Cold weather can increase blood pressure

Scottish researchers have discovered an association between cold weather, low sunshine and heavy rain with the risk of hypertension.

They also found that patients with weather-sensitive blood pressure had a 35% increased risk of death, according to Scotsman.

For the above conclusion, scientists at Glasgow University analyzed 169,000 blood pressure readings of 16,000 patients from 1970 to 2011.

The results showed that, on average, blood pressure index in patients decreased by 2% / year if the weather in two consecutive visits were similar.

Meanwhile, if the temperature changed from the highest level to the lowest level in two consecutive visits, the patient's blood pressure increased by 2.1%.

In addition, the low level of sunlight leads to a 2.3% increase in blood pressure, and a lot of rain makes the blood pressure index increase by 0.8%.

However, the researchers found that many patients suffer from different effects of weather on blood pressure.

Research shows that patients with 'temperature sensitivity' control their blood pressure worst and have a 35% increased risk of death, compared with other patients.

Scientists reason that in good weather, patients feel comfortable, so blood pressure drops, while cold weather causes blood vessels to contract, causing blood pressure to rise.

From there, they asked doctors to take note of the weather when measuring patients' blood pressure. If a patient is found to be sensitive to temperature, the doctor will have reasonable treatment.

The Daily Mail quoted a British blood pressure specialist as saying that patients can still control their blood pressure in the traditional way, such as eating a lot of vegetables, fruits, eating less salt, limiting alcohol intake, and exercising. more.
