The volunteers didn’t know which type of air they were breathing, but when it included candle smoke, their heart rate variability【C5】______.
Everyone’s heart rate varies【C6】______all the time, beating a little bit faster when we breathe in than when we breathe out This is perfectly healthy and a sign that the brain is【C7】______and able to regulate the heart But this variation【C8】______as we get older and if we【C9】______heart problems. In the study, it was increased by【C10】______candle smoke.

As the volunteers could not see the candles and weren’t told what they were breathing, the effect could not be explained【C12】______by the calming effect of candlelight.
Dr Isaxon believed that tiny particles of the candle smoke could be responsible for the beneficial effects. These particles are【C13】______regulating the heart’s rhythm and in sending messages between cells in the body. More salts are produced when a【C14】______is still. The study did not find any【C15】______health effects of the smoke—【C16】______she admitted she did not ’make a huge effort’ to find any.
Soot, black powder in the smoke, from lit candles has been【C17】______health problems in the past. The American Chemical Society has warned that common wax candles release【C18】______harmful chemicals linked to cancer and other illnessea It recommends using beeswax.

选项
A、measuring
B、emitting
