What Makes Us Sleepy?
Understanding Melatonin and Sleep Cycles

Melatonin, often referred to as the “sleep hormone,” plays a vital role in regulating your natural sleep–wake cycle. As daylight fades and evening approaches, your body begins to increase melatonin production, signaling it’s time to wind down. Levels typically peak around midnight and remain elevated until about 3:00 AM, helping to maintain deep, restorative sleep. After this peak, melatonin production slowly decreases, gently prompting your body to transition toward morning wakefulness.

To support this natural process, a low-dose melatonin supplement, such as Calm Melatonin 3mg, taken at 8 PM can enhance melatonin levels in your brain. This gentle boost works in harmony with your body’s natural production, helping you fall asleep more easily and stay asleep throughout the night.

But why choose 3 mg instead of higher doses like 10 mg or 20 mg? Research shows that oral melatonin supplementation can increase your body’s natural melatonin levels by up to 60 times. Extremely high doses may cause side effects such as anxiety, frequent nighttime awakenings, and persistent daytime drowsiness—all of which interfere with restorative sleep.

Your brain’s melatonin production is also closely tied to light exposure. Natural sunlight during the day signals your brain to delay melatonin production until darkness, keeping your sleep cycle aligned with the environment. However, insufficient sunlight during the day or too much artificial light (especially from screens) after sunset can delay melatonin release, making it harder to fall asleep.

To support healthy melatonin rhythms, try increasing your morning light exposure. Using a therapy light for 15–30 minutes while getting ready can be especially beneficial during the winter months in northern states. This simple habit can help reset your internal clock and improve overall sleep quality.

What Steps Can I Take to
Get More Sleep?

Improving your sleep quality often starts with simple but impactful lifestyle changes. Here are two effective strategies to help you sleep better—along with a few product recommendations to support your nighttime routine.

1

Avoid Alcohol Before Bedtime

While alcohol may seem to help you unwind, it actually disrupts critical sleep stages, especially REM sleep, leading to poor sleep quality and next-day fatigue. Reducing or eliminating alcohol in the evenings can significantly improve how deeply and restoratively you sleep.

Recommendations:

If alcohol is interfering with your ability to get restorative sleep, consider speaking with a healthcare professional for personalized support.

2

Eliminate Caffeine After 12 PM

Caffeine can affect your ability to sleep for up to 16 hours after consumption. Reducing your daily intake—and avoiding caffeine after noon—can help regulate your natural sleep–wake cycle and improve both the quality and duration of your rest. Even small adjustments, like replacing your afternoon coffee with a caffeine-free option, can make a big difference.

Recommendations:

Once you’ve reduced stimulating habits, incorporating calming rituals before bed can help signal your brain that it’s time to wind down.

  • Tryptophan is the building block of serotonin and melatonin.
  • Melatonin helps regulate your sleep cycle, and serotonin supports feelings of calm.
  • Warming the milk encourages slow sipping, which is soothing in itself.
  • The protein in milk can help stabilize blood sugar levels overnight, supporting uninterrupted sleep.
  • Skip chocolate milk at night—its caffeine can interfere with your rest.

To reduce blue light exposure:

  • Turn on night mode or “warm light” settings on your devices from sunset to sunrise.
  • Wear blue light–blocking glasses in the evenings.
  • Avoid scrolling right before bed whenever possible.

How to enable night mode on your devices:

  • iPhone: Settings → Display & Brightness → Night Shift
  • Android: Settings → Display → Night Light or Eye Comfort
