How SAD LED Light Bulbs Impact Health & Wellness?

In 1984, the Rosenthal publication conducted an experiment on 29 patients with symptoms of Seasonal Affective disorder (SAD) & identified benefits of light therapy on 11 of them. Seasonal Affective disorder (SAD) is a medical condition that involves depressive episodes that reoccur every year in certain seasons. An estimated 10 to 20% of recurrent depression cases follow a seasonal pattern. Light therapy by using SAD LED lights is the most widely used treatment for SAD. These lights effectively recreate sunshine, resulting in positive responses from patients.

Additionally, researches have shown that a particular bandwidth of white and blue light produced by SAD LED lights is highly effective in treating SAD. Also known as photo-therapy, light therapy benefits SAD affected individuals by regulating brain chemicals linked to mood and sleep.

Health Benefits of SAD LED lights

Besides treating Seasonal Affective Disorder (SAD) effectively, SAD LED lights have also been used to treat other medical conditions such as clinical depression, sleep disorder, dementia etc. The various health benefits of using SAD LED lights are as follows:

Balances body’s circadian rhythm

Seasonal Affective Disorder (SAD) light bulbs are primarily known for regulating circadian rhythms. Hectic life styles, depression and hormonal imbalances results in disturbed sleep cycles. SAD light bulbs recreate natural lighting that ensures adequate hormone production during night & help you sleep better.

Knowing the aforementioned benefits, globally renowned LED manufacturers and suppliers are developing specially designed SAD LED lights and circadian LED lighting bulbs for offices, households, and public spaces across the world.

Increases Vitamin D levels

Sunlight is the most popular source of vitamin D. According to various studies: a low level of vitamin D can lead to depression. Seasonal Affective Disorder (SAD) light bulbs produce small quantities of UV rays and infrared rays to mimic sunlight’s spectrum and deliver same benefits as natural light. Many people with SAD have deficient level of vitamin D. Multiple researches suggest that exposure to natural or artificial light that contains 100,000 IU can resolve the medical condition.

Aids clinical depression

It has been proven that depression is closely related with circadian cycle disorders. Patients with depression feel worse during winter due to a lack of natural lighting. When exposed to SAD focused lights, reports recorded better hormone production, primarily melatonin, during circadian clock cycle. This means lighting can be a big difference maker in treating depression.

Relives Sleep Disorders 

According to American Academy of Sleep Medicine (AASM), 25% of all sleep related disorders are directly linked with sleep/wake cycle. These sleep disorders include late night and early morning insomnia, irregular sleep patterns and sleep disturbances. Sunlight mimicking artificial bright light from Seasonal Affective Disorder (SAD) light bulbs effectively slows down the body clock to a normal rhythm, thus delaying the onset of melatonin and sleep.

Enhances productivity

Natural light resembling artificial lighting has been proven to improve office productivity, academic performance and reduced fatigue. Research conducted by American Society of Interior Design has shown that workers who were exposed to artificial light based on same phenomenon as SAD LED light performed 20% better than employees working in other environments. This was enough to encourage decision makers to embrace health focused lighting at their offices and workspaces.
