Are you the kind of person who always keeps a bar of chocolate nearby? Perhaps you feel weak or sleepy without your sweets. If so, you may have a problem that millions of others have: sugar addiction.

Addiction means using a substance or doing an activity over and over again, in spite of its bad effects. Playing computer games, drinking, and eating arc examples of activities that can develop into addictions.

There are four stages (阶段) of behavior that happen during a sugar addiction. Stage one begins with a strong wish for something sweet. This happens because sugar causes the body to produce dopamine (多巴胺). It is a chemical that creates feelings of happiness. In stage two, even after sugar has been eaten, the desire remains and grows. This is because the body becomes less sensitive (敏感) to the effect of sugar over time. So, it is necessary to eat more sugar to produce the positive emotions. In stage three, when a sugar need is not satisfied, the person feels bad. Sugar addicts experience bad emotional symptoms (症状). They also feel physical symptoms, such as headaches, sleepiness, and lack of energy. Over time, a sugar addiction will reach stage four. This is when the worst health effects of sugar addiction can be seen. Unhealthy body weight and depression are examples.

Breaking a sugar addiction can be challenging, but it is important for your health. There are a few things to keep in mind. It’s simple advice you probably have heard before. Eat three meals a day, get enough sleep, and exercise often. Choose healthy sweets, like fruit, and avoid salty snacks. These usually cause people to want to eat sweets. Don’t push yourself too hard. Remember that lifestyle changes happen slowly.

If you’re walking through Boston during a downpour, you might see a poem appear before your eyes. For nearly a year, Bostonians wandering the city streets in the rain may have come across poems on the sidewalks.

Titled “Raining Poetry”, this art installation is a collaboration, which resulted from joint efforts from the nonprofit Mass Poetry and the city of Boston. The first poems were installed to honour the start of National Poetry Month. Several more have been added since then. The poems are invisible during dry and sunny weather, but they appear like magic once raindrops start falling from the sky.

“We want to bring poetry to the people,” said Sara Siegel, program director of Mass Poetry. The poems were selected by Danielle Legros Georges, Boston’s poet laureate. They include written works by artists like Langston Hughes, Gary Duehr, Barbara Helfgott Hyett and Elizabeth McKim. Georges selected the poems mainly based on their relationship to Boston. Another factor was their general themes of water and rain.

The poems were installed by members of the Mayor’s Mural Crew, an organization that introduces young artists to the process of creating public art. Mayor’s Mural Crew uses a biodegradable spray and simple cardboard stencils. The poems can be fixed to the sidewalks within minutes in this way. They will wear away in six to eight weeks. However, don’t worry, the city of Boston and Mass Poetry plan on carpeting city sidewalks with more poems. “It’s a public art project, as the poems are and will be installed in public sites in Boston, and are meant for everyone,” Georges said. “I think this is a wonderful way to bring poetry to the people.”

The poems appear throughout the city. While all of the poems currently installed are written in English, Siegel hopes to add new ones in many languages. “Our hope is that in the next two years everyone in the state will encounter a poem in their daily lives at least once or twice a month,” Siegel said. “This is a fun and unusual way to do that.”

There are many reasons to be excited for colder temperatures as we head into autumn: sweater weather, colorful leaves, drinking coffee without breaking a sweat.

And while we’ve got a personal preference for cold, there are also many scientific reasons that cold is better than hot. And it’s not just about whether you prefer the winter or summer Olympics—it’s about what effects cold temps have on your body. Dive below for the details.

Professor Patrick Baylis recently completed a heat study where he found that a high of 90degrees Fahrenheit(华氏温度计的)makes an average person’s happiness drop in the same way it does between a Sunday and Monday. For many of those who work Monday to Friday, you don’t need research to tell you the Sunday Scaries are real.

Sleep is extremely important for our physical and mental health, and the most suitable temperature is part of getting a good night’s sleep. Dr. Christopher Winter, a neurologist and sleep specialist, states that between 60 and 67 degrees Fahrenheit is the ideal temperature when you’re catching zzz’s. In addition, Dr. Winter recounts that studies have also found that cooler body temperatures lead to more deep sleep. Those who sleep in cooler temperatures also sleep longer and feel more awake the next morning.

When your body shivers, it has to work harder to maintain your body temperature. According to Nancy Clark, shivering can burn 400 calories per hour. When it’s that cold, you expend more energy than in warm weather, though how much depends on factors like the exact temperature and your clothing. Some studies have also found that physical performance drops in hotter temperatures. For example in one study, marathon runners slowed as temperatures increased.

Many of us have a very definite preference between cold and hot, but some research has found that cold has more benefits. Autumn is on its way. Take action for cold temperature.
