CHICAGO — As spring routines shift across Chicago and surrounding communities, Illinois health officials are urging residents to pay attention to a condition that often develops without warning: high blood pressure.
Often referred to as the “silent killer,” high blood pressure rarely causes noticeable symptoms while significantly increasing the risk of heart attack, stroke and kidney disease. Health experts warn that seasonal transitions — including changes in physical activity, diet, stress levels and sleep patterns — can quietly influence blood pressure numbers.
“Most people assume they would feel it if something was wrong,” officials say. “With hypertension, that’s typically not how it works.”
Nearly half of U.S. adults live with high blood pressure, and many do not know they have it. In Illinois, cardiovascular disease remains a significant public health concern, particularly in densely populated urban areas where stress and lifestyle factors may compound risk.
Spring in Chicago brings fluctuating temperatures, longer daylight hours and shifting daily schedules. Some residents increase outdoor activity, while others experience disrupted sleep, commuting stress or travel. Seasonal allergies, hydration changes and inconsistent routines may also affect the body. Officials say these combined factors can influence blood pressure — even among individuals who feel healthy.
Doctors emphasize there is no reliable way to detect high blood pressure without measuring it. Readings of 180/120 or higher, especially when accompanied by chest pain, shortness of breath, vision changes or weakness, require immediate medical attention.
Health officials encourage Chicago residents to use the seasonal transition as a reminder to check their blood pressure and consult a healthcare provider about recommended screening.
“You can’t rely on how you feel,” officials say. “You have to know your numbers.”
