By the time we are 75 years old, we will have slept for 25 years, i.e. one third of our life. Sleep plays an important role in our health, our well-being and therefore our quality of life. Perhaps you are one of those who have trouble sleeping? Pollution could contribute to your insomnia.
Sleep apneaaffects nearly 2 million French people and mainly affects men between 55 and 70 years old. It is characterised by slight interruptions in breathing during the night. People with apnea have a higher risk of developing a higher risk of developing high blood pressure and cardiovascular disease.
A study conducted by Antonella Zanobetti, a doctoral student in public health at Harvard School, highlights the harmful effects of pollutants on the sleep of people with apnea. The study was conducted in 7 American cities Phoenix, Arizona; Tucson, Arizona; Sacramento, California; Firmingham, Massachusetts; Minneapolis, Minnesota; New York City, New York; Pittsburgh, Pennsylvania. The result is clear: the more concentrated the polluting particles are, the less recuperative the sleep and the more apnea. With the sun and the heat of the summer, which is conducive to pollution, the risk of respiratory arrest is even greater: it increases by 13% in apneics.
A recent US study, conducted by researchers at the University of Washington, shows that the higher the exposure to nitrogen dioxide and fine particles (PM2.5), the lower the quality of sleep. The study, presented at the the 2017 American Thoracic Society International Conference, involved more than 1,800 Americans over a five-year period. The data collected allowed the researchers to measure the participants' sleep quality, which which is the ratio of time spent sleeping to time spent in bed. The results? Participants exposed to the highest levels of NO2 and PM2.5 had a 50% and 60% increased risk of poor sleep quality respectively. They also had more difficulty falling asleep. Inhaled particles affect the nervous and respiratory systems, causing coughing, sneezing, sinus inflammation, headache and tiredness in the morning. For people with breathing difficulties, asthma or allergies, their symptoms become more intense.
