You don’t sleep on a mattress,  you sleep inside three thermal microclimates that sit between your body, your clothing and your bedding. These microclimates determine how quickly you fall asleep, how deeply you stay asleep and how well you recover. This piece explains the science, the technologies that improve it, and how to optimise your environment even without tech.

Scent is one of the fastest ways the environment communicates with the nervous system. Some aromas cue safety and calm, while others quietly elevate stress. This article breaks down the science behind scent, why familiarity matters, which aromas soothe versus stimulate, and how to design scent environments for performance, sleep, and recovery.

Modern wellness often focuses on what happens inside the body, diet, sleep, and exercise,  while ignoring the world around it.

This article explores why environmental literacy, understanding how air, light, temperature, sound, and spatial design shape physiology—is emerging as the missing skillset in wellness and performance. It argues that to truly optimise humans, we must first optimise the environments they inhabit.

The First-Night Effect is a neurobiological safeguard that keeps one half of your brain more alert in unfamiliar environments. While adaptive, it disrupts recovery. This article explores the science and practical ways to minimise its impact.

Frequent travel doesn’t have to derail your sleep. By replicating familiar cues, temperature, scent, light, and routine—you can trick the nervous system into perceiving safety and calm, even in a hotel room. Our latest article explores the science behind travel sleep optimisation and offers practical steps for high performers to protect recovery on the move.

Jet lag is often seen as a sleep problem. But hydration and electrolyte balance play a fundamental role in circadian alignment, recovery, and adaptation to new time zones. This article explores the science and shares practical hydration protocols for travel.

Sleep tourism is transforming how we travel. No longer about indulgence or adventure alone, the new luxury is restoration. This article explores the science, industry shifts, and practical applications behind the rise of sleep-focused travel, and what it means for performance, hospitality, and everyday wellbeing.

Social jet lag is the hidden disruptor of modern life. Mimicking the effects of travel across time zones, it erodes energy, focus, and recovery week after week. This post explains the science behind social jet lag, why it matters for health and performance, and how simple circadian strategies can help realign your body clock.

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.

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.

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.
