The invisible environment that conditions health

The life expectancy in Spain has surpassed 84 years of age for the first time in 2025, according to data from the National Institute of Statistics (INE). A demographic milestone that reflects the country’s health and social advances, but life expectancy is not a general indicator of the level of health: living longer does not always mean living better. Therefore, the focus is no longer only on longevity, but on achieving a functional old age, with a higher quality of life, autonomy and well-being.

Traditionally, when we talk about health, we think about diet, physical exercise or genetics. However, there is growing scientific consensus that the environment weighs more than the genome in the development of many diseases: it is estimated that approximately 30% corresponds to the genetic load and around 70% to the exposomethat is, to the set of exposures that we accumulate throughout our lives.

This set of environmental and personal influences, which includes air quality, exposure to toxins, noise, inflammation or lack of deep sleep, is known as the Human Exposome and has become one of the great focuses of current scientific research. Some experts point out that its impact on long-term health may be even greater than that of the genetic load itself.

Sleep is one of the most decisive moments for the regeneration of the organism. During the deep phases of rest, the body activates essential processes of cell renewal and strengthening of the immune system. However, when sleep is disrupted by poor oxygenation, frequent awakenings, or a persistent inflammatory state, these mechanisms lose effectiveness and recovery ability is compromised.

In this context, recent preclinical studies indicate that adequate nocturnal oxygenation is associated with greater sleep efficiency, a reduction in oxidative stress and a more balanced cellular response. Therefore, the efforts in these investigations focus on analyzing how the rest environment can favor these processes in a passive and continuous way.

Within this line of work is Biowa technology that collaborates with scientific teams to study how certain environmental conditions can support cell regeneration during the night. The technology of Biow creates an optimized virtual exposomic microchamber in the room, generating a continuous laminar flow free of nanoparticles and enriched with bioavailable energy that reaches the body through respiration and the skin. In this way, it contributes to a healthier breathable exposomic environment, promoting general well-being, cellular energy, a more restful rest and strengthening the immune system.

Health, increasingly, depends not only on what we do during the day, but also on what the body is exposed to without being aware of it, especially while sleeping. An invisible factor that science is beginning to consider key to not only living longer, but living them better.
