空汙期間
最好做室內運動
●Weighing up the benefits of exercise is usually pretty straight-forward: doing something anything is better than nothing.衡量運動益處通常很直觀：做點運動，或者說做任何運動比什麼都不做來得好。
●But, for many of us, maintaining fitness and being physically active outdoors has recently become more complicated.不過對我們多數人來說，維持健美身材和在戶外活動最近卻變得越來越複雜。
●As fires blaze in parts of Australia, and dozens of communities fight to protect their lives and homes, many are living with smoke haze and thick smog.大火在澳洲多處肆虐，數十個社區奮力保護他們的身家性命和房屋之際，許多人也生活在霧霾和濃煙
之中。
●NSW is now in the grips of its longest and most widespread period of poor air quality on record, and data shows Sydney’s air quality is three times worse this bushfire season than at any time in the past five years.新南威爾士州（NSW）現在正處於史上最久又最廣泛空汙品質的不利環境中，而且數據顯示，目前雪梨的空氣品質比過去五年野火季的任何時刻都還糟三倍。
●Bushfire smoke poses a range of health issues, and the best way to avoid it (generally speaking) is to stay inside.野火濃煙引發許多健康問題，一般來說，避免空汙的最佳作法就是待在室內。
●But with fires expected to continue for some months, how can we keep fit and active, while managing the risks to our health?但大火預計持續數個月，我們要如何維持健身和運動，同時管控我們的健康風險？
●Bushfire smoke irritates the respiratory system, and contains fine particles that can travel deep into the lungs, causing damage.野火煙霧刺激呼吸系統，而且含有細微顆粒可深入肺部造成損害。
●If you’re healthy you can probably tolerate being exposed to air pollution for short periods (though it may cause itchy eyes and throat irritation), but smoke particles can aggravate respiratory conditions (such as asthma), and even trigger a heart attack or stroke.如果你身體健康，也許能忍受短期暴露在空汙中（雖然空汙可能造成眼睛發癢和喉嚨痛），但煙霧顆粒可能加重呼吸症狀（例如氣喘） ，甚至引發心臟病或中風。
●When air quality is low, it’s important to minimise your exposure. That means where possible, keep your workouts indoors.空氣品質低落時，降低暴露在空汙中很重要；這代表如果有方便的地方就在室內運動。
●”It’s safer to exercise indoors, there’s no doubt about that,” says Sotiris Vardoulakis, Professor of Global Health at the Australian National University. “If people have access to indoor sports facilities, it would be better exercise indoors.”澳洲國立大學研究全球健康的教授瓦多拉基斯（Sotiris Vardoulakis ）表示：「毫無疑問地，在室內運動會比較安全。如果民眾有室內的運動器材，那麼你最好從事室內運動。」
