Little Light


Little Light is a flat packed light product that eases the symptoms of Seasonal Affective Disorder (SAD). It’s a self-assembled, inexpensice design product, that makes light therapy accessible to everyone.

The product is designed to be flat packed and light, in order to be inexpensive to produce, easy to deliver by post and ideal for online sale. Little Light could be described as something between a light and a seasonal greeting card.

The market

Over 12 million people across Northern Europe are affected by Seasonal Affective Disorder. It’s known as the “winter blues”, a syndrome characterized by recurrent depressions that occur annually at the same time each year. In Finland for example, the first symptoms can appear in September, lasting until April. SAD is often self-daignosed so the treatment should be low threshold and easy to access.

Currently, the majority of light therapy products are large, even technical-looking and can easily cost up to 200€, making it an investment not everyone can make. Their recipe of light color and brightness varies from product to product and some are completely dependent on the placebo effect.

While researching SAD, I had an insight on how in addition to long dark periods, countries with SAD sufferers have abnormally light summer periods. Most people that own large light therapy products in small flats, store them away for the summer.

The flat packed light is easy to store away for the summer, or with the right material choices, it could even be recycled in the spring, when it’s no longer needed.

Dark winters are also common to lessen social con­tact between people. Little Light is a nice way to remember firends and family when the dark winter months approach, a greeting card with a function!


How it works

Little Light works by affecting melatonin secretion in the body. Melatonin, the hormone that makes you feel sleepy, is controlled by the light entering through your eyes into your retina. Little Light uses a specific color of light (6500K), that has been proven to decrease melatonin production and thus making you feel more alert. Just 10min. exposure a day has been proven to ease SAD sympotms.
