7 best SAD lamps to brighten your mood, tried and tested
Our top picks are designed to help alleviate the symptoms of seasonal affective disorder

Searching for the best SAD lamps to boost your health and wellbeing? You're not alone. According to research, one in three people in the UK suffer with seasonal affective disorder (SAD).
“It’s a type of depression that comes and goes in a seasonal pattern,” explains Claire Nevinson, superintendent pharmacist at Boots UK. “Symptoms are usually more severe during the autumn and winter months and improve with the change of season in the spring or summer.”
While symptoms vary from person to person, they can include persistent low mood, irritability and lethargy, as well as feelings of anxiety and stress. “You may also lack energy, find it harder to concentrate and struggle to get up in the morning,” adds Nevinson.
The exact cause of SAD remains a mystery, but experts believe it’s linked to reduced sunlight exposure during autumn and winter. Fortunately, there are a range of lifestyle changes and therapies that can help ease the symptoms. One of the most popular is light therapy – a treatment backed by the NHS that involves sitting in front of a light box (SAD lamp) during the dark mornings. Evidence shows that just 20 minutes of light exposure can have a major impact on your mood.

What is a SAD lamp?
Unfortunately, your trusty old desk lamp won’t do the job when it comes to tackling seasonal blues. SAD lamps, on the other hand, are specially designed to blast out full spectrum light to mimic natural sunlight – exactly what we’re missing on darker days.
GP and longevity expert Dr Alka Patel explains that on a typical, clear-sky day, outdoor light provides 10,000+ lux (lux is the measurement of brightness), while indoor light only offers around 500 lux.
When it comes to choosing a SAD lamp, the general recommendation is 10,000 lux, but you can opt for a lower-intensity light box, as long as it’s above 3,000 lux. “These have also been shown to provide benefit, but they may require longer sessions,” says Dr Patel.

How do SAD lamps work?
According to Dr Patel, light therapy encourages your brain to produce serotonin, aka “the happy hormone”. It also optimises the production of melatonin (the hormone responsible for sleep) and helps regulate your internal body clock, promoting better sleep-wake cycles.
“The brain needs to register a difference between morning and night light in order to initiate the production of melatonin and encourage sleep,” says Dr Patel. “If you spend the whole day indoors, without enough bright light exposure, you’ll likely have issues come bedtime. A SAD lamp can help combat this.”
This is why a SAD lamp isn't just for winter – it can be a great option for getting that extra bit of sunlight exposure (and its mood-boosting, sleep-enhancing effects) all year round.
Dr Patel points out that by mimicking sunlight, which is a natural mood-booster, the best SAD lamps can also increase alertness, enhance your energy levels and improve your overall sense of wellbeing.
