Sleep Tracking and Melatonin Benefits:
The Great Sleep Experiment

Sleep is one of the most important pillars of recovery, cognitive performance, and overall
health. Yet millions of people sleep for eight hours and still wake up tired.

The problem is often not how long you slept, but how well you slept.

Deep sleep, REM cycles, oxygen levels, heart rate variability, and circadian rhythm
alignment determine how recovered you actually feel. Poor sleep quality can impact stress,
focus, immunity, hormonal balance, and long-term performance.

As sleep tracking technology becomes more accessible, it is now possible to measure sleep objectively instead of relying on how we “feel.”

This raises an important question:

Can sleep supplements actually improve measurable sleep quality?

At Be., we wanted to move beyond promises.

We wanted proof.

In partnership with LUNA, our technology and measurement partner, we launched The Great Sleep Experiment, a real-world initiative combining Be. On DND with the Luna Ring to track sleep quality using objective biometric data.

The experiment focused on one core belief:
If sleep improves, the data should show it.

What Is The Great Sleep Experiment?

The Great Sleep Experiment is a two-week sleep optimisation initiative designed to measure measurable changes in sleep quality using sleep tracking technology.

Participants: 8
Duration: 2 weeks
Structure:

• Week 1: Baseline sleep (unsupplemented)
• Week 2: Supplemented sleep (with Be. On DND)

Participants used the Luna Ring, a wearable sleep-tracking device, to monitor sleep performance before and after introducing supplementation.

Unlike a controlled lab study, this experiment reflected real lifestyles — work stress, late
nights, inconsistent schedules.

We did not control participants’ environments. The only guidance provided was:

• Follow basic sleep hygiene
• Try maintaining a wind-down routine
• Avoid alcohol before bed where possible

This made the results more relevant and actionable in real-world conditions.

Why Sleep Quality Matters More Than Sleep Duration

Most people judge sleep based on hours. But true recovery depends on sleep architecture.

Deep sleep supports:

• Physical repair
• Immune recovery
• Hormonal regulation

REM sleep supports:

• Cognitive recovery
• Memory consolidation
• Emotional regulation

Recovery happens when the body cycles efficiently through these stages. Eight hours of
fragmented sleep can be less restorative than six to seven hours of high-quality sleep.

That is why sleep tracking matters. It reveals not just how long you slept, but how well your body recovered.

The Experiment Structure: Baseline vs Supplementation

To ensure measurable comparison, the experiment was divided into two distinct phases.

Week 1: Baseline Sleep (Unsupplemented)

Participants completed one full week of habitual sleep without using Be. On DND. This
established a true baseline across key sleep and recovery metrics.

The Luna Ring tracked:

•  Sleep score and readiness
•  Deep sleep and REM sleep percentage
• Total sleep duration
• Resting heart rate
• Heart Rate Variability (HRV)
• Oxygen saturation (SpO2)
• Circadian rhythm alignment
• Sleep interruptions and fragmentation

This baseline allowed us to identify individual sleep gaps and understand natural sleep
patterns.

Week 2: Supplemented Sleep with Be. On DND

In the second week, participants consistently introduced Be. On DND into their nightly
routine.

All metrics continued to be tracked using the Luna Ring, allowing direct comparison between unsupplemented and supplemented sleep.

By measuring two consecutive weeks under real-life conditions, we were able to:

• Compare baseline vs supported sleep
• Identify changes in sleep depth and recovery
• Quantify improvements in measurable sleep performance

The results were observed, not assumed.

The Role of LUNA and the Luna Ring

To ensure accuracy and consistency, Be. partnered with LUNA as the official technology
partner for The Great Sleep Experiment.

The Luna Ring provided continuous, non-invasive tracking of:

• Sleep score and readiness
• Deep sleep and REM sleep percentage
• Sleep duration and interruptions
• Resting heart rate and HRV
• SpO2 levels
• Circadian alignment
• Recovery and Readiness index

This allowed us to directly link supplementation with measurable biometric outcomes.

Be. On DND and Sleep Support

During the second week of the experiment, participants introduced Be. On DND into their
nightly routine while maintaining their usual habits.

Be. On DND is formulated to support the full sleep cycle — not just falling asleep, but staying asleep and recovering deeply.

Key ingredients include:

• Melatonin – Supports circadian rhythm regulation and sleep onset
• Magnesium – Promotes muscle relaxation and supports deep sleep quality
• Ashwagandha – Helps regulate stress and cortisol levels
• Chamomile – Traditionally used to calm the nervous system

Together, these ingredients support sleep induction, sustained sleep, nervous system
relaxation, recovery, and waking up refreshed.

Key Sleep Improvements Observed

When comparing baseline sleep to supplemented sleep across 8 participants, the
experiment showed measurable improvements in core sleep health markers.

• Resting heart rate decreased by an average of 3.72 percent
• Deep sleep duration increased
• Oxygen saturation (SpO2) improved
• REM sleep increased across multiple participants
• Sleep fragmentation reduced
• Overall sleep scores improved

These markers are directly associated with improved recovery and reduced physiological
stress.

Individual Sleep Results

At a participant level, improvements were both measurable and meaningful.

• One participant increased deep sleep from 16.78 percent to 18.86 percent, along
  with improved SpO2 levels
• Another improved sleep score from 67.2 to 92, gaining two additional hours of sleep per night
• A third recorded a 3.3 percent increase in REM sleep and 1.5 additional hours of
  sleep
• Multiple participants showed gains in both deep sleep and REM sleep
  

Beyond numbers, participants experienced more stable and less fragmented sleep patterns.

Gender-Based Sleep Insights

Data from the Luna Ring also revealed gender-specific trends.

Women experienced:

• A 4.69 percent increase in REM sleep
• Lower resting heart rates

Men showed:

•  Deeper sleep phases
•  A 5.75 percent increase in SpO2

These findings highlight the importance of personalised sleep optimisation.

Quick Takeaways

• Sleep quality matters more than sleep duration
• Deep sleep and REM sleep drive recovery
• Sleep tracking removes guesswork
• Melatonin supports circadian rhythm alignment
• Magnesium promotes relaxation and deep sleep
• Consistency improves measurable outcomes
• Data-backed sleep optimisation is more effective than assumption

What The Great Sleep Experiment Proves

The Great Sleep Experiment demonstrates that sleep supplements are most effective when
paired with structured tracking and consistency.

By establishing a baseline week and directly comparing it to a week of supported sleep with Be. On DND, we moved from subjective claims to objective measurement.

Sleep optimisation works best when supplementation meets data.

Frequently Asked Questions

Is sleep quality more important than sleep duration?
Yes. Recovery depends on deep sleep and REM cycles, not just hours slept.

Does melatonin improve sleep quality?
Melatonin supports sleep onset and circadian rhythm alignment. When paired with relaxation-supporting nutrients like magnesium and ashwagandha, overall sleep quality may improve.

How does magnesium help with sleep?
Magnesium supports nervous system regulation and deeper sleep stages.

Do sleep supplements improve REM sleep?
When stress and circadian disruption are reduced, REM sleep can improve. This experiment showed measurable REM increases.

Do I need sleep tracking?
Sleep tracking helps identify gaps in recovery and sleep architecture, allowing more precise optimisation.

The Future of Sleep Optimisation

Sleep does not need to be a mystery.

Wellness should not rely on guesswork.

The Great Sleep Experiment sets a new standard for evaluating sleep supplements; measured, transparent, and backed by real biometric data.

Better sleep is not just about feeling rested.

It is about understanding your body and optimising it intelligently.
