Since 2004, This Works has pioneered research into sleep science, neurocosmetics and the brain-body connection. Working with neuroscientists including Professor Gaby Badre and Swedsleep Sweden, the brand has funded six independent sleep studies involving 900+ participants alongside fMRI, EEG and polysomnography research exploring how fragrance affects mood, memory and sleep. This work informed the development of the Deep Sleep Functional Fragrance of Lavender, Vetivert and Wild Camomile - a clinically informed fragrance designed to support circadian rhythm, evening calm and overnight recovery.

FAQs
Do pillow sprays actually help you sleep?
Yes. A well-formulated pillow spray can support sleep when used alongside good sleep hygiene and consistent night-time habits. This Works Deep Sleep Pillow Spray uses a clinically proven Functional Fragrance with Lavender, Vetivert and Wild Camomile, tested through independent user studies and clinical trials to help improve sleep quality. The calming scent signals to the nervous system that it is time to wind down, supporting natural circadian wind-down cues.
How long does a This Works pillow spray last?
A This Works pillow spray should last several weeks to months, depending on how many times a night and the number of beds it is used on. Typically if used nightly on just your bed sleep plus pillow spray lasts around 3-4 weeks for 50ml and 5-8 weeks for 100ml. Deep sleep pillow spray lasts around 4-6 weeks for 75ml, 3-5 months for 250ml and 6+ months for 400ml. Use 1–2 sprays nightly as part of your sleep routine.
What is the best sleep routine to follow?
A good sleep routine should be simple, consistent and repeated nightly. Begin 30–45 minutes before bed with a Deep Sleep bathing product, then layer Deep Sleep bodycare to dose the Functional Fragrance throughout your routine, helping ease the transition from stimulation to relaxation. At bedtime, choose the pillow spray that matches your sleep concern: Deep Sleep to help you fall asleep faster, or Sleep Plus to help you stay asleep for longer.
Are This Works sleep products safe during pregnancy?
Many This Works sleep products are suitable during pregnancy, including deep sleep pillow spray and sleep plus pillow spray. However, deep sleep bath oil and any retinoid-containing products, such as my wrinkles midnight moisture, are not recommended during pregnancy due to essential oil concentration or Vitamin A derivative content. Always check the pregnancy guidance on each product page before use and, if you are unsure, consult your midwife, GP or healthcare professional.
What is the difference between Deep Sleep and Sleep Plus?
Deep sleep pillow spray is designed to help you fall asleep faster, with an immediate-release Functional Fragrance of Lavender, Vetivert and Wild Camomile. Sleep Plus Pillow Spray is designed to help you stay asleep for longer, using motion-activated fragrance technology that releases the same proven fragrance as you toss and turn. Choose Deep Sleep if you struggle to drift off, and Sleep Plus if you tend to wake during the night.
How do I fix my sleep schedule?
To help reset your sleep schedule, keep a consistent wake time, get morning light exposure and reduce bright light and screens before bed, as light helps regulate melatonin and the body clock. Build a repeatable pre-sleep routine with a warm bath, Deep Sleep bodycare and a pillow spray chosen for your sleep concern. This Works products can support circadian alignment, but they do not replace good sleep hygiene and consistent behavioural habits.
Is This Works cruelty free?
Yes. This Works is cruelty free and proud to be part of PETA’s Beauty Without Bunnies scheme. We never test our products or ingredients on animals, and every formula is assessed by independent human toxicologists before launch. Vegan and vegetarian suitability varies across our sleep, skincare, bodycare and fragrance ranges, so please check each product page for the most accurate guidance.
