1 . Back pain can make it difficult for many people to function in everyday life.
Our bodies need adequate movement throughout the day to avoid the stiffness that contributes to aches and pains. If the weather is good, don't hunt for the nearest parking spot; don't take the elevator when you have the option of one or two flights of stairs. When you need to sit for long periods, set a timer to get up every hour and be active for just a few minutes.
When we overuse our dominant side, we create muscle patterns of weakness and tension that increase pain, especially in our backs. Consider the actions you take repeatedly throughout the day that shift your weight to one side.
Psychological stress is a noted risk factor for back pain, according to research. Most mental stress is caused by focusing on the past or future.
A.Switch sides when you carry things. |
B.It affects how you move, feel and think. |
C.You should learn more about the cause of your pain. |
D.Approach the health of your back as a responsibility. |
E.So actively being mindful of the present reduces stress. |
F.You'd better take a quick break to check in with your breathing. |
G.More minutes of movement add up to big health benefits over time. |
2 . “Just think positively!”
“It could be worse.”
“You should look at the bright side!”
We’ve all heard (and maybe used) these phrases without much thought. But they could be contributing to a culture of toxic(有毒的) positivity. For those new to this term, it might sound like an oxymoron(矛盾修辞法). How can positivity be toxic? Isn’t it supposed to be helpful, or “positive”, as the name suggests?
“Toxic positivity is when somebody avoids all negative thoughts or feelings, pretending everything is going well when it is not,” explains Melissa Dowd, a therapist at PlushCare, a virtual health platform for primary care and mental health services.Whitney Goodman, the author of Toxic Positivity describes toxic positivity as the “endless pressure to be happy and positive, no matter what the circumstances are.”
Expressing toxic positivity to others may look like offering them a simple solution to a complicated problem that we know nothing about, or not allowing people around you to appropriately express negative emotions.
Toxic positivity causes us to suppress our emotions, which can make them worse.
A.Are there ways to avoid toxic positivity? |
B.Toxic positivity also disrupts connection. |
C.It can harm people who are going through difficult times. |
D.This can come up in different situations when we are dealing with pressure. |
E.They become more intense and can cause long-lasting health concerns in the future. |
F.Experts say constant forced positivity can lead to the opposite, and have a negative effect. |
G.This is what we may bring on to ourselves by not allowing negative thoughts and feelings. |
3 . Has anyone ever told you, “Stand up straight!” or scolded you for sitting lazily at a family dinner? Comments like that might be annoying, but they’re not wrong.
If your posture isn’t good enough, your muscles have to work harder to keep you upright and balanced. Some muscles will become tight and inflexible.
So what does good posture look like? If you’re sitting, your neck should be vertical, not tilted forward. Your shoulders should be relaxed with your arms close to your trunk. Your knees should be at a right angle with your feet flat on the floor. But what if your posture can’t be that great?
It’s also not enough to just have good posture. Keeping your muscles and joints moving is extremely important. In fact, being still for long periods with good posture can be worse than regular movement with bad posture.
A.Try redesigning your environment. |
B.You adjust your body unless you feel tired. |
C.So if you sit a lot, get up and move around on occasion. |
D.And the big one that we all experience every day is gravity. |
E.Besides, poor posture leads to extra wear and tear on your joints. |
F.Posture can even influence your emotional state and your sensitivity to pain. |
G.Your posture refers to the way you hold your body when you’re sitting or standing. |
4 . While many people aren’t getting enough calcium (钙), new research cautions that some people may have the opposite problem: They could be getting too much. Americans spend more than $1 billion a year on calcium supplements (补充剂) in hopes of delaying osteoporosis, the brittle bone disease that cripples many elderly women and some men. Yet recent studies link calcium supplements to a higher risk of heart attacks. Last month, the U. S. Preventive Services Task Force issued a draft recommendation against taking calcium and vitamin D, saying there wasn’t enough evidence of benefit to justify the risk.
For generations of Americans who grew up encouraged to drink milk to maintain strong bones, the reports raised troubling questions: Is calcium not so important after all? Are the supplements unsafe? And how much is too much? “It’s gotten very confusing but it doesn’t need to be,” says Ethel Siris, director of the Toni Stabile Osteoporosis Center in New York. How much calcium people need varies by age and gender. “Adults generally need 1,000 mg daily, rising to 1,200 mg for women over 50 and men over 70, according to guidelines issued in 2010. Children need 1,300 mg daily during the peak growing years of 9 to 18. ”
People also need sufficient levels of vitamin D to absorb the calcium. The IOM recommends 600 international units a day for most adults, and 800 daily after age 70, although many physicians recommend more. It is difficult to take in that much vitamin D from food sources, so experts say many people should take vitamin D in supplement form.
Getting adequate (充足的) calcium from food is easier. For example, 8 ounces of milk or 6 ounces of yogurt has 300 mg of calcium, and one cup of spinach has 270 mg.
But studies linking calcium supplements to heart attack have made experts more cautious of excess calcium than before. A study of 24,000 Germans published in the journal Heart last month, found that those who got their calcium exclusively from supplements were more than twice as likely to have a heart attack as those who took no supplements.
Exactly how calcium supplements might contribute to heart attacks baffles cardiologists (心脏病学家). “Nobody has associated the calcium in your bloodstream with calcification (钙化) in your arteries,” says Nieca Goldberg, medical director of the Joan H. Tisch Center. Still, she says she now urges patients get their recommended calcium from food than from supplements to avoid possible problems.
Osteoporosis experts also urge patients not to take more than the recommended amount of calcium. “People should definitely stop taking two big calcium supplements a day,” says Dr. Dawson-Hughes. Even if the risks remain unclear, taking more than the body can absorb doesn’t benefit bones, “so it’s not worth any risk. ” She adds.

