Is taking a daily aspirin smart or dangerous?
Whether a daily aspirin is smart or dangerous depends entirely on your age and medical profile. Take aspirin only on a doctor's advice and never stop or start it on your own.
A daily low-dose aspirin is a proven protection for some people and a real risk for others. Based on large studies, the American preventive health task force USPSTF has issued clear recommendations for both situations. These differ considerably by age group.
If you are between 40 and 59 years old with an elevated cardiovascular risk, specifically a 10% or greater chance of a heart attack or stroke within ten years, the evidence shows a small but real benefit. The USPSTF does stress that this is a personal decision. People who have no elevated bleeding risk and take aspirin consistently have the greatest chance of a net benefit. The effect is modest, not spectacular.
Are you 60 or older without known cardiovascular disease? Then the USPSTF message is unambiguous: do not start. The risk of serious bleeding, such as in the stomach or brain, outweighs the possible benefits. That is not a cautious assumption but an explicit conclusion based on multiple studies in humans1.
Around non-cardiac surgery, routine aspirin use is also inadvisable. Studies in humans show that it does not reduce the chance of cardiac complications but does increase the risk of bleeding during the procedure2.
There are situations in which aspirin is clearly beneficial. In pregnant women at high risk of pre-eclampsia, low-dose aspirin lowers the risk of that complication, of preterm birth, and of harm to mother and child3,4. In the rare platelet disorder essential thrombocythemia, aspirin is recommended to prevent blood clots. European gastrointestinal specialists also state that aspirin may offer some protection against stomach cancer in people who already have a high cardiovascular risk, although that evidence is more limited and explicitly applies to a select group.
All claims are based on guidelines and reviews: USPSTF 2022, ESGE/EHMSG/ESP 2023, and a perioperative study (PMIDs 35471505, 32692391, 40112834, and 38269572). No raw research data directly available; the strength of evidence per subgroup is moderate.
Is loud snoring dangerous for my health?
Loud snoring is associated with serious health risks: arterial calcification, higher mortality after a heart attack and dangerous daytime sleepiness. If you snore loudly on a regular basis and feel tired during the day, have it checked by your general practitioner.
Is coffee healthy or unhealthy?
For healthy adults, moderate coffee consumption (3 to 5 cups per day) is more likely to be healthy than unhealthy; if you are pregnant or prone to anxiety, moderation or consultation with your doctor is advisable.
Is atrial fibrillation dangerous, and what can I do about it?
Atrial fibrillation substantially increases your risk of death, heart failure, and stroke, and requires active treatment. Discuss blood thinners for stroke prevention with your doctor, as well as which lifestyle changes are worthwhile in your specific situation.
Is high blood pressure at night more dangerous than during the day?
High blood pressure at night is more dangerous than a high daytime reading at the doctor's office. If your blood pressure does not drop enough at night, or even rises, your risk of a heart attack, stroke or heart failure is considerably higher, even if the reading at the practice looks perfectly fine.
Does sitting all day increase your risk of heart problems?
Sitting a lot increases your risk of heart failure and heart-related mortality, even if you exercise regularly. Just 30 minutes less sitting per day produces a measurable improvement, so try to break up long periods of sitting regularly.
Is coffee good or bad for your heart?
For most healthy adults, three to four filtered cups per day are associated with a beneficial effect on the heart and blood vessels. Pregnant women are an important exception: for them, the maximum is one to two cups per day.
