There’s a big difference between a product that smells great and a fragrance that is scientifically proven to work. At This Works, you’ll see the term ‘functional fragrance’ used a lot. This is because our fragrances have undergone multiple clinical and independent studies and have been tested using fMRI (Functional Magnetic Resonance Imaging) to prove they help you fall asleep faster, feel more relaxed, and enjoy better quality sleep. Aside from these studies, we run a panel of 750 This Works customers who test each of our products, and we won’t launch something unless 70% of chosen panelists agree ‘This Works’. We mean it when we say it’s not just our name, it’s our promise. Keep reading to discover more about the renowned Deep Sleep functional fragrance and what it can do for you and your sleep.

harnessing your nose-brain connection
Our award-winning, bestselling sleep aid, deep sleep pillow spray, is formulated with a natural, aromatherapeutic Superblend of Lavender, Camomile and Vetivert. Each of these essential oils is renowned for its calming properties, and when blended together they create the powerful fragrance that helped 97% of users in our clinical study sleep better. Aside from smelling luxuriously inviting, our Deep Sleep functional fragrance activated areas of the brain associated with emotions, pleasure and calmness when tested in an fMRI study on 30 people in 2017, which concluded that the fragrance has the potential to encourage a pre-disposition towards sleep.* So each time you spritz this on your pillow, linens and pyjamas, you’re using a scientifically proven formula to pave the way for a peaceful night’s sleep.
a natural remedy for anxious sleepers
There’s a reason why people who suffer from sleep anxiety favour deep sleep pillow spray. Studies, testing our pillow spray vs a placebo on 200 male and female panellists with mild sleep anxiety, found that using deep sleep pillow spray before bedtime helped them fall asleep faster, enjoy a deeper sleep, feel less anxious before sleep and less tired in the morning (and throughout the day). A fast-acting solution, this one-of-a-kind blend is clinically proven to provide relief for temporary sleeplessness and for those who need a little more help switching off from daily worries. 
tackling a tech-heavy mind
The use of tech before bed has become a growing concern over the last decade. This Works conducted studies in 2014 and 2016 on men and women who were former sleep-prescription users and heavy technology users (using devices up to one hour to and including the hour before sleep) to test the effects of deep sleep pillow spray vs a placebo. Results from our study in 2014 showed 97% of deep sleep pillow spray users said they slept better than normal, 98% were more refreshed come morning and 100% said they’d recommend it to a friend.* Results also showed that the functional fragrance reduced sleep anxiety, improving the quality of sleep and the length of time they were asleep. **
