3 . Waking up with “morning breath” is quite normal, and it usually goes away after eating and drinking, or brushing your teeth. Your breath can also smell different after drinking coffee or alcohol, or eating spicy food, garlic or onions—sometimes you may think you've got bad breath when actually it's quite okay.
However, if you're concerned or embarrassed about halitosis(口臭)—ongoing bad breath, a trip to the doctor or dentist should be in order, because there could be something else going on with your health.
Your mouth is the first place to investigate the origin of bad breath. When smell-causing bacteria attack food after eating, they release strong-smelling sulphur(硫). People with halitosis may have more of these bacteria present in their mouth. Additionally, not cleaning, or brushing your teeth properly leads to a build-up of harmful substances on the teeth, and can cause some swelling and strong smell in the mouth. Medical conditions that reduce the amount of saliva(唾液)in the mouth can cause problems too. That's because saliva keeps the mouth just wet, reducing strong smell.
Strong-smelling breath can be a symptom of medical conditions such as mouth or throat infections. A pear-smelling breath caused by high blood sugar, which occurs as a result of uncontrolled diabetes(糖尿病), can also indicate some other serious diseases.
If you're worried how your breath smells at close range, nutritionist Katrina Pace comes to the rescue with simple tips. "Keep away from sharp-tasting food, drink and alcohol," Katrina said. "Drinking water regularly and chewing fresh parsley(欧芹)can also help."

Faces communicate feelings. They can tell people if we are happy, sad, or confused. Faces have another use, too. Like your unique fingerprint, your face can identity you. Unless you have an identical twin, there is no one else in the world with your face. By matching the code of any new lace to the codes for faces that are already in the database, nowadays facial-recognition technology can probably pick up the same person.
Now, organizations are using your face for many different purposes. Police department uses facial-recognition databases to identify people. For example. The U. S. police analyzed the data from the facial-recognition technology to look for terrorists at a large sports event in Florida. Another use is for preventing identity theft. Banks will use a customer’s “face-print” for identification instead of an ID card, which are easy to steal.
Not everyone is happy with these developments. Many people feel that facial-recognition technology can be an invasion of privacy. For example, advertisers are using the technology to analyze people’s laces. When people walk by an outdoor advertisement, the sign takes their picture. It analyzes the picture and suggests products for these people to buy, such as makeup. People have another concern: A stranger may take your picture without your knowledge, match this photo to one on a social media website, and obtain your personal information such as age, interests, and even address.
Experts hope that we will find ways to limit the risks of the technology. It’s certain that as the new technology develops, we will need new laws to protect people. Meanwhile, experts have a suggestion: Simply tilt your head 15 degrees to the side when someone takes your picture. Facial recognition doesn’t work on faces in this position!

5 . First-Aid to Stop Nosebleeds
Nosebleeds occur when the inner lining of one's nose is hurt or dry. Although a nosebleed maybe frightening, most conditions that cause nosebleeds are not serious or life threatening.
Position your body. To begin, sit down, since it is more comfortable than standing. Tilt head forward so that the blood drains through the nostrils.
Press the nose. Use your thumb and index finger to hold your nostrils for 5 to 10 minutes while you breathe through your mouth. This puts pressure on the part of your nose that's bleeding and can make the blood stop flowing.
Cool yourself down. Lowering your body temperature can help reduce the blood flow to your nose. To do this, place ice cubes in your mouth. This helps achieve a lower temperature sooner than cooling the external part of the nose.
A.Be gentle on your nose. |
B.Wash your nose and rest. |
C.Keep your head above your heart. |

9 . Some experts say muscle loss begins around age 50. But others say it can start as early as age 30. Although muscle loss may be a natural part of aging , you can do some things to slow it down. Lost muscles are not gone forever. It is better to start building muscles when you are younger and in good health. Experts may not know exactly when muscle loss starts , but it is never too late to start strength training.
Simply put , strength training is what makes one's muscles stronger, Let us talk about some of the health benefits of strength training. This information comes from Harvard Medical School and the Mayo Clinic, a nonprofit health and research organization in the United States.
Harvard University researchers say that strength training puts pressure on your bones. This pressure can aggrandize the thickness or density of bones. This can reduce your risk of developing osteoporosis — a disease that weakens bones, making them easy to break, usually when people get older or because they do not have enough calcium or Vitamin D. And experts say strength training can reduce the problems of many long-term disorders, such as back pain, heart disease, diabetes and depression.
Considering it's easy for people to run to fat when getting older, strength training can help you take control of your weight. Muscle weighs more than fat. But muscle increases your metabolism (新陈代谢),and a higher metabolism helps you burn more calories.
Strength training can improve your ability to take activities. For example, having stronger muscles makes it easier to lift and move things. So, your risk of falling or getting injured may be lessened. As we age, this can greatly add to our quality of life. And some research shows that regular strength training, when combined with other kinds of exercise, may help older adults think and learn better.
The aging process affects the human body in many ways. It is believed that strength training can have a major effect on a person's life, so consider motivating others to join you in the many physical and emotional benefits of strength training.

10 . Crossing your legs is an extremely common habit. You may find it comfortable to sit with one knee crossed over the other, but it might be causing health problems that you are not aware of. A study published in Blood Pressure Monitoring stated that sitting with your legs crossed can increase your blood pressure. This happens because the blood in your legs has to work against gravity to be pumped back to your heart, while the crossed legs increase resistance, making the blood even harder to circulate. You won't feel any immediate effects, but don't keep the posture more than 15 minutes. Get up and walk around at least once every hour.
Crossing your legs can also lead to neck and back pain and make your hips in a twisted position, causing one of your pelvic bones to rotate. Since your pelvic bone supports your neck and spine, this can cause pressure on your lower and middle back and neck.
This sitting habit will make your feet and legs get tingly or have the feeling of being asleep, because it causes pressure on the veins and nerves in your legs and feet, leaving numbness and/or temporary paralysis in the legs, ankles, or feet. While the feeling of discomfort may only last a minute or two, repeatedly crossing your legs until they feel numb can cause permanent nerve damage.
So next time you sit down, try to get yourself in the habit of sitting with both of your feet planted flat on the floor to save your health in the long run.
