We spend roughly a third of our lives asleep. And yet, with ever-longer days and the commitments and habits that keep us constantly on the go, sleep is often one of the first things we borrow time from.
Sleep is not simply a pause in the day. While we sleep, the body keeps working: it recovers energy, consolidates what we have learned and our memories, is involved in regulating metabolism and plays a part in the activity of the immune system. Even changes in how long and how well we rest can have consequences for our physical and mental wellbeing. Sleeping well, then, is not a luxury. It is an essential part of our wellbeing.
How long we sleep is not all that counts
Thinking about the quality of sleep purely in terms of hours is too narrow a view. Over the course of the night we pass through several stages, each with its own characteristics.
NREM sleep moves from drifting off, through light sleep, to deep sleep – which is particularly important for recovering from the tiredness and sleepiness built up during the day. These stages alternate with REM sleep, which is more present in the second half of the night and is characterised, among other things, by more vivid dreaming.
These stages follow one another in cycles: the first episode of REM sleep normally appears around 90 minutes after falling asleep, before giving way once more to NREM sleep. How unbroken our rest is therefore matters as much as how long it lasts.
Sleep keeps a precise rhythm
The body has a genuine internal clock: the circadian rhythm. Over the course of 24 hours it regulates the sleep–wake cycle and many other physiological processes, from body temperature to the production of hormones. One of its main regulators is natural light.
As light fades, the body gradually prepares for rest; when light increases again, the body receives a signal to become active once more. This is partly why soft, warm light in the evening can help us fall asleep, while exposure to natural light in the morning helps to synchronise our body clock.
Sleep, then, does not simply begin the moment we get into bed. It is the result of a balance we build over the whole day.
The room we sleep in is part of that balance too
Personal habits and rhythms are fundamental, but our surroundings can also either support rest or stand in its way.
A dark, quiet bedroom at a comfortable temperature creates conditions better suited to sleep. In the same way, the mattress and pillow should allow the body to find and hold a comfortable position through the night. The guidance gathered by Fondazione Humanitas Ricerca highlights precisely the importance of bedroom conditions and of a suitable sleep system. And this, perhaps, is where the way we look at the bedroom changes. Not simply as a room to be furnished, but as the space we devote, every day, to the body’s recovery.
Investing in sleep means investing in your wellbeing
We are used to paying attention to what we eat, to exercise, to posture or to the quality of the spaces in which we spend our days. Sleep deserves the same consideration.
This does not mean searching for the “best” mattress in absolute terms. Rest is personal: build, sleeping position, the way we perceive support, habits and needs all differ. That is precisely why the quality of a bed system cannot be judged from a specification sheet or a price alone.
Mattress, base, pillow and the conditions of the room work together, and they accompany the body for thousands of hours every year. Choosing them carefully means investing in something we use every night, and which plays a direct part in the quality of our rest.
Because, in the end, a good bed system is not simply there for sleeping. It has to create the conditions for sleeping well.
