Best SAD therapy lamps in 2025 (UK)

There are a lot of things not to like about winter. It’s cold, it’s freezing, it’s windy and – yes – it’s very, very dark. And for us, that’s the worst: having to endure these short days and these dark mornings and evenings. The darkness takes its toll.

It’s exhausting trying to live your life without enough sunlight. This is especially true for office workers who spend every hour of the day stuck inside a building. It can be hard to get out of bed in the morning, and even harder to be productive and relax after the work day is over. But all is not gloomy.

SAD therapy lamps are a great way to relieve the winter blues. And there are a wide range of these devices available, helping to relieve SAD (seasonal affective disorder) symptoms if you don’t get enough natural light. All this means you don’t have to endure six months of darkness. But which SAD therapy lamp is best for you? Let us help you shed some light on the subject with helpful information and a selection of the best SAD therapy lights available today.

What is seasonal affective disorder?

As it sounds – and aptly abbreviated to SAD – seasonal affective disorder is a type of depression that follows a seasonal pattern. It usually affects people during the winter months, causing them to feel depressed, lethargic, anxious or irritable.

What causes seasonal affective disorder?

According to NHS guidelines, the cause of seasonal affective disorder is not fully understood, although it is usually linked to lack of sunlight, which can stop the brain from producing certain hormones or disrupt your body clock.

How does light therapy work?

Spending around 30 minutes in front of a light is thought to reduce the effects of SAD by simulating sunlight, which can encourage your brain to produce melatonin and serotonin to improve your sleep and mood. The NHS recommends light therapy as one of the standard treatments for seasonal affective disorder.

What does Lux mean?

You will often see this term when shopping for therapy lamps. Lux is the unit of measurement for light intensity. According to some research, a light intensity of 2,500 can improve your well-being. Most of the lights listed below have a lux of up to 10,000.

How big are light therapy lamps?

Although the desired effects are essentially all the same – a way to light yourself up – they come in a variety of shapes and sizes. Some are portable, allowing you to take them wherever you go, especially to the office, where a good amount of light can be difficult to find, while others are designed to stay in a fixed location.
