Saco-Indonesia.com - Di waktu seseorang dituntut bekerja terlalu keras, kondisi fisik dan mental cenderung rentan mengalami kelelahan. Pada gilirannya, tingkat konsentrasi akan menurun, sehingga mengurangi efisiensi dalam bekerja.
Kelelahan merupakan salah satu biang keladi menurunnya produktivitas di tempat kerja. 

Faktanya, banyak faktor yang menyebabkan seseorang menjadi gampang kelelahan. Berbagai penelitian telah dilakukan untuk menggali masalah kelelahan saat bekerja. Beragam faktor juga ditemukan yang menjadi pemicu problem kelelahan saat bekerja.

Dalam sebuah makalah berisi kesimpulan dari berbagai penelitian mengenai kelelahan terkait pekerjaan (2006) oleh Department of Employment and Workplace Relations - Australian Safety and Compensation Council (ASCC), disebutkan sejumlah faktor yang memengaruhi kelelahan saat bekerja.
Faktor tersebut di antaranya: tuntutan pekerjaan, jam kerja, tuntutan secara fisik dan psikis dalam bekerja, psikososial, lingkungan, hubungan interpersonal, kondisi lingkungan kerja seperti suara bising, suhu, serta stres dalam bekerja, tak terkecuali pola tidur.

Di luar berbagai faktor tersebut, dalam pernyataan terpisah, Dr Jill Dorrian dari Centre for Sleep Research University of South Australia mengungkapkan kualitas tidur turut mempengaruhi kinerja dan berdampak pada kelelahan saat bekerja. Asupan air dan kafein juga turut menentukan faktor kebugaran seseorang dalam beraktivitas sehari-hari.

Dr Dorrian menyarankan, agar tetap bugar, seseorang perlu minum banyak air karena cairan bisa mencegah kekeringan pada otak. "Ketika otak terhidrasi, oksigen dan nutrien yang esensial untuk tubuh bisa berfungsi optimal," terangnya.

Selain menjaga asupan cairan, tidur juga mempunyai peran penting mengatasi kelelahan saat bekerja.

"Tidur berkualitas selama 20 menit atau kurang akan lebih baik ketimbang tidur dalam waktu lama namun saat bangun justru merasa lebih buruk," ungkap dr Dorrian.

Beragam penyebab

Penyebab kelelahan dalam bekerja menurut menurut Lifestyle Observer dan Pengajar Biologi Fisiologi Tubuh dari Shape Up Indonesia, dr Grace Judio-Kahl, MSc, MH, CHt bisa sangat beragam.  Dalam penanganannya, seseorang perlu terlebih dulu mencermati sumber masalah kelelahan tersebut.

Grace menjelaskan, bisa saja kelelahan terjadi karena seseorang memang secara fisik lelah misalnya karena kurang istirahat atau melakukan pekerjaan yang membutuhkan aktivitas fisik yang besar. Kelelahan juga bisa terjadi karena penyakit kronis atau penyakit akut.

Penyakit akut bisa disebabkan beberapa virus, termasuk virus fourth disease, fifth disease, roseola, atau hepatitis. Sementara penyakit kronis misalnya pada orang yang memiliki masalah tiroid atau diabetes.

Rasa lelah juga bisa muncul karena orang itu secara emosional punya masalah yang memicu stres. Kurang makan juga bisa menjadi penyebab kelelahan saat bekerja.

Terkait makanan dan asupan nutrisi, Grace mengatakan faktor nutrisi mungkin saja memberikan kontribusi terhadap kelelahan.

"Nutrisi memungkinkan saja ada kontribusi pada kelelahan. Misalnya untuk penyakit kronis, asupan nutrisi yang salah membuat orang itu diabetes dan penyakit itulah yang membuat dia kelelahan. Atau orang itu sedang diet, karena diet terjadi hipoglikemi, itu memungkinkan menyebabkan kelelahan," ungkapnya kepada Kompas Health melalui email.

