As an anxious sleeper you may have difficulty with trying to calm your mind before bed, making it harder for you to drift off to sleep naturally. This is why incorporating our deep sleep pillow spray into your nighttime routine is the perfect solution. Scientifically formulated and proven to work for those who can't switch off. Take a deeper dive into the scientific benefits below.

Fall asleep faster - clinically proven
Our deep sleep pillow spray has been rigorously tested through 4 independent user studies with 600 participants and it's functional fragrance of Lavender, Camomile and Vetivert has been tested under clinical conditions in brain-scan studies (fMRI). The fMRI study concluded that This Works‘ Deep Sleep fragrance was seen to activate specific areas of the brain associated with emotions, pleasure and calmness with the potential to bring the mind into a pre-disposition towards sleep.1
Tested against a placebo over 28 days deep sleep pillow spray was proven to improve sleep quality and help relieve anxiety that may occur around getting to sleep. Participants in our studies also included 100 ex-sleep prescription and 100 heavy tech users- so we can be sure it really works. 


In our user studies we found that:
89% fell asleep faster*
97% slept better than normal*
98% felt more refreshed in the morning*
97% had less disturbed sleep*
*In a study of 100 subjects and 100 ex-prescription users compared to no product. Individual results may vary.
What is fMRI?
Functional magnetic resonance imaging (fMRI) measures the small changes in blood flow that occur with brain activity. These measurements allow us to examine the brain's anatomy and neurological wiring. By measuring the basal level of neural activity, and then, which areas are activated (shown by an increase in blood flow) by certain stimuli, such as aromas, we can link these stimuli to a certain neurological response or brain function such as memory, emotion regulation, and critical thinking to name just a few.1,2


Let there be light
Light is essential for humans; it adjusts the circadian rhythm and impact on many physiological and behavioural activities such as sleep, mood, neuro-endocrine function and cognition. Increased daytime light improves alertness, mood, performance and sleep and decreased light exposure in the evening and at night can promote sleep. It is essential to keep some regularity in the intensity, timing and length of light exposure in order to not alter the biological rhythms with negative impact on sleep, health, cognition and judgments.1,2 
It is thought to be important to ensure you are exposed to different wavelengths and intensities of light throughout the day to help maintain your circadian rhythm. One of the key moments is within the first 2 hours of waking, aim to get natural light into your eyes, without sunglasses, and don't look directly into the sun. The amount of time depends on cloud cover, it should be between 10-20 minutes. This triggers the timed release of a healthy level of cortisol into your system which acts as a signal to your body to wake-up boosting focus and alertness throughout the day. 3,4,5     
Modern humans are more often exposed to artificial light – resulting in less light during the day, while electric lightning during the night reduces or even removes darkness. The direction of light is also important as overhead lighting can activate receptor pigments (melanopsin etc.) located in the bottom of the eye de-synchronising the circadian rhythm. Late evening light exposure inhibits melatonin release, reduces sleepiness and delays the circadian clock. Even low levels of light in the sleeping environment have been associated to impaired sleep and metabolic dysfunctions. 3,4
Light is captured in the eye by photopigments. One of these pigments, melanopsin, is sensitive to a portion of the light spectrum, peaking in the blue colour. When melanopsin is activated it conveys information to the master biological clock in the brain (the suprachiasmatic nucleus), synchronizing circadian rhythms and regulating melatonin release. Melanopsin receptors have their own circadian rhythm they are particularly sensitive during evening and nighttime hours – explaining why exposure to even small amounts of blue light at night can have an important effect in destabilizing the circadian system. Increases in LED lightning in streets and buildings (sometimes more than 50% in some European cities) with increased blue light radiation increases suppression of melatonin regulating sleep.1,2,3,4,6 
Red light therapy is a term that uses both red light, with a wavelength of 600-700nm, and near infrared (NIR) that has a wavelength of 700 to 1,100nm. Both of these bands of wavelength are thought to act upon the mitochondria to stimulate ATP (the energy molecule) production. Although this would seem counter to sleep, red and NIR light has been shown to increase the production of melatonin outside of its traditional synthesis within the pineal gland. It is thought that this is related to melatonin's role in helping to protect the mitochondria from radical oxygen species.1,2
Red light has also been shown to help reset the circadian rhythm alongside its ability to increase melatonin synthesis and promote sleep.3,4
Can't stop scrolling?
Do you find yourself scrolling mindlessly late into the night? Blue light emitted from our devices not only disrupts our circadian rhythm but tech in the bedroom can also leave your immune system in a state of alertness. This heightened alertness contributes to a racing mind and sleep anxiety. This means we potentially miss the 'sleep gate' i.e. the time slot suitable for sleep. Studies have shown that not only does smartphone use affect readiness for sleep but can also negatively affect alertness come morning. In addition, buzzes or other signals from smartphones, such as the screen lighting up for a notification will impact your sleep quality. 1 
The best practice to improve your sleep quality and help you drift off to sleep easier is to avoid device use at least 2 hours before sleep, and avoid use in the bedroom completely. If you really can't resist that last TikTok reel (and we really do suggest that you try!) our deep sleep pillow spray is proven to help people fall asleep faster and have a better quality of sleep even when tested on 100 heavy tech users.
