If you've been diagnosed with high blood pressure, you might be worried about taking medication to bring your numbers down. Chronic（慢性的） stress may contribute to high blood pressure. More research is needed to determine the effects of chronic stress on blood pressure. Occasional stress also can contribute to high blood pressure if you react to stress by eating unhealthy food, drinking alcohol or smoking.

    Take some time to think about what causes you to feel stressed, such as work, family, finances or illness. Once you know what's causing your stress, consider how you can rid or reduce stress. If you can't rid all of your stressors, you can at least handle them in a healthier way. Try to:

    Change your expectations. For example, plan your day and focus on your strengths. Avoid trying to do too much and learn to say no. Understand there are some things you can't change or control, but you can focus on how you react to them.

    Focus on issues you can control and make plans to solve them. If you are having an issue at work, try talking to your manager. If you are having a conflict with your kids or spouse, take steps to resolve it.

    Avoid stress triggers（诱因）. Try to avoid triggers when you can. For example, if rush-hour traffic on the way to work causes stress, try leaving earlier in the morning, or take public transportation. Avoid people who cause you stress if possible.

    Make time to relax and to do activities you enjoy. Take time each day to sit quietly and breathe deeply. Make time for enjoyable activities or hobbies in your schedule, such as taking a walk, cooking or volunteering.

    Practice gratitude. Expressing gratitude to others can help reduce your stress.

    If you successfully control your blood pressure with reducing stress, you might avoid, delay or reduce the need for medication.

    It's carnival season in Europe, a crazy time for parades, mask, music and dance. No one is sure where the tradition exactly comes from. But while its origin remains a mystery, this does not keep people from joining it.

    The Carnival of Binche, the most famous one that is staged in Belgium, has been announced as a masterpiece (杰作) of the Intangible Heritage of Humanity by UNESCO. The event usually takes place during a Sunday, Monday, and Tuesday, with performers known as "Gilles" dressed in clown-like costumes, dancing and marching along the streets. During parade, the Gilles throw oranges to the crowd as an act of well-washing and it is considered rude to throw them back.

    Venice is said to be the birthplace of carnivals. In the city, the annual carnival starts 58 days before Easter. It features various brightly-colored and well-made masks. Every year, thousands of visitors go to the city to be part of the festive event.

    The Germans, always considered serious-minded, also have their carnivals. The Cologne Carnival is one of the largest, with Rose Monday as the best part. On Rose Monday Parade, lots of gifts are prepared for the people who join it. For this year, 300 tons of candies and more than 300,000 souvenirs were thrown out of the various nicely-decorated floats (花车) to the crowd.

    The Nice Carnival in the southern French city of Nice lasts two or three weeks from February to march every year. It features floats, music, dance, performances and entertainment activities. The parade of lights and the final day carnival parade are the most exciting parts of the entire event. Compared to the Rio Carnival in Brazil and the Winter Carnival in Quebec, Canada, the Nice Carnival has a special artistic touch, and it is one of the three major carnivals around the world.

    Carnivals were first organized in the Middle Ages. They were supposed to be a time of eating and drinking before the Easter fast (斋戒). Nowadays, they have turned into winter tourism attractions of many European cities.

    Philadelphia offers a ton of attractions that are suitable for people of every age and here are some family—friendly attractions.

    Spruce Street Harbor Park

    Spruce Street Harbor Park, one of the best urban beaches in American, is an outdoor heaven on the Delaware River waterfront. Visitors can relax in a hammock, play on the playgrounds, and play games like table tennis and giant chess. Don't miss out on the park at night, when colorful LED lights hanging from treetops make the entire area bright.

    Blue Cross RiverRink

    Offering ice skating in the winter and roller skating in the summer, Blue Cross RiverRink creates a fun，outdoor experience for the whole family. Visitors can play on the nine-hole mini-golf course during the summer, and enjoy eats and drinks from the on-site (现场的) bar and restaurant all year round.

    Sesame Place

    Big Bird, Elmo and the other stars of Sesame Street come out and play at Sesame Place, the only theme park in the nation starring the popular TV show's most lovable characters. A water park, interactive activities，parades, fireworks and shows add to the fun.

    Once Upon a Nation Storytelling Benches

    On summer days, uniformed and professional storytellers at 13 storytelling benches throughout Philadelphia's Historic District entertain visitors with true, free, three-to-five minute tales about the colonial (殖民的）era as part of Once Upon a Nation . Children can pick up a Story Flag at any storytelling bench, and then collect a star from every storyteller on their journeys. Flags with all the stars can get free rides on the Parx Liberty Carousel at Franklin Square.

    Andrew Jackson has been sitting pretty on the $20 bill for 87 years. Is it time to bring some new blood to the banknote?

    The non-profit organization called Women on 20s is campaigning to put a woman's face on American money. Barbara Ortiz Howard, the company's founder, would like to see a woman on the $20 bill by 2020.That year marks the 100-year anniversary of the 19th Amendment to the United States Constitution, which gave women the right to vote.

    Howard got the idea when she realized that her daughter had no everyday reminders of famous women in history. She asked her friend Susan Ades Stone, a journalist, to join her cause. “Part of the aim is to educate as many people as possible about as many women as possible,” Ades says. “We want to see how many people we can reach.”

    American money values the successes of former presidents and founding fathers. Currently, there are only two women on money: Susan B. Anthony is the face of the rare dollar coin, and Sacagawea can be seen on the gold dollar coin. There are no women on paper bills.

    With help from writers and historians, Howard and Stone came up with a voting list featuring 15 important women. Ades says there is a standard for choosing candidates. They look at the women's contributions to our world, and at what challenges they faced.

    More than 72,000 people have voted so far in the poll. Ades says the competition has narrowed to a “very close race”, but won't say who's in the lead. After two rounds of voting, Women on 20s will send their campaign to the White House for consideration. The final decision is up to the Treasury Secretary, Jack Lew. Lew is unlikely to make a change without the president's approval. But last year, when a little girl asked the president why there aren't any women on US currency, he said that adding a woman is a “pretty good idea”.

    In my memory, winters always used to be really unpleasant. You had to bundle up just to keep warm when you went outside. You were often cold, wet, slip on the ice, and you'd arrive home to an ice-cold house. And that would mean turning on the heating and waiting. It's a miracle you didn't get cold to the bone.

    Fortunately, things don't have to be so challenging any more. Technology, engine ring and design have advanced giving us new solutions to old problems. It means dealing with winter needn't be like skating on thin ice.

    With a smart thermostat (温度自动调节器), our homes can be warm when we need them to be. Many models feature smartphone apps that allow you to control temperature remotely, so we can warm up the house before we arrive home. According to techradar.com, Tado's model features voice control, while the Nest 'leans' your habits and automatically heats the home for you.

    Clothes have been given an upgrade, too. Electronic thermal jackets, sweaters and coats heat up when you turn them on. What better way to keep warm in the dead of winter? At the touch of a button, or through an app on our phones, the clothing generates heat from elements placed inside. Many models offer three levels of heating which stay warm for over 12 hours. .

    Finally, there is the clothing for the head, beanie s and Earmuff, that feature speakers included in the fabric using Bluetooth technology so we can listen to our favourite music or, in some cases, have a phone callusing the in-built microphone. All while keeping the head warm and avoiding a cold.

    For many, the thought of winter used to be enough to make their blood run cold. But using technology, life needn't freeze up. With the right solutions, there's no reason why winter can't be really, really cool.