Karenanya, lanjut Grace, dalam mengatasi problem kelelahan harus diperhatikan akar masalahnya. Jika terjadi hipoglikemi akibat diet, asupan gula tepung dan karbohidrat harus cukup.

Solusi lain dalam mengatasi kelelahan juga bisa dilakukan dengan cara mengonsumsi kafein atau makanan yang sifatnya meningkatkan metabolisme. Selain itu bisa dengan mengonsumsi vitamin B atau multivitamin, serta buah dan sayur, namun ini sifatnya hanya sementara.

"Mengatasi kelelahan secara temporer bisa saja, tapi tetap saja harus dilihat akar masalahnya. Kalau lelahnya karena stres, mau dikasih makanan apa pun tetap saja stresnya tidak sembuh dan lelahnya tidak hilang," terangnya.

Nah, jika sumber masalah kelelahan karena kekurangan gizi atau mikronutrien, dan menyebabkan kelelahan berkepanjangan, lain lagi penanganannya.
"Kelelahan berkepanjangan karena kekurangan zat gizi bisa diatasi dengan mengasup zat gizi tertentu. Misalnya, kurang darah, HB turun, mungkin kekurangan zat besi, selenium, atau  seng," ungkapnya.

Lain halnya jika kelelahan terjadi karena kerja otot berlebihan. Jadi, saat otot bergerak, seseorang bisa merasa lelah karena muncul sampah metabolisme akibat pemakaian otot. Masalah ini bisa diatasi dengan asupan zat gizi tertentu seperti asam amino.

"Banyak hal yang harus dirujuk untuk mengatasi kelelahan bekerja. Lihat dulu penyebab kelelahan, untuk menentukan lalu cari obatnya," saran Grace.

Terkait masalah asupan gizi untuk membantu kelelahan, sebuah riset di Jepang menunjukkan bahwa konsumsi saripati ayam (essence of chicken) dapat membantu memulihkan stres dan kelelahan mental.

Seperti dimuat Journal of Physiological Anthropology (Applied Human Science), Dr. Nagai dan Harada dari Institute of Fundamental Research Suntory, Jepang, melakukan penelitian melibatkan dua kelompok mahasiswa pria sehat yang diberikan tes beban kerja.  

Kelompok pertama diberi minuman saripati setiap pagi selama satu pekan, sedangkan kelompok yang lain diberikan plasebo. Pada hari ke tujuh, kedua kelompok mahasiswa ini menjalani tes kemampuan dan pengukuran kadar stres.   Tes mental untuk mahasiswa ini berupa ujian artimatika dan kemampuan daya ingat jangka pendek, yang keduanya berkaitan dengan hormon stres atau kortisol

Hasil penelitian menunjukkan, tingkat kesalahan pada kelompok pertama yang diberi minuman saripati lebih rendah dibanding kelompok plasebo. Kelompok pertama juga mengaku lebih aktif dan tidak mudah lelah selama mengikuti ujian.  Peneliti menyimpulkan, kandungan gizi dalam saripati membantu memetabolisme kortisol dalam darah dan memulihkan tubuh dari kelelahan mental.

Bila Kondisi Tubuh Cepat Lelah Saat Bekerja, Apa Sih Penyebabnya?

Hockey is not exactly known as a city game, but played on roller skates, it once held sway as the sport of choice in many New York neighborhoods.

“City kids had no rinks, no ice, but they would do anything to play hockey,” said Edward Moffett, former director of the Long Island City Y.M.C.A. Roller Hockey League, in Queens, whose games were played in city playgrounds going back to the 1940s.

From the 1960s through the 1980s, the league had more than 60 teams, he said. Players included the Mullen brothers of Hell’s Kitchen and Dan Dorion of Astoria, Queens, who would later play on ice for the National Hockey League.

One street legend from the heyday of New York roller hockey was Craig Allen, who lived in the Woodside Houses projects and became one of the city’s hardest hitters and top scorers.

