There are a few important considerations to make before you decided which light box will help you the most.
Light therapy for SAD comes in different light intensities. Light boxes differ in light intensity, size, shape and features. These are the things you should consider to find the safest and most suitable light box for your needs:
Light Intensity – Look for a light box that provides the right intensity of light when you’re a comfortable distance away. For example, it may be effective to use a light box that produces 10,000 lux (a measurement of light intensity) at 24 inches from you for 30 minutes each morning.
Does it have Blue Light? Blue light can cause damage to your eyes so avoid a light box that uses blue light, especially if you have a history of eye issues.
Does it have no UV light? – There are certain light therapy boxes for SAD that use broad spectrum lights that don’t even emit UV rays. If you’re not sure, contact the manufacturer for safety information
Is the light box made for SAD and depression? Make sure you are not buying a light box designed for skin orders for example (red or blue light). You should look for a light box specifically for SAD or depression for it to be safe and effective for you.
Style and features – Make sure the size of light box fits your needs. Keep in mind; most light boxes need to be positioned within 2 feet of you.
Cost – The prices vary, but some health insurance companies cover some of the cost of light therapy for SAD, but you will of course have to get a prescription from your doctor.
