“Avoid exposure to secondhand smoke regardless of whether the smoker is still in the room,” said study author Professor Byung Jin Kim, of Sungkyunkwan University, Seoul, Republic of Korea. “Our study in non-smokers shows that the risk of high blood pressure (hypertension) is higher with longer duration of passive smoking — but even the lowest amounts are dangerous.”
Passive smoking at home or work was linked with a 13% increased risk of hypertension. Living with a smoker after age 20 was associated with a 15% greater risk. Exposure to passive smoking for ten years or more was related to a 17% increased risk of hypertension. Men and women were equally affected.
