1 . Spending time outdoors has long been linked (联系) to better health. Gardening goes beyond just beautifying outdoor spaces—it can have a deep effect on our physical and mental (身心上的) health.

Gardening involves physical activity that works all the main muscle (肌肉) groups, which is helpful for overall health. “Activities such as digging, planting, weeding and harvesting require movement and can help to improve strength,” said Clayton, CEO of an online lawn care company. “Performing these activities regularly can help burn calories, and keep a healthy weight.”

Beyond burning calories and building muscle, lots of studies have shown that gardening can improve the immune system (免疫系统). The Centers for Disease Control and Prevention (CDC) recommends that people get at least 150 minutes of exercise each week, and gardening is listed as a suitable activity. Doing garden work for that time each week can reduce the risk of obesity, high blood pressure and heart disease. Additionally, spending time outdoors makes us get close to natural sunlight, which is important for vitamin D synth.

Gardening provides a chance for social connection, too. It can be a shared activity among family members, friends or neighbors, building relationships and a sense of belonging.

Gardening also offers cognitive (认知的) benefits. It excites the senses, improves focus and encourages problem-solving and creativity. It provides a chance to learn about plants, ecosystems and the environment, developing a deeper understanding and appreciation for nature.

2 . Scientists recently discovered that our brains may be just as busy at night as they are during the day. While we sleep, our brains are doing much more than getting ready for the next day. Scientists found that the brain may be busy cleaning out harmful waste materials.

As with many studies, scientists turned to mice for help. They studied the mice brains as they slept and when they were awake. They saw that the brains of sleeping mice were hard at work.

Dr. Maiken led the study. The brain expert says our brains perform two very different jobs. It seems they have daytime jobs. Later they “moonlight” at a nighttime job. And this study says that is what our brains seem to be doing. “When we are awake, the brain cells are working very hard at processing all the information around us. When we are asleep, they work very, very hard at removing all the waste that builds up when we are awake.” The scientists say that the waste material includes poisons.

They also found that during sleep, the brain’s cells become smaller, which allows waste to be removed more successfully. Dr. Maiken says these poisons end up in the liver(肝脏). There, they are broken down and then removed from the body. “So we need to sleep because we have a cleaning system that removes many of the poisonous waste products from the brain.”

Dr. Maiken says the next step is to look for the process in human brains. She says the results show how important sleep is to health and fighting disease. The research may also one day lead to treatments to prevent or help fight mental disorders(精神疾病).
