia Travel related jetlag Skin conditions, such as psoriasis and eczema Chronic pain, such as fibromyalgia What is light therapy and how does it work? The human body has a natural response to light, which helps regulate our sleep-wake cycle, mood, and overall well-being. Light therapy works by mimicking natural sunlight and stimulating the production of specific hormones and neurotransmitters in the brain. This imitation of sunlight is key in helping to set or reset our body's natural clock, which can improve mood-related issues.One example is the hormone melatonin, which helps regulate our circadian rhythms. Exposure to light, especially blue light, can - in the evening hours and at night - suppress the production of melatonin, in addition to making us more alert and energized. This is why it is often used to treat SAD or other forms of depression.Moreover, light therapy can also affect the production of serotonin, a neurotransmitter responsible for regulating mood (Serotonin is a precursor of Melatonin). Serotonin levels tend to be lower during the winter months when there is less sunlight, leading to symptoms of depression and anxiety. By increasing serotonin levels through light therapy, individuals may experience improved mood and reduced symptoms of depression. Types of Light Therapy There are different types of light therapy, each utilizing a specific wavelength or color of light. The most common types include UV, red, blue, and infrared light therapy. The different types of light therapies work by targeting specific cells or tissues in the body. For example, UV light therapy targets skin cells, while red and infrared light therapies target blood vessels and muscle tissue. UV Light Therapy UV (ultraviolet) light therapy uses ultraviolet rays to treat skin conditions such as psoriasis, vitiligo, and eczema. This type of light therapy works by slowing down the growth of skin cells and reducing inflammation. It is typically administered in a controlled medical setting using special lamps or light boxes. Red Light Therapy Red light therapy, also known as low-level laser therapy (LLLT), uses red or near-infrared light to promote healing and reduce pain and inflammation. It has been found effective in treating skin conditions, such as acne and rosacea, as well as reducing joint pain caused by conditions like arthritis. Red light therapy can be administered through specialized devices or in a clinical setting. Blue Light Therapy Blue light therapy is primarily used to treat circadian related issues (e.g. sleep, energy levels, digestion, etc.) as well as skin conditions such as acne. Circadian effects are elicited by directing light into the eyes, activating melanopsin in the photosensitive retinal ganglion cells responsible for non-image-forming visual functions. Moreover, these functions facilitate hormone secretion, synchronize circadian rhythms, and impact cognitive and affective processes. The skin condition treatment works by killing the bacteria that cause acne and reducing inflammation. This type of light therapy can be administered through special lamps or handheld devices. Infrared Light Therapy Infrared light therapy utilizes infrared rays to penetrate deep into the skin, providing relief for muscle and joint pain. It is also used to promote healing in wounds and injuries. This type is often administered through specialized devices or in a clinical setting. How does light therapy work? Light therapy operates on the principle of photobiomodulation, a process where light exposure stimulates cellular and tissue activity which sets off a series of biochemical reactions. As cells are exposed to light, they absorb photons and convert their energy into a form they can use to carry out vital functions, such as tissue repair and the production of collagen. This therapy has been shown to help support the production of adenosine triphosphate (ATP), the energy currency of the cell, thereby enhancing cellular metabolism and accelerating the healing and regeneration of tissues. In terms of circadian rhythm regulation, light therapy plays a crucial role by influencing the body’s internal biological clocks that dictate our sleep-wake patterns and energy levels. The timing of light exposure is key: morning light therapy can suppress the production of melatonin, the hormone that signals the duration of darkness to our body, and which can help promote alertness during the day. In contrast, dimming lights in the evening can help maintain melatonin levels, supporting the process of synchronization of our bodily rhythms. Additionally, light therapy has been found to increase serotonin production, a neurotransmitter associated with mood and well-being (Serotonin is a biosynthetic precursor of melatonin). This is particularly beneficial during winter months when daylight is limited, helping to alleviate symptoms associated with Seasonal Affective Disorder (SAD). Who is light therapy good for? Individuals with Seasonal Affective Disorder (SAD): Light therapy is a well-established treatment for SAD, a type of depression that occurs at a specific time of year, usually in the winter when daylight hours are shorter. Time of day of light exposure is of utmost importance to help treat SAD, because light at the wrong time of day can worsen SAD. People with Certain Sleep Disorders: Those with circadian rhythm sleep disorders, such as delayed sleep phase disorder, can benefit from light therapy. It helps to adjust their internal body clock to desired (often socially driven) times of wake and sleep. The time of day of light exposure is of utmost importance to help treat circadian rhythm and sleep disorders because light at the wrong time of day can worsen a disorder.  Patients with Non-seasonal Depression: Emerging studies suggest that the treatment may also be effective for non-seasonal depression, potentially helping to improve mood and well-being in individuals with major depressive disorder. Time of day of light exposure is of utmost importance to help treat depression, because light at the wrong time of day can worsen a depression. Individuals with Certain Skin Conditions: Conditions like psoriasis, eczema, and vitiligo have been treated with UV light therapy, which can help to slow down cell growth and reduce inflammation. People with Jet Lag or Shift Work Disorder: This treatment can help adjust the body’s internal clock for those who travel frequently across time zones or work irregular hours, improving sleep and alertness.  It’s important to note that while the method can be beneficial for these conditions, it should be used under the guidance of a healthcare professional to ensure it is appropriate for the individual’s specific health needs and to manage any potential side effects. To date, there is no off-the-shelf solution and any intervention using light in the context of shift- and night work is advised to be accompanied and supervised by a professional chronobiologist and expert on the non-visual effects of light in humans. Time of day of light exposure is of utmost importance to help treat related disorders, because light at the wrong time of day can worsen a disorder. Risks and side effects While light therapy is generally considered safe, it is not without potential risks and side effects. Awareness and proper management of these can help ensure a safe and effective treatment experience. Potential skin reactions Some individuals may experience skin reactions to light therapy specifically to UV and IR light therapy. Those with sensitive skin or conditions like lupus that can be exacerbated by light are especially prone to reaction. Reactions can include redness, irritation, or rash. UV-light therapy, used for conditions like psoriasis, carries a risk of skin burning similar to sunburn if not correctly monitored. Eye strain or damage: The eyes are particularly sensitive to light. Exposure to intense or prolonged light, especially very strong and unregulated UV blue light, can lead to eye strain. In some cases, without proper eye protection, there is a risk of damage to the retina. It is crucial to use light therapy devices that filter out UV light and to follow guidelines on duration and intensity of exposure. Precautions to take To mitigate risks, several precautions are recommended: Use light therapy devices that comply with safety standards and are recommended by health professionals. Start with shorter sessions and gradually increase duration under professional guidance. If using light therapy for skin conditions, apply sunscreen or other protective barriers as advised by a healthcare provider. Individuals with a history of skin cancer or retinal diseases should consult with a healthcare provider before beginning light therapy. Do not look directly into the light sources. Wear eye protection if recommended, especially for those with pre-existing eye conditions or when using light boxes that emit UV rays.   Devices and equipment for light therapy Light boxes UV (ultraviolet) light therapy uses ultraviolet rays to treat skin conditions such as psoriasis, vitiligo, and eczema. This type of light therapy works by slowing down the growth of skin cells and reducing inflammation. It is typically administered in a controlled medical setting using special lamps or light boxes. Dawn simulators Another type of popular light therapy device is a dawn simulator. This device works by gradually increasing the amount of light in a room, mimicking the sunrise. It is commonly used to help regulate ease of waking up . Light therapy wearables Wearable light therapy devices, such as eye masks or glasses, are also becoming more popular, especially as they provide freedom of movement and typically shorter sessions with equivalent effectiveness as light boxes. These devices use LED lights to target specific areas of the body, and can be used for adjustment of internal body clocks, energy levels, minimizing jet lag and improving mental performance. It is advised to precheck whether the device of choice has been subjected to scientific studies to validate its effectiveness.

