Sleep disruption is one of the most underestimated costs of frequent travel.

 Whether you are an athlete, an executive, or someone whose role demands constant movement, the ability to rest properly when away from home is a decisive factor in performance.

The problem is that most people spend significant time designing an optimal sleep environment at home, yet abandon those principles the moment they step into a hotel.

The good news?

With some foresight and science-backed strategies, travel doesn't have to disrupt your sleep. The principle is simple: familiarity lowers threat response. By recreating the sensory cues and routines that signal “safe sleep” at home, you help the nervous system regulate, maintain circadian alignment, and achieve restorative rest even in unfamiliar settings [1,2].

Why Sleep Suffers During Travel

Sleep is foundational to cognitive performance, emotional regulation, immune function, and recovery [3]. But when we sleep in new environments, the brain often enters what researchers call the “first-night effect”, a state of lighter, fragmented rest designed to keep us alert to novel threats [4]. Add to that the disruptions of temperature, noise, light, diet, and routine, and you have the perfect recipe for poor recovery.

For frequent travellers, this isn’t just an inconvenience. It compounds into lowered performance, slower decision-making, impaired mood, and weaker resilience. Elite athletes and high performers are increasingly aware that winning margins can be lost in the bedroom, not just on the pitch or in the boardroom [5,6].

Strategies to Optimise Travel Sleep

Control the Room Environment
Temperature is one of the most influential variables in sleep quality. Research suggests 18–21°C is optimal, as it supports the body’s natural drop in core temperature needed for sleep onset [7]. Call ahead to request that your room be pre-set to your ideal range. Similarly, avoid rooms near lifts or busy streets, and if you are sensitive, consider a travel-sized HEPA purifier or white-noise device to stabilise air quality and sound [8].

Pillows and Bedding

Cervical alignment is critical. If the hotel offers a pillow menu, select the option that is closest to your home pillow in terms of loft and firmness. Many athletes go further and bring their own pillow or pillowcase on the road. Beyond comfort, this provides a familiar scent and texture, both of which help reduce novelty stress and encourage relaxation [9,10].

Familiar Scents and Sensory Anchors

Scent is a powerful regulator of emotional state. Using the same pillow spray at home and during travel conditions, the nervous system associates that smell with winding down [11]. Likewise, bringing your usual shower gel or moisturiser maintains consistency in pre-sleep rituals. These small cues carry weight; they tell the brain, “We are safe; it is time to sleep.”

Light and Darkness Control

Light is the most powerful regulator of circadian rhythms. Most hotels are inconsistent with their blackout provisions, so pack a high-quality eye mask. This creates both control of the dark phase and familiarity, reducing reliance on the room setup [12]. If mornings feel sluggish, a portable dawn-simulation light or set of light glasses can provide the same energising cue you rely on at home [13].

Routine and Rhythm

Your nervous system thrives on consistency. Keep your bedtime and wind-down sequence as close to home as possible: shower, reading, pillow spray, lights out. Avoid shifting caffeine or alcohol timing just because you are in a new environment, circadian rhythms depend on these anchors [14].

Noise Management

Unfamiliar noises are a common disruptor. Earplugs or noise-cancelling earbuds help, but many find white-noise apps or devices create a stable auditory environment that the brain quickly learns to tune out [15].

Nutrition and Hydration

Heavy evening meals compete with the sleep process, forcing the body to prioritise digestion over recovery [16]. Opt for lighter evening meals, taper fluids an hour before bed, and if crossing time zones, align meal timings with the local clock to accelerate circadian adjustment [17].

Psychological Framing

Accept that the first night may be lighter, that’s a natural response [18]. What matters is building strategies that minimise its impact: familiar smells, personal bedding, light and noise control. By reframing expectations and preparing, you prevent the spiral of stress that often worsens the problem.

From Science to Everyday Practice

These strategies are not only relevant to elite sport. Executives negotiating back-to-back time zones, hospitality staff working irregular hours, and even parents travelling with children face the same biological challenges. The difference is that most have not been taught how to control their environment.

The golden rule of travel sleep optimisation is replication. The closer you can get your hotel environment to mirror home, through temperature, scent, light, sound, touch, and routine, the faster your nervous system will downregulate, and the better you will recover.

The HMN24 system acts as part of that biological scaffolding that keeps you aligned, no matter where in the world you are.
