You finish a workout and feel great. Then you get up the next morning and your exercised muscles feel sore. You find it hard to lift your arms and brush your teeth, or bend down to pick up a book. What has happened?
Scientists call this soreness 24 to 48 hours after your exercise “delayed onset (延迟发作) of muscle soreness”, or DOMS. It is caused by microscopic damage to muscle fibers, which releases chemicals. The chemicals irritate (刺激) nerve fibers and cause pain.
Muscle soreness is a good sign. It means that you have challenged your muscles and are getting stronger. Everyone experiences it, even the best athletes. But it can be avoided by using the right exercise methods. Here are some tips:
* Warm up before you work out. This is helpful to avoid muscle soreness, but more importantly to avoid injury. It starts circulation to the muscles and warms the muscles and tendons, getting them ready for exercise.
* Stretch after your workout. After exercising, make sure you stretch your muscles for 15 to 20 seconds before they cool down. They will be warm and elastic (弹性的) so they will stretch well.
* Don’t do too much too soon. Whether it’s jogging, running, whatever workout routine you are starting, just do half of the exercise volume the first week to introduce your muscles to the exercises.
If you are already feeling muscles soreness, here are some ways to help relieve it.
* Get a massage (按摩). Lightly massage the sore muscle and gradually increase the depth of the massage. It might be painful in the beginning but it will gradually ease the muscle soreness.
* Take a hot bath. Nothing beats a long soak in a hot bath for muscle soreness. The heat will increase circulation and provide a soothing (舒缓) effect.
* Flush your muscles. Run hot (as hot as you can bear) water over the sore muscles for two minutes and then immediately switch to cold water for 30 seconds. Repeat this process five times. This has the effect of opening and closing your blood vessels (血管). It will flush the acid (酸物质) from them and ease the soreness.
* Exercise gently. Go for a slow walk and breathe deeply. This helps reduce muscle soreness by increasing blood flow to the sore muscles.

You get anxious if there’s no wi-fi in the hotel or mobile phone signal up the mountain. You feel upset if your phone is getting low on power and you secretly worry things will go wrong at work if you’re not there. All these can be called “always on” stress caused by smart phone addiction(上瘾).
For some people, smart phones have freed them from the nine-to-five work. Flexible working has given them more autonomy (自主权) in their working lives and enabled them to spend more time with their friends and families. For many others, though, smart phones have become cruel masters in their pockets, never allowing them to turn them off and relax.
Pittsburgh-based developer Kevin Holesh was worried about how much he was ignoring his family and friends in favor of his iPhone. So he developed an app — Moment — to monitor his usage. The app enables users to see how much time they’re spending on the device(设备) and set up warnings if the usage limits are broken. “Moment’s goal is to promote balance in your life,” his website explains. “Some time on your phone, some time off it enjoying your loving family and friends around you.”
Dr. Christine Grant, an occupational psychologist at Coventry University, said, “The effects of this ‘always on’ culture are that your mind is never resting, and you’re not giving your body time to recover, so you’re always stressed. And the more tired and stressed we get, the more mistakes we make. Physical and mental health can suffer.”
And as the number of connected smart phones is increasing, so is the amount of data. This is leading to a sort of decision paralysis (瘫痪) and is creating more stress in the workplace because people have to receive a broader range of data and communications which are often difficult to manage. “It actually makes it more difficult to make decisions and many do less because they’re controlled by it all and feel they can never escape the office,” said Dr. Christine Grant.
1.What’s the first paragraph mainly about?
A. The popularity of smart phones.
B. The progress of modern technology.
C. The signs of “always on” stress.
D. The cause of smart phone addiction.
2.Kevin Holesh developed Moment to_______.
A. research how people use their mobile phones
B. help people control their use of mobile phones
C. make people better use mobile phones
D. increase the fun of using mobile phones
3.What’s Dr. Christine Grant’s attitude towards “always on” culture?
A. Confused. B. Positive.
C. Doubtful. D. Critical.
4.According to the last paragraph, a greater amount of data means_______.
A. we will become less productive
B. we can make a decision more quickly
C. we will be equipped with more knowledge
D. we can work more effectively
