Most people think of sleep preparation as something that happens in the hour before bed. But sleep expert Nancy Rothstein, in her work with Resonea, makes a compelling case that the quality of your night actually begins the moment you wake up.
Your circadian rhythm — the internal biological clock that governs your sleep-wake cycle — is influenced by everything you do throughout the day. From your morning light exposure to your caffeine habits, afternoon exercise to evening screen time, every choice either supports or sabotages the sleep you will get that night.
How Your Day Shapes Your Night
- Morning Light Exposure: Getting natural sunlight within the first hour of waking helps set your circadian clock for better sleep that night
- Caffeine Timing: Caffeine consumed even in the afternoon can linger in your system and disrupt sleep cycles hours later
- Physical Activity: Regular exercise supports deeper, more restorative sleep — but timing matters, as vigorous activity too close to bedtime can be stimulating
- Stress Management Throughout the Day: Unmanaged stress accumulates and often manifests as racing thoughts at bedtime
- Evening Wind-Down: The transition from day to night is critical — reducing blue light exposure and creating a calming pre-sleep routine signals your brain that rest is coming
Nancy, who served as Director of Sleep Health at Resonea, brings a wealth of clinical and practical experience to this perspective. The key insight is empowering: you have far more control over your sleep quality than you may realize, and it starts from the moment your eyes open in the morning.
