What the research shows about indoor climate, humidity and sea air
An honest, source-based overview of the scientific background behind SalinoVatis — on indoor humidity and on well-being by the sea. With linked, peer-reviewed studies, and deliberately without any promises of healing.

Dry indoor air, the airways and the ideal humidity level
Significantly dry air can contribute to eye and respiratory discomfort and reduce the self-cleaning of the mucous membranes. A relative humidity of around 40–60 % is favourable. (Int. Journal of Hygiene and Environmental Health, 2023)

How humidity affects the mucous membranes and their protective function
Humidity influences the properties of mucus and the self-cleaning of the airways. An intact mucus layer protects the mucous membranes from irritants. (Int. Journal of Molecular Sciences, 2023)

Why living spaces are often too dry in winter
A large analysis of Sweden's building stock shows that during the heating season, humidity in homes is often too low — and is associated with more frequent complaints. (Building and Environment, 2021)

Office air in practice: higher humidity, less feeling of dryness
Across 43 office buildings, higher humidity levels were associated with less dryness of the throat and skin and with less frequent tiredness. (Indoor Air, 2021)

Humidity and the airways: findings from a large population study
A population study with over 10,000 participants confirms a measurable link between humidity and respiratory symptoms — a balanced range matters. (Respiratory Research, 2024)

Sea, coast and well-being
Many people associate the sea with calm and recovery. These studies show how spending time by the coast and water relates to well-being — the feeling SalinoVatis aims to bring into the home.

Living by the coast: higher well-being across 18 countries
A survey across 18 countries found that people living near the coast more often report high well-being, and time spent by the water is associated with less strain. (Scientific Reports, 2021)
