Swedish scientists warn that the lower the temperature, the higher the risk of heart attack. They analyzed the data of more than 250 thousand patients who were hospitalized with infarction, and can confidently say: winter contributes to heart disease.
The enemies of our hearts
Researchers from Lund University in Sweden analyzed data from 270 000 patients who were hospitalized with a diagnosis of “heart attack” for the period 1998-2013 Revealed the following patterns:
- When the temperature dropped below zero, the frequency of heart attacks has increased by 14%
- The wind increased the number of heart attacks by 7%.
- Reducing the duration of the photoperiod by an hour increased the number of people hospitalized with heart pain, 11%.
The accuracy of the identified dependencies have confirmed that warming of 7°C the risk of heart attacks decreased by 3%.
Why my heart hurts in the winter?
To explain the increase in the number of heart attacks in the winter, the doctors have put forward several versions. First, the changing nature of food – we always used more “heavy” of fatty foodswhen it’s cold. Second, many are forced in the winter to increase the level of physical activity. Foreign doctors have often noticed that heart attacks associated with snow removal. For residents of big cities it is less important, but the movement in the cold requires more physical effort. For older “cores” it can be a serious burden.
Thirdly, and here communication with the cold weather already straight, low temperatures cause spasm of the blood vessels. The heart has to work with the increased load, which leads eventually to a heart attack.
Finally, doctors have long known the phenomenon of the so-called cold pectoris. Many patients who have problems with heart and blood vessels, feel the pain in my chest when we go out from a warm room for cold street. This is especially noticeable phenomenon among people who are forced to move toward the cold wind.
What to do to avoid a heart attack?
To the winter to protect themselves from heart attacks, follow these guidelines:
- With the beginning of the cold season, consult a physician.
- Try to dress so as to minimize the risk of hypothermia. For example, wear several layers of thinner clothing rather than one thick sweater: the air gap will allow you to keep warm. And keep warm hands and feet, which cools the fastest.
- If you are forced to do physical work, being on the cold street (for example, to “dig out” the car, which during the night turned into snow), take breaks at work. If you rake the snow, take a small shovel with a short handle, this will reduce the load.
- Do not eat immediately after exercise is more increases the intensity of the heart.
