Air pollution linked to irregular menstruation

Air breathes in may be causing irregular menstrual cycles. Well documented negative health effects from air pollution exposure include infertility, metabolic syndrome and polycystic ovary syndrome. This study is the first to show that exposure to air pollution among teen girls (ages 14-18) is associated with slightly increased chances of menstrual irregularity and longer time to achieve such regularity in high school and early adulthood.

While air pollution exposures have been linked to cardiovascular and pulmonary disease, this study suggests there may be other systems, such as the reproductive endocrine system, that are affected as well," said corresponding author Shruthi Mahalingaiah, MD, MS, assistant professor of obstetrics and gynecology at Boston University School of Medicine and a physician in obstetrics and gynecology at Boston Medical Center.

The menstrual cycle is responsive to hormonal regulation. Particulate matter air pollution has demonstrated hormonal activity. However, it was not known if air pollution was associated with menstrual cycle regularity, until now. The researchers used health and location data gathered in the Nurses' Health Study 2 plus air pollution exposure metrics from the EPA air quality monitoring system to understand a participants' exposure during a particular time window. They found exposure to air pollution in during high school was correlated with menstrual cycle irregularity.

How to enjoy deep sleep without sleeping pills

Deep sleep is slow wave sleep, it is crucial for memory, physical renewal and hormonal regulation. It decreases with age and this can leads to memory loss.

New research says pink noise stimulation during sleep like water fall can boost memory and ability to remember past events.

Pink noise is like white noise, it is audible to humans, and it’s a type of sound in which every octave carries the same frequency.

Deep sleep is an innovative, simple and safe non-medication approach that may help improve brain health.

The degree to which slow-wave sleep improved correlated with the degree of improvement to memory, showing that deep sleep remains important even in older age.

Researchers matched gentle sound stimulation with an adult
brain waves, and timed it to enhance synchronisation of neutron activity.

The researchers believe pink-noise stimulation could be easily recreated at home. According to the National
Institutes of Health, older adults need seven to nine hours of sleep per night.

Researchers examined adults over 65 years and discovered 13 per cent of men adults, 36 per cent of women take more than 30 minutes to fall asleep. Good sleep can improve quality of life, sticking to a sleep schedule can help.
