In the flu season, a flu shot is very important.
It is well known that the flu vaccine can help prevent influenza and protect vulnerable populations, such as pregnant women, young children, and the elderly.
Recently, a study published in JAMA finds that a flu shot also may help protect your heart health.
This is because people with high risk of heart disease tend to get flu easily, and flu can lead to respiratory failure, pneumonia, heart attack and/or stroke.
Flu can even worsen the existing health issues like type 2 diabetes, heart failure, and lung diseases.
Researchers from University of Kentucky suggest that flu can increase the development of clots in blood vessels. Flu may also provoke inflammatory changes that lead to heart attacks.
In this study, the researchers find that a flu vaccine can help reduce risk of heart attack, stroke, heart failure and other cardiac events by 30%.
Thus, they recommend that people who are 6 months and older should get a flu shot every fall. Although a flu shot will not cause flu, it can bring some side effects, including a mild fever, mild arm soreness, and muscle aches.
There are other tips for preventing the flu:
Avoid close contact. Try to avoid close contact with people who are sick. And if you are sick, keep some distance from other people so they won’t get sick.
Stay at home during sickness. When you are sick, try to stay at home and rest. Don’t go to crowed places like public transport stations, office buildings, shopping centers, etc.
Cover your nose and mouth. When you cough or sneeze, cover your mouth and nose. It will protect other people from getting the flu.
Clean your hands often. Cleanings your hands during the day can help protect you from germs. You can also use an alcohol-based hand rub if there is no water and soap.
