If you wear a sleep tracker, you already know the feeling. You went to bed at a reasonable hour, you slept through the night, and you wake up to a score that tells you it wasn't enough. Low deep sleep. Poor readiness. A body battery that barely moved.

You're not alone in that experience. Two out of three adults wake up feeling rested only once or twice per week. One in three aren't getting enough sleep at all. The response most people reach for is melatonin - and use of it has increased 425% over the last five years - but melatonin addresses when you fall asleep, not the quality of sleep you get. For someone watching their deep sleep numbers, that distinction matters.

The good news is that sleep scores aren't fixed. They're a reflection of your biology responding to real inputs, and most of those inputs are within your control. Here's what actually moves the needle.

What Is a Sleep Score, Really?

Before getting into the tips, it's worth understanding what your wearable is actually measuring. Whether you use an Oura Ring, Whoop, Garmin, or another device, sleep scores are typically a composite of several metrics:

• Total sleep time: How many hours you were actually asleep versus in bed
• Sleep efficiency: The percentage of time in bed spent sleeping
• Sleep stages: How much time you spent in light sleep, deep sleep (slow-wave sleep), and REM
• Resting heart rate and heart rate variability (HRV): Indicators of how recovered your nervous system is
• Restlessness: How often you moved or woke during the night

Deep sleep, in particular, carries heavy weight in most scoring algorithms. It is the stage where physical restoration happens, growth hormone is released, and your brain consolidates memory and clears metabolic waste. When your deep sleep is low, your score is low, even if your total sleep time looks fine on paper.

9 Tips to Improve Your Sleep Score

1. Keep a Consistent Sleep and Wake Time

Your circadian rhythm is the master clock that governs nearly every biological process in your body, including when you cycle through sleep stages. Irregular sleep timing throws that clock off, reducing the efficiency and depth of your sleep even when you get a full night.

The most impactful change most people can make is choosing a consistent wake time and protecting it, even on weekends. Your bedtime will naturally self-regulate from there. Trackers tend to reward consistency quickly because HRV and resting heart rate both stabilize when your circadian rhythm is well-anchored.

2. Get Morning Sunlight as Early as Possible

Light is the primary signal that sets your circadian clock. Exposure to natural light in the morning, ideally within 30 to 60 minutes of waking, triggers a cortisol pulse that promotes alertness and starts the countdown to melatonin production later in the evening.

This isn't just a habit tip. Studies show that consistent morning light exposure measurably shifts sleep onset earlier and increases the proportion of slow-wave (deep) sleep in the first half of the night. The effect is stronger with actual outdoor light than indoor lighting, even on overcast days.

3. Protect Your Sleep Environment

Your tracker can tell you when you're restless, but it can't fix the conditions causing the restlessness. The three most important environmental factors are temperature, light, and noise.

Temperature: Core body temperature needs to drop 1 to 2 degrees Fahrenheit to initiate and sustain deep sleep. Most research points to a bedroom temperature between 65 and 68 degrees Fahrenheit as optimal. If your deep sleep is consistently low, temperature is the first environmental variable worth adjusting.

Light: Even low-level light during sleep, including standby lights on electronics, has been shown to reduce sleep quality and increase next-day insulin resistance. Blackout curtains or a sleep mask make a measurable difference for many people.

Noise: Intermittent noise (traffic, a partner's movement, notifications) fragments sleep without always fully waking you, suppressing deep sleep in ways you won't consciously register. White noise, earplugs, or a fan can buffer against this.

4. Limit Alcohol, Even in Small Amounts

This is one of the most consistent findings in sleep science and one that wearable users discover quickly. Alcohol is sedating, but it is not sleep-supporting. It suppresses REM sleep in the second half of the night, fragments sleep as it metabolizes, and raises heart rate in ways that directly lower HRV-based recovery scores.

Even one to two drinks in the evening produces a measurable drop in most sleep trackers the next morning. If you're trying to improve your score, alcohol timing and quantity are worth examining honestly.

5. Time Your Exercise Strategically

Regular exercise is one of the most reliable ways to increase deep sleep over time. But timing matters. Vigorous exercise raises core body temperature and stimulates the sympathetic nervous system, both of which can delay sleep onset if the workout happens too close to bedtime.

For most people, finishing intense exercise at least two to three hours before bed is the practical guideline. Morning or early afternoon workouts tend to produce the most favorable effects on that night's sleep architecture. If evenings are your only option, lower-intensity movement like yoga or walking is less disruptive than high-intensity training.

