As little as 30 minutes exposure to secondhand smoke could cause blood vessel damage.

Those who do not smoke can suffer impaired blood vessel function with as little as 30 minutes of exposure to secondhand smoke. Researchers used concentrations similar to those encountered in real-life circumstances. This study reinforces the danger smokers pose to other people, let alone their own health.

PositiveTip: Support efforts to ban smoking in all public places--and avoid inhaling some one else's smoke.

Adolescence and adult exposure to secondhand smoke increases risk of hearing impairment

Second hand smoke (SHS) associated hearing losses of 15 dB or greater in adolescence is found to be proportional to the level of exposure. In adult former smokers SHS exposure risk, of at least a 25dB impairment, increased 30% and 40% for low/mid and high frequencies, respectively. Never smokers hearing impairment risk increased by 14% for low/mid frequencies.

PositiveTip:  Avoid smoking and second had smoke to prevent tobacco smoke related hearing problems.
