Seasonal affective disorder (SAD) is a type of depression that's related to changes in seasons — SAD begins and ends at about the same times every year. If you're like most people with SAD, your symptoms start in the fall and continue into the winter months; sapping your energy and making you feel moody.

To battle the effects of this disorder especially in winter, Light Therapy is being practiced. Light Therapy is a way to treat SAD and certain other conditions by exposure to artificial light.

You undergo Light Therapy by working or sitting near a device called a light therapy box. It mimics the natural outdoor light that helps people with SAD have that summer vibe during the winter. Light therapy affects brain chemicals linked to mood and sleep, easing the irritation and mood swings that are likely to happen to people with SAD on winter or any other cold days, according to MayoClinic.

Here are the best light therapy boxes that are available right now through Amazon.

Carex Health Brands Day-Light Classic Plus Bright Light ($131)
It delivers 10,000 lux of illumination, which is just right for most of the people suffering SAD. A 30-minute session is enough to deliver the standard treatment for SAD. Day-Light Classic Plus delivers glare-free, white light via a 250-square-inch lamp.

Verilux HappyLight Deluxe ($136)
HappyLight delivers 10,000 lux from more than 14 inches away. It also has Flicker Elimination Technology for less flicker experience. This unit is preferable for people who values design and relaxation.

NatureBright SunTouch Plus Light and Ion Therapy Lamp ($55)
This product is one of the popular light therapy lamps in the market because of the competitive price compared to the other products. It also produces 10,000 lux and is 13-inches tall and 9-inches wide. It doesn’t have the elegant design of the other product though.

Verilux HappyLight Liberty Personal ($39)

This product is the most compact and the cheapest of all the other products in the list. It sacrifices power as it is only capable of producing 5,000 lux. You need to partake longer sessions to produce the same result.
