Circadian rhythms are more than sleep–wake cycles, they are the foundation of human performance. From morning focus to evening recovery, your body runs on rhythm. This post explores the science behind circadian alignment, the costs of disruption, and how high performers and organisations are using rhythm to unlock clarity, resilience, and recovery.

Optimising dopaminergic tone without succumbing to burnout is one of the pivotal challenges in contemporary performance and wellness. In today’s culture of quick fixes, excessive caffeine consumption, overstimulating activities, and “always on” behaviours often dominate strategies for focus and motivation.

In today’s world of supplements and biohacks, complexity is king.

We’re offered DNA tests to guide our diets, microbiome kits to interpret our gut, and 50-ingredient blends to "cover all bases."

But amidst the noise, we've lost sight of one of the most foundational elements of human health:

Scientific consensus began to shift. Sugar wasn’t just energy, it became a metabolic risk. Excess glucose intake was now linked to obesity, Type 2 diabetes, systemic inflammation, and chronic disease.

One of the key ingredients in HMN24 Flow is Lion’s Mane (Hericium erinaceus), an emerging natural compound gaining increasing attention in scientific research. While still in the early stages of validation, preliminary studies and traditional use suggest promising benefits, particularly in cognitive function and nervous system health.

Caffeine and theanine are compounds found in tea but have very different effects on our brains. Caffeine is a well-known stimulant that increases alertness and reduces fatigue, while theanine is an amino acid that promotes relaxation without sedation.

In a recent Podcast, HMN24 Co-Founder Phil Learney was asked about the implications of sleep-wake disruption on professional footballers and what an adjusted schedule may look like and how HMN24 products would be integrated into it. 

Remember that your ‘need’ for caffeine, a stimulant, is mainly driven by your ‘need’ for sleep.

Also, your ‘need’ to use a depressant such as alcohol before bed is often driven by the overuse of the aforementioned stimulant.
