Srinagar, Jan 04: With continuous dip in temperatures to
sub-zero levels in Kashmir valley, Doctors Association Kashmir (DAK) on
Wednesday said chilly weather puts people at greater risk of high blood
pressure.
DAK president Dr Nisar ul Hassan said falling temperatures in winter cause hike in blood pressure which increases the risk of heart attacks and strokes, two leading causes of death and disability in the valley.
He said high blood pressure; also called hypertension is
harder to control in winter. “Even healthy people aren’t off the hook. They
tend to have high blood pressure in winter.”
“When winter arrives and temperatures drop, there is one
place where the mercury rises, that is in the blood pressure gauges,” he said.
The DAK President said frigid temperatures constrict
blood vessels which increase blood pressure because more pressure is needed to
force blood through narrowed vessels.
“Hormones, like adrenaline and nor-adrenaline increase in
response to cold and they cause spike in blood pressure,” he said adding that
lack of sunlight during winter reduces vitamin D levels which increases blood
pressure.
He said people are sedentary in winter, staying inside
and eating more that causes weight gain which contributes to hypertension.
“While we can’t change the weather simple precautions can
help reduce the risk of high blood pressure in winter. Keep yourself warm to
prevent from cold temperature. If you move out, dress in layers, wear a hat,
gloves and scarf. Avoid going in chill for walk and move your workout inside.
Reduce salt intake and take diet rich in vegetables and fruits. And, don’t
forget to take your vitamin D,” advised Dr Nisar
He added people who are on treatment for high blood
pressure need to monitor their blood pressure more frequently during winter as
they may need increase in doses or addition of drugs to keep their blood
pressure under control.
