Long, dark nights and short days are part and parcel of winter life in Britain. Throw in long working hours and, for many of us, daylight is almost unheard of during the cold months. With around 6pc of the population suffering from Seasonal Affective Disorder (SAD), and many more experiencing milder symptoms, SAD alarm clocks can be useful in overcoming seasonal depression.
Known alternatively as sunrise alarm clocks, wake up lights, body clock lights and natural light alarm clocks, SAD alarm clocks provide a novel form of light therapy that can have a big impact.
Light therapy has long been used to treat SAD, and these days it is possible to access the treatment at home through a sunrise alarm clock. It’s a relatively simple concept: the clock slowly emits light for 30 minutes before your desired wake-up time (many can be changed to increase or decrease light emission time).
This is designed to combat the sudden, startling awakening of a regular alarm clock, which releases cortisol and causes an imbalance in hormones, potentially leading to bad mood and inertia.
There are many on the market, ranging from around £20 to £200. They all perform the function of waking you with light rather than startling sounds, but the more expensive have features like DAB radios and reading lights. Check they are medically certified to treat SAD before purchasing.
The Telegraph tested some of the best wake-up light alarm clocks on the market. Here are our favourites:
1. Lumie Bodyclock Luxe 750D
Definitely a market leader, the Lumie Bodyclock Luxe 750D is a cut above its competition. “Why’s it so good?” I hear you ask. Well, it’s a pleasing mix of simplicity and high-tech features, and is incredibly easy to use for even the most technophobic.
While some sad alarm clocks are fiddly and complex to set up, the Bodyclock Luxe comes almost ready to go – all you have to do is set the time. It was even pre-set to wake me at my usual time of 7am.
Other reasons for this being the best? It looked more like a radio than a weird alien light, despite the groovy antenna. It had DAB, while many either had only FM or none, and Bluetooth and USB connections. Sound quality was better than most. The time light was less powerful than some, a bonus for sleeping hours.
With 20 wake up sounds, you’ll find the right one for you – I even awoke happily without any sound, just light (almost) as nature intended it. It’s pricey, but if you can afford it, this is the best wake up light I tried.
2. Lumie Bodyclock Active 250
The Lumie Bodyclock Active 250 is a more basic version of the Luxe Lumie alarm clock. While it doesn’t have many of the snazzier features of the more advanced version, it’s a lot cheaper. Aesthetically, it’s very similar.
Setting up is a little more complex; it took me a while to figure out all the right settings that I wanted. After that, I liked it. The clock light was on the dimmer side, which helped me when getting to sleep, and the morning waking light was in no way startling. You can set a particular FM radio station to wake you up, if you so wish, or several calming noises.
It’s a bit more high-tech than the Hangsun sunrise alarm clock, but not quite as versatile as the Bodyclock Luxe.
3. Withings Aura Sistema smart sleep
With a futuristic design and a number of features that set it apart, this is a good, if pricey, option for those after a new wake up light.
As a smart lamp, it does more than just wake you with ‘natural’ light. It can analyse your sleep cycle and tell you the temperature, light and sound in your room to help you achieve the optimum sleeping conditions. The sleep monitor fits under your pillow easily. You can then access the data through your smartphone.
The red light for falling asleep and blue light for waking up is another useful addition, as is Spotify compatibility.
4. Medisana Sunrise wake up light alarm clock
There’s a lot to like about this Medisana natural wake up light. Firstly, it’s design, which sets it apart from some other SAD alarm clocks.
Then there’s its eco-friendly credentials, with a long-lasting LED light – you can choose between seven colours for the lighting. Red aids melatonin, a hormone which helps sleep. The choice of noises is fairly broad, and we particularly like the soothing fireplace sounds.
Music-wise, the MP3 connectivity is fine, though sound quality isn’t amazing. Overall, a good option for those seeking a new wake up light clock.
5. ALFALED Sunrise Alarm Clock
A fairly basic light alarm clock, but it works well enough. It has a battery-powered option, though with limited functionality.
It took me a while to set up, and was a little fiddly. But the sad alarm aspect worked well. Of all the calming nature sounds available – cows, sheep, water – I opt for the comforting farm animals, a wistful longing for a rural life perhaps.
Like other sunrise alarm clocks, the light starts to turn on 30 minutes before alarm time, but this lamp probably wouldn’t suffice as a bedside lamp.
Overall, it’s not bad, the does-what-it-says-on-the-tin option. You’ll miss out on the jazzier aspects of some others, but it’s perfectly good nonetheless.
6. Beurer WL 90 4-in-1 wake up light
Beurer’s four-in-one sunrise alarm clock has a host of attributes, almost to the point of attempting too much. As a SAD wake-up light, it does the trick, and can be used as an ambient mood lamp too – at 256 different lighting options, you will definitely find the right one for you.
You can stream music or play via Bluetooth, and there are 10 wake-up melodies. Aesthetically, it may divide opinion, and it’s on the expensive side. But the Beurer light alarm clock ticks all the important boxes.
7. Philips wake-up light HF3520/01
The first thing that strikes you about this Philips SAD alarm clock is its resemblance to an old Apple Mac. Just like the sun, Philips’ wake-up light begins red, and within half an hour – to your desired wake-up time – turns bright yellow. It’ll leave you feeling positively nourished during the bleak winter months.
There are only five wake-up sounds, so less choice than some of the best SAD alarms, but the piano sounds are pleasant, and Philips state they’ve put a lot of clinical research into it.
With so many options out there, it can be tough to find the right SAD alarm clock. Prices vary drastically, but even the cheaper options will wake you with a soothing light.
For affordability, we particularly enjoyed the Hangsun, which doubles up as a very good reading light and has a big, accessible button on top for changing light strength.
The best wake up alarm, however, was the Bodyclock Luxe 750D from light therapy specialists Lumie. Not only does it look smart, it’s incredibly easy to use – even arriving with a 7am alarm time – and has extra features like a DAB radio.