5 . Many people don’t treat themselves very well. They break promises to themselves, eat poorly, don’t get enough sleep, are self-critical or fail to take good care of their bodies.
A great technique for treating yourself better is by developing your Inner Nurturing Parent. Imagine you had a little child. You’d make every effort to keep her healthy and safe; to love and support her; to be forgiving her mistakes and her inevitable slips; and to let her know how precious and important she is.
Take good care of yourself. A loving parent would make sure you eat right and get plenty of rest sleep, fresh air and exercise.
Set healthy boundaries with others. Let people know what you want and don’t want. Tell them what’s okay for you and what’s not. If you have a friend who’s always late and you end up waiting for her and feeling annoyed, tell her how you feel.
Be concerned about yourself.
A.Cheer yourself up constantly. |
B.A nurturing parent. wouldn’t let someone treat you badly. |
C.Have sympathy for your humanity and your weaknesses. |
D.That’s what a loving parent does. |
E.You should always regard yourself as a child. |
F.Send loving messages to yourself. |
G.Keep yourself healthy and fit. |

7 . Late-night eating has long been connected to a higher risk for obesity or overweight, which can pose all kinds of risks to your heart.
The study was rather small, featuring only 16 overweight or obese people.
The solution may be relatively simple. Keeping your eating schedule in line with your body’s natural clock makes sense.

B.Researchers may have learned why meal timing could impact fat gain. |
C.A survey has revealed that a growing number of people are overweight. |
D.They each stuck to a strict early or late meal schedule for one day in a lab. |
E.Remember, what you eat and how much is likely more important than when. |
F.Eating more early in the day and less as it progresses may be the best strategy. |
G.The study found that leptin dropped by 16 percent when people delayed their meals. |
8 . Lots of people find it hard to get up in the morning and put the blame on the alarm clock. In fact, the key to easy morning wake-up lies in resting your body clock
•
• Rethink mornings. Now that you know why you want to wake up, consider re-arranging your morning activities. If you want time to have breakfast with your family, save some time the night before by setting out clothes, shoes, and bags.
• Keep your sleep/wake schedule on weekends. If you’re tired out by Friday night, sleeping in on Saturday could sound wonderful. But compensating (弥补) on the weekends actually feeds into your sleepiness the following week, a recent study found.
• Keep a record and evaluate it weekly. Keep track of your efforts and write down how you feel. After you’ve tried a new method for a week, take a look at your record.
A.Get a sleep specialist. |
B.Find the right motivation. |
C.A better plan for sleep can help. |
D.And consider setting a second alarm. |
E.If the steps you take are working, keep it up. |
F.Stick to your set bedtime and wake-up time, no matter the day. |
G.Reconsider the 15 minutes you spend in line at the cafe to get coffee. |
Is it better for our bodies to work out at certain times of the day? Scientists have known for some time that every tissue in our bodies contains a kind of biological clock that goes off in response to messages related to our daily exposure to light, food and sleep.
However, whether and how exercise timing might influence metabolic(新陈代谢的)health has been less clear, and the results of past experiments have not always agreed. A much-discussed 2019 study found that men with Type 2 diabetes(糖尿病)who completed a few minutes of high-intensity interval(间隔)sessions in the afternoon improved their blood-sugar control after two weeks. Patrick Schrauwen, a professor of nutrition and movement sciences read that 2019 study with interest. He had been studying exercise in people with Type 2 diabetes, but had not considered the possible role of timing. Now, seeing the varying impacts of the intense workouts, he wondered if the timing of workouts might similarly affect people’s metabolisms.
Incidentally, he and his colleagues had a ready-made source of data in their own prior experiment. Several years earlier, they had asked adult men at high risk for Type 2 diabetes to ride stationary bicycles at the lab three times a week for 12 weeks, while the researchers tracked their metabolic health. They also had noted when the riders showed up for their workouts. The researchers pulled data for the 12 men who consistently had worked out between 8 and 10 a.m. and compared them with another 20 who always exercised between 3 and 6 p.m. They found that the benefits of afternoon workouts far outweighed those of morning exercise.
He says, “This study does suggest that afternoon exercise may be more beneficial for people with disturbed metabolisms than the same exercise done earlier. The particular and most effective exercise for each of us will line up with our daily routines and exercise tendencies because exercise is good for us at any time of day — but only if we choose to keep doing it.”
