Conducted by researchers from Scotland study found that differences in blood pressure at the onset of bad weather can worsen the person's state of health or even kill him. A sharp drop in temperature is also not the best effect on health.
It is known that sudden change of blood pressure associated with high risk of heart attack and stroke, which accounts for the largest number of deaths in developed countries. And weather conditions such as rain and cold, have a negative impact on blood pressure. Researchers found that blood pressure and bad weather are interrelated, and the pressure changes as the temperature changes.
The researchers compared data on blood pressure West of Scotland over the past 40 years with the meteorological records for the same period. In the result, it was found that the impact of bad weather on 1/3 increases the risk of death from stroke and heart attack. This is because of the cold, the vessels constrict to conserve heat, which leads to increased blood pressure.
In this regard, the researchers recommend that doctors often more closely examine the interconnectedness between bad weather and pressure that will give the opportunity to identify patients that are weather-sensitive. In this case, treatment may need to be adjusted.
The decline in atmospheric pressure by 2 mm Hg, significantly increases the risk of heart attack or stroke at weather-sensitive patients. Earlier studies have established that the peak mortality from cardiovascular diseases account for the cold season: late fall, winter, early spring. That is why scientists from Scotland intend to conduct a more detailed study of this phenomenon.