Blue Light Therapy Glasses: The Hack to Better Sleep

Are you tossing and turning night after night, desperately trying to get a good night’s sleep? You’re not alone. Millions struggle with sleep issues, ranging from difficulty falling asleep to waking up feeling groggy and unrested. Traditional remedies like prescription medications often fall short. You might lie awake, staring at the ceiling, wondering if you’ll ever experience the rejuvenating sleep you crave. The consequences of poor sleep go beyond mere tiredness—they can affect mood, productivity, and overall health. But there is a science-backed solution that could help improve your sleep quality significantly: Blue light therapy glasses. In this comprehensive guide, we’ll explore how blue light therapy glasses work, their potential benefits, and whether they might be the sleep hack you’ve been searching for. Without further ado, let’s jump straight into the article. Did you know? The human eye has special receptors that are most sensitive to blue light wavelengths around 480 nanometers, called intrinsically photosensitive retinal ganglion cells or ipRGCs What Are Blue Light Therapy Glasses? Unlike traditional glasses that correct vision or block light, these specialized glasses emit specific wavelengths of blue light directly into your eyes. They are wearable devices that deliver controlled amounts of blue light. They typically consist of a frame with built-in LED lights that emit blue wavelengths between 460 and 480 nanometers. The primary goal of these glasses is to regulate our sleep and circadian rhythms. It’s essential to distinguish blue light therapy glasses from blue light-blocking glasses. While therapy glasses emit blue light and are typically used in the morning or during the day to increase alertness and regulate sleep cycles, blocking glasses filter out blue light and are worn in the evening to reduce light exposure for better sleep. There are different types of blue light therapy glasses, such as: Visor-style: These sit above the eyes like a visor, directing light downward. Glasses-style: Resembling regular eyeglasses, you can wear these over prescription lenses. An example of this is AYO’s blue light therapy glasses. Integrated-LED: Some models incorporate small LED lights directly into the frame of regular-looking glasses. When choosing blue light therapy glasses, you should consider light intensity (measured either in lux or melanopic EDI), battery life and charging method, comfort and fit, and additional features like programmable timers or app integration. Also, remember that while blue light therapy glasses are generally considered safe, they’re not suitable for everyone. People with certain eye conditions or taking photosensitizing medications should consult a healthcare professional before use. The Science Behind Blue Light Therapy Glasses Our bodies have evolved over thousands of years to respond to the natural cycle of light and darkness, developing an internal biological clock that regulates various physiological processes. Circadian rhythms are the 24-hour cycle part of the body’s internal clock. These rhythms influence numerous functions, including sleep-wake cycles, hormone release, eating habits, and digestion. The circadian system is primarily controlled by a region in the brain called the suprachiasmatic nucleus (SCN), often called the body’s master clock. Light plays a crucial role in regulating these circadian rhythms. Light entering our eyes stimulates special photoreceptors called intrinsically photosensitive retinal ganglion cells (ipRGCs). These cells are particularly sensitive to blue light wavelengths, which are abundant in natural sunlight. When blue light stimulates, ipRGCs send signals to the SCN, orchestrating various physiological responses. One of the most significant effects of blue light exposure is its impact on melatonin production.Melatonin is the ” hormone of darkness” because its levels rise in the evening and signal the night’s length to our brains. This is where blue light therapy glasses come into play. These glasses impact on our circadian rhythms by delivering a controlled dose of blue light directly to the eyes. When used in the morning, they can help suppress melatonin production, making it easier to wake up and feel alert. When used strategically during the day, they may help shift the body’s internal clock, benefiting people dealing with conditions like seasonal affective disorder (SAD) or jet lag. Potential Benefits of Blue Light Therapy Glasses Blue light therapy glasses offer a range of potential benefits, particularly for those struggling with sleep issues, mood disorders, or disrupted circadian rhythms.

