Sleep Is Not Just About Hours. It’s About Timing.
Many people think sleep problems are caused by stress or bad habits, but understanding your sleep timing helps you work with your body instead of against it.
• Know When Your Body is Ready for Sleep
• Make Smarter Schedule Adjustments
• Improve Consistency Over Time
Who Is This Test For?
Shift Workers and Irregular Schedules
If your work hours change or fall outside traditional schedules, knowing your natural rhythm can help you plan sleep more strategically.
Night Owls and Early Birds
If you feel naturally alert very late at night or very early in the morning, your internal timing may be shifted.
Frequent Travelers or Schedule Adjusters
If travel or time changes regularly disrupt your sleep, understanding your rhythm can make adjustments easier.
What Can You Learn?
Our tests measure when your body begins producing melatonin in the evening.
That timing shows when your body is biologically ready for sleep.
Your results can help you understand:
• Your Natural Sleep Window
• If Your Schedule is Aligned With Your Biology
• How to Adjust Sleep Timing More Effectively
• Your Optimal Biological Bedtime
