Feeling Blue? Don’t be SAD!

It’s not news that much of the country has been suffering through one of the coldest and snowiest winters on record. But if you’re feeling particularly down, it may be a sign of Seasonal Affective Disorder, or SAD.

The causes of SAD aren’t completely understood, but one theory is that a decrease in natural sunlight may cause the brain to create less serotonin, which helps regulate mood. People affected by SAD can be depressed, less energetic, fatigued, and prone to weight gain.

Although your doctor is the best authority on SAD, you might consider warming up your indoor spaces with the right light bulbs. Light therapy has been proven to assist in relieving the symptoms of SAD.

One characteristic of any light bulb is its warmth, which is measured on the Kelvin scale. The lower the number, the “warmer” the color, and the more it will have a yellow/red cast to it. Higher color temperatures have a bluer cast.

The traditional incandescent bulbs we’re all familiar with offer a low, warm light of around 2700K, depending on wattage. This compared to the sun at noon, which measures 5500K.  



If you’re looking to imitate natural daylight in your home or office, you need a cooler light bulb, such as those offered by certain LEDs and full spectrum bulbs. A full spectrum bulb spans all colors, as in a rainbow, and contains infrared and ultraviolet wavelengths. It closely imitates natural sunlight and can help in treating SAD.

As an added bonus, LEDs enable you to select from a much broader range of color temperatures as compared to other bulb types. We recommend these LED bulbs if you’re looking for a mid-winter boost:
