International research shows that the risk of heart attack is 13% higher on Monday; The changes in stress, routine and sleep are among the possible causes
Monday is, for many, the most feared day of the week: end of rest, resumption of work and greater responsibilities. But science shows that this feeling goes beyond the simple laziness of starting the week. Studies indicate that the risk of heart attack on this day is 13% higher than the others.
What the research revealed
A survey conducted by Belfast Health and Social Care Trustin collaboration with the Royal College of Surgeons In IrelandThey analyzed the data of over 10,000 patients admitted between 2013 and 2018. All cases were related to the most serious type of heart attack. The myocardial infarction with the elevation of the ST (STEMI) segment, which occurs when a large coronary artery is completely blocked.
The researchers noticed a significant peak of occurrences on Monday, suggesting that the recovery of the routine after the weekend could be directly connected to this increase.
Why does it happen?
There is still no definitive explanation, but experts underline some main factors:
- Stress of the beginning of the week: Return to work or commitments can increase cortisol levels, the hormone related to stress and also the highest cardiovascular risks;
- Change in biological rhythm: Changes in the sleep cycle between the weekend and the beginning of the week can affect hormonal functioning and increase the vulnerability of the heart.
“The exact mechanism for these variations is unknown, but we assume that it has something to do with the way the circadian rhythm affects circulating hormones that can influence heart attacks and blows.”explained the cardiologist Jack LaffanHead of the study.
Situation in Brazil
Global data are echoed in the Brazilian reality. It is estimated that between 300 thousand and 400 thousand cases of acute myocardial infarction (AMI) per year in the country, which is the main cause of death between cardiovascular diseases.
According to Sus Records, between 2019 and 2022, the hospitalizations per heart attack grew by over 25%, from 81,500 to over 100 thousand. The National Institute of Cardiology has also shown that between 2008 and 2022, hospitalizations increased by 158% in men and 157% in women.
How to protect the heart
Despite the alarming numbers, it is possible to reduce the risks with changes to habits:
- Practical exercises regularly;
- Maintain a balanced diet;
- Avoid smoking and excess alcohol;
- Check the stress and make sure good sleep nights;
- Perform periodic medical checks.
On Monday it can also bring the fame of “heaviest day of the week”, but these data strengthen the need for constant care for cardiovascular health. Taking care of the heart is a daily investment and can make a difference to live longer.
