10 Tips To Healthy Eating And Physical Activity






1. Start Your Day With BreakfastBreakfast fills your "empty tank" to get you going after a long night without food. Eating a good breakfast can help you do better in school. Easy to prepare breakfasts include: cold cereal with fruit and low-fat milk, whole-wheat toast with peanut butter, yogurt with fruit, whole-grain waffles or even last night's pizza.

2. Get Moving
It's easy to fit physical activities into your daily routine. Walk, bike or jog to see your friends. Take a 10 minute activity break every hour while you read, do homework or watch TV. Climb stairs instead of taking an escalator or elevator. Try to do these things for a total of 30 minutes every day.

3. Snack Smart
Snacks are a great way to refuel. Choose snacks from different food groups - a glass of low-fat milk and a few graham crackers, an apple or celery sticks with peanut butter and raisins, or some dry cereal. If you eat smart at other meals, cookies, chips, and candy are okay for occasional snacking.

4. Work up a sweat Vigorous work-outs, when you're breathing hard and sweating, help your heart pump better, give you more energy and help you look and feel your best. Start with a warm-up that stretches your muscles. Include 20 minutes of aerobic activity, such as running, jogging or dancing. Follow-up with activities that help make you stronger such as push-ups or lifting weights. Then cool-down with more stretching and deep breathing.

5. Balance your food choices - don't eat too much of one thingYou don't have to give up foods like hamburgers, french fries, and ice cream to eat healthfully. You just have to be smart about how often and how much of them you eat. Your body needs nutrients like protein, carbohydrates, fat, and many different vitamins and minerals such as vitamins C and A, iron, and calcium from a variety of foods.

6. Get fit with friends or family Being active is much more fun with friends or family. Encourage others to join you and plan one special physical activity event, like a bike ride or hiking, with a group each week.

7. Eat more grains, fruits, and vegetables These foods give you carbohydrates for energy, plus vitamins, minerals, and fibre. Besides, they taste good! Try breads such as whole-wheat, bagels, and pita. Spaghetti and oatmeal are also in the grain group.

8. Join in physical activities at school Whether you take a physical education class or do other physical activities at school, such as intramural sports, structured activities are a sure way to feel good, look good and stay physically fit.

9. Foods aren't good or badA healthy eating style is like a puzzle with many parts. Each part, or food, is different. Some foods may have more fat, sugar or salt, while others may have more vitamins or fibre. There is a place for all these foods. What makes a diet good or bad is how foods fit together. Balancing your choices is important. Fit in a higher-fat food, like pepperoni pizza, at dinner by choosing lower-fat foods at other meals. And don't forget about moderation. If two pieces of pizza fill you up, don't eat a third.

10. Make healthy eating and physical activities fun!

Take advantage of physical activities you and your friends enjoy doing together and eat the foods you like. Be adventurous - try new sports, games, and other activities as well as new foods. You'll grow stronger, play longer, and look and feel better! Set realistic goals - don't try changing too much at once.

Prehistoric and Primitive Medicine


Prehistoric and Primitive Medicine
Archaeologists and anthropologists who study prehistoric man and primitive tribes tell us human societies have always had special individuals, both men and women, who took the job of healer and were responsible for preventing illness and curing the sick and injured. These shaman almost always held multiple roles as healers, magicians, rulers, or priests.

Primitive medicine men learned how to splint, but probably not set, bone fractures. They also frequently performed a type of brain surgery that we today call trephination. Trephination was done by using stone instruments to bore or grind holes in the skull. Researchers do not know if the procedure was done to relieve demon spirits, treat skull fractures, or remove bone splinters. It is possible that trephination was done at different times for all of these reasons.

In addition to magic, spells, prayers, and charms, shaman and healers often used signature, or symbolic, items to treat their patients. These signature treatments included things like drinking the blood of a warrior to increase strength or eating leaves shaped like body organs to cure a disease. Sometimes, through chance, these signatures worked. When they did, the medicine men, or shamans, would pass the information to the next generation of priests. Digitalis, morphine, quinine, and ephedrine are all modern medicines that have been passed down to us from prehistoric signature practice.

egyptian medicine history


Egyptian Medicine
Western medical tradition can be traced back directly to the practitioners of ancient Egypt. The most famous of the Egyptian physicians was Imhotep, who lived about 2800 BC. Imhotep is also famous as the architect of the great Step Pyramid of Saqqarah. Egyptian priest-physicians specialized in treating different parts of the body, because they believed different parts of the body were governed by different gods. They used special religious incantations to treat patents for specific ailments.

Egyptologists have found two large medical documents, written on papyrus, that tell much about medical practice.
Just as with prehistoric civilization, healing and religion went hand-in-hand, but Egyptian priest-physicians kept careful case histories. They developed surgical techniques that are still used today including using direct compression to stop bleeding. Most interesting, the Egyptian texts record methods of training and practice that closely resemble modern medicine. These documents define a variety of diseases and conditions, identify their symptoms, explain what other healers should look for during examinations, suggest specific therapies, and describe how to develop a prognosis.

The priest-physicians were assisted by other lay physicians and magicians who specialized in bandaging and public health. There was an official "Lady Director of Lady Physicians" who supervised the work of the female practitioners who specialized in minor surgery and bloodletting as well as obstetrics and gynecology.

Egyptian pharmacists used almost 700 different drugs and an assortment of mortars, mills, sieves, and balances to prepare over 800 standardized prescriptions that were dispensed to patients as pills, ointments, inhalants, and gargles. Some historians think that the modern day Rx pharmacy symbol has its origin in the Egyptian Eye of Horus.