6. Manage Evening Stress and Wind Down Deliberately

HRV is a direct measure of how well your autonomic nervous system has recovered from the demands of the day. Stress, whether from work, a difficult conversation, or something you're anxious about, activates the sympathetic nervous system in ways that suppress HRV and suppress deep sleep.

A deliberate wind-down routine in the 30 to 60 minutes before bed helps shift your nervous system from sympathetic (alert, reactive) to parasympathetic (calm, restorative). This doesn't need to be elaborate. Dimming lights, avoiding screens, light reading, breathwork, or a warm bath or shower can all signal to your body that the day is over. The drop in body temperature after a warm bath, in particular, has been shown to accelerate sleep onset.

7. Watch Your Caffeine Window

Caffeine has a half-life of five to seven hours, which means half of the coffee you drank at 2:00 PM is still circulating at 9:00 PM. For many people, an afternoon cutoff of 1:00 to 2:00 PM is the practical threshold to protect sleep quality, though individual caffeine metabolism varies.

Late caffeine doesn't always prevent you from falling asleep, but it does reduce the proportion of deep sleep you get, which is exactly what shows up as a lower score. If your sleep score is consistently underperforming relative to your total sleep time, caffeine timing is worth experimenting with.

8. Address Sleep Debt Strategically

Sleep trackers are particularly good at revealing accumulated sleep debt, the cumulative deficit that builds when you routinely sleep less than your body needs. Recovery from sleep debt isn't immediate, and you can't fully repay weeks of short nights in one long weekend.

The more sustainable approach is raising your nightly floor. Getting even 30 additional minutes per night on a consistent basis has measurable effects on next-day HRV, recovery scores, and deep sleep proportion over several weeks. Prioritizing an earlier bedtime rather than a later wake time tends to work better because it adds sleep in the first half of the night, where deep sleep is most concentrated.

9. Give Your Body the Right Ingredient for Deep Sleep

The tips above are about conditions: light, temperature, timing, stress, and substances. But sleep quality also depends on what's happening at the biochemical level, and that's where most people hit a ceiling. You can do everything right environmentally and still struggle with deep sleep if your body's internal signaling isn't supporting it.

PeptiSleep is a plant-based peptide derived from brown rice, developed by Nuritas using AI-driven research into bioactive compounds. It works by reducing cortisol, the hormone that keeps you alert and is one of the primary biological barriers to falling into deep sleep. In Nuritas's studies, participants experienced:

• 61% faster sleep onset
• 13 more minutes of deep sleep
• 12 more minutes of REM sleep
• 38 additional minutes of total sleep time per night
• 32% higher HRV

This is the kind of data that matters to someone who tracks their sleep. Not "feel more rested" -- actual measured changes in sleep architecture, the same metrics your wearable is scoring every morning.

Brik Sleep Gummies are built using the full, clinically studied dose of PeptiSleep as the active ingredient. They're melatonin-free, non-habit forming, and designed to be taken 30 minutes before bed as part of your nightly routine. If you're serious about your sleep data, this is worth adding to your stack.

Melatonin-free. Clinically studied. Non-habit forming.

How Long Does It Take to Improve a Sleep Score?

This is the question every tracker-wearer wants answered. The honest answer is that it depends on which variable you're targeting.

Alcohol removal, consistent wake time, and temperature optimization often show measurable changes within a few days to a week, because your tracker is sensitive enough to capture immediate physiological responses.

Deeper changes, like improving baseline HRV, increasing the proportion of deep sleep, or resolving chronic sleep debt, take several weeks of consistent behavior. Wearable users who stick with a new sleep routine for 30 days typically see more meaningful shifts than those who try one change for a few nights and give up.

Track one variable at a time when possible. Your device is doing the work of measuring for you. Give the experiment enough time to produce a signal.

The Bottom Line

A low sleep score is information, not a verdict. It reflects inputs that are within your control: light, temperature, timing, stress, substances, and the biological conditions you're giving your body to work with each night.

The behavioral tips in this list address most of those inputs. But there's one layer they can't reach: the internal biochemistry that governs how deeply and how long you sleep once you're in bed. That's where PeptiSleep comes in.

Brik Sleep gummies are built around PeptiSleep, which specifically addresses what wearables actually measure. Not sedation. Not sleep onset alone. Deep sleep, REM, total sleep time, and HRV -- the numbers on your screen every morning. In a clinical pilot, participants added 13 minutes of deep sleep, 12 minutes of REM, 38 minutes of total sleep, and saw a 32% increase in HRV. Melatonin-free, non-habit forming, and designed to be part of a nightly routine that your tracker will notice.

If you're doing the work to sleep better, Brik is how you help that work pay off.
