Light Therapy Lamps Review
Why Buy a Light Therapy Lamp
Seasonal Affective Disorder (SAD) affects many people. During the winter months, when the days are shortest, you experience less direct sunlight. This dark season commonly prompts periods of lethargy and sadness, but it's theorized that exposure to artificial light can help treat these symptoms by stimulating chemicals in the brain that influence mood. You can learn about SAD lights, including the Northern Light Sadelite Desk Lamp, the Amjo Sun BRIGHT and the Sperti Vitamin D Lamp, right here.
Research suggests that exposure to artificial light offers several benefits to the human body. SAD lights mimic natural light. This artificial light helps your body generate vitamin D, which normally occurs when you have proper exposure to natural sunlight, and it bolsters more than your mood. Vitamin D can affect bone strength and susceptibility to heart disease.
Light Therapy Lamps: What to Look For
While there are many light therapy lamps available, not all provide the same type or intensity of light. Some lamps provide ultraviolet rays, the same rays the sun does. Others limit UV rays, but generate narrow-band light with short wavelengths to help with blue-light therapy. Whichever style of sun lamp you need, there are a few important aspects to consider.
Many light-therapy programs require light sources that generate at least 10,000 lux, which is equivalent of full daylight. Each program differs, but most require this level of intensity for at least 20 minutes every day. Sun lamps with lower lux levels may not provide the light you need to generate higher levels of Vitamin D, but they may offer other benefits.
Full-spectrum light remains an important part of many light therapy programs. The light emitted from this type of lamp looks much like sunlight and offers many of the same benefits. Some programs, however, require lamps that do not produce a full spectrum of light. Blue-light therapy lamps help with melatonin production, which affects circadian rhythms in the brain.
The size of your light therapy lamp plays a big role in how the device can be used. While small lamps sometimes feature 10,000 lux light levels, they may not work at the same distance as larger units. The lux measurement works in conjunction with your distance from the lamp to determine the efficacy of the therapy session.
While UV rays help you generate Vitamin D, they can also damage your skin. This potential harm sometimes outweighs the benefit, so many SAD lamps limit UV rays entirely. Other lamps emit UV rays and require the same precautions you would take when exposing yourself to direct sunlight.
Light therapy lamps address seasonal depression. They can affect sleep cycles and encourage healthier energy levels throughout the day. With the right lux levels and light spectrum, a light therapy lamp can help with many aspects of your life.
