Cold weather poses a threat to young people as well. The cold temperatures can cause blood vessels to constrict, leading to unstable blood pressure and increased burden on the heart.

This is partly because young people often lack self-monitoring and self-protective awareness. Even when experiencing symptoms like headaches or chest discomfort, they may not immediately consider cardiovascular diseases as a potential cause and may not take them seriously.

Moreover, some individuals have irregular lifestyles, consume excessive junk food, stay up late, and engage in alcohol consumption and smoking, which can damage blood vessels. Additionally, if they are in high-pressure situations, the sympathetic nervous system goes into a stress state, causing increased oxygen consumption by the heart, heightened vascular tension, elevated blood pressure, and increased resistance when the heart pumps blood out. If the coronary arteries are already ischemic under these circumstances, it can lead to discomfort or even pain in the heart.

5 warning signs of sudden cardiac death:

Chest pain associated with activity: If symptoms worsen during physical exertion or emotional stress and subside with rest, it could be a sign of angina or a heart attack.

Unexplained changes in symptoms: If patients with coronary heart disease or angina experience an increase in the frequency or intensity of symptoms that are difficult to relieve, they should be highly alert to the possibility of a heart attack.

Sudden palpitations and chest discomfort without warning signs: People without heart disease suddenly experiencing chest discomfort, palpitations, or unexplained even at rest,should be suspected of myocardial ischemia and should seek early medical examination and treatment.

Feeling dizzy, fatigued, or experiencing palpitations after staying up late could be a sign of cardiovascular or neurological distress.

Syncope or fainting: Fainting is an important precursor to sudden cardiac death in patients with heart disease. Most cases of syncope occur due to sudden slowing or cessation of heartbeats, resulting in insufficient blood supply to the brain. If unexplained syncope occurs, it is essential to promptly seek medical attention to determine the cause.

Winter is a season of increased incidence of cardiovascular diseases. It is important for everyone, especially those with older adults or individuals with chronic conditions in their homes, to be vigilant and take extra precautions.
