New research suggests that Christmas time may actually increase the risk of heart attack. According to a Swedish study entitled "Christmas 2018: Heart Disease" published in the medical journal BMJ, an analysis of hospital admissions for 16 years of myocardial infarction revealed a link between external factors and medical emergencies. The results show that Christmas, midsummer and other major holidays are associated with a high risk of myocardial infarction, especially in elderly and heavier patients.
Many factors can lead to increased cardiac arrest, from emotional stress to severe physical activity to cold weather exposure, and the study hopes to determine whether external factors such as holidays are directly related to the disease. The team used the SWEDEHEART database on Christmas Eve, the online registration of medical information from all over the country, the chance of heart attack is 37% higher than normal, and peaked around 10 pm.
On the positive side, the study also found that major national and international sporting events like the World Cup had little impact on the increase in heart attacks. This means you can safely watch a variety of major sporting events.
