Air travel exposes the human body to an environment unlike anything encountered on the ground. Cabins are engineered for safety and relative comfort, but the physiological stressors of altitude, including reduced oxygen availability, altered hormonal signalling, and extremely low humidity, create a perfect storm for dehydration. While jet lag and circadian disruption are often the focus of discussion, the physiological impact of altitude on hydration is a distinct challenge in its own right and demands targeted management.

Discover the science behind sleep temperature and mattress selection. Learn how airflow, materials, and new technologies influence thermoregulation, deep sleep, and recovery.

With British Airways recently announcing that it is listing a hydration solution as part of its short-haul offering, this signals a growing shift in how the travel industry is addressing the physiological challenges of flying.

Most people think poor sleep comes from the glass of wine they had before bed.

But the truth is, that glass is usually just the final act in a much longer story, one that started the moment your alarm went off.

HMN24 isn’t just a supplement brand. It’s a neuroscience-led system designed around three core principles: Circadian Modulation, Jet Lag Mitigation, and Arousal State Management. We’ve developed protocols trusted by elite athletes, special operations units, and high-performance travellers, and we’re now embedding them into the world’s leading hospitality environments.

Modern neuroscience confirms what ancient traditions have practised for millennia: the first few minutes after you wake up are biologically powerful.

Your brain doesn’t flick on like a light switch. It transitions, slowly and delicately, through a cascade of brainwave states.

The hospitality industry is in the midst of a significant evolution. Wellness is no longer a niche feature or optional add-on. It is becoming a central pillar of the guest experience.

Fasting is not simply a wellness trend; it is a deeply conserved biological behaviour observed across mammalian species. Feeding and fasting cycles in mammals are governed by circadian rhythms, the internal timekeeping systems that align physiological functions with the 24-hour light-dark cycle.

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:

The interplay between core body temperature, bedding, ambient environment, and emerging thermoregulation technology represents a foundational pillar of sleep health. By understanding and manipulating these variables, through smart material choices, proper environmental control, and tech-assisted precision, individuals can improve sleep onset, reduce fragmentation, and enhance the overall restorative value of sleep.

In health, as in early development, rhythm is not optional. It is foundational. From light exposure to nutrient timing, from wake cycles to sleep architecture, every major system in the body is governed by time, and when we ignore that clock, performance, mood, recovery, and resilience all suffer.

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.
