The study of Moudi et al  highlights the influence of lifestyle on sleep quality in Iranian postmenopausal women. The authors emphasize that demographic variations are responsible for different results worldwide. We agree with this statement and would like to share and compare results from our center, located in Sao Paulo, Brazil.
The influence of exercises on sleep is noteworthy. For instance, post- menopause women practicing yoga have less insomnia complaints . This can be due to an interaction with the neuroendocrine and autonomic nervous systems, which lead to improved sleep patterns and less vasomotor symptoms . Nevertheless, patients practicing passive-stretching exercises did not have significant improvement .
There is also an influence of therapeutic massage and acupuncture in sleep architecture. Patients undergoing these interventions have a higher percentage of the N3 and N4 stages of sleep [4–6]. Massage also improves sleep efficiency  and well being upon awakening .
Regarding constitutional characteristics, obese women have more obstructive sleep apnea and difficulty to reach rapid eye movement (REM) stage . A deep sleep is important for memory and body and mind restitution . They also have a tendency of eye problems, such as floppy eyelid syndrome (FES) and discomfort on waking. There is an association between FES and sleeping posture and laterality adopted by the patient .
We would also like to point out that the amount of years after the menopause is an important factor to take in consideration. We have observed that patients in late post-menopause have more subjective complaints related to sleep, such as daytime sleepiness .
Postmenopausal women have more sleep disturbances than younger individuals . The knowledge of lifestyle factors that influence sleep is important to afford a complete therapeutic management of this population.
