Light Therapy: Potential Side Effects to Consider

Truvva - Sleep Better - Light Therapy

Light therapy, sometimes referred to as phototherapy, is a non-invasive medical procedure that uses particular light wavelengths to treat a range of illnesses. Its effectiveness & low side effects have contributed to its recent rise in popularity. In this post, we’ll look at the advantages of light therapy as well as any possible drawbacks & risks.

The way light therapy operates is by exposing the body to particular light wavelengths, usually from a light box or therapy device. Bright light that resembles sunlight is emitted by these devices. The body absorbs the light & goes through different physiological reactions, especially in the skin and eyes. The ability of light therapy to control the body’s circadian rhythm, or internal body clock, is one of its main advantages.

Bright light exposure first thing in the morning has the potential to reset the circadian rhythm, which can enhance sleep quality & provide you more energy all day. People with seasonal affective disorder (SAD) or other forms of depression will particularly benefit from this. Apart from its impact on the circadian rhythm, light therapy has demonstrated efficacy in treating an array of ailments, such as:- Seasonal affective disorder (SAD): SAD is a form of depression that manifests itself during the winter, when there is a reduced amount of natural sunlight. Increasing serotonin levels in the brain, which elevate mood and lessen depressive symptoms, is one way that light therapy can help with SAD symptoms. – Sleep disorders: Jet lag and insomnia are two conditions that can be treated with light therapy.

Light therapy works by adjusting the body’s internal clock, which helps to reset sleep cycles & enhance the general quality of sleep. – Skin conditions: Light therapy can help alleviate psoriasis and eczema, among other skin conditions. The particular light wavelengths used in phototherapy have the potential to lower inflammation & accelerate skin healing. – Mood disorders: It has been demonstrated that light therapy is helpful in treating bipolar disorder and non-seasonal depression, among other mood disorders. It can lessen irritability and anxiety symptoms while also assisting with mood stabilization. Despite the fact that light therapy is usually regarded as safe and well-tolerated, there are a few possible hazards and adverse effects to take into account. It’s critical to understand these hazards & speak with a medical professional prior to beginning light therapy.

Wearing the proper eye protection, such as goggles or sunglasses that filter out the particular light wavelengths used in the therapy, is crucial to protecting the eyes during light therapy.

Even when the light is not shining directly in the eyes, these protective glasses should be worn the entire time the light therapy session is in progress. Another crucial aspect of light therapy is to look away from the light source. This may result in short-term discomfort or possibly eye damage. Rather, set up the light box or light therapy device at an angle so that the body receives indirect light. It is crucial to cease light therapy sessions and speak with an eye care expert if you notice any changes in your vision or discomfort in your eyes.

When it comes to future light therapy sessions, they can evaluate any possible harm and offer advice on how to keep the eyes safe. A common side effect of light therapy is headaches and migraines, especially if the patient is not well-tolerated by the light’s intensity or its particular wavelengths. Recognizing this possible adverse effect and taking precautions to reduce the risk are crucial. Some people, especially those who are prone to light sensitivity or have a history of migraines, may experience headaches or migraines in response to the intense light used in light therapy.
