Help you burn more fat. How? Cold temperatures may change unwanted tat into a different kind of fat that actually bums calories. The fat in your body isn’t equal. There's white fat and brown fat in our body.     2     Brown fat is metabolic tissue that burns calories. Exercising in cold temperatures turns our white fat to brown fat.

Prevent winter weight gain. Getting yourself to the gym is a challenge during the 'winter months, and a treadmill at home can get boring, which is why we love running in cold weather.     3     We tend to move less and eat more in the colder months. Running bums significant calories and is therefore a powerful tool in maintaining and even losing during winter.

    4     Our bodies are programmed to preserve our fat stores in the winter, slowing down our metabolisms in response to our decreased exercise levels. Running in the cold serves to 'trick' the body, preventing this seasonal slowdown of metabolism (新陈代谢) and helping to maintain a healthy weight.

Stop you from feeling quite so depressed. When the days get shorter and the temperature drops, many people suffer from seasonal depression. Running helps release powerful hormones (荷尔蒙) that help increase positive mood states during the cold weather months.     5     One study found that people who exercised outdoors reported increased energy and decreased feelings of depression.

The game, where players walk rather than run, is designed to help aged people get fit or maintain an active lifestyle no matter what their age and fitness. According to a 2019 survey, there were 1,200 registered clubs and an estimated 40,000 regular participants.

North Ferriby Walking Football Club in East Yorkshire is one such example. “We started in 2015,” explains Mark Leighton, the team’s manager. “The first week we started off, we probably only had four or five players. Now we have 42 registered players taking part over three separate sessions each week.” Mark’s immediate goal is to get the club to 50 registered players across four sessions a week.

Andy Fairburn is a regular at the sessions. Now in his early-seventies, Andy finds the game still has plenty to offer him. “I’ve been playing football since 16. Getting older, your knees start to hurt, and I’ll know when it’s time to stop. I am sill competitive, though, and old habits die hard.”

It goes beyond kicking a football around for players like Andy. “There’s a serious football side if you want to win and a friendship side. I’d rather stick to the latter. It’s brilliant to socialize with people through walking football.”

Walking football is clearly a success story with much to be proud of. However, it’s striking that 87 per cent of clubs reported that less than 10 per cent of players are female. And not all clubs are as fortunate as North Ferriby Walking Football Club, which operates on a pay-as-you-go model and has secure sponsorship to reduce the cost burden.

【推荐3】Once called “the bridge that couldn’t be built,” today it is one the seven wonders of the modern world. This magnificent span, perhaps San Francisco’s most famous landmark, opened in 1937 after a four-year struggle against non-stop winds, fog, rock and treacherous tides.

The world-famous Golden Gate Bridge is easily recognized by its International Orange color. The bridge was built at a cost of $35 million in principal and $39 million in interest and 11 workers’ lives. The bridge, with its twin towers reaching skyward 746 feet, was once taller than any building in San Francisco. It took more than 10 years to make a plan due to powerful opposition, but only four years in actual construction, the Golden Gate Bridge brought the communities of San Francisco and Marin counties closer together.

Pedestrians (行人) including wheelchair users and bicyclists can go on the sidewalks of the bridge during daylight hours but skateboards and roller skates are not permitted.

If you can’t visit the bridge in person, do the virtual bridge walk and don’t forget to check out the view from the top of the south tower.

If interested in biking across the bridge, the Presidio offers bike rentals and electric bike share opportunities, plus a recommended bike path through Crissy Field. For more information, visit the Presidio online.

If you are planning to stay in San Francisco, there are plenty of hotels nearby or with views of the Golden Gate Bridge.

The unusually hot water affected animals that live off the coast of Maine, which are important to the local fishing economy (经济). What’s more, it quickly became clear that the state wasn’t alone. “Heat wave events have popped up all over the ocean.” says Andrew Pershing, scientific officer at the Gulf of Maine Research Institute. “We’ve actually had three huge heat waves in the Gulf of Maine—2012, 2016 and 2018—and now we’re looking at repeat heat waves in the northern Pacific; Australia’s also had some repeat heat waves.”

