Whether a lamp can have a medical effect depends essentially on two factors: The light intensity and the colour temperature. For there to be a therapeutic effect, a light intensity of 10,000 lux is recommended. Trust the Germans to think of everything! So with this in mind, if you'd like to enjoy 'vitality', 'harmony' and 'relax' oil blends in your diffuser you are welcome to and these oils fit in well with our range of Aromatherapy diffusers Pros: Using cold fusion technology rather than water, your drops of the essential oil blend are converted into micro fine vapour without using heat or water and released into the atmosphere to stimulate your senses and boost your well-being. It's fully portable with 50 hours of battery life (lasting today, tomorrow and even a bit of the next day after that!) and has a USB charging port for your laptop. Plus, there is no need to clean in between. For comparison: In a well-lit office, the light intensity is just 500 lux. At the same time, electric light has an increased proportion of red light compared to daylight. Due to the low lux value and the increased red content, conventional electric lamps are therefore not sufficient to have a medical effect. According to Robert Tisserand, an Essential Oil Educator and Aromatherapy Expert from California, "Clinical studies have shown that aromatherapy by inhalation can have real benefits for people with, for example, anxiety, [problems with] mental focus, depressive symptoms, and menstrual pain."

It's worth purchasing at least two different oils to start with – ideally a relaxing one, made with ingredients such as lavender, and an energising one containing livelier notes such as citrus or spice. Some of the most powerful scents include lavender, which has been proven to activate our brains' GABA receptors, which in turn inhibit anxiety-producing brain signals. Beurer have crafted three specific aromas; perfect if you want to have a distinct ambience in each room of the home:

There for you around the world!

Aroma diffuser shade – with a porcelain outer cover, with a hole in the top to let the aromas escape and circulate.• Aroma diffuser base – made from strips of real bamboo, with mist/timer button, mood light button, LED timer display, it holds the water tank.

To start diffusing, remove the porcelain and inner covers, fill the water tank, and add 5-10 drops of your chosen water-based aroma oil to the water. Then carefully replace the covers, plug in the adaptor, and press the mist/timer button on the left to switch it on. Keep pressing to set the time, and hold to choose between intermittent or continuous mist. Robert Tisserand – one of the world's leading experts in aromatherapy and founder of Tisserand Aromatherapy. Further research has supported this, showing that essential oils can interact with the brain and nervous system to positively impact your health and mood. That said, Jo Kellet – essential oils expert at Tisserand – added that essential oils should not be applied directly to the skin, even with their numerous benefits. Indeed, Jo explained, “Essential oils need to be diluted before being applied to the skin in either a base oil, lotion, or cream, for example. They are concentrated essences that can, if used neat, cause a severe skin reaction, or over time build up a sensitivity to that essential oil.” Enter: the essential oil aroma diffuser.

The pineal gland releases the hormone, especially in the dark. The longer it is dark, the more melatonin is produced. Serotonin is considered a happiness hormone, wakes us up and has a positive effect on our mood. However, the two hormones are by no means just counterparts, as they are closely interdependent. Rather than using heat to ‘power’ diffusion, there’s an ultrasonic vapouriser in the middle of the water tank that safely uses high frequency sound vibrations to quietly break down water into ultra-fine particles of mist – so you don’t have to worry that it will sit in the corner of your room huffing and puffing away like a dragon! If you like the look of natural products in your home rather than anything too futuristic or minimal, then the best oil diffuser for you is this device from Innogear, which is made from bamboo. It offers four different diffusing settings to suit you and your home, including continuous mist, interval mist, a 2 hour mist timer or a 10 hour mist timer.
