In a culture of constant notifications, late-night emails and cortisol-fuelled to-do lists, quality sleep has become one of modern life’s biggest wellness challenges.
For those of us who try to safeguard our wellbeing, sleep is often the one thing that remains elusive, but while a spa day can feel like an indulgence, a growing body of evidence suggests it may also be a powerful tool for better rest.
From nervous-system regulation to temperature-driven sleep cues, spa experiences align closely with how the body is designed to wind down. In this article we delve into why spa sleep benefits are more than just anecdotal, and how to make them last.
Stress is one of the most common sleep disruptors. When we’re under pressure, the body releases cortisol - the hormone that increases alertness and delays the production of hormones that signal to the body it’s time to sleep.
Sleep expert, Dr Maja Schaedel, who oversees Ockenden Manor's Good Sleep Retreat, says: "One of the main things that keeps people awake is an overactive state of hyperarousal, which is really the result of the flight/fright freeze response - otherwise known as the autonomic nervous system. All those reactions are the opposite of what you need to sleep - you can't sleep if you think you're in danger - the body will naturally fight to keep you awake."
Research shows that relaxation practices which activate the parasympathetic nervous system significantly reduce cortisol levels and improve sleep onset and depth. Spa environments can be a helpful way to help the mind and body unwind, and influence that shift.
Dr. Nerina Ramlakhan, a physiologist and sleep therapist, has been quoted as saying: "Our health, our wellbeing, our quality of life depends on where we are living in the nervous system."
We know anecdotally, as well as through a fairly disparate approach to research, that spa experiences can be a powerful contributor to overall wellbeing.
Sleep is closely linked to body temperature. As evening approaches, core body temperature naturally drops, signalling the brain to prepare for rest. Thermal spa therapies work with this mechanism, which is why lots of us sleep well after sauna experiences, or time in thermal suites spanning different temperatures.
Studies show that passive body heating - even something as simple as a hot shower or bath is "associated with both improved self-rated sleep quality and sleep efficiency." For those who want to extend that ritual, sauna bathing in the late afternoon or early evening may help enhance that effect, and in many instances people report getting to sleep faster and having a better night’s rest than they normally do.
Hydrotherapy pools, steam rooms and thermal circuits create a similar effect, with contrast experiences (alternating warm water with brief cold exposure) further supporting circulation and relaxation. While cold plunges are often associated with energy and alertness, emerging evidence suggests short, controlled exposure earlier in the day may reduce inflammation and improve nighttime recovery.
In broad terms, the most sleep-supportive spa therapies are the ones that encourage both physical relaxation and mental calm. That seems obvious, but when it comes to choosing what treatments to have when, it’s worth remembering that some are more geared towards energising than inducing sleep. It’s always worthwhile talking to your therapist before your treatment to make sure they know what your goals are, and how you want to feel at the end of your spa time.
Research shows what many of us know instinctively - that massage increases serotonin and dopamine while reducing cortisol, all of which is associated with improved sleep and reduced nighttime disturbance. If sleep is the goal, we suggest choosing a massage that’s designed for rest and relaxation, like an aromatherapy massage instead of one that’s more geared towards sports recovery, for example.
Warm water immersion reduces muscle tension, eases joint discomfort and promotes restful sleep. This is particularly beneficial for people whose sleep is disrupted by physical stress or pain.
Regular sauna use has been associated with improved sleep efficiency and reduced symptoms of insomnia, especially in people experiencing work-related stress.
While individual therapies and experiences have their own benefits, when they are brought together as part of a spa day, you have time to get maximum benefit from them all, relaxing the mind and body, and, hopefully, supporting all aspects of sleep: quicker sleep onset, longer deep-sleep phases, and fewer awakenings.
A spa day is a wonderful way to help the body reset, whether you take time once a month, once a quarter, or once in a while. However, they’re also wonderful ways to get inspiration for little rituals you can bring into your home routine to support better sleep consistently. For example, you can try:
Sleep is not just about hours in bed; it’s about how effectively the body transitions from alertness to rest. Spa experiences combine temperature regulation, touch therapies, sensory calm and mental cues that help you to switch off, which is something many of us struggle to create space for at home. After all, sometimes the best way to sleep better is to truly relax first.
