Americans report these healthy habits have unintended side-effects

Having good intentions doesn't always translate to positive results — just ask the six in 10 people whose healthy habits have unintended side-effects, as a recent survey indicates.As part of a recent survey about health and air quality among 2,000 U.S. residents, 56% admitted that some of their good habits — including eating well, meditating, getting a full night's sleep and even cleaning — have caused unintended consequences in the past.For example, 34% have become anxious during a calming exercise; another 34% have woken up exhausted after a full night's rest.Two-fifths have felt ill after eating something healthy and a third have injured themselves exercising or staying active.And 40% of respondents have encountered physical side-effects after using a cleaning product in their home, while another 36% have been similarly triggered by a scented candle or aromatherapy device.

Conducted by OnePoll on behalf of air purification company Blueair, the study also found that one in 10 have opened a window and become more congested than before.
