Why Waking Up At 5 AM Feels Easier Than 7 AM: Many people assume that sleeping longer automatically means waking up fresher. But if you’ve ever woken up at 7 AM feeling more tired than at 5 AM, you’ve already experienced how tricky the body’s sleep cycles can be.
Your body doesn’t just drift in and out of sleep randomly; it follows 90-minute sleep cycles, moving through light sleep, deep sleep, and REM (dreaming) stages. When you wake up at the wrong point in this cycle, especially during deep sleep, you’re likely to feel groggy, sluggish, and annoyed, no matter how many hours you’ve slept.
Why Waking Up at 5 AM Can Be Better Than 7 AM
Aligned with Sleep Cycles: If your natural cycle ends around 5 AM, waking then means you’re coming out of lighter sleep, making it feel easier. By 7 AM, you may already be back in a deeper stage, making it harder to wake.
Circadian Rhythm Advantage: Your body’s internal clock peaks in alertness just after sunrise. Waking earlier often syncs you better with natural light and hormone release (like cortisol), giving you an energy boost.
Fewer Sleep Inertia Symptoms: Sleep inertia, the grogginess you feel upon waking, is shorter when you rise at the end of a cycle, which often aligns better with 5 AM than later wake times.

The Role of Circadian Rhythms
Circadian rhythm is your body’s 24-hour clock that controls sleep, hormones, and alertness. Melatonin (the sleep hormone) peaks at night, while cortisol (the “wake-up” hormone) rises with daylight.
If you sleep early enough, waking at 5 AM aligns beautifully with this rhythm, leaving you fresh and focused. But if you sleep late and push wake-up to 7 AM, your cycle gets disrupted, causing you to wake mid-cycle and feel drained.

How to Wake Up Energised Every Day
1. Track Your Sleep Cycles: Aim for 7.5 or 9 hours of sleep (5–6 complete cycles) instead of obsessing over wake-up times.
2. Sleep Earlier: Sleeping by 10 PM makes a 5 AM wake-up natural and effortless.
3. Use Light Exposure: Open curtains or use natural light to signal your body to wake up.
4. Be Consistent: Waking at the same time daily strengthens your circadian rhythm.
The Bigger Lesson
It’s not about whether 5 AM is “better” than 7 AM, it’s about aligning your wake-up time with your natural cycles. Once you master this, you’ll unlock mornings full of energy, productivity, and clarity.
