The science
Deep sleep and testosterone are directly linked.
Your body makes most of its testosterone at night, in deep sleep. The better you sleep, the more you make.
- Most of it is made while you sleep.Testosterone climbs from the moment you fall asleep and peaks around three hours in.
- Bad sleep cuts it by 10–15% in a week.In a University of Chicago study, young men who slept five hours a night for a week saw their daytime testosterone drop by 10–15%. That's like ageing 10 years.
- Good sleep brings it back.When the men went back to sleeping normally, their levels recovered.
So here are four ways to sleep deeper, starting tonight.
Hack 1 · Consistent Sleep Hours
Go to bed and wake up at the same time, even at weekends.
Your body clock decides when testosterone is made. Keep it steady and you hit deep sleep at the right moments.
- Same bedtime, same wake-up.Within 30 minutes either side, seven days a week.
- No big lie-ins.A two-hour weekend lie-in shifts your body clock like a short flight.
- A dark, cool room.Around 18°C, curtains shut, phone out of reach.
Costs nothing. Starts tonight.
Hack 2 · Ultra Blue Blocking Glasses
Block the screen light that keeps you out of deep sleep.
Put them on 1–2 hours before bed. They filter out 99%+ of blue and green light, so your brain gets the signal to wind down and you reach deep sleep sooner.
- Filters 99%+ of blue and green light.The wavelengths (roughly 400–550nm) that hold back melatonin, your sleep hormone.
- Carry on as normal.Scroll, work, watch TV. The frames fit over prescription glasses.
- About 30 minutes more sleep.In a Columbia University study, people with insomnia who wore amber lenses for two hours before bed slept about half an hour longer a night.
Included in the bundle.
Hack 3 · Deep Sleep Earplugs
Block the noise that pulls you out of deep sleep.
Put them in at lights out. Traffic, snoring and early-morning noise fade into the background, so the hours that matter for testosterone aren't broken up.
- Cuts noise by 23 decibels.Rated SNR 23 and tested to EN 352-2, the European standard for earplugs.
- Soft silicone, four sizes.XS to L tips, so they sit comfortably even if you sleep on your side.
- One reusable pair, with a carry case.For home, hotels and flights.
Included in the bundle.
Hack 4 · Sleep & Recovery
Calm the stress that cuts your deep sleep short.
Two capsules, 30–45 minutes before bed. Six natural ingredients that work on the conditions your testosterone needs. No melatonin, no sedatives.
- L-theanine.Lowers late-night cortisol, so the hormonal window stays open.
- Magnesium bisglycinate.Supports testosterone production. Most men don't get enough.
- Apigenin.Helps you stay longer in the deep sleep stages, where the real work happens.
The heart of the bundle.
The science
“The evidence is unequivocal: sleep quality is directly linked to testosterone production. The worrying thing for men is that most don't know they aren't getting the right quality of sleep. This means they're missing out on key testosterone production during the night.”
Dr Tom GurneyChief Science Officer
What you get back
More deep sleep. More energy, drive and focus.
Most testosterone decline is a sleep problem wearing a hormone mask.
- More drive, more energy.Wake up ready, not running on caffeine.
- Better recovery.Deep sleep is where your body repairs and rebuilds after training.
- A steadier mood.Lower cortisol at night means a calmer, sharper you by day.
The way your body is supposed to work.
