Scientific sound technology for the SmartPillow by Cambridge Sleep Sciences. Welcome to SleepEngine™ – the App which powers the Cambridge Sleep Sciences SmartPillow and enables you to enjoy better sleep using scientifically developed sound technology. Whether you suffer from insomnia, work alternative shift patterns, wake frequently during the night or are looking to optimise sleep for better physical and mental performance, SleepEngine™ technology can help improve your sleep and enhance your health and wellbeing. WHAT IS SLEEPENGINE™ TECHNOLOGY? This unique technology uses a neuroscientific approach to create sound waves which match the waves created by the adult brain during healthy sleep cycles. When any of the SleepEngine™ Sleep Programs are played, the sound waves (we call them Sleepsounds) guide your brain through the correct sequence of healthy sleep cycles so you can fall asleep quicker, stay asleep for longer and improve the overall quality of your sleep. Poor sleep habits, lifestyle factors and other circumstances can disrupt healthy sleep patterns. Over time, your brain can forget the correct sequence of patterns and this is where difficulty falling and staying asleep can take hold. SleepEngine™ has been developed to retrain your brain to restore natural sleep patterns. And this all happens while you sleep! HOW IT WORKS The high quality pillow contains a small unit with two speakers inside. The SleepEngine™ App connects the unit to your smart device using Bluetooth. The App controls the unit and enables you to easily play your chosen Sleep Program, optional Soundscape and set your alarm, if required. When playing the Sleepsounds, you will hear low frequency tones which guide you into sleep and encourage your brain to follow the sequence of healthy sleep cycles. When your chosen Sleep Program ends, you will wake up at the right point in the sleep cycle, refreshed and energised from improved sleep quality. Regular and repeated use of SleepEngine™ will help to retrain your brain to produce the right sequence of sleep cycles and restore natural healthy sleep patterns. PROVEN TECHNOLOGY In two independent trials of the SleepEngine™ technology, featured in the SleepHub® sleep aid, 92%+ of users saw a positive improvement in their sleep and experienced on average per night, up to 2.5 hours more time per sleep per night and up to 1.5 less waking times. SleepEngine™ technology, used in the SleepHub® sleep aid, has also received many positive reviews from the media and consumers around the world. CHOICE OF SLEEP PROGRAMS & SOUND FEATURES The SleepEngine™ App controls all the sound technology features of the SmartPillow. Once the App has been connected to the SmartPillow, you can personalise your sleep experience by choosing your preferred sleep settings. By experimenting with different settings, you can discover which ones help you to best fall asleep and stay asleep throughout the night. There are 4 Sleep Programs to choose from: Deep Sleep: a recommended 8-hour program which includes an 18 minute wake-up cycle and alarm Easy Sleep: choose 2 to 8 hours of sleep when you don’t have enough time for the Deep Sleep program Fall Asleep: a 2 hour program which guides you into deep sleep; ideal for those who struggle to get to sleep Power Nap: provides an energising nap for 30, 45 or 60 minutes You can further customise your sleep experience by playing relaxing and calming Soundscapes alongside the Sleepsounds. Choose from Ocean, Rain, Stream, Wind, Train and White, Pink and Brown Noise. You can also set your preferred alarm sound from a selection of smooth and energetic options which enable you to wake up in the mood that suits you most. Sound controls enable you to adjust your volume and balance levels, to ensure you achieve the optimal sleep experience using the SleepEngine™ technology.
