Light therapy is a commonly recommended treatment for people who suffer from seasonal affective disorder (SAD) or other mood disorders. The therapy involves exposing individuals to a bright light to mimic natural sunlight, with the aim of regulating the body’s internal clock and improving mood. However, there are concerns that light therapy may interfere with sleep and cause insomnia in some individuals. This article will explore whether there is any truth to these claims and what the research says about the potential effects of light therapy on sleep.

Understanding Light Therapy

Light therapy is a non-invasive treatment that uses specific wavelengths of light to improve various health conditions. It is often used to treat seasonal affective disorder (SAD), a type of depression that occurs during the winter months when natural sunlight is scarce. Light therapy is also used to improve mood, sleep, and skin health. It is a safe and effective treatment that has been used for decades.

How Does Light Therapy Work?

Light therapy works by exposing the body to bright light, which helps to regulate the body’s circadian rhythm. The circadian rhythm is the body’s internal clock that regulates sleep and wake cycles. Exposure to bright light helps to reset the circadian rhythm, which can improve sleep and mood.

Light therapy is a non-invasive treatment that uses specific wavelengths of light to improve various health conditions. It works by exposing the body to bright light, which helps regulate the body’s circadian rhythm. While generally considered safe, light therapy can cause insomnia as a side effect, particularly in people with a history of sleep disorders, sensitivity to light, or those who use it in the evening or for an extended period of time. To prevent insomnia, light therapy should be used in the morning or early afternoon, with lower intensity, for shorter durations and under the guidance of a healthcare professional. Despite its risks, light therapy has been shown to be an effective treatment for several health conditions such as SAD, depression, jet lag, skin health, and inflammation/pain, but it should be avoided by people with certain eye conditions, skin cancer, or bipolar disorder.

While light therapy is generally considered safe and effective, there have been some reports of insomnia as a side effect. Insomnia is a sleep disorder that makes it difficult to fall asleep or stay asleep. It can be caused by a variety of factors, including stress, anxiety, and certain medications.

One study found that exposure to bright light in the evening can disrupt the body’s melatonin production, which can lead to insomnia. Melatonin is a hormone that helps regulate sleep and wake cycles. Bright light exposure can suppress melatonin production, which can make it difficult to fall asleep.
