1 . It can be incredibly difficult to encourage ourselves to go for a run during winter, particularly when it’s wet and windy outside. But new research has found that even a super-quick run could have great health benefits. In fact, it seems that just a 10-minute session will not only make us feel better, but could actually improve brain health, too. Now, we all know that exercise can improve mental and physical health in many ways.
But when it comes to mental well-being, there’s been relatively little research done on the specific benefits of running, compared with other physical activities, such as cycling. So this was something put to the test during a recent study. Researchers from University of Tsukuba in Japan asked participants (参加者) to run on a treadmill (跑步机) for just 10 minutes. They then had to take a Stroop Color and Word Test which is used to measure reaction time in brain processing. Results showed there was a highest point in self-reported pleasure and an increase in degree of activity of the brain.
In other words, runners were found to have an increase in blood flow in the part of the brain that’s associated with dealing with functions and controlling mood (情绪). Researchers then compared these results to a similar study on cycling, which also showed improved cognition (认知), but no mood improvement. Therefore, it seems various types of exercise can make us feel differently.
The authors noted, “Given exercise is medicine, the effects of drugs differ depending on the type of drug, and different types of exercise such as running and cycling should be observed to have different effects on mental health and brain functions as well.”
So pushing ourselves to get outside for a run really will make us feel better, probably more than other fitness activities. And these findings show that we don’t necessarily need to do a lot of exercise to feel the benefit of it.

3 . Sports can help you keep fit and get in touch with nature. However, whether you are on the mountains, in the waves, or on the grassland, you should be aware that your sport of choice might have great influence on the environment.
Some sports are resource-hungry. Golf, as you may know, eats up not only large areas of countryside, but also tons of water. Besides, all sorts of chemicals and huge amounts of energy are used to keep its courses （球场） in good condition. This causes major environmental effects. For example, in the dry regions of Portugal and Spain, golf is often held responsible for serious water shortage in some local areas.
There are many environment-friendly sports. Power walking is one of them that you could take up today. You don’t need any special equipment except a good pair of shoes; and you don’t have to worry about resources and your purse. Simple and free, power walking can also keep you fit. If you walk regularly, it will be good for your heart and bones. Experts say that 20 minutes of power walking daily can make you feel less anxious, sleep well and have better weight control.
Whatever sport you take up, you can make it greener by using environment-friendly equipment and buying products made from recycled materials. But the final goal should be “green gyms”. They are better replacements for traditional health clubs and modern sports centers. Members of green gyms play sports outdoors, in the countryside or other open spaces. There is no special requirement for you to start your membership. And best of all, it’s free.
