At this very moment around the world, athletes are stepping almost naked into freezing cold rooms. Why on Earth are they doing this? Because it’s supposed to help them feel better.

The treatment is called whole-body cryotherapy. Basketball star LeBron James, soccer great Cristiano Ronaldo, and boxing champion Floyd Mayweather Jr. have all tried it. The therapy works like this. You take off everything but your underwear. Then you put on warm socks and gloves and step into a small room that looks sort of like a shower, except your head sticking 16% out the top. Once you’re locked in, air cooled to below -200°F(-129°C) fills the room. That’s way colder than Antarctica. You stay in for two to three minutes.

Advocates believe the extremely cold air helps muscles recover faster and reduces other body pain. After his first cryotherapy sessions, Phil Mackenzie, a professional rugby player, felt noticeably better. He told Scientific American, ‘I felt refreshed right away. My sleep was better’. Soon, he was using it four times a week. Those who promote cryotherapy make all sorts of wild claims about its benefits. Supposedly, that extremely cold air can increase focus, improve skin tone, make you happier, burn calories, slow aging, and much more.

Is there any evidence to back up these incredible claims? Nope. Several small scientific studies have looked at whether the therapy can improve muscle recovery after exercise, with encouraging results. But there just isn’t enough evidence to show that the therapy works. The benefits some people experience may just be the placebo effect. That’s when a patient’s expectation that a treatment will work leads to an improvement.

The US Food & Drug Administration has actually issued a warning about whole-body cryotherapy. It cautions that the liquid nitrogen used to cool the room may make it difficult to breathe. Frost bite is another potential risk, which is why participants wear gloves and socks.

What do you think? Is it a chance for a better athletic performance worth the risk?

9 . A vaccine (疫苗) that protects against one of the main common cold viruses has been shown to be safe and effective in a clinical trial and could be available by 2024.

Respiratory syncytial virus (RSV) spreads so easily that more than 90 percent of people have experienced their first infection (感染) by the age of 2. It usually causes cold-like symptoms but can lead to severe illness in young children and older people. All around the world, about 60,000 children under the age of 5 and 14,000 people over the age of 65 die each year after developing the virus.

Developing vaccines against RSV and other respiratory viruses has been difficult because the respiratory tract (呼吸道) is a surface exposed directly to the outside world, says Kirsten Spann at the Queensland University of Technology in Australia.

“It’s harder for antiviral antibodies (抗病毒抗体) in the blood to reach viruses in the respiratory tract, or even know they are there, because there is some physical separation,” she says.

In recent years, however, there has been rapid progress in finding new ways to improve immunity against respiratory viruses.

Several RSV vaccines are being tested in clinical trials, including one made by German company Bavarian Nordic. Its vaccine is designed to build immunity against RSV by exposing me body to five small fragments of the virus.

In a clinical trial involving 420 adults aged 55 and older, a single injection (注射) of the vaccine in the upper arm increased the levels of RSV-fighting antibodies inside the nose by three times and caused no serious side effects.

This immune response lasted for six months ---- enough to cover a winter cold season ---- and was restored with a booster shot at 12 months.

The results are promising, but more research is needed to see if the immune response is strong enough to prevent RSV infections, says Spann.

Bavarian Nordic is now planning a bigger clinical trial of its RSV vaccine that is scheduled to begin in 2021 and will involve more than 12,000 adults. If the results are positive, the company hopes to make the vaccine available by 2024. The firm plans to offer the vaccine to children too, but not until it has passed clinical trials involving people in this age range

10 . Historically, human beings have had a deep relationship with the horse, not just as a partner in our labors, but as an inspiration in art, mythology, music and poetry. In fact, our use of the horse as a work animal may be the most obvious yet least interesting aspect of the lasting bond that we have shared with this fascinating animal.

The therapeutic value of riding was documented as early as 600 B.C. by Orbasis of ancient Lydia. It wasn’t until 1875, however, that the first systematic study of therapeutic riding was reported. After prescribing pony riding as a treatment for a variety of conditions, French physician Chassaign concluded that riding was helpful in the treatment of certain types of neurological paralysis. He noted improvement in posture, balance and joint movement, and a striking increase in morale.

In 1946, following two outbreaks of polio, riding therapy was introduced in Scandinavia. This movement was led by Liz Hartel, an accomplished horsewoman who was stricken with it. After surgery and physical therapy allowed her to walk with crutches, Hartel was determined to ride independently again. Daily riding sessions brought back her muscle strength. In 1952, she won the Olympic silver medal for dressage.

Presently, more than 600 therapeutic riding programs are member centers of the North American Riding for the Handicapped Association (NARHA), located in Denver. Founded in 1969, NARHA establishes professional guidelines, safety standards, and instructor and therapist training and certification for the growing field of equine-assisted activities (EAA) and -therapies (EAT).

For individuals with physical or psychological disabilities, therapeutic riding can prove beneficial in several ways. They may experience increased strength and balance, improved body awareness, and increased self-confidence. The positive relationship that develops between a rider and her horse and therapeutic team presents opportunities for the development of trust and social growth.
