Are You Tired Of Being Tired?
And The Generic Sleep Advice Isn't Working?
You're Exhausted Despite Trying Everything
- You wake up tired, no matter how many hours you slept
- You hit a wall in the afternoon and rely on caffeine
- Your body feels under-recovered and your mind feels foggy
Your Sleep Data Doesn't Make Sense
- Your wearable says you slept fine, but you feel terrible
- Travel, stress, and work demands constantly derail your routine
- You've tried generic tips but nothing sticks long-term
You're Ready To Take Control
- You want a system built for your biology, not generic advice
- You value expert guidance and data-driven decisions
- You are ready to invest in your energy, focus, and performance
If this sounds like you, and you're ready to take action, The Circadian Advantage was built for you.
You Don’t Need More
Generic Sleep Advice
Most people are told to improve their sleep with the same basic advice. But if you are a high performer and still waking up tired, crashing in the afternoon, or struggling to recover properly, the real issue is often much deeper.
What most sleep advice tells you
This is the standard advice most people hear:
- Go to bed earlier
- Avoid caffeine
- Turn off your phone
- Try a supplement
- Follow a basic sleep hygiene routine
What may really be affecting your sleep
For high performers, the root cause is often a combination of deeper biological and lifestyle factors:
- Circadian rhythm disruption
- High stress load
- Nervous system dysregulation
- Poor light exposure habits
- Training or exercise timing
- Nutrition and meal timing
- Work demands and mental load
- Travel and changing schedules
- Bedroom environment
- Recovery habits
- Genetics and internal health markers
A Truly Tailored Sleep Performance Programme
The Circadian Advantage is not a generic sleep plan.
It is a personalised coaching programme built around your body, your data, your lifestyle, and your performance goals.
We combine:
This is for people who want more than basic sleep advice.

Client Transformations
These are real examples of what can happen when sleep is no longer treated as a generic checklist, but as a personalised performance system.

Your Sleep Data Should Make Sense
Many high performers use Oura, Apple Watch, Garmin, WHOOP, or other wearables to track their sleep and recovery. The problem is that most people do not know what to do with the data. Even worse, the data often does not match how they feel.
The Circadian Advantage helps you connect the dots between:
You do not need more data. You need better interpretation, better decisions, and a better system.
The CORE Method
A complete system for sleep, energy, recovery, and performance. The Circadian Advantage is built around four key pillars.
C — Circadian Timing
We optimise the timing signals that control your internal body clock.
- Morning and evening light exposure
- Sleep and wake timing
- Meal timing
- Hydration timing
- Exercise timing
- Temperature regulation
- Travel and jet lag protocols
O — Output
We optimise how you perform during the day without burning out your system.
- Energy management
- Cognitive performance windows
- Stress load management
- Workday structure
- Training readiness
- Afternoon crash prevention
- Evening down-regulation
R — Recovery
We optimise the systems that help your body fall asleep, stay asleep, and recover deeply.
- Sleep pressure
- Nervous system recovery
- Deep sleep and REM optimisation
- HRV and resting heart rate trends
- Hormonal rhythm support
- Recovery from stress, training, and travel
E — Environment
We optimise your surroundings so your biology is not fighting your lifestyle.
- Bedroom temperature
- Light exposure
- Noise
- Air quality
- Work environment
- Evening stimulation
- Travel environments
How Coaching Works
Assess. Align. Act. Adapt.
The Circadian Advantage uses a simple but powerful coaching framework to turn complex data into clear action.
1 Deep Dive Assessment
We start by mapping your current sleep, recovery, and performance baseline. Depending on your coaching programme, this may include:
- Lifestyle and routine assessment
- Sleep and performance questionnaire
- Wearable sleep data review
- Oura, Apple Watch, Garmin, or WHOOP analysis
- HRV, resting heart rate, readiness, and recovery trends
- Genetic insights
- Bloodwork review
- Stress, travel, training, and work demands
The goal is simple: Find the real reasons your sleep, energy, or recovery is not where it should be.
2 Align Circadian Biology
We turn your data into a personalised sleep performance blueprint. You will understand:
- What is currently holding you back
- What matters most for your body
- Which habits to prioritise first
- Which sleep metrics to focus on
- Which data to ignore
- How to build a realistic routine that works with your life
No overwhelm. No random hacks. Just the highest-leverage actions for your biology.
3 Action and Execution
You implement the plan with expert coaching support. This may include:
- 1:1 coaching calls
- Daily support by WhatsApp or email
- Personalised action steps
- Weekly adjustments
- Accountability
- Sleep, light, nutrition, exercise, recovery, travel, and supplement protocols
You are not left alone with a report. You get coaching, feedback, and course correction as your life changes.
4 Adapt and Optimize
Your protocol evolves based on real results. We track what is improving, what is not working, and what needs adjusting. This may include:
- Sleep efficiency
- Deep sleep and REM trends
- HRV
- Resting heart rate
- Energy

Best thing I ever did was doing the sleep challenge 🙏🏻
"As a single working mum of 2 & the extra stress of trying to cope with a new online business... My sleep was all over the place & I felt like I was close to burning out. The sleep challenge course was the best thing I did as it educated me & opened my eyes to things I was doing throughout the day that were affecting my sleep. Angus has a really calm & great way of explaining things & his knowledge is out of this world."

"I worked with Angus for 3 months and the experience was outstanding both in terms of results as well as the support and delivery of the service. Before starting I had significant inconsistency when it comes to sleep timing and length as well as relying on caffeine to get me through most of the day. After working with Angus I saw instant results within the first 2-3 weeks and then slowly optimized everything by the end of the 3 months. I highly recommend working with Angus for anyone who takes their health and performance seriously"

"Working with Angus has truly been a life changing experience. After years of insomnia and being on the verge of burnout, I knew I had to address my sleep. Within just 4 days of working with Angus - I had the best sleep in 20 years and I immediately signed up for more. Angus is truly a world class coach. He has a wealth of knowledge and genuinely cares about helping you achieve your peak. I feel like a new person, my friends say they have 'the old me' back, and it's really transformed my experience of life and performance in business. Forever grateful to you Angus!"

"Angus and the Sleep Performance Coach cert gave me an extremely valuable tool in the coaching toolbox. It helped transform how a lot of my coaching clients recovered and how seriously they started treating their recovery. The fact Angus also not only teaches, but shares his resources with you speaks volumes about how passionate he is about sleep. I'd recommend the Sleep Performance Cert in a heartbeat."

"I highly recommend Angus as a sleep and health performance coach. I suffered with insomnia for 10 years. I tried many different professional services and none of them were effective. After working closely with Angus, he was able to help resolve my insomnia within 8 weeks. Angus genuinely cares about making improvements, ensuring you are on track and giving advice that is sustainable and fits within your life style. After working closely with Angus, it is evident that he has a wealth of knowledgeable and experience within this field."
