Wednesday Bubble: weathering your hot flashes

Hey Ladies! This week’s bubble comes to you c/o my Twitter friend Gloria Bell, who asked an interesting question: does climate affect hot flashes?

Apparently it does. Although there are not a lot of studies that have been conducted specifically on this topic, an extensive analysis of data from 54 studies suggests that climate may indeed, influence the frequency of hot flashes. Investigators focused the mechanisms underlying hot flashes ( i.e., small elevations in core body temperature within a temperature range where a woman would not normally shiver or sweat –also called the thermoneutral zone), hypothesizing that these zones might actually be climate-specific.

The study:

• Researchers examined information on the frequency of hot flashes from 54 studies and evaluated the correlations between hot flash frequency and geographical latitude, elevation and annual temperatures. Additional analyses were conducted on data derived from studies that included women no older than age 60.

What they learned:

• Among women up to age 60, the average temperature of the coldest month could actually predict how frequently women experienced hot flashes almost a third of the time.
• Among all women, the difference between the hottest climates and the coldest climates significantly predicted hot flash frequency about 26% of the time.
• A climate’s mean annual temperature also predicted hot flash frequency.

Overall, women who lived in warmer temperatures tended to report fewer hot flashes than those in the coldest regions. Hot flashes also tended to increase in areas where there were more seasonal fluctuations.

Although climate plays a role, other factors, such as hormonal imbalance, smoking and diet have also been shown to influence hot flash severity and frequency. Still, it is interesting to learn that where we live may influence the challenges we may face when weathering the menopause storm!
