Your Body Is Tired. Why Is Your Mind Still Awake?

Did you know that 74% of American adults reported that stress disrupted their sleep at least sometimes? That finding comes from the American Academy of Sleep Medicine’s 2024 survey, released in 2025. ¹

You know the feeling. You’re exhausted. You get into bed. Then your brain starts working through tomorrow’s schedule, yesterday’s conversation, and everything you haven’t finished.

Being tired and being ready for sleep can feel like two different things.

What’s keeping you awake?

Stress and worry can make it harder to settle down. Hormonal changes during menopause or pregnancy, irregular schedules, late caffeine, and evening screen use can also interfere with sleep. There isn’t one explanation for everyone. ²

Understanding what keeps you awake is the first step toward a better night.

Melatonin is a hormone

Your brain naturally makes melatonin in response to darkness. It helps tell your body when nighttime has arrived. Supplements can help with certain body-clock problems, including jet lag. But they don’t automatically address racing thoughts, stress, or the other reasons sleep can be difficult. ³

And a common claim needs correcting: studies have not shown that taking melatonin makes your body stop producing its own. Longer-term safety still needs more research. ^3,4

Helping your body wind down

Your central nervous system includes your brain and spinal cord. Your peripheral nervous system connects them to the rest of your body. Within that network, the parasympathetic branch helps support functions associated with rest. During non-REM sleep, heart rate and blood pressure generally fall. ⁵

For an everyday bedtime routine, the goal is simple: give your mind and body time to settle.

That is the thinking behind Deeper Sleep, our melatonin-free formula designed around relaxation and nighttime support.

Its ingredients include glycine, L-theanine, and magnesium glycinate:

Glycine: Small human studies have explored 3 grams before bed, with promising findings for sleep quality and next-day fatigue. ^6,12

L-theanine: A small trial using 200 milligrams daily found improvements in some measures of sleep, including time to fall asleep and sleep disturbances. ⁷

Magnesium: An essential mineral that supports normal nerve and muscle function. That role alone does not establish that supplementation improves sleep for everyone. ⁸

These studies help explain the ingredient choices. They do not establish that the complete Deeper Sleep formula treats insomnia, increases deep sleep, or directly targets both nervous systems.

What happens while you sleep?

For simplicity, think of sleep in three groups: light sleep, deep sleep, and REM sleep. Clinically, there are four stages because light sleep includes two stages. ⁹

Deep sleep is the slow-wave stage, usually more prominent earlier in the night. REM is a more active brain stage, often associated with dreaming. You cycle through these stages throughout the night, and each contributes to healthy sleep. ⁹

Sleep supports brain function, immune health, and metabolism. Your overnight recovery depends on enough sleep and a healthy balance of stages. ⁵

Your brain has an overnight cleanup system

Scientists study a fluid-based waste-clearance pathway called the glymphatic system. Research, much of it in animals, links sleep-related brain activity with the movement of fluid that helps clear metabolic waste. This means byproducts of cellular activity, rather than simply “dead cells.” Researchers are still working out how the process functions in humans. ¹⁰

Build a better evening

Keep a consistent schedule. Give yourself a quieter wind-down period. Reduce late caffeine and make the bedroom dark and comfortable. Deeper Sleep is designed to fit into that routine. ²

If sleep problems persist, look into the cause. Chronic insomnia and conditions such as sleep apnea deserve appropriate care; cognitive behavioral therapy for insomnia is a recommended first treatment for chronic insomnia. ¹¹

The goal: a calmer evening, room for recovery, and a better start tomorrow.
