Full Spectrum Light Therapy

You may have heard of full spectrum light therapy before and wondered if it's something that can help you. Another kind of light therapy for depression, known as light box therapy, is also available and may be effective for treating a variety of conditions. When it comes to mental health, full spectrum light therapy is generally used to treat people who are experiencing seasonal affective disorder (SAD), but it may help those with other forms of depression as well.

How does full spectrum SAD light therapy work?

The science behind light therapy suggests that consistency is an essential ingredient to its success. For shift workers or people with busy schedules, compact light therapy devices may be a great option. These devices can be used in a shorter amount of time and may have different types of light therapy, such as blue or red light therapy. However, it's important to consult with your doctor or therapist to determine the appropriate type and duration of full spectrum light therapy for your needs.

When did full spectrum SAD therapy become popular?

People have believed in the power of sunlight for healing for centuries. Natural light has been used as a medical treatment for as long as people can document. However, full spectrum light therapy boxes didn't start to become popular until the 1990s. Since then, the number of success stories from the use of light therapy has continued to keep it in the spotlight.

Also, while blue light from screens can suppress melatonin (which helps with sleep), research has shown that exposure to blue light during the day can improve alertness.

The symptoms of seasonal affective disorder

This means that the symptoms of SAD usually start around the same time every year and leave around the same time every year. It can work like a cycle, and it's something that you're able almost to predict.

Symptoms of depression may include feeling sad or down but can also include feeling angry and more irritable. You may experience changes in your sleeping pattern and in your desire to eat. Some people sleep more, but others sleep less. Similarly, some people eat more, but others eat less. Many people experiencing depression also start to withdraw from friends and family and the things that they enjoy in life. It can almost make them want to shut down.

Why can't we just go outside?

If full spectrum light therapy is really just giving people artificial sunlight, why can't they just go outside to take in actual sunlight? The best light is natural sunlight. However, in this day and age, there are many people who experience a shortage of the natural sunlight that they need. This could be people who work long hours and find themselves leaving for the office when it's dark in the morning and not leaving until it's dark at night. 

Full spectrum light therapy also comes into play for SAD in states that experience less sunlight during the winter months. Many people are affected by SAD between fall and early spring. This is because many states have more cloudy days in the winter, and when you combine that with shorter daylight hours, it can lead to depression for some people.

Unlike being outside where the amount of natural sunlight can vary, light therapy boxes can provide a consistent and controlled amount of light exposure for those who may not be able to get enough natural sunlight throughout the day.

How to get a SAD light therapy box

You can buy a SAD light therapy box online or in stores without having any type of a prescription. However, it’s still recommended that you talk to a doctor or therapist before getting one.

There are some adverse side effects that you can experience if you do not use a full spectrum light therapy box correctly. There are also some people who shouldn't use therapy boxes. Therefore, if you buy a light box without talking to a doctor first, you could see a decline in your health instead of the benefits that you’re looking for.

Light therapy boxes can range in price from $20 to thousands of dollars. This is another reason why you might want to talk to a professional before buying one. Buying the cheapest box may not be the best option for your mental health challenges, but you may not need to spend thousands on a box, either. 

Another factor that you might consider when purchasing a light therapy box is UV rays. There are many boxes available on the market that are UV free. The Verilux HappyLight, for example, mimics sunlight without UV rays, as does the Carex Day-Light Classic. The Carex Day-Light Classic has two light mode settings, allowing you to use it as a desk lamp when it’s not being used as a therapy light. Some therapy lamps, such as the Verilux HappyLight, come with a satisfaction guarantee.

If this all sounds a bit overwhelming, you may also find comparison guides helpful in making your selection. News outlets including The New York Times, The Huffington Post, and Good Housekeeping, among others, walk through the differences across makes and models offered by leading manufacturers.

What should I do if I think light therapy would work for me?

If you think that full spectrum light therapy is right for you, it may be helpful to consult with a therapist who specializes in or has experience with this type of treatment. They can provide guidance on the course of therapy that would be best for your specific needs.
