2 . This summer, climate change continues to push Earth’s weather to extremes.     1     The short answer is yes, if you take precautions. We invite some experts to discuss the science behind exercising in the heat and offer some tips on how to exercise outdoors safely in the heat. Here are some of them.

1.     2    

Doesn’t our body need fuel to move? Yes, that’s true. A light meal is a great idea — just put an hour between eating and your workout in the heat. It takes blood and energy to digest the food, which makes more body heat — not what you want when you’re already hot. If you have had a heavy meal like a cheeseburger, you should wait two to three hours before your hot outdoor exercise, since that fat-and protein-rich meal will take even longer to move through the digestive process.

2. Protect your skin — it’s the body’s cooling system.

Your skin and the underlying tissues are incredibly designed to move warm blood away from your core to keep your vital organs cool. Damage to them prevents your body from air-conditioning itself. To protect your skin, start with sunscreen.     3    

3. Wear material that will help your body breathe.

    4     Wear sweat-wicking (吸汗的) athletic clothing that allows your skin to cool. Avoid materials like cotton that basically keep the heat close to your body.

4. Drink water before, during and after exercise.

Dehydration (脱水) can really secretly attack you.     5     Make sure you drink water at least an hour before you head out to exercise. Besides, keep drinking while you’re working out. More importantly, replenish (补充) what’s lost during your workout after you finish your workout.

3 . 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.

6 . If you hope to improve your health, exercise is obviously a good way. But do you know that it has great effects on the mind too? We often pay little attention to the great mental benefits that exercising regularly can have. It will allow you to stay active and healthy for a long time, allowing you to have both the physical and mental (身心的) benefits.    1    

Improve your mood (心情) . Exercise is just what you need if you’re looking for some positive feelings. It is possible that you have experienced a happy time after exercise. While you are exercising, “happiness hormones (荷尔蒙)” are released.     2    

Reduce stress. If you’re feeling stressed, this feeling will disappear after exercise.    3    Because it helps reduce the level of the “stress hormone” which leaves you feeling tired and stressed.

    4    If you take regular exercise, you’ll find the results last longer too. So over time, you’ll have a higher ability to stay focused while completing tasks if you exercise regularly.

Improve your memory. According to a study by the University of British Columbia, regular exercise increases the size of the hippocampus (a part of the brain).    5    

So, it is clear to see that there are many different benefits regular exercise can have. With these benefits for the mind, there now shouldn’t be any excuse not to start and lead an active, balanced life.

7 . Maybe you plan to ring in 2023 with a new resolve to lose weight, exercise more, not sweat the small stuff. And maybe these resolutions sound familiar — maybe just like the ones you made a year ago! So how can you ensure that your determination to get healthier in 2023 sticks?    1    

Dream big. Want to compete in a marathon or triathlon? Lose 50 pounds or just enough to fit into clothes you once loved? With perseverance (毅力), encouragement, and support, you can do it.     2    Many will cheer you on. Some will be happy to help in practical ways, such as by training with you or taking on tasks you normally handle in order to free up your time.

    3    Any time you fail to make a change, consider it a step toward your goal. Why? Because each sincere attempt represents a lesson learned. When you hit a snag (碰钉子), take a moment to think about what did and didn’t work. Maybe you took on too big a challenge?     4    

Give thanks for what you do. Set your sights on finishing that marathon,not on running it. If you compete to complete, you’ll be a winner even if you wind up walking as much as you run. With exercise — and so many other goals we set — you’ll benefit even when doing less than you’d like to do.     5    If your goal for Tuesday is a 30-minute workout at the gym, but you only squeeze (挤出) in 10 minutes, feel grateful for that. It’s enough. Maybe tomorrow will be better.

8 . Jumping rope is popular but we tend to ignore (忽视) its benefits.     1     A study found that college men who spent 10 minutes jumping rope daily for six weeks improved their cardiovascular (心血管的) fitness just as much as college men who spent thirty minutes jogging for the same time. Here are some benefits of jumping rope.

    2    

Since most of your major muscles are working when you jump rope, the exercise creates a lot of heat in the body. Your body needs to burn more fuel to produce this energy, so it burns lots of calories. It burns more calories than any other exercises, such as jogging, cycling and swimming.

Improves coordination (协调)

Jumping rope requires good coordination, especially as you advance to more skilled moves.     3     It improves coordination by requiring several body parts to communicate in order to complete one movement. The feet must jump in time with the wrists turning in order to create a continuous jumping motion.

Reduces injury risk

With your improved coordination from jumping rope, you’ll be less likely to get hurt either during exercise or in daily activities.     4     As a result, you are more agile (灵活的) and your body awareness is improved greatly. This guarantees fewer injuries.

Improves heart health

Since jumping rope gets your heart pumping, it’s great for your cardiovascular system and heart health. Jumping rope can increase your VO₂ Max (最大摄氧量), the measure of the maximum amount of oxygen a person can breathe during exercise. The higher someone’s VO₂ max, the more cardiovascular endurance (耐受力) they have.

Jumping rope gives us a full-body workout with just one piece of equipment and one move.     5     Jump to some music, or take your rope to a nearby park to enjoy the fun.
