“Sporty” women reported sleeping better and having less sleep problems, including during the day.

A team of researchers at the University of Alabama in Birmingham, USA, investigated the effects of regular physical activity on the sleep quality of 222 breast cancer survivors after treatment.

After cancer, sports can fight against fatigue and cognitive failures, two symptoms commonly encountered after the disease, have shown previous studies.

For the purposes of this new work, the participants were included in a protocol called “BEAT Cancer” (Better Exercise Adherence after Treatment for Cancer), consisting of aerobic training exercises in the broad sense for three months. A control group also received the usual care, says the study.

According to the results measured after three months thanks to the Pittsburgh Sleep Quality Index (PSQI), a scale that evaluates sleep patterns and the perceived quality of sleep, “sporting” women reported better sleep and less sleep. sleep disorders, including during the day.

In contrast, the study did not show an increase in the number of people listed as “good sleepers” after six months.

The measurement of complementary sleep obtained from an actigraphe, a physical activity recorder which analyzes, among other things, the cycles of sleep, showed no significant difference between the two groups, after three or six months.

In France, 54,000 new cases of breast cancer are diagnosed each year, at the average age of 63 years. Medical advances now make it possible to obtain 86% survival five years after diagnosis and 76% ten years later.
