A research paper that studied more than half a million cases of cardiac arrest has discovered a strong link between cold temperature and the risk of having a heart attack.
A heart attack is a serious medical emergency in which the supply of blood to the heart is suddenly blocked, usually by a blood clot. A study has found a link between cold weather and an increased risk of having a heart attack.
The study, published in the British journal Heart, found that a sudden cold snap can increase a person’s risk of having a heart attack.
Researchers found a strong link between chilly spells of weather and an increased in the potentially deadly condition.
Sudden chilly spells of weather were found to make blood vessels constrict, reducing the flow and triggering clots which can then lead to cardiac arrest.
Cold weather makes the heart work harder to keep the body warm.
The blood vessels constrict so the heart can concentrate on pumping blood to your brain and other major organs.
And because of this, it becomes harder for elderly people and very young children to regulate their own temperature.
Dr Diana Gall from Doctor4U further explained:
Common signs of heart attack include:
- Pressure, tightness, pain, or a squeezing or aching sensation in your chest or arms that may spread to your neck, jaw or back
- Nausea, indigestion, heartburn or abdominal pain
- Shortness of breath
- Cold sweat
- Light-headedness or sudden dizziness