What Type of Light Therapy Glasses Should I Choose?

Type of Light Used When selecting light therapy glasses, consider the type of light used. Most use LEDs, which are more energy-efficient and longer-lasting than fluorescent or halogen bulbs. Intensity and Spectrum of Light Any light can potentially affect our circadian rhythm. Different colors of light can affect our circadian rhythm differently. Blue light regulates sleep and mood strongly, while red light aids relaxation and reduces inflammation. For general light therapy, opt for full-spectrum white light, specialized blue light, or a combination of blue and red. Design and Comfort Since you will be using the glasses for extended periods, choose a design that suits your needs. Some have adjustable frames, while others come with headbands. Consider Your Goals Before making a decision, think about your goals for using light therapy glasses. Are you looking to improve your sleep, reduce symptoms of seasonal affective disorder (SAD), or increase your energy levels? Different glasses may be better suited for each goal, so do some research and choose accordingly. Bonus Tips for Using Light Therapy Glasses Consult your doctor before adding light therapy to your treatment, especially if you have underlying health issues. Follow the instructions provided by the manufacturer for proper usage and duration of wear. Use light therapy glasses consistently at the same time each day for optimal results or follow a personalized schedule. Pair light therapy with other healthy habits, such as regular exercise and a balanced diet, for overall well-being.

Why Use Light Therapy Glasses?

Light therapy glasses provide a simple alternative for those who do not have time to sit in front of a light therapy lamp or have limited access to natural sunlight. You can get light therapy treatment while performing daily tasks like using a computer or reading a book with these glasses. They are also portable, allowing you to take them with you wherever you go. There are a couple of factors that you should consider when choosing your first light therapy glasses:  Light Intensity: The effectiveness of light therapy depends on the intensity of the light source. To achieve optimal results, it is recommended to choose glasses with a light intensity lower than 10,000 lux due to the proximity of the eye. Wavelength: The ideal wavelength for light therapy is between 460 to 490 nanometers. This range is the most effective in regulating circadian rhythm and treating SAD. Adjustable Settings: Light therapy needs may differ from person to person, so it is important to find glasses with adjustable settings. Your light therapy sessions can be tailored to your desired intensity and length. Comfort and Style: Since you will be wearing these glasses for extended periods, it is important to find a comfortable pair. Why Choose AYO?

How Often Should I Wear Light Therapy Glasses?

Light therapy glasses are typically recommended to be used for 20-30 minutes per day, preferably in the morning. The reason behind this is that early-day exposure to strong light may help in regulating your body’s circadian rhythm, also known as the internal clock. This is crucial in controlling our sleep-wake cycle and general energy levels. The recommended duration of light therapy glasses usage may vary depending on your specific needs and circumstances. If you have been diagnosed with a certain sleep disorder or mood disorder, it’s best to consult with your doctor or healthcare provider. They can offer personalized advice on how often and when to use light therapy glasses. Light therapy glasses can be used for different durations based on individual preferences. It’s important to listen to your body and adjust accordingly. The frequency and duration of usage may vary, with some benefiting from multiple daily uses and others needing occasional use. Results may also be different from case to case, with noticeable effects in a few days for some and longer for others. Start with shorter sessions and increase duration if the effect is lacking. These glasses have multiple benefits, treating specific disorders and promoting overall well-being. Adding short daily sessions can improve mood, energy levels, and sleep quality. Use responsibly and try to get daylight or sunlight whenever you can to support better health
