Is Fresh Air Really Good for You?

We all grew up hearing people tell us to “go out and get some fresh air.” 1. According to recent studies, the answer is a big YES, if the air quality in your camping area is good.

2. If the air you’re breathing is clean—which it would be if you’re away from the smog of cities—then the air is filled with life-giving, energizing oxygen. If you exercise out of doors, your body will learn to breathe more deeply, allowing even more oxygen to get to your muscles(肌肉) and your brain.

Recently, people have begun studying the connection between the natural world and healing(治愈). 3. In these places patients can go to be near nature during their recovery. It turns out that just looking at green, growing things can reduce stress, lower blood pressure, and put people into a better mood(情绪).Greenery is good for us. Hospital patients who see tree branches out their window are likely to recover at a faster rate than patients who see buildings or sky instead. 4. It gives us a great feeling of peace.

5.While the sun’s rays can age and harm our skin, they also give us beneficial Vitamin D　 . To make sure you get enough Vitamin D—but still protect your skin—put on sunscreen right as you head outside. It takes sunscreen about fifteen minutes to start working, and that’s plenty of time for your skin to absorb a day’s worth of Vitamin D　 .

A.Fresh air cleans our lungs.

B.So what are you waiting for?

C.Being in nature refreshes us.

D.Another side benefit of getting fresh air is sunlight.

E.But is fresh air really as good for you as your mother always said?

F.Just as importantly, we tend to associate air with health care.

G.All across the country, recovery centers have begun building Healing Gardens.

The smell of fresh air is becoming something of a distant memory, thanks to our increasing use of fragrance (香气). From air fresheners to scented (有香味的) candles, we live in a world of scent.

Recent figures show seven in ten people use air fresheners or scented candles to keep our homes smelling sweet. Yet recent records suggest that perfumed products could affect our health, causing problems including allergies (过敏), headaches and asthma (哮喘) .

One leading expert believes nearly a third of people suffer health effects from being exposed to scents. A major problem is so-called “contact” allergy—where perfumes and scented products cause eczema (湿疹) when they come into contact with the skin. About one in 20 is thought to be affected by fragrance allergy.

“Often it may not be immediately obvious that you have developed a fragrance allergy,” says Dr. Baron. “You don’t react immediately. Gradually, as you are exposed more and more, the body increases its reaction, until it becomes noticeable to you.”

People with pre-existing eczema are particularly vulnerable (易受影响). “The eczema worsens in areas in contact with perfumes,” says Dr. Baron. “But even those without allergies can be at risk of fragrance allergy.” You can become suddenly allergic to perfumes and personal care products that you have been using for years. “Even if you know which fragrance causes a problem, it can be difficult to avoid, as most personal care products –soap, shampoo, sun cream and washing powder—contain fragrances,” says Dr. Baron.

And strong scents can also cause headaches. Fragrances activate the nose’s nerve cells, stimulating the nerve system associated with head pain. To minimize risk, sufferers are advised to minimize the contact.

“Fragrance suggest cleanliness – yet people are smelling a potentially dangerous chemical mixture,” says Anne Steinemann, professor of the University of Washington. “We often use them to mask one problem – as with air fresheners – but create a greater one – adding poisonous chemicals to the air.”
