Light therapy lamps, often referred to as SAD lamps or sun lamps, are designed to mimic natural sunlight and are commonly used to treat conditions like Seasonal Affective Disorder (SAD), depression, and sleep disorders. A frequent question among users is whether these lamps can be used all day. Below, we’ve compiled information from credible sources to address this question, using their original text to ensure authenticity and reliability.



Understanding Light Therapy and Its Purpose


Bright light therapy involves exposing your eyes to an artificial light source that emits intense light at 10,000 LUX to mimic sunlight. This exposure tricks your body into producing melatonin and serotonin. Light therapy is especially beneficial when sunlight exposure is limited, such as during fall and winter. Mental health professionals frequently recommend this treatment as it’s proven to relieve symptoms caused by seasonal affective disorder, circadian rhythm disorder, depression, and more.


A sun lamp, also called a SAD lamp or light therapy box, is a special light that mimics natural outdoor light. Light therapy, or bright light therapy, is an effective treatment for seasonal affective disorder (SAD). SAD is a type of depression that occurs during the fall and winter, when there are fewer hours of sunlight. Experts believe the light from a sun lamp positively affects serotonin and melatonin. These chemicals help control sleep and wake cycles. Serotonin also helps reduce anxiety and improve mood. Low levels of serotonin have been linked to depression.



Can You Use a Light Therapy Lamp All Day?


Using a therapy lamp for too long, especially too late in the day, can wreak havoc on your circadian rhythm. This can lead to you having trouble falling asleep at night. When first starting, be sure to limit your SAD light therapy time to 20-30 minutes per day. The only scenario where you should use a therapy lamp at night is if you work a night shift. Therapy lamps can be effective for shift work adjustment. However, you should avoid using it at night if you have a regular schedule. Doing so can cause your sleep-wake cycle to be thrown off, creating sleep troubles. It’s also been found that exceeding 40 minutes of light therapy has no additional benefits.


It is important to remember that overusing happy lamps (light therapy lamps) may lead to side effects such as eye strain, headaches, and sleep issues. Hence, in order to avoid such issues, it is important to follow the provided guidelines of using it for about 20 to 30 minutes a day. Thus, to prevent overuse, you will need to monitor your response to light therapy lamps and adjust as needed. Moreover, if you are experiencing sleep issues or any form of discomfort, it is advisable to reduce the timing and intensity of your light therapy sessions.


Some healthcare professionals generally recommend using light therapy lamps for about 20 to 30 minutes every day. This timeframe helps provide enough benefits from the light without overexposure. However, it is always important to remember that the duration of exposure changes from one person to another. It is also important to consider the intensity of the lamp, the condition that you are seeking to treat, and the response time it might take.



Best Practices for Using a Light Therapy Lamp


To be effective, you want to use your lamp early in the morning, when the sun is rising. We recommend doing so when the sun would be rising during summer periods. It’s best to turn your lamp on within an hour of waking for 20-30 minutes. This will trick your body into producing serotonin which will make you feel alert and awake. Morning light therapy has been proven to be more effective than midday or evening. A study found morning light therapy to have a 53% remission rate compared to 32% midday and 38% in the evening.


The dose of light that has proved to be the most beneficial is 5000 lux hours per day, which could take the form of, for example, 10 000 lux for one half-hour each morning. Most studies indicate that early morning treatment (before 8 am) is optimal. It is now well established that the therapeutic effect of light is mediated through the eye, although patients should not stare at the units directly. The typical treatment regimen involves sitting comfortably in a quiet setting about 16 inches (41 cm) from the unit, which is usually set on a table at an angle.


Place the lamp at a distance of around 2 feet away or as recommended by the manufacturer so that your eyes receive the benefits of light therapy. Stick to a schedule and use light therapy at the same time every day, coupled with cognitive behavioral therapy, mindfulness, and even yoga, to enhance its effectiveness.



Potential Risks and Side Effects


Light therapy is generally safe and does not require a prescription to use. If side effects occur, they’re usually mild and short lasting. Some people can experience mild headaches, nausea, dizziness, or eye strain when using the light box. These symptoms usually occur at the beginning of treatment, and get better in a few days. Otherwise, they can be relieved by reducing the daily exposure time, or by sitting slightly farther away from the lights.


Occasionally, people report feeling irritable, or euphoric, or being “too high” when using light therapy. People with bipolar disorder (manic-depressive illness) should consult with a therapist or medical provider before using light therapy.


If you have bipolar disorder, Dr. Cain recommends using a mood stabilizer with a sun lamp because the added light exposure can cause a manic episode.

When to Consult a Doctor


If you are thinking about trying Bright Light Therapy, talk to your doctor first. Some people can have a bad reaction to the bright light in the first few days, such as suicidal ideation or hypomania, a state marked by excess energy and lack of sleep.


If you have eye problems (e.g., retinal disease, macular degeneration, or diabetes), or worries about eye damage, please see your doctor.


Do not use the light box too near bedtime, as the light exposure can disturb sleep. If this still does not help, contact your doctor.
