About the Brand

The manufacturer of the SunBox Sunlight Jr device is The Sunbox Company, also called Natural Illuminating Technologies Inc, located in Frederick. Maryland, United States. Founded in 1985, they have many years of experience developing quality light boxes for the treatment of seasonal affective disorder.

How Does it Work and What Are the Health Benefits?

SunBox Sunlight Jr emits white light which is similar to the sunlight outside, and mimics it in order to improve the symptoms of Seasonal Affective Disorder. The light increases levels of the brain neurotransmitter serotonin, which plays an important role in regulating mood.

A systematic review published in Molecular Psychiatry by Joanna Moncrieff, et al explained the research regarding the serotonin theory of depression [1].

The device also boosts the synthesis of the hormone melatonin, which promotes sleep. It can help regulate your sleep-wake cycle, improve quality of sleep, and even speed up your recovery from jet lag.

An article by G M Brown published in the Journal of Psychiatry and Neuroscience discussed the connection between light, melatonin, and the sleep-wake cycle [2].

Light therapy may also improve the symptoms of dementia, as one issue related to the disorder is a dysregulation of the sleep-wake cycle same as Vielight Neuro.

A research review in the Journal of Alzheimer’s Disease by Nicholas Hanford and Mariana Figueiro discussed the use of light therapy for Alzheimer’s and other types of dementia in the past, present, and future [3].

Expert Opinion on SunBox Sunlight Jr

Norman E. Rosenthal, world-renowned researcher and psychiatrist, explains:

This condition, also known as seasonal affective disorder (SAD), has been shown in many studies in the United States and elsewhere in the world to respond to treatment with bright environmental light (light therapy).

Light therapy is no longer considered experimental but is a mainstream type of psychiatric treatment [4].

A study published in the International Journal on Disability and Human Development by Gagan Virk, MD, et al concluded that symptoms of seasonal affective disorder improved even after one 20 minute session with light therapy [5].

How to Use It?

The manufacturer recommends that you use the light box in the morning, as use at night could disrupt your sleep. The sessions should be 20-30 minutes per day.

To use the box, sit in front of it so the light is in your face, and keep your eyes open for the duration of the session. However, there’s no need to look directly into the light.

Side Effects and Risks

In general white light is safe, as long as it does not contains UV rays. This device has a filter to block these rays and so it is low risk and has no associated side effects. All of the components of the light box have a U.L approved rating.

Great Light for Winter Blues

This is a great little light that is easy to move, yet big enough to provide the light you need. The company who sells this light couldn’t be more helpful! A real person actually answers the phone every time I’ve called. I’ve ordered two lights.

One came with a broken light, and they couldn’t have been more helpful. I called another time with a question about how to use it and again, they were very responsive. I highly recommend this company and this Jr. light. Linda Blair, Amazon customer

A Wonder Box

This box works wonders! It’s a great investment especially if you have problems with the lack of sunshine during the winter months.

It’s compact, so you can take it anywhere with you. I would recommend getting the case to protect it though. So glad that someone came up with this wonder box! Safi, Amazon customer

Nice Light Box

I was recommended this sun box for treatment of SAD. I really like the brightness of the light. It is truly like daylight when it is on. CCFRN, Amazon customer

    Completely change my mood.

    The SunBox SunLight Jr. light therapy devices I recently purchased, had a surprising impact on my mood and general well-being. It generates high-quality light, and its tiny size makes it convenient to use at home or at the office. I have seen a rise in energy levels and a considerable change in my sleep patterns after using it briefly each day. For those looking for a safe, all-natural method to treat seasonal affective disorder and to improve their mood.

    Highly recommended.

    In the winter months, Sunbox Sunlight Jr. has been a lifesaver for me. After using this device, I have noticed an improvement in my mood and energy levels, as I am suffering from seasonal affective disorder. The best thing is that it is easy to use, and its bright light helped me feel more focused and alert.
