Five Health Facts Your Doctor Wants You to Know

1. Cold weather makes you sick.

Myth! Germs (病菌) are the only thing that can make you sick. You can go out in the freezing cold with wet hair, and if there aren’t any germs around, you'll stay sniffle-free. But there is a correlation:1.

2. You shouldn’t ice a burn.

Truth! Most skin damage from a burn comes from the inflammatory (发炎) response, and ice can damage cells and make it worse. 2. Then wash with mild soap and apply an antibiotic (抗生素) ointment.

3. Antiperspirants (止汗剂) cause cancer.

Myth! Antiperspirants temporarily keep sweat from escaping, and some scientists have suggested that letting it build up in the ducts could cause tumors(肿瘤). 3. And the largest study to date on the subject has found no link between cancer and antiperspirants.

4.4.

Truth! A 2017 study found that when bystanders gave CPR to people in cardiac arrest (心脏停搏), survival rates were higher when they employed uninterrupted chest compressions rather than pausing for rescue breaths.

5. Eating too much sugar will give you diabetes.

Myth! Sweet foods don’t directly lead to chronically (慢性地) high blood sugar. But they can contribute to obesity, which is a risk factor for diabetes. 5.

A.Germs are active if you have a cold.

B.But research hasn’t confirmed that theory.

C.CPR doesn’t require mouth-to-mouth breathing.

D.Therefore, it’s inappropriate to deal with the burn with ice.

E.Instead, first immerse the burn in cool water for about five minutes.

F.So keeping a well-balanced diet and limiting treats is still the right idea.

G.The germs that cause the common cold grow energetically in low temperatures.

Seven Health Facts about Coffee

When you’re considering your morning coffee, here are some health facts to keep in mind:

1. Coffee Reduces Your Risk of Diabetes (糖尿病)

In a 2005 review of nine studies, researchers found that for those that drank four to six cups of coffee per day, versus only two or fewer, their risk for Type 2 diabetes decreased by almost 30 percent. The number decreased by 35 percent when people drank more than six cups per day. And if you’re picturing yourself running around the office with your eyes bugging out of your head, no worries because caffeinated and decaffeinated coffees provided much the same results.

2. Coffee Fights Free Radicals (自由基)

We often forget that coffee is actually a plant and like all plant foods, the coffee bean contains more than 1,000 naturally occurring substances called phytochemicals, which may help prevent disease. Many of these phytochemicals are antioxidants which protect the cells from damage from free radicals.

3. Coffee Improves Memory and Cognition

Researchers reported that volunteers who drank caffeinated coffee in the morning performed better than nondrinkers on tests that involved learning new information. Coffee can also improve cognitive function as we age. One study found that combining coffee with a sweet treat had an even bigger impact.

4. Coffee Can Increase Osteoporosis (骨质疏松)

It’s true that coffee can cause the body to excrete calcium in urine. We don’t want the body to rid itself of calcium because this can lead to osteoporosis. According to The Diet Channel, about five milligrams of calcium is lost per every six ounces of coffee consumed. But these calcium losses can be counter balanced with two tablespoons of milk or yogurt per cup of coffee.

5. Coffee Causes Wrinkles

Even though coffee has antioxidants, if you drink too much of it, it can cause wrinkling of the skin. This is a result of dehydration (脱水) which is the worst thing for your skin. So when you’re drinking that morning cup or two, make sure that you’re pairing it with water. Even better, add one tablespoon of chia seeds to your water and let them sit for 30 minutes. The chia seeds keep you even more hydrated than regular water.

6. Coffee Can Actually Cause Weight Gain

The blood sugar changes that a caffeine high produces can contribute enormously to a strong desire for it, according to iVillage. Coffee is also socially connected to food. For example, we pair coffee with dessert or that morning powdered doughnut. Additionally, when we crash from our caffeine high that’s when we reach for all sorts of fatty snacks to keep us going.

7. Conventional Coffee Is Laden with Pesticides (杀虫剂)

The coffee plant is one of the most heavily sprayed crops. It’s coated with chemicals, pesticides, and herbicides, nothing you’d want to be swallowing. If you do drink coffee, make sure that it’s the organic variety, free from assorted chemicals that leech into our ground water and can make us sick down the road.

If you switch to decaffeinated coffee, make sure the caffeine (咖啡因) is removed in a natural way without the use of chemicals to do it. Often times, conventional decaffeinated coffee has more chemicals than regular.

1.   If you want to decrease the risk of diabetes by 35%, you need to take at least _____ cups of     coffee every day.

2.If you are a heavy drinker of coffee, a far better way to avoid wrinkling of your skin is to drink water _____.

3.   Which of the following statements is wrong?

4.   The author has a/an _____ attitude towards drinking of coffee.

“You’ll be blind by the time you’re twenty-five,” a doctor at Children’s Hospital predicted. “Your blood sugars are much too high.” It consumed me. No matter where I was or what I was doing, it was overhead like a dark cloud, waiting for just the right opportunity to break open and destroy my world.

I liked painting. Losing myself in painting filled me with peace. Painting provided me with the only place where I could escape from those threatening words.

When I was twenty-one, my right eye went blind. Precisely three months after my twenty-fifth birthday, I had a massive hemorrhage (大出血) in my left eye because of an accident. For the next twenty years, vision came and went. I went through many eye operations in an attempt to keep my vision. But after one final operation, I lost the battle and all remaining vision. And I buried all dreams of painting.

Desperate, I enrolled in (注册) a sixteen-week program for the blind and visually impaired (损伤的). I learned personal adjustment and the use of a computer with adaptive software. A whole new world opened up to me through this program.

“Jaws and Window-Eyes are leading software for the blind,” my instructor told me. “You can use the Internet, e-mail and Microsoft with all its tools and features.” It’s amazing! Hope went up for the first time in years. “By learning how to use hot keys to control the mouse, you can use Microsoft Access, Excel and Powerpoint,” my instructor added.

For the next several years, I learned that when one door closes, another door opens. There are plenty of choices available for the blind and visually impaired through the gift of technology. Not only do I have a speaking computer, but I have a speaking watch, alarm clock and calculator.
