Begin your journey to better sleep, more energized days, sharper focus and improved mood with TUO Circadian Smart Lighting. TUO is partnered with the University of Washington, one of the world's top research centers for vision and neuroscience. Scientists there have recently discovered amacrine cells in the eye. These highly light-sensitive cells are the cells that TUO's patented, industry-leading technology affects to influence your circadian rhythm. TUO is more effective than anything else on the market and is the only circadian light therapy product that works at normal brightness levels and reasonable distance. Put TUO bulbs in your bedroom to get exposure when first waking. Put TUO bulbs in your bathroom to get exposure during your normal morning routine. Put TUO bulbs in your kitchen, and make your family breakfast while getting exposure. Put TUO bulbs on your desk, and check email while taking in light. With TUO, you need to stay within six feet of your light during the majority of your Wake mode. After that, you don't need to worry. Just continue your daily routine, and get the light that you need. Artificial lighting isn't healthy. Our bodies receive signals from the lighting around us. These signals set our internal clocks and regulate when we naturally sleep and wake. When we're exposed to general home and work lighting, we don't get the signals that we need to keep our biological schedule synchronized with our daily schedule. Circadian rhythm disorders are problems that occur when your body's internal clock is out of sync with your environment. Symptoms include excessive sleepiness, insomnia, reduced alertness, impaired decision making, poor school/work performance, elevated stress, inability to meet social obligations, changes in appetite and gastrointestinal function, reduced cardiovascular performance, reduced libido, substance abuse, weight gain, high blood pressure and depression. Prolonged misalignment between your biological schedule and your daily schedule puts you at higher risk for heart disease, obesity, diabetes, gastrointestinal problems, neurodegenerative disorders including dementia, skin issues and more. TUO Circadian Smart Products synchronize your biological schedule to your daily schedule by providing the light signals your mind and body need throughout the day. The TUO Life App sets a customized schedule based on your age, chronotype and general wake and sleep times so that you can set it and forget it. TUO Circadian Smart Bulbs change to the right mode at the right time automatically and can be used in any room. Our morning WAKE mode will give you a boost of energy to kickstart your day. Our all-day ACTIVE mode will keep your focus sharp throughout the day. Our evening CALM mode will help you wind down and fall asleep naturally. GETTING STARTED Launch our app and click sign up to get started. Follow the instructions on the screen to walk through initial setup and add your bulbs. You'll be asked to allow the app permissions throughout the setup process. Make sure you allow all permissions as we won't be able to setup your bulbs without them. Add your family members so that they can benefit from TUO as well. When you add family members, our app generates a customized circadian schedule for them. You can give them app login rights or control bulbs on their behalf. You can also assign them rooms so that those rooms always run on their schedule. Add on/off schedules to fully automate your TUO experience. On/off schedules let your bulbs automatically come on and turn off throughout the day. These can be configured for individual rooms and can be different for different days of the week. This allows your lights to automatically come on when you want them to. Use the app to turn rooms and individual devices on and off. Change your light brightness and color temperature to match your preferences. Override your circadian modes at any time. How you use TUO is solely up to you.
