The average age for women to enter the menopause – where their oestrogen levels begin to fall – is 51, though the age range can stretch from 45 to 55.
A now new research has revealed a surprising factor that can trigger this process, and it’s all to do with where you live.
Publishing their findings in the journal Environmental International they found that women living in green spaces went into the menopause on average 16 months later than their urban counterparts.
The study featuring the above women began in 1990 and surveyed the women again between 1999 and 2001 and 2010 and 2013, covering a period of more than 20 years in total.
The women came from Spain, France, Germany, Belgium, the UK, Sweden, Estonia, Iceland and Norway and satellite images were used to determine how much green space they had in the vicinity of their home.
They concluded that women living with the most foliage in the 300m (985ft) encompassing their home experienced ‘the change’ aged 51.7 years of age, compared to a figure of 50.3 years of age for those women with the least amount of green space surrounding their home.
And the above was even after adjusting for smoking and factors related to socioeconomic status.
The research team indicate that this trend may be due the fact that stress and even depression can induce menopause at an earlier date, and that those living in green, rural areas may experience less of both due to the potentially calming nature of the environment they live in.
They wrote, ‘Stress in humans is reflected by a high level of cortisol, which is reduced by exposure to greenspace’.
They also went on to outline that stress and a result cortisol can impact levels of oestradiol – a form of the female sex hormone oestrogen – causing it to reduce where cortisol levels are high.
‘Lower cortisol levels have in turn been associated with higher oestradiol levels, which makes it plausible that women with less stress, thus lower cortisol, might maintain higher oestradiol levels and therefore transition later into menopause,’ the researchers outlined.
