TrueDawn technology wakens you exactly as nature intended by gradually increasing light just like a
summer sunrise. Th
is signals your body to complete its sleep cycle so you awaken when you need to,
feeling refreshed and ready to start the day. TrueDawn synchronizes your sleep/wake cycle—helping you
wake and sleep better.
Just like sunrise, TrueDawn follows a sigmoidal light curve—the right type of increasing intensity—
which signals the body clock without causing premature awakening. Other “dawn simulators” employ
an inexpensive linear ramp-up, which can cause premature awakening and is ineff ective at regulating the
body clock. When you use your Daybreak, you’ll awaken much easier than ever before with more energy
to start the day.

delaying alertness.

slowly at first, allowing a gradual awakening.
TrueDawn ™ Sunrise Clock: The Daybreak’s
