Light therapy lamps help ease the symptoms of seasonal affective disorder (SAD), which typically occurs when there are fewer hours of daylight including low mood, fatigue, and lack of focus. By recreating the effects of natural sunlight, the SAD therapy lamps boost levels of serotonin (the ‘happy chemical’) in your brain, to help you feel more energized, happy, and productive. SAD light therapy lamps are also effective at taking the edge off jet lag and help those who work night shifts light.
Carex Day-Light classic therapy lamp (opens in new tab)
For severe daylight deprivation
This LED therapy lamp emits 10,000 lux of glare-free white light with large, 16-by-13-inch coverage to deliver maximum results. The height and angle are adjustable on a flexible stand.
- Ideal for dimly lit home offices
- Fully adjustable stand
- Doubles as a task light
- Large size won’t suit all
This light therapy lamp projects light downwards, which is recommended by experts. There are also two settings so you can use the Carex as a standard desk lamp, too. Used for just 20 to 30 minutes in the morning, over time this SAD lamp will boost your energy and improve your mood. While the large coverage 16 x 13in screen delivers maximum results, there’s no denying this light therapy lamp might be a little on the big side for some.

Masquerades as furniture

Do light therapy lamps work?

Light therapy lamps, or sun lamps, mimic outdoor light, which researchers believe triggers a chemical change in the brain that helps with the symptoms of low light levels, such as fatigue, low mood, and lack of focus.
Many reliable sources, such as the National Sleep Foundation are supporters of light therapy lamps, but while these SAD lamps are effective for most people, they won’t work for everybody or they might only work to a lesser degree. However, when tested against a placebo, studies showed the sunlamps genuinely do make a difference, whether it’s a little or a lot.
Ultimately though, proof can be found by testing out a lamp for yourself. There are plenty of cheaper options that you can start with to provide you with your 10,000 lux every morning. And, should you find the extra light beneficial, then you can upgrade to a lamp with more features or buy an extra one to take to the office – handy for those long winter workdays.
Can a sun lamp ease Seasonal Affective Disorder?
If you have SAD or any other type of depression, the first port of call should be with your doctor, but light therapy lamps can certainly help with symptoms. As ever, a well-rounded approach is needed, and if your moods and concentration are suffering because of SAD, other factors such as exercise, diet, and sleep need to be taken into consideration too.
While sources such as Harvard Medical School do not cite the lamps as being a cure-all for SAD, they do suggest the lamps are effective, but they may not be for everybody, especially if you have more severe underlying mental health problems.
Other trials have reported on the effectiveness of these lamps after putting them to the test on small groups of people. The American Psychiatric Association also claims that light therapy can certainly help, and has seen positive results in SAD patients within as little as one or two weeks.
