Exercise helps to keep us in good health. Doctors at the American Heart Association suggest getting at least 150 minutes of proper physical activity every week. Many people exercise for a few minutes every day or every other day. So, getting 150 minutes every week is easy.
But what about those times when you are sick? If you do not feel well, should you keep following your exercise habit? Health experts answer these and other questions.
Edward R. Laskowski is a doctor at the Mayo Clinic. He and other experts have a general rule of yes about exercising when you are sick. It is usually fine to exercise, he explains, if your symptoms (症状)are all “above the neck". These signs may include a runny nose, a blocked nose, sneezing or a minor sore throat.
Geralyn Coopersmith is a physical fitness trainer who has written several books on exercise and nutrition. Both Coopersmith and Dr. Laskowski suggest taking a break from exercising if signs of your illness appear "below the neck". Pay special attention to symptoms such as chest congestion, extreme cough or pain in the stomach.
There are other symptoms that can tell you to avoid exercise. They include: a higher than normal body temperature, a sense of feeling extremely tired, and widespread muscle pain.
Both Coopersmith and Dr. Laskowski suggest listening to your body. If you feel really bad, take a break and let your body rest. If you don't feel too bad, these experts both suggest reducing the amount of exercise. For example, if you usually run, take a quick walk instead.

【推荐3】Your sleep position can determine a lot about your health, and can also affect your health in different ways.
It’s difficult to control what sleep position we naturally fall into, as our body will subconsciously fall into the most comfortable position. However, some positions are better for you than others, and some could actually hinder your health and wellbeing.
If you sleep on your side
More than 60 percent of people sleep on their side. This is mostly likely because it is one of the most comfortable sleep positions. Often our body naturally moves to this position, which is linked to when we were in the foetal (胎儿的) position.
Sleeping on your side offers a number of benefits to your body, from promoting healthy spine alignment, which can help to prevent back pain, to reducing heartburn and snoring. Side sleeping would be particularly beneficial for older people, those who snore or have sleep apnoea (呼吸暂停), those with back pain and pregnant women.
There are a few drawbacks to sleeping on your side, however. Those with shoulder pain and those who are worried about wrinkles should refrain from side sleeping.
If you sleep on your back
Lying on your back is the second most popular sleep position and offers just as many benefits as side sleeping.
When you’re sleeping on your back, your weight is evenly distributed, which helps prevent neck and back pain. Back sleeping would also be advised for those who want to keep their skin in good condition and those who suffer from neck and spinal pain.
However, back sleeping is the worst position if you snore or suffer from sleep apnoea. If you are a back sleeper, ensure you have a supportive pillow (枕头) which fits in the curve of your neck and supports your head and natural spinal curve.
If you sleep on your stomach
Sleeping on your stomach is the least common sleep position. There are more negatives to this position compared to positives.
The stomach offers the least amount of back support and can actually increase pressure on the spine which may cause pain once you wake up. Furthermore, those who sleep on their stomach will have their head facing one side, which may also cause a stiff neck upon waking.
Which sleep position is right for you?
Determining the right sleep position for yourself is personal preference. Regardless of which position you choose, make sure that you have a firm mattress and pillows. These will support the spine and neck, which is vital to prevent any pains in future.

【推荐3】Kunta is a small attractive stone-built town in England. Water is a natural gateway to the Cheviot Hills and the Northumberland National Park.

Therefore, the town is an excellent place for a holiday. It offers a wide range of accommodation, ranging from youth hostels(招待所), campsites to local hotels. The summer months see the town’s High Streets become a busy scene of local people and visitors. Each July the town holds its Glendale festival with a program of events spread over the weekend.

Today teenagers are using more and more smart phones. They spend too much time in shopping, chatting, playing games and so on. Many of them cannot stop using smart phones to help with their study.

【推荐2】Unhealthy health care bills, long emergency-room waits and inability to find a primary care physician just scratch the surface of the problems that patients face daily.
Primary care should be the backbone of any health care system. Countries with appropriate primary care resources score highly when it comes to health outcomes and costs. The U.S. takes the opposite approach by emphasizing the specialists rather than the primary care physician.
A recent study analyzed the providers who treat Medicare Beneficiaries(老年医保受惠人). The startling finding was that the average Medicare patient saw a total of seven doctors --- two primary care physicians and five specialists --- in a given year. Contrary to popular belief, the more physicians taking care of you don't guarantee better care. Actually increasing breakup of care results in a corresponding rise in costs and medical errors.
How did we let primary care slip so far? The key is how doctors are paid. Most physicians are paid whenever they perform a medical service. The more a physician does, regardless of quality or outcome, the better he's reimbursed( 返还费用). Moreover, the amount of a physician receives leans heavily toward medical or surgical procedures. A specialist who performs a procedure in a 30-minute visit can be paid three times more than a primary care physician using that same 30 minutes to discuss a patient's disease. Combine this fact with annual government threats to indiscriminately cut reimbursements, physicians are faced with no choice but to increase quantity to boost income.
Primary care physicians who refuse to compromise quality are either driven out of business or to cash-only practices, further contributing to the decline of primary care.
Medical students are not blind to this scenario. They see how heavily the reimbursement deck is stacked against primary care. The recent numbers show that since 1997, newly graduated U.S. medical students who choose primary care as a career have declined by 50%. This trend results in emergency rooms being overwhelmed with patients without regular doctors.
How do we fix this problem?
It starts with reforming the physician reimbursement system. Remove the pressure for primary care physicians to squeeze in more patients per hour, and reward them for optimally managing their diseases and practicing evidence-based medicine. Make primary care more attractive food to medical students by forgiving students loans for those who choose primary care as a career and harmonizing the marked difference between specialist and primary care physician salaries.
We’re at the point where primary care is needed more than ever. Within a few years, the first wave of 76 million Baby Boomers will become qualified for Medicare. Patients older than 85, who need chronic care most, will rise by 50% this decade.
Who will be there to treat them?
1. The author’s chief concern about the current U.S. health care system is_____.A.the inadequate training of physicians | B.the declining number of doctors |
C.the ever-rising health care costs | D.the shrinking primary care resources |
A.the more costly the medicine, the more effective the cure |
B.seeing more doctors may result in more diagnostic errors |
C.visiting doctors on a regular basis ensures good health |
D.the more doctors taking care of a patient, the better |
A.They find the need for primary care declining. |
B.The current system works against primary care. |
C.Primary care physicians command less respect. |
D.They think working in an emergency room tedious. |

【推荐3】In September 2019, a man named Anuchit was riding his motorcycle down a highway in Thailand. He spotted a sad-looking dog sitting on the side of the mud. The poor dog seemed to be waiting for someone.
Later that day, Anuchit rode by that exact same spot and found the same dog still sitting there. After stopping his bike to see if the dog was OK, Anuchit happened to meet a local person named Saowaluck, who told him the animal's backstory. Saowaluck kept finding the dog at that same corner in 2016. She brought him to the vet, named him Leo and adopted him. But days later, Leo disappeared. Sanwaluck found him at the same corner along the highway and returned every day to give him food and water. She loved him, but he wasn't ready to accept her as his new owner.
After the motorcyclist shared Leo's story on the Internet, the dog's former owner came forward. An elderly woman named Noi said Leo jumped out of her pickup truck back in 2015. She and her husband looked everywhere but couldn't find him. When Noi arrived at the corner to reunite with Leo in 2019, he ran over to her and was greeted with rubs and pets — but he refused to go home with her!
Saowaluck begged Noi to keep the dog herself because she had become so attached to him and had already tried to adopt him once before. Leo has reportedly been with Saowaluck ever since — no longer sad, and no longer waiting.
