【 七種表現說明你身體健康 】

1.相對清澈、充沛的尿液。

如果每日小便幾次，且尿液呈淡黃色，不渾濁、色暗或者太黃，說明身體的水分充足，而且腎臟健康。如果尿液完全無色，可能意味著補水過多，或者身體流失了鹽分以及電解質。除了尿液的顏色深淺變化外，還要注意氣味，呈甜味或者怪味、顏色變紅等應引起注意。

2.規律排便。

如果便中不含血、不太松散又不太硬，且排便時間有規律，能將體內垃圾迅速有效地排出體外，就說明你的飲食中有足夠的纖維，消化係統也處于良好狀態。

3.穩定的體重。

體重處于正常范圍，而且保持大體穩定，也是健康的標志之一，如果體重突然出現大幅波動，或者食量猛增或驟減時，都應引起注意。

4.傷口愈合快。

小傷口如割傷、擦傷或燒傷，如果能很快愈合，那麼祝賀你，你的血液處于健康狀態。如果輕輕按壓皮膚就有莫名的淤青出現，就該及時就醫。

5.健康的頭發和指甲。

皮膚係統(包括頭發和指甲)常常能最先提示你是否缺維生素，缺維生素通常表現為指甲脆弱、易變形，頭髮大量脫落等。健康個體的指甲通常呈粉色、而且堅硬圓潤。而皮膚要有彈性，用手按一下，能很快恢復正常。

6.女性有規律的經期，男性射精量達一勺。

按時到來的經期是證明女性生殖係統健康的最重要指標。健康中年男性每次射精量應為2—5毫升，少于2毫升可能是精子過少症的徵兆；健康男性的精液應該呈白色或灰色的黏稠狀。精液帶血或者太稀，應及時去醫院檢查。

7.不錯的睡眠。

偶爾睡眠不足或者失眠都是正常的，只要你的睡眠大體有規律而且沒有盜汗或多次起夜如廁的情況，那麼就基本符合良好睡眠的要求了，如果醒來時感覺精神不錯，也是很好的健康信號。

Kayla Wheeler has only one limb, but enough talent to compete in swimming on a world stage

LYNNWOOD — For as long as she can remember, Kayla Wheeler has loved to swim.

She was first introduced to the water when she was 18 months old as part of a hydrotherapy program. 

The 13-year-old Lynnwood girl was born without legs. She is missing her right arm above the elbow and has a fused left elbow. The goal of the therapy was for Kayla to learn how to move around and to be able to get herself upright. The therapists worked on those skills in the water and once Kayla mastered them, she was able to transfer them outside the water.

Kayla's parents, Joyce and Dean, realized how much she loved being in the water during the hydrotherapy sessions.

“I feel different in the water. I don't feel any limits or anything like that. I feel totally weightless,” said Kayla, an eighth-grader at Madrona K-8 School. 

Later on, the Wheelers sought out swim lessons for Kayla, mainly out of safety concerns.

“I just wanted to make sure if something happened and she fell into the water that she could upright herself and be OK until somebody could get her help,” Joyce Wheeler said.

What started as therapy turned into a major passion in Kayla's life.

Kayla is in Rio de Janeiro this week to compete in the 2009 International Paralympic Committee's first Short Course Swimming World Championships. The meet runs through Saturday and features more than 260 athletes from 31 different countries. Kayla is the youngest member of the United States team. She will be swimming in the 50-meter butterfly and the 50 and 100 freestyles.

Kayla competed in a qualifying meet in Edmonton, Alberta, last July. Her time of 1 minute, 41.40 seconds in the 50 butterfly earned her the spot on the U.S. team. The time was the fourth fastest in the world in her classification and also is an American record.

Swimmers are ranked from S1-S10 based on their disability, with S1 being the most disabled and S10 being the least. Kayla is an S3.

“I just kind of swam to get my times and get my face out there,” Kayla said. “I wasn't really swimming to be picked for the meet.”

When she arrived home, Kayla received an e-mail informing her that she was selected for the Paralympic team. At first Kayla and her mother weren't sure she would be able to attend the meet because of costs, but they found out that the expenses would be picked up by the U.S. team.

Still a mystery

That Kayla one day would become an athlete challenging for world records was the furthest thing from Joyce Wheeler's mind when her daughter was born. Up until the day she gave birth, she experienced a healthy, normal pregnancy.

“My mom didn't even know I was going to be born without any of my limbs until after I was born,” Kayla said.

The Wheelers saw genetic doctors and specialists after Kayla's birth, but no one was able to determine the exact cause of her limb deficiency. The doctor's best guess was that Kayla suffered some type of vascular problem, such as a blood clot, when she was developing.

Kayla underwent a battery of tests after she was born. No other problems surfaced.

“Other organs like your kidneys develop at the same time as the limbs,” Joyce Wheeler said. “But as far as we know she is healthy otherwise. She just seems to be missing some parts.”

Kayla's brain was not affected by what happened. She consistently brings home good grades and already is doing high school math, Joyce said.

Learning experience

Kayla met a kindergarten teacher, Lib Rust, who became her swim instructor. Before she met Rust, Kayla didn't have much luck working with other swim instructors.

“Before I'd go to other little swim lessons. (The instructors) wouldn't really teach me,” she said. “They'd let me play around in the pool. It didn't really help out at all.”

Rust agreed to take on the challenge of teaching Kayla. It turned out to be a learning experience for both Wheeler and Rust. “Some of the strokes you had to adapt to what is going to work best for her,” Rust said. “It's kind of experimental. ‘Well, let's try this.' ”

Through her lessons with Rust, Kayla learned the stroke mechanics to keep her body in line and not to swim in circles. She also figured out how to swim underwater and to upright herself in the pool.

In the spring of 2007, Kayla joined the Shadow Seals, a swim team for people with disabilities in Renton. Later, so she could have more pool time, she joined the Edmonds-based Barracuda swim team, which is coached by Rust's twin sister, Amy.

People often are shocked when they see Kayla swimming with her teams.

“She's freaked out a few lifeguards in her time,” Joyce Wheeler said.

Kayla admits that sometimes she's had a little fun at their expense.

“I'd jump off the side of the pool or something and they're like, ‘Aaaaugh, she's drowning!' ” she said. “Then I'd pop back up and I'd start swimming.”

Lifeguards aren't the only ones to take notice of Kayla. Some other disabled individuals were inspired to start swimming after they saw Kayla and what she was able to do in the pool, Joyce Wheeler said. 

The Rust sisters also have been inspired by working with Kayla.

“It's really opened our eyes to what you can accomplish,” Amy Rust said.

“You learn to never give up on somebody,” Lib Rust said. “You keep at it and you just keep at it and know that there are no boundaries if somebody wants to keep going.”