That’s a big deal for coastal communities whose economies depend on fish and other seafood. Heat waves in recent years drove a lot of changes in life off the coast of the Pacific Northwest, which in turn led to disastrous seasons for fishermen. Unusually hot water supported the growth of algae that polluted the Dungeness crab (螃蟹) fishery on the West Coast, shutting it down for months. At the same time, the hot water off the coast led to continuous dry weather on land, which killed large numbers of salmon (鲑鱼) and raised the risk of wildfires.

The report suggests actions to slow ocean warming and rising and to adapt to its influences. Most importantly, the authors support what has been known for many years: Greenhouse gas emissions (排放物) are the main driver of changes in the world’s oceans, and the global economy must make a complete change to reduce those emissions.

“Even if we cut carbon emissions right now, we are still looking at 20 to 30 years of change.” Pershing explains. “That means, no matter what we do, we have to work out how we are going to adapt to these changes.”

【推荐2】In Spain, children and their families are riding bikes to school together in large groups. The program is called “bicibús” or bike bus. In Barcelona, the program started recently with only five children and grew quickly to hundreds of riders.

The Eixample bike bus begins around 8:25 every Friday morning. The path it will follow is always posted ahead of time, so everyone knows where to join. The bicibús starts off with just a few students and parents, with more and more joining as it travels along.

Most kids ride their bikes, but others ride motor bikes or use skates. Instead of riding in bike lanes (车道) or on sidewalks, the bicibús takes over the entire street. With music playing and bike bells ringing, the bicibús feels like a party.

Being able to ride with a crowd of kids is a big part of the fun. Nine-year-old Maria Pitarch says, “The best part of the bicibús is that we ride along and pick up my friends and we ride together. ”

The Eixample bicibús goes to several schools. When students reach their school, they leave the bus and park their bikes. Some parents have made the bicibús the way they get to work on Friday.

It was possible to bike to school in Eixample before, but it wasn’t really safe for kids. There are a few bike lanes, but there are also lots of cars.

Because one of the main roads used by the Eixample bicibús is busy, having about 20,000 cars and motorcycles every day, the local police are helping stop traffic by riding in front of the bicibús and behind it.

Parents are hoping that the bicibús will help change ideas about how people can get around in the city. They want the city to create wider, kid-friendly bike lanes that are separate from car traffic. They point out that the bicibús also helps cut down on pollution.

Already some other areas in Barcelona are also organizing bike buses. Some bike buses have even been organized in other countries.

【推荐3】In the digital age, we are becoming accustomed to technological innovations, and the fact that they can have a deep impact on our lives.

The number of the smartphone adult users has reached 85 percent in the UK population. Meanwhile streaming and 5G tech are changing the way we watch movies, TV shows and sports events. But Artificial Intelligence(AI) is probably the biggest game-changer of them all. The biggest impacts have nothing to do with robots or even digital assistants like Google Home. Here are two real-world applications of AI that are already changing our world for the better

One is better medical diagnose. If you had some illness, would you want to be diagnosed by a doctor or a machine? You’d probably say the former, but in reality, the question is not that simple. Today, human expertise and AI work side by side to make faster, better diagnoses. Think of it this way—a doctor can spend an hour reading six or seven cases while AI can do six or seven thousand in seconds and then present the doctor with a range of possible medical conditions along with their related probabilities.

The other is reducing fraud( 欺 诈 ) . Fraud against big businesses seems nothing to do with us. In fact, it often ends up affecting us all, especially when insurance companies, for example, are forced to increase the premium( 保 费 ) to cover losses. AI is being used more and more in insurtech, both to speed up the claim( 索 赔 ) process and to mark possibly fraudulent claims more reliably. It does this by analysing big data trends. Faster processing and reduced fraud are good news for everyone, and that can save money for us.
