Gardening is popular in many parts of the world. This outdoor activity gives us beautiful plants, pleasant smelling flowers and fresh fruits and vegetables. But it also does a lot of good to our health.
Gardening connects people. When you are gardening, you are outdoors. So it is a perfect chance to meet and spend time with your neighbors. Most people love to talk about their hobbies, and gardeners are no different. They usually enjoy showing people what they are growing. And most enjoy sharing advice and stories about their gardens almost as much as sharing flowers and vegetables from their gardens.
Gardening is a great activity for children. It gets them outdoors and off computers, televisions and cell phones. Gardening is also a great teacher. It can teach a child about where food comes from and healthy eating. It also helps them to understand that the natural resources (资源) are not inexhaustible and the importance of using them carefully.
Then, when you garden, you must move around. All the different movements needed for gardening, like bending and lifting, work small muscles (肌肉) in the body. And you can easily get good exercise when you are digging holes or pulling grasses.
In a study, researches looked at more than 2,800 people over the age of 60. They studied their lifestyle habits, activities and health over a 16-year period. They found that gardening could lower the risk of future dementia (痴呆) by 36%. Gardening requires people do many repeated actions, such as picking off dying flowers. These actions have a calming influence on the brain. The brain is still active but not in the same way when we use computers.
You'll feel wonderful when what you grow in a garden looks, smells, feels and tastes good.
Certain activities can be good or bad for our brains, so let's see which of the seven habits you should carry on doing or give up.
Sitting still When we sit for long periods (more than three hours), our inactivity decreases the blood flow to the brain and the oxygen supply. This decreases brain activity in the part of the brain we use for thinking, organizing and decision-making. Action: Relax the brain by getting up to stretch and move around every 30 minutes. |
Staying curious Learning new skills leads to better understanding - the brain's ability to form new connections between existing neurons(神经元). Action: Why not take up a musical instrument or an evening class? |
Fast food The quickest way to jam our brains is to fill our bodies with fast food. Too much salt leads to more brain illnesses. Action: Eat fresh and green food as much as you can. |
High-quality sleep Studies have shown being deprived(剥夺)of sleep for 24 hour decreases memory and concentration. But regular, restful sleep improves memory. Action: Try and go to bed before midnight and aim for 7-8 hours' sleep. |
Being overweight Obesity does great harm to the brain and is also a risk factor for cognitive(认知的)decline. Action; Try to lose some weight if you are too fat |
Drinking alcohol regularly Regular drinking lowers the levels of serotonin (血清素) in your brain and can make you depressed. Action: Many medical experts recommend taking regular days off from drinking to ensure you don't feel sad and don't become addicted. |
