How do you get a good night's sleep?

    You may put your pillow (枕头) at the proper height, drink a glass of hot milk or maybe listen to some light music before bedtime. {#blank#}1{#/blank#}When World Sleeping Day falls on March 21, it will be a good time to explore a long-ignored fact that may make you feel tired after you wake up. Scientists have discovered that the position of your spine (脊椎) is very important when you sleep.

    {#blank#}2{#/blank#}Let's have a look at the advantages and disadvantages of each position.

On your back

    Sleeping on your back is the ideal (理想的) position to be in. First of all, your spine is in the best position.{#blank#}3{#/blank#}The downside is the greater likelihood of snoring (打鼾) and sleep apnea (窒息).

Lying on belly

    {#blank#}4{#/blank#}Dr Vaclav Vojta, a US child development specialist, said this is bad for your back because it takes away the natural curve (曲线) of your lumbar (腰部的) spine. But he also noted that this helps to prevent some snoring and sleep apnea.

On your side

    Sleeping on our sides happened naturally while we were in the womb (子宫).{#blank#}5{#/blank#}Plus, sleeping on your side (the left side in particular) has been reported to reduce troublesome digestive problems like heartburn. The downside is the “dead arm” and finger numbness (麻木) from this position.

A. Lying face down with your legs straight and your arms right by your sides is a bad idea.

B. Sleeping on your side can be a quick fix for snoring and can help to improve breathing.

C. Do you and your friends ever talk about your sleeping position with each other?

D. And a new study suggests that the sleeping position has something to do with it.

E. Of the three sleeping positions, which one do you usually go for?

F. You are also less likely to have digestive (消化的) problems.

G. But one thing you may tend to ignore is sleeping positions.

    Gardening is popular in many parts of the world. This outdoor activity gives us beautiful plants, pleasant smelling flowers and fresh fruits and vegetables. But it also does a lot of good to our health.

    Gardening connects people. When you are gardening, you are outdoors. So it is a perfect chance to meet and spend time with your neighbors. Most people love to talk about their hobbies, and gardeners are no different. They usually enjoy showing people what they are growing. And most enjoy sharing advice and stories about their gardens almost as much as sharing flowers and vegetables from their gardens.

    Gardening is a great activity for children. It gets them outdoors and off computers, televisions and cell phones. Gardening is also a great teacher. It can teach a child about where food comes from and healthy eating. It also helps them to understand that the natural resources (资源) are not inexhaustible and the importance of using them carefully.

    Then, when you garden, you must move around. All the different movements needed for gardening, like bending and lifting, work small muscles (肌肉) in the body. And you can easily get good exercise when you are digging holes or pulling grasses.

    In a study, researches looked at more than 2,800 people over the age of 60. They studied their lifestyle habits, activities and health over a 16-year period. They found that gardening could lower the risk of future dementia (痴呆) by 36%. Gardening requires people do many repeated actions, such as picking off dying flowers. These actions have a calming influence on the brain. The brain is still active but not in the same way when we use computers.

    You'll feel wonderful when what you grow in a garden looks, smells, feels and tastes good.

    The idea that you can use humor, laughter, and play to make you healthier probably seems too simple to be true. However, it is really true and simple. The sense of humor, laughter and play plays an important part in keeping you healthy.

    Treat the blues with a sense of humor, which is closely tied to laughter. Laughter is infectious. Have you ever heard a big laugh of a young child and been able to keep yourself from smiling? When laughter is shared between people, it makes them closer to each other and increases their happiness. Smiling is the beginning of laughter and a smile is also just as infectious as laughter is. You can experience something by smiling at everyone around you, and you will feel happier just by sharing a smile, even with a stranger.

    Play is an important part of making sure that we stay healthy. We are often encouraged to make sure our children play, and are told of the benefits of being out playing. However, what we often forget is that it is just as important for old people to make play be part of their life as it's for children. Physical play is important for the old and it certainly helps prevent illness. While the studies are still in the early stages, the studies that have been done have shown that physical play certainly plays a part in preventing cognitive (认知的) falling.

    A famous doctor once received a little child who was badly ill. Thanks to his skill and care, his young patient got well and was soon able to get up and run about again.

    The child's mother was very much obliged to the doctor, and she called on him to thank him for what he had done for her child. "Doctor," she said, "you have saved my little son. I don't know how to thank you enough. I feel that money alone cannot repay you, so I have made this little purse with my own hands, as a sign of my gratitude. I hope you will accept it." The doctor stood up and said coldly, "Madam, a little present like that is very nice between friends, but a doctor needs to be paid properly for what he has done." The lady was so surprised and hurt so much that she could not reply for a moment. Then she said quietly, "Perhaps you will tell me how much your fee is?"

    "Fifty pounds", he answered.

    The lady opened the little purse and took out four fifty-pound bank notes. She handed one of them to the doctor, and put the other three back into the purse. She put the purse into her handbag and, saying good bye to the doctor, went out of the room.

Below is a list of women who changed the world when they were young girls and teens.
