Hydrated sleep, trusted by high performers.

How Your Sleep And Habits Influence Testosterone (And How to Fix Them)

There's a reason the top 1% wake up stronger, sharper, and more powerful. They've engineered a pre-sleep system that triggers maximum testosterone production during deep REM cycles. Here's their exact formula.

"Improving sleep quality is associated with meaningful improvements in natural hormone regulation over time. Gains that stack every single night. Elite performers mastered this years ago. Now it's your turn.”

– Science-backed Research from Matt Jones, Head of Nutrition at Cadence

LEVER #1

The hidden testosterone thief sitting around your waist

You train hard. Eat clean. But higher body fat and bad sleep are two huge levers on performance. Especially visceral fat, it lowers testosterone by increasing aromatase activity and driving insulin resistance and inflammation.

Evidence: Weight loss of 5–10% can increase total testosterone by 10–30% in overweight men

LEVER #2

The workout style most linked to higher testosterone

Strength training is one of the most reliable lifestyle tools for improving testosterone.

Evidence: Regular resistance training elevates both acute and baseline testosterone levels, especially large-muscle compound movements and high-intensity interval training. High training volume and progressive overload matter more than specific exercises.

LEVER #3

Sleep less, produce less…

the hormone cost of short nights

Elite performers engineer sleep quality, not just sleep duration. Sleep is one of the strongest behavioural drivers of testosterone.

Evidence: Sleeping only 5 hours per night for one week reduces daytime testosterone by 10–15%. Deep sleep (slow-wave sleep) appears crucial for testosterone release. This is the window most people unknowingly sabotage.

LEVER #4

Under-fueling is a testosterone mistake (even if you eat “clean”)

You're doing everything right. Lean protein. Complex carbs. Vegetables. But if you're chronically under-fueling, your testosterone will pay the price.

Evidence:

Severe calorie restriction reduces testosterone by 20–50%.

Low-fat diets lower testosterone levels by ~10% compared with moderate-fat diets. (Whittaker & Wu, 2021).

Adequate dietary fat (especially monounsaturated fats), protein, and micronutrients like zinc, vitamin D, and magnesium all support healthy levels.

LEVER #5

The weekend habit that quietly drops testosterone

You're disciplined about training. Intentional about nutrition. But at night, you unwind with a drink or two.

Nobody's suggesting you give it up entirely. But not all recovery nights are equal, and what you do before bed matters more than you think.

Evidence: Alcohol suppresses testosterone production at the testicular level. Even moderate but regular intake reduces testosterone. High intake can reduce T by 20–25% for up to 24 hours.

LEVER #6

Your body has two modes. Most high-performers only know how to use one.

Mode 1: Performance

The sympathetic nervous system is active. Cortisol elevated. Mind sharp, body primed.

Mode 2: Recovery

The parasympathetic nervous system is active. Cortisol drops. Testosterone surges. Body rebuilds

Your hormones operate on a 24-hour cycle. Push hard during the day. Then at night, flip the script. The question is: are you actually switching modes, or just hoping your body figures it out?

Evidence: Persistent high cortisol is linked to lower total and free testosterone, impaired libido, and reduced muscle recovery.

LEVER #7

Plastics, pesticides, and testosterone… the daily exposure problem

You control your training. Nutrition. Sleep.

But there's a silent factor most people never consider: environmental endocrine disruptors lurking in everyday items.

They're in your water bottles, food containers, cleaning products, and personal care items.

Elite performers minimize unnecessary exposure:

Use glass or stainless steel instead of plastic

Choose organic produce when possible

Filter water

Avoid heating food in plastic

Evidence: These endocrine disruptors mimic or block hormones, interfering with the cellular machinery responsible for testosterone production and causing measurable suppression even at "normal" exposure levels.

Cadence Recovery: The Sleep Formula That Turns Rest Into Your Competitive Advantage

8 natural ingredients formulated to support deep, restorative sleep that unlocks the performance you've been training for.

SO WHAT DOES THIS ACTUALLY FEEL LIKE?

The first night?

Nothing crazy. Your brain just shuts up faster when you lie down. You're not replaying your entire day on loop. You're just... asleep.

By the end of week 1

You start noticing the difference. You’re sleeping through the night instead of waking up at 2am, 4am, or 6am. When you do wake up, you feel clearer and more alert - without needing coffee right away.

Training feels better too. Stronger. Smoother. Like your body actually has gas in the tank.

Weeks 2-3

This is where it gets real. You hit a PR you’ve been chasing for months. Your legs aren’t constantly sore, and energy stays steady after lunch. People notice: “You seem different.” “You look good.”

What changed? You’re finally recovering properly. Your body is rebuilding the way it’s supposed to.

Training feels better too - stronger, smoother, like you actually have gas in the tank.

Month 2 and beyond

You don’t want to go back.

Sleep used to be something you hoped would go well. Now it’s consistent. Every night, your body knows what to do. You wake up ready. Training compounds. Strength keeps climbing. You’re not just “less tired” anymore. You’re sharper. Stronger. More resilient. More focused.

FAQs

Melatonin is a hormone. When you supplement it directly, your body can become dependent on external sources and may reduce its own production over time. Our formula works differently — it supports your body's natural sleep architecture using amino acids, adaptogens, and minerals that help you fall asleep faster and stay asleep longer, without disrupting your hormonal balance. You wake up clear, not groggy.

Mix one sachet with 250–300ml of water and drink it 30–45 minutes before bed. This gives the active ingredients time to take effect and supports overnight hydration while you sleep. For best results, use it consistently as part of your nightly routine.

No. Unlike sedative sleep aids, our formula doesn't knock you out artificially. It supports your body's natural transition into deep sleep. Most users report waking up feeling clearer and more alert — not foggy or sluggish. That's the difference between sedation and genuine recovery.

Yes. Cadence Sleep is Cologne List® approved, meaning every batch is tested for substances banned in sport. It's trusted by elite and professional athletes who can't risk contamination. You get effective sleep support without compromising your competitive status.
