Sleep can transform our lives.
Our lives can transform sleep.

A third of people in developed nations – and close to 40% of Japanese – are concerned about their sleeping
patterns. In Japan alone, lack of sleep is estimated to cost the economy ¥3.5 trillion yen [each year],
with ¥3.2 trillion of this attributable to the resulting decline in productivity.
Many people do not realize that a lack of sleep is having a negative impact on their performance.
Sleepdays helps you to restore your performance to its former glory.

A World First:
Introducing the
Circadian Sleep™ Method.

A Groundbreaking Method That Fuses Somnology* and Chronobiology
When our circadian rhythm (internal clock) is disrupted, we experience not only a reduction in the quality of our sleep, but also a decline in our performance throughout the day. Disruptions can also impact our efficiency at work, diet, and efforts to improve our physical condition. The Circadian Sleep™ Method analyses your circadian rhythm through your sleeping patterns, and makes recommendations throughout the day on how best to time your activities. These recommendations support you in restoring your circadian rhythm to a healthy state. Informed lifestyle decisions throughout the day lead to high quality sleep, and high quality sleep leads to an increase in the quality of your performance throughout the day.

Know Yourself.

Not just by analyzing your sleep every day,
but also by understanding your habits.

Sleep Analysis
By unique analysis algorithms, Sleepdays is capable of assessing the quality of your sleep to a high level of accuracy. It also allows you to examine the finer details of this analysis, such as time taken to fall asleep and sleep efficiency.
Rhythm Check
Circadian rhythms cannot be understood in a single day. Through continuous daily use, Sleepdays allows you to identify the characteristics of your own circadian rhythm, as well as any irregularities in your internal clock.
