Flu (which is short for influenza) is a highly infectious disease, the cause of which is a very tiny organism known as a virus. Several types of flu are recognized, depending on the type of virus that causes the disease.

Flu can often cause problems in breathing, and general infection of the lung. With elderly and weak people, these added complications often produce serious results. The virus, if not properly treated, can weaken the body so that patient may develop more serious illnesses, such as pneumonia and bronchitis. When people catch flu, they often complain of a headache or a sore throat. They usually have a fever and their temperature rises from the normal 37℃ (98.6) to about 39.5℃ (103). Sometimes a person has a dry hacking cough and aching joints.

Today many doctors use drugs that fight the disease. And scientists have also developed vaccines that help to prevent it. If the patient has proper treatment, and complete rest in bed, the virus is normally beaten within a week to ten days.

How does flu spread so quickly? When the infected person breathes out, sneezes or coughs, he gives out droplets of moisture in the breath from his mouth or nose. These remain in the air for some time. Flu viruses are present in these droplets. If a person sneezes in a crowd or poorly ventilated place, such as a lift, viruses can easily be carried from an infected person to a healthy person. This is known as droplet infection. The healthy person will breathe in the viruses given out by the infected person.

There are three main types of virus that cause flu, which are called type A, B and C. type A is the most powerful of the three, and undergoes minor changes in its genetic material every few years. The new form of the virus is called a strain. The new strain is not affected by the current vaccines. It is said to be “resistant” to them. So doctors must be continually producing new vaccines to combat the new strains of virus.

For most of us, the purpose of the holidays is to bring peace, love, and goodwill towards all. Yet, for many, the holiday season often means stress, fatigue, pressure, disappointment and loneliness.

These feelings, often known as the “holiday blues”, may be even more prevalent, due to the emotional turmoil (波折) of the past few months, not to mention the unsteady economy. Experts say even the more ritual tasks of shopping, decorating, late-night parties, cooking, planning and family reunions can be holiday stressors. In addition, the psychological phenomenon known as seasonal affective disorder, or SAD, may bring a specific type of depression related to winter’s shorter days and longer nights.

“Certainly just because it’s the holidays doesn’t mean people are going to be happy,” says Dr. Doug Jacobs of Harvard University. “And this will be a particularly hard holiday for some who are dealing with a lost job, debt, or even a lost loved one.”

And with family reunions becoming less frequent events over the years, there is now the added pressure of getting just one chance to get it all right. “Families are much more different now. The disappointment and sense of alienation that often results from family gatherings, is actually a realization that the fantasy is not met.” says John Stutesman, a clinical psychologist at Northwestern Memorial Hospital in Chicago.

Still, say experts, the blues should be addressed. The most essential step, says Stutesman, is for the individual to acknowledge their feelings and the reason for their withdrawal. “Denial will only compound the stress they’re feeling.” Stutesman recommends people do things that are normally comforting in order to get a handle on the holiday stress. “If they’re feeling a little blue, they should try to do things personally satisfying for them. Maybe this is exercise, cooking, reading a book, or massage.” Stutesman also advises that sometimes “avoidance is actually not such a bad idea.” In some situations, fulfilling social obligations may be self-destructive when the best thing may be to just stay home. The healthy choice has to do with taking care of oneself.”

Winter is a great time to experiment with new sports. The key is to find one that matches your interests and natural abilities. If you like to walk, keep walking ― on snowshoes. If you want to try an endurance sport, go for cross-country skiing. Besides, snowboarding is just great fun.

Not satisfied with these? Try downhill skiing, then. Downhill skiing is not as hard as it used to be ― shorter, lightweight, curved skis make any beginner feel like an Olympic winner. These newer skis ― along with another type of equipment called skiboards, which are even shorter than skis ― help you control your speed and body movements.

Consider testing the latest high-tech skis or snowboards?Check with your local sports shops or the rental places at the ski mountains about sample programs.

You could also try sledding. Use a wood-framed sled with steel runners or a plastic sled to head down a snowy hill. If you prefer ice to snow, think hockey or figure skating.

Runners can also train during the winter in spite of wet or slippery roads. One of the easiest sports around, snowshoeing can be excellent cold-weather cross-training for runners and cyclists ― or anyone wanting to take a wintry walk in the woods. Snowshoes are smaller, lighter, and better than ever. If you want to try them out, you may be able to rent a pair for a day at many of the larger outdoor or sporting goods stores.

Whatever sport you choose, don’t rely on a friend for instruction. You wouldn’t let an inexperienced doctor perform a brain operation on you, but why let one teach you to ski or skate? That’s what instructors are for ― to help newcomers start out right. Instructors can give you advice about equipment, techniques, safety, and dealing with injuries if they do happen to you.

Above all, if you want to progress, invest your time in learning the basic skills thoroughly. Everything else you do as a skier, boarder, or skater will be built on these first skills.
