Does pollution affect sleep ?

We sleep for almost a third of our lives, just over 23 years. Sleep is one of the foundations of our health, our well-being and therefore our quality of life. We all know that air pollution is dangerous for our health. It increases the risk of cardiovascular and respiratory diseases such as asthma.

It is therefore only natural to protect ourselves from air pollution during our long rest periods! But did you know that air pollution can also disturb your sleep?

Air pollution influences sleep

A study conducted by Antonella Zanobetti, a doctoral student in public health at Harvard School, confirms the effect of air pollution on sleep, particularly in people with sleep apnea.

Aggravated symptoms for people with apnea

Sleep apnoea is characterised by interruptions in breathing during the night. The sleep cycle is severely disrupted, leading to daytime sleepiness, high blood pressure and heart disease. Sleep apnoea syndrome affects nearly 2 million people in France, particularly men (60%) between 55 and 70 years old. (Source: Vitalaire)

This study found that the presence of particulate matter in indoor air increases breathing problems during sleep. The risk of respiratory arrest in people with sleep apnea increases by 13% during the summer. The temperature is higher and pollution intensifies during this period.

In practical terms, what are the risks?

Concretely, the deep breathing that occurs during sleep causes the body to inhale many particles. These pollutant particles affect the nervous and respiratory systems, leading to coughing, sneezing, inflammation These pollutant particles affect the nervous and respiratory systems, causing coughing, sneezing, sinus inflammation, headaches and tiredness in the morning.

Thus, people with breathing difficulties, asthma or allergy sleep poorly due to poor air quality which aggravates their symptoms.

The higher the pollution, the less recuperative the sleep as the increase in sleep apnea episodes and breathing problems reduces the duration of recuperative sleep phases.

Air quality also affects the quality of sleep of people who do not have such problems.

Another recent Danish study shows that sleep is better in a well-ventilated room. This study measured the concentration of CO2 and is an interesting clue to the role of pollutants on how fresh we feel in the morning. Discover now our air purifiers that will improve the quality of your sleep.
