There\u2019s a saying we all know: \u201cApril, sweet sleep.\u201d<\/em> As the days grow longer and temperatures become milder, sleep seems to come more easily. But today we know that simply sleeping is not enough\u2014we need to sleep well. And to do so, the environment in which we rest plays a fundamental role.<\/p>\n

An increasing number of studies show that indoor air quality directly affects sleep quality<\/a>. During the night, air quality tends to worsen simply because we spend many hours in a confined space without proper air circulation. Most people sleep with doors and windows closed, leading to a buildup of pollutants and CO\u2082 in the room.<\/p>\n

When the air in the bedroom becomes \u201cstale,\u201d micro-awakenings can occur, interrupting or fragmenting REM sleep phases and reducing overall sleep quality.<\/p>\n

So, what is the recipe for restorative sleep?
\nTo sleep well, it is essential to create a precise balance between several factors: CO\u2082, temperature, and humidity.<\/p>\n

CO\u2082: the invisible enemy of sleep<\/h4>\n

During the night, as we breathe, we consume oxygen and produce CO\u2082. In a closed or poorly ventilated room, levels can easily exceed 1000 ppm, a threshold beyond which air quality begins to deteriorate.<\/p>\n

1000 ppm (parts per million) of CO\u2082 means that out of 1,000,000 air molecules, 1000 are carbon dioxide (approximately 0.1% CO\u2082 in the air). Optimal levels for well-ventilated indoor environments should range between 600\u2013800 ppm. Above 1000 ppm, the air starts to feel stale and less healthy.<\/p>\n

High CO\u2082 levels in bedrooms are associated with lighter, less restorative sleep. Some studies also point to poorer cognitive performance the following day.<\/p>\n

Temperature and humidity: the right balance makes the difference<\/h4>\n

The ideal temperature for sleep generally ranges between 18\u00b0C and 20\u00b0C. Higher values can disrupt REM sleep, while temperatures that are too low may cause awakenings.<\/p>\n

Humidity is also a key factor: in winter, if the heating system stays on for too long during the night, the air becomes dry and can irritate the respiratory tract. On the other hand, excessively high humidity can cause discomfort, sweating, breathing difficulties, and over time promote the formation of mold and dust mites.<\/p>\n

Ideally, humidity should be maintained between 40% and 60% to ensure optimal comfort and health benefits.<\/p>\n

Why opening windows is not the solution<\/h4>\n

One might think that opening windows is the easiest and quickest way to get fresh air\u2014but in reality, it\u2019s not that simple. There are several drawbacks:<\/p>\n
