1 . Lack of sleep can be compensated for by exercise
Staying active and fit could help to ward off some of the negative health impacts that would normally result from low-quality sleep, according to a large study of 380,055 middle-aged people involved in the UK Biobank research project.While the health benefits of exercise and sleep are nothing new,
"We found those who had both the poorest sleep quality and who exercised the least were most at risk of death from heart disease, stroke (中风), and cancer," says epidemiologist Bo-Huei Huang, from the University of Sydney in Australia.
Participants were grouped into three levels of physical activity (high, medium or low) and were also given a sleep quality score from 0-5 based on the amount of shut-eye they got, how late they stayed up, insomnia (失眠), snoring and daytime sleepiness.Those with the highest risk of dying from cancer or heart disease during the study period were those with the worst quality sleep and who didn't meet the WHO recommended guidelines for exercise.
A.The findings suggest a likely synergistic (相互的) effect, an interplay, between the two behaviors |
B.That risk went down for people with poor quality sleep but who did meet the exercise guidelines |
C.Exercise can make up for the lack of sleep quality |
D.It's the relationship between them that is interesting in this particular study |
E.However, that risk just about disappeared for those who didn't score well on sleep but did score well on physical activity |
F.This also means that high quality sleep can slow a person's risk of illness |
G.In the case of all forms of cancer |

3 . We all know about the health benefits of swimming. It offers a great workout for the body—it builds muscle strength and cardiovascular (心血管) fitness. If you don ‘t mind getting wet, it can be fun, too.
Cold-water swimming, sometimes called wild swimming, involves swimming in natural areas including ponds, rivers and the sea. Jumping in gives a short sharp shock to the body, but many participants say they have got used to it.
But what is it that people are gaining from this cold experience? Doctors say getting into cold water causes a stress response, but when you do it more, your reaction to stress will be reduced. It’s also thought to have a strong calming effect.
So, if you’re convinced that this is for you, take this advice: approach it with caution, swim with a friend, and maybe start in summer, when the water temperatures are higher!
A.It’s really amazing. |
B.A cold dip might wake you up. |
C.The water temperature is a bit higher. |
D.When did you swim in the river last time? |
E.But who would enjoy swimming in icy water? |
F.Cold-water swimming helps cure certain health problems. |
G.There are bigger benefits to this stress-reducing exercise, though. |
4 . If you think that running marathons will help you live a long and healthy life, new research may come as a shock. According to a recent scientific study, people who do a very strenuous workout are as likely to die as people who do no exercise at all.
Scientists in Denmark have been studying over 1,000 joggers (慢跑者) and non - joggers for 12 years. The death rates from the sample group indicate that people who jog at a proper pace two or three times a week for less than two and a half hours in total are least likely to die. The best speed to jog at was found to be about 5 miles per hour. The research suggests that people who jog more than three times a week or at higher speeds of over 7 mph die at the same rate as non - joggers. The scientists think that this is because strenuous exercise causes structural changes to the heart and arteries(动脉). Over time, this can cause serious effects.
Peter Schnohr, a researcher in Copenhagen, said, “If your goal is to decrease risk of death and improve life expectancy(寿命), jogging a few times a week at a proper pace is a good strategy. Anything more is not just unnecessary, and it may be harmful.”
The implications (暗示) of this are that moderate forms of exercise such as tai chi, yoga and walking may be better for us than “iron man events, triathlons and long - distance running and cycling. According to Jacob Louis Marott, another researcher involved in the study, “You don't actually have to do that much to have a good impact on your health. And perhaps you shouldn’t actually do too much”.

6 . The benefits of exercise have been fully noted and your resolutions have been made. Yes, you want to be fit and live a long and healthy life.
According to standard advice issued by the World Health Organization, adults should be getting at least 150 minutes of moderate physical workout or 75 minutes of vigorous activity per week to extend their lives, get fit, have stronger muscles and be a healthy weight. If that didn’t already sound a lot, the WHO says to double that if you want to get further benefits.
The good news for those who dislike sports is that it’s possible to stick to these guidelines without entering a gym or breaking into a jog.
This idea is in line with evidence from a study last year of more than 130,000 people in 17 countries, which found that walking to work and housework such as vacuuming or mopping the floor are activities enough to reduce the risk of early death by 28 per cent, as long as you do 150 minutes a week. If you aren’t one for housework, you will be pleased to hear that your weekly amount of exercise can be put into the weekend with no ill effects, says Gray Donovan of Loughbirough University, UK.
A.However, take care not to do too much exercise. |
B.Most governments urge people to do a little every day, or at least spread their exercise over the week. |
C.Having a busy weekend with three or four hours spent taking exercise does more good than thought. |
D.Could you ever get too much of a good thing? |
E.But what do you actually have to do to get the desired results? |
F.The WHO’s definition of moderate exercise includes housework and gardening. |
