Managing Blood Pressure During Extreme Heat Waves

At EASTSIDE FAMILY HEALTH CENTER in Kirkland, WA, we help patients manage heart and vascular health year-round—but extreme heat needs extra care. Dr. Frank Marinkovich, M.D., blends internal and functional medicine to help you keep your blood pressure stable when high temps and dehydration can send it swinging.
Why Heat Affects Blood Pressure
-
Hot weather makes blood vessels expand, which can lower blood pressure unexpectedly
-
Dehydration thickens blood, which can raise blood pressure in some people
-
Heat strain can worsen underlying heart or kidney conditions
-
Certain blood pressure medications (like diuretics) increase fluid loss and risk of dizziness
Why it matters: Sudden drops or spikes in BP can cause fainting, falls, or even strokes in high-risk patients.
Who’s Most at Risk During Heat Waves?
-
Older adults with chronic hypertension
-
People with heart disease, kidney disease, or diabetes
-
Anyone taking diuretics or beta-blockers
-
Those with low baseline blood pressure who get dehydrated easily
Tip: If you fall into these groups, have a plan when temps rise above 85°F.
Signs Your BP May Be Out of Balance
-
Feeling dizzy, lightheaded, or faint
-
Unexplained headaches or blurry vision
-
Weakness or sudden fatigue
-
Rapid heart rate or palpitations
Why it matters: These warning signs mean it’s time to check your numbers and adjust your routine.
How to Protect Your Blood Pressure in the Heat
-
Stay Hydrated – Drink plenty of water and consider electrolyte drinks if you’re sweating heavily
-
Avoid Peak Heat – Stay indoors during the hottest parts of the day (10am–4pm)
-
Monitor BP Regularly – Keep a home blood pressure monitor handy and know your safe range
-