“Craig was a warrior, one of the best roller hockey players in the city in the ’70s,” said Dave Garmendia, 60, a retired New York police officer who grew up playing with Mr. Allen. “His teammates loved him and his opponents feared him.”

Young Craig took up hockey on the streets of Queens in the 1960s, playing pickup games between sewer covers, wearing steel-wheeled skates clamped onto school shoes and using a roll of electrical tape as the puck.

His skill and ferocity drew attention, Mr. Garmendia said, but so did his skin color. He was black, in a sport made up almost entirely by white players.

“Roller hockey was a white kid’s game, plain and simple, but Craig broke the color barrier,” Mr. Garmendia said. “We used to say Craig did more for race relations than the N.A.A.C.P.”

Mr. Allen went on to coach and referee roller hockey in New York before moving several years ago to South Carolina. But he continued to organize an annual alumni game at Dutch Kills Playground in Long Island City, the same site that held the local championship games.

The reunion this year was on Saturday, but Mr. Allen never made it. On April 26, just before boarding the bus to New York, he died of an asthma attack at age 61.

Word of his death spread rapidly among hundreds of his old hockey colleagues who resolved to continue with the event, now renamed the Craig Allen Memorial Roller Hockey Reunion.

The turnout on Saturday was the largest ever, with players pulling on their old equipment, choosing sides and taking once again to the rink of cracked blacktop with faded lines and circles. They wore no helmets, although one player wore a fedora.

Another, Vinnie Juliano, 77, of Long Island City, wore his hearing aids, along with his 50-year-old taped-up quads, or four-wheeled skates with a leather boot. Many players here never converted to in-line skates, and neither did Mr. Allen, whose photograph appeared on a poster hanging behind the players’ bench.

“I’m seeing people walking by wondering why all these rusty, grizzly old guys are here playing hockey,” one player, Tommy Dominguez, said. “We’re here for Craig, and let me tell you, these old guys still play hard.”

Everyone seemed to have a Craig Allen story, from his earliest teams at Public School 151 to the Bryant Rangers, the Woodside Wings, the Woodside Blues and more.

Mr. Allen, who became a yellow-cab driver, was always recruiting new talent. He gained the nickname Cabby for his habit of stopping at playgrounds all over the city to scout players.

Teams were organized around neighborhoods and churches, and often sponsored by local bars. Mr. Allen, for one, played for bars, including Garry Owen’s and on the Fiddler’s Green Jokers team in Inwood, Manhattan.

Play was tough and fights were frequent.

“We were basically street gangs on skates,” said Steve Rogg, 56, a mail clerk who grew up in Jackson Heights, Queens, and who on Saturday wore his Riedell Classic quads from 1972. “If another team caught up with you the night before a game, they tossed you a beating so you couldn’t play the next day.”

Mr. Garmendia said Mr. Allen’s skin color provoked many fights.

“When we’d go to some ignorant neighborhoods, a lot of players would use slurs,” Mr. Garmendia said, recalling a game in Ozone Park, Queens, where local fans parked motorcycles in a lineup next to the blacktop and taunted Mr. Allen. Mr. Garmendia said he checked a player into the motorcycles, “and the bikes went down like dominoes, which started a serious brawl.”

A group of fans at a game in Brooklyn once stuck a pole through the rink fence as Mr. Allen skated by and broke his jaw, Mr. Garmendia said, adding that carloads of reinforcements soon arrived to defend Mr. Allen.

And at another racially incited brawl, the police responded with six patrol cars and a helicopter.

Before play began on Saturday, the players gathered at center rink to honor Mr. Allen. Billy Barnwell, 59, of Woodside, recalled once how an all-white, all-star squad snubbed Mr. Allen by playing him third string. He scored seven goals in the first game and made first string immediately.

“He’d always hear racial stuff before the game, and I’d ask him, ‘How do you put up with that?’” Mr. Barnwell recalled. “Craig would say, ‘We’ll take care of it,’ and by the end of the game, he’d win guys over. They’d say, ‘This guy’s good.’”
