1 . Scientists are now digging into precisely why exercise holds so many benefits for our mental health and memory. The answer, studies say, lies in our brain chemistry.
Each time you work up a sweat, your body releases feel-good happy hormones (荷尔蒙), including endorphins, dopamine and endocannabinoids, the latter being responsible for the so-called runner’s high. Now researchers are also pointing to myokines (肌肉因子) as an important contributor to the mental health benefits of exercise. When our muscles contract, myokines are released into the bloodstream, helping your muscles and organs communicate. They think this communication increases resilience to stress, reduces symptoms of mental suffering and anxiety and has a direct effect on depression.
A 2021 scientific report published in Neuropharmacology showed evidence that myokines boost brain function, like improving memory and mood. “Myokines reduce systemic inflammation (炎症), which is especially beneficial for people with drug-resistant depression whose low mood is linked to high inflammation,” explains Dr Jennifer Heisz, an expert in brain health and associate professor in the department of kinesiology at McMaster University in Canada.
A recent study published in the British Journal of Sports Medicine showed that treatment for depression can be much more effective when physical activity is added to the usual care. Participants found benefits after 12 weeks of exercising for 30 to 60 minutes a day. “While exercise is not a replacement for professional mental health treatment, physical activity can complement and enhance the effects of the treatment,” says lead researcher Ben Singh, a research fellow at the University of South Australia.
“It is amazing to consider how moving our bodies can heal our minds,” says Heisz. Whether you’re cycling, walking around your neighbourhood or doing yoga, getting sweaty is good for your body and mind. To get the biggest overall health boost, the key is to zero in on sports and activities you enjoy, so you’ll keep going back to them.

3 . For anyone who has exercised for some purposes, you probably have experienced disappointment and even a sense of lack of fulfillment.
One of the biggest reasons is that it helps in weight loss. Exercising every day helps you burn a lot of calories. It also helps in toning (调整) your body and giving it a better appearance.

4 . Sports offer so many great benefits not only to our physical health but to our mental health.

7 . Want to feel better, have more energy and even add years to your life? Just exercise.
Exercise controls weight
Exercise can help prevent too much weight gain or help you keep off lost weight. When you take part in physical activity, you burn calories. Regular trips to the gym are great, but don’t worry if you can’t find a large block of time to exercise every day. To gain the benefits of exercise, just get more active throughout your day.
Exercise improves mood
Need an emotional lift? Or need to lower stress after a stressful day? A gym session or quick walk can help.
Regular physical activity can improve your muscle strength and boost your tolerance. Exercise sends oxygen and nutrients to your tissues and helps your cardiovascular (心血管的) system work more efficiently. And when your heart and lung health improve, you have more energy to tackle daily chores (杂活).
Exercise can be fun-and social!

10 . The rise of body neutrality You define (定义) beauty yourself. You are more than a number in measurement. Love yourself the way you are. Body positive messages like theses seem to be everywhere from social media to TV advertisements.
Body positivity’s aim to boost acceptance and appreciation of a variety of body types and sizes may explain why it has such a broad appeal. While some find the body positivity movement to be helpful, others have begun calling the movement toxic and suggesting it may be time to move on from this way of thinking.
More recently, people have voiced concerns. Some feel that the focus on loving your looks actually strengthens society’s stress on appearance over other values. Much body positivity content in advertisements may bring a stereotype (刻板印象) to viewers because it does little to challenge the hidden assumption that people are valued mainly for their appearance. Therefore, the movement still encourages people to be graceful and engage in beauty practices from head to toe. And if you fail to be body positive, it’s you that are at fault.
Many are now moving away from the body positivity movement and the pressures that come from it entirely, and instead are getting behind the body neutrality (中立) movement. Instead of focusing on physical appearance, body neutrality is a profound idea that we can exist without having to think too much about our bodies.
We are all more than just our bodies. We are complicated beings with a range of emotions and feelings about our bodies. And because body neutrality de-emphasizes (不强调) the focus on appearance, it motivates us to better acknowledge all the things our bodies are able to do. Being grateful for being able to take up your hobbies and appreciating your body for what it’s capable of doing are both examples of body neutrality.
Body neutrality can be beneficial to us. It is associated with the positive body image and mental well-being. The good news is that there are many ways you can develop body neutrality, including writing-based treatment, yoga and spending time in nature.
