Neil B. Kavey, MD, Director, Sleep Disorders Center, New York Presby- terian Hospital | The sleep specialist. Try behavior changes and proper use of medication. At night, keep away from bright light. In the morning, open the shades and go out for a walk, to tell your brain, "This is, the beginning of the day." You can try OTC sleep aids, but if you suffer for more than three weeks, see a doctor. Drugs are safe when used properly, and better than the consequences of not sleeping. |

Stress often plays a role in insomnia, so try to change your reaction to it. Don"t exercise or eat at the end of the day, and avoid or limit caffeine, alcohol and nicotine.

And remember, people who eat a healthy diet of whole grains, fruits and vege-tables, and low-fat protein feel better and sleep better. |
Sandra McLanah- an, MD, Medical Director, Integral Health Center, Buckingham, Virginia | The mind/body pro. Lying in bed, starting from your legs and moving up to your head, tense your muscles one at a time, then release. Your body will feel more relaxed, like a rubber band after it"s been stretched.

| Hiking is not only one of the best forms of physical exercise, but it is also one of the best forms of mental relaxation. It is good for all ages and especially good as a family and group activity. Since there are so many different kinds of hiking, it is not possible to give any general rules to follow. Short and frequent hikes, needing no planning or special equipment, are enjoyed by most people. * Keep in shape by walking at a fast pace for at least 15 minutes every day. Climbing stairs instead of using a lift and running not too far is also a good way of keeping in shape. * On any hike nothing is more important than good, comfortable shoes. * The things you take might include matches in a waterproof box, a knife, compass, map, first aid items and flashlight. * Cameras may be taken, but don"t load with too much. * On longer hikes keep a comfortable, steady pace and take rest stops often. * Drink only safe water. If in doubt, boil the water. * Don"t go along the busy roads. When you have to use a road, keep as far over on the left as possible. * Leave word at home or some other places as to where you are going and when you plan to return. * On almost any hike, a map is a good idea. If going into a strange place, a detailed map is most helpful. * Take along a field guide on flowers, birds, rocks, or other subjects depending upon your interests. This can add greatly to the enjoyment and educational value of your hike. | |

| About 97% of the world"s water is salty and is found in our oceans and seas. But, as we can"t drink seawater, how can it be important? Every part of our seas and oceans contains an amazing number of animals and fish that live at different ocean depths. Most of the different species of animals and fish depend on simple plants for their food. These simple plants called algae (海藻) drift near the surface of the ocean and use sunlight to turn carbon dioxide and water into food and oxygen. In fact, algae produce over half of the oxygen people breathe. How important seawater is! Each plant or animal in our seas and oceans is an important link in a food chain. The algae are eaten in large amounts by microscopic animals, which are in turn consumed by larger animals. These food chains are delicately balanced. The bad news about the food chains in the oceans is that they are under threat because of man. People once thought that the oceans were so big that it didn"t matter if we dumped rubbish into them or caught huge quantities of fish and whales for food. But we now know this is not true and fish stocks in the oceans have started to drop. Thankfully, the world is taking steps to protect the future of our oceans by introducing international agreements to protect marine habitats (海域). Most countries have introduced fishing restrictions (限制) to protect fish stocks in the oceans and new techniques are being pioneered to deal with pollution. Finally, the importance of protecting oceans is being made known to more people. This is just the beginning of a long process to protect the oceans for our future. We depend on the oceans for fish which are an important part of the human diet. How important seawater is! | |
