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.

▲It’s easy on the body.

Tai chi is suitable for all ages and levels of fitness. It is low-impact, meaning there is minimal risk of damage to your joints.     2     It’s an exercise that can be easily adapted for less able people, including those in wheelchairs.

A 2019 review of studies suggested that Tai Chi might reduce the risk of falls in older people.     3     It also improves flexibility and spatial awareness.

▲     4    

Tai Chi may boost brain power. Studies have found that regular Tai Chi can improve cognitive functioning in older people with dementia(痴呆)and without. Given that it’s considered safe and suitable for the elderly, this is a definite win. It also has the feel-good factor. A reduction in stress and anxiety, and increased confidence, are other mental health benefits of Tai Chi, according to research, though further research is needed.

7 . Working out during the height of a heatwave is one way to make your heart rate rise. But does it really burn more calories? Here’s everything you need to know about working out in extreme heat.

Is it safe to exercise in hot weather?

    1    In fact, it might even help you get a better night’s sleep. Make sure to stay hydrated (含水的) throughout your session and try to time the workout either at the start or end of the day when the temperatures have dropped. The heatwave makes it all the more important to listen to your body when it’s telling you to stop.     2    All of these are symptoms of heatstroke (中暑) which can be deadly, after all.

Do you burn more calories in a heatwave?

Working out in hot weather not only pushes your body to work harder to cool down, it also burns more calories in the process.     3    Thus your heart works harder in hotter temperatures than it would in cooler temperatures, providing an increased calorie and fat burn.

But while working out in a heatwave does in fact burn calories, chances are the heat will also cut your gym session short.     4    Because your body is working hard to keep you cool while the weather itself means you can exercise for longer.

What is the best form of exercise during a heatwave?

Although boxing has been considered as the best calorie -burning exercise around, it’s more efficient to choose an outdoor sport during a period of hot weather.     5     Running outside is close behind with 700. Just imagine how calorie-burning they must be in the heat.

A．Make sure you exercise safely in the sunshine.

B．Ideally, warm is the best temperature for burning calories.

C．Generally speaking, it is totally safe to exercise in hot weather.

D．After all, in normal conditions rowing is said to burn 740 calories per hour.

E．An early morning workout is therefore always a better option in the hot weather.

F．If you start feeling dizzy or find your heartbeat rapidly increasing, it’s time to stop.

G．The hotter your body gets, the more blood your heart needs to pump (输送) to force out heat.

8 . Surf’s Up

Riding the wave can be the thrill of a lifetime. But what does it take to become a surfer?

Surfing—it’s addictive

Surfing is the most exciting watersport there is. Serious surfers must be very brave, love adventure and have lots of energy. Once they’ve experienced the excitement of a ride on top of the waves, they never want to stop.

Finding the waves

Many surfers travel around the world searching for the perfect wave, moving from one surf festival to another and checking weather forecasts to see where the really exciting waves are expected next. A surfer’s greatest disappointment would be missing the opportunity to surf in the best weather conditions.

The international sports

Hawaii is where the sports began—the place which most surfers see as their “true home”. They love nature and the excitement they get from the deep waters. Enormous waves crash along mile after mile of beautiful sand, and every surfer dreams of experiencing surfing in Maui or Oahu. Other greatest locations include Australia, the west coast of the US, the Caribbean, Brazil, South Africa, The Canary Islands, and Cornwall.

Two essentials: strength and fearlessness

It takes time for a beginner to learn the technique, but during a long hot summer, who minds practising? The professionals are in the sea every day, and then come back onto the beach to do some exercise. They need to be strong swimmers with good balance and plenty of courage to be expert surfers.

Never easy—but always enjoyable

It can take a few weeks or a whole summer for you to learn to catch a wave at the right moment, stand up on your board and stay there. It’s an amazing feeling when you look down and see your feet on the board and realize you are finally standing up on the sea, even if you aren’t very steady.
