Your appliances ground through that socket. Your nervous system needs the same.

The Earth carries a natural negative electrical charge, a vast reservoir of free electrons. When your body makes conductive contact, these electrons transfer in and neutralise positively charged free radicals that drive inflammation, oxidative stress, and tissue damage.

For most of human history, humans slept on the ground and absorbed this supply naturally. Modern life broke that circuit: rubber soles, synthetic floors, raised beds. Cadian restores it. Same grounding principle as your power socket's earth pin, delivered through conductive silver woven into your sheet.

Most sleep advice ignores the biggest problem.

You track your sleep. You see the data. Light sleep dominates. Deep sleep is fragmented. You wake up tired. Without earth contact, your nervous system stays in sympathetic overdrive all night.

Grounding during sleep reduces cortisol and resynchronises its secretion with your natural circadian rhythm (Ghaly & Teplitz, 2004). A 2025 RCT confirmed significant reductions in insomnia severity and daytime sleepiness (Park et al.).

Earthing in Lifestyle Medicine

All 20 studies reported significant physiological improvements. 'Clearly deserves inclusion in clinical practice.' Menigoz et al.

KEY STUDY 5/5 2015

Inflammation & Immune Response

Grounding reduces or prevents all five cardinal signs of inflammation. Measurable changes in white blood cells and cytokines. Oschman et al.

Earthing is a simple, natural, and yet profoundly effective environmental strategy against chronic stress, ANS dysfunction, inflammation, pain, poor sleep, disturbed heart rate variability, hypercoagulable blood, and many common health disorders, including cardiovascular disease.

COMPREHENSIVE BENEFITS

One Sheet. Five Body Systems. Every Base Covered.

Most people try to fix sleep with one supplement or one device. Cadian works across your entire nervous system while you sleep.

Nervous System
Grounding shifts your autonomic nervous system from sympathetic (fight or flight) to parasympathetic (rest and recover) dominance. This is measurable via heart rate variability. A 2024 review confirmed grounding consistently produces this shift, associated with reduced anxiety, improved stress resilience, and better emotional regulation.
Supported by: Medical Research Archives 2024, Menigoz et al. 2020
Inflammation
Grounding reduces or prevents the cardinal signs of inflammation: redness, heat, swelling, pain, and loss of function. Free electrons from the Earth neutralise positively charged free radicals, the same mechanism as antioxidants but delivered directly through skin contact. Medical infrared imaging confirmed rapid resolution of chronic inflammation across 20 case studies.
Supported by: Oschman et al. 2015 (Journal of Inflammation Research)
Cortisol
Grounding during sleep reduces night-time cortisol levels and resynchronises cortisol secretion with your natural 24-hour circadian rhythm. A 2025 randomised, double-blind, placebo-controlled trial confirmed grounding mats significantly reduced stress, insomnia severity, and daytime sleepiness compared to placebo.
Supported by: Ghaly & Teplitz 2004, Park et al. 2025 (RCT)
Circulation
Grounding increases the electrical charge on red blood cells (zeta potential), reducing clumping and blood viscosity. Less viscosity means better oxygen delivery, lower cardiovascular strain, and improved nutrient transport. One hour of grounding produced measurable improvements in blood flow visible on thermal imaging.
Supported by: Chevalier et al. 2013, Chevalier et al. 2015
Recovery
Grounded subjects showed reduced pain, faster recovery, and altered levels of circulating neutrophils and lymphocytes consistent with a modulated inflammatory response after exercise. A 2019 randomised controlled trial on massage therapists confirmed consistent benefits in pain reduction, physical function, and mood improvement.

REAL PEOPLE. REAL RESULTS.

What Cadian users are saying. Verified results.

Sleep
Deep sleep up in the first week.
I was part of the early group that got access before launch. Tracked everything on Oura. Deep sleep measurably up by night four. Was not expecting results that fast.
Marcus T.
Sleep
Sleeping through for the first time in years.
Got early access through a friend. I was sceptical. Two weeks in and I am sleeping through the night consistently. That has not happened in a long time.
Sophie L.
Sleep
HRV improvement I cannot explain away.
Early tester here. I track obsessively on Whoop. HRV baseline shifted up in week two. I have not changed anything else so the sheet is the variable.
Nina S.
Recovery
Recovery window noticeably shorter.
Was invited to test this before it went public. I train five days a week. Soreness is resolving faster. Not dramatically, but consistently. Enough to notice.
Tom B.
Recovery
Coach asked what I had changed.
Early access tester. My coach flagged improvement in my recovery metrics before I mentioned the sheet. That told me more than any self-reported feeling could.
Emma P.
Recovery
Resting heart rate down after two weeks.
Got the sheet as part of the pre-launch group. RHR dropped 3bpm over two weeks on Garmin. Small but consistent. Everything else in my routine stayed the same.
Luke R.
Inflammation
GP noted change in bloodwork at six weeks.
I was an early user before public launch. My GP flagged improvement in inflammation markers at my six-week check. I had not told her about the sheet before she mentioned it.
David M.
Inflammation
Joint discomfort more manageable.
Early tester with chronic lower back inflammation. Not a cure but the reduction over six weeks has been real. Sleep quality improved alongside it which compounded the effect.
Rachel W.
Inflammation
Something shifted in week three.
Part of the early access group. Hard to quantify inflammation subjectively but week three something changed. Less morning stiffness. Sleep scores improved the same week.
Sarah K.
Performance
Recovery scores consistently in the green.
Early tester, Whoop user for three years. Best sustained recovery streak I have had started the week I put this sheet on. The correlation in the data is hard to ignore.
James C.
Performance
Every metric moved in the right direction.
Got early access before launch. Deep sleep up, RHR down, HRV baseline higher. Not every night is perfect but the trend line across four weeks is clear.
Sandor K.
Performance
Output in training improved noticeably.
Early user, competitive CrossFit. Performance in training lifted in week three. Felt more recovered going into sessions. Coach confirmed the output data matched how I described feeling.
Jess K.

FAQ

Common questions. Answered.

The Earth carries a natural negative electrical charge. Cadian sheets are woven with conductive silver thread that connects to the earth pin of any standard AU/NZ power outlet via a grounding cord. No electricity flows through the sheet. Free electrons transfer through your skin while you sleep, neutralising free radicals that drive inflammation and disrupt recovery.
Yes. 15 peer-reviewed studies support grounding for sleep, inflammation, and recovery. The 2025 Park et al. study is a randomised, double-blind, placebo-controlled trial confirming grounding reduces insomnia, stress, and daytime sleepiness. A 2020 review of 20+ studies concluded grounding clearly deserves inclusion in clinical practice.
Completely. The grounding cord connects only to the earth pin of your outlet. No electrical current flows through the sheet. Materials are OEKO-TEX certified and the conductive silver is woven directly into organic cotton.
Most users with sleep trackers report measurable changes in deep sleep and HRV within 7 to 14 nights. Some notice improvements within the first few nights. The 2004 Ghaly and Teplitz study measured cortisol changes over an 8-week period.
We offer a 100-night data guarantee. Track your sleep and if it doesn't improve, get a full refund. No return required.
Machine wash cold, gentle cycle. No bleach, no fabric softener. Tumble dry low or hang dry. The sheet is rated for 500+ wash cycles with no loss of conductivity.
Yes. The sheet sits on top of your fitted sheet on any mattress type. It works with innerspring, memory foam, latex, and hybrid mattresses.
Skin contact improves conductivity, but the sheet works through thin clothing too. Most people place it where their torso contacts the bed.
