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?

As he reflected on the festering wounds deepened by race and grievance that have been on painful display in America’s cities lately, President Obama on Monday found himself thinking about a young man he had just met named Malachi.

A few minutes before, in a closed-door round-table discussion at Lehman College in the Bronx, Mr. Obama had asked a group of black and Hispanic students from disadvantaged backgrounds what could be done to help them reach their goals. Several talked about counseling and guidance programs.

“Malachi, he just talked about — we should talk about love,” Mr. Obama told a crowd afterward, drifting away from his prepared remarks. “Because Malachi and I shared the fact that our dad wasn’t around and that sometimes we wondered why he wasn’t around and what had happened. But really, that’s what this comes down to is: Do we love these kids?”

Many presidents have governed during times of racial tension, but Mr. Obama is the first to see in the mirror a face that looks like those on the other side of history’s ledger. While his first term was consumed with the economy, war and health care, his second keeps coming back to the societal divide that was not bridged by his election. A president who eschewed focusing on race now seems to have found his voice again as he thinks about how to use his remaining time in office and beyond.

Obama Speaks of a ‘Sense of Unfairness’

Obama Speaks of a ‘Sense of Unfairness’

At an event announcing the creation of a nonprofit focusing on young minority men, President Obama talked about the underlying reasons for recent protests in Baltimore and other cities.

In the aftermath of racially charged unrest in places like Baltimore, Ferguson, Mo., and New York, Mr. Obama came to the Bronx on Monday for the announcement of a new nonprofit organization that is being spun off from his White House initiative called My Brother’s Keeper. Staked by more than $80 million in commitments from corporations and other donors, the new group, My Brother’s Keeper Alliance, will in effect provide the nucleus for Mr. Obama’s post-presidency, which will begin in January 2017.

“This will remain a mission for me and for Michelle not just for the rest of my presidency but for the rest of my life,” Mr. Obama said. “And the reason is simple,” he added. Referring to some of the youths he had just met, he said: “We see ourselves in these young men. I grew up without a dad. I grew up lost sometimes and adrift, not having a sense of a clear path. The only difference between me and a lot of other young men in this neighborhood and all across the country is that I grew up in an environment that was a little more forgiving.”

Organizers said the new alliance already had financial pledges from companies like American Express, Deloitte, Discovery Communications and News Corporation. The money will be used to help companies address obstacles facing young black and Hispanic men, provide grants to programs for disadvantaged youths, and help communities aid their populations.

Joe Echevarria, a former chief executive of Deloitte, the accounting and consulting firm, will lead the alliance, and among those on its leadership team or advisory group are executives at PepsiCo, News Corporation, Sprint, BET and Prudential Group Insurance; former Secretary of State Colin L. Powell; Senator Cory Booker, Democrat of New Jersey; former Attorney General Eric H. Holder Jr.; the music star John Legend; the retired athletes Alonzo Mourning, Jerome Bettis and Shaquille O’Neal; and the mayors of Indianapolis, Sacramento and Philadelphia.

The alliance, while nominally independent of the White House, may face some of the same questions confronting former Secretary of State Hillary Rodham Clinton as she begins another presidential campaign. Some of those donating to the alliance may have interests in government action, and skeptics may wonder whether they are trying to curry favor with the president by contributing.

“The Obama administration will have no role in deciding how donations are screened and what criteria they’ll set at the alliance for donor policies, because it’s an entirely separate entity,” Josh Earnest, the White House press secretary, told reporters on Air Force One en route to New York. But he added, “I’m confident that the members of the board are well aware of the president’s commitment to transparency.”

The alliance was in the works before the disturbances last week after the death of Freddie Gray, the black man who suffered fatal injuries while in police custody in Baltimore, but it reflected the evolution of Mr. Obama’s presidency. For him, in a way, it is coming back to issues that animated him as a young community organizer and politician. It was his own struggle with race and identity, captured in his youthful memoir, “Dreams From My Father,” that stood him apart from other presidential aspirants.

But that was a side of him that he kept largely to himself through the first years of his presidency while he focused on other priorities like turning the economy around, expanding government-subsidized health care and avoiding electoral land mines en route to re-election.

After securing a second term, Mr. Obama appeared more emboldened. Just a month after his 2013 inauguration, he talked passionately about opportunity and race with a group of teenage boys in Chicago, a moment aides point to as perhaps the first time he had spoken about these issues in such a personal, powerful way as president. A few months later, he publicly lamented the death of Trayvon Martin, a black Florida teenager, saying that “could have been me 35 years ago.”

That case, along with public ruptures of anger over police shootings in Ferguson and elsewhere, have pushed the issue of race and law enforcement onto the public agenda. Aides said they imagined that with his presidency in its final stages, Mr. Obama might be thinking more about what comes next and causes he can advance as a private citizen.

That is not to say that his public discussion of these issues has been universally welcomed. Some conservatives said he had made matters worse by seeming in their view to blame police officers in some of the disputed cases.

“President Obama, when he was elected, could have been a unifying leader,” Senator Ted Cruz of Texas, a Republican candidate for president, said at a forum last week. “He has made decisions that I think have inflamed racial tensions.”

On the other side of the ideological spectrum, some liberal African-American activists have complained that Mr. Obama has not done enough to help downtrodden communities. While he is speaking out more, these critics argue, he has hardly used the power of the presidency to make the sort of radical change they say is necessary.

The line Mr. Obama has tried to straddle has been a serrated one. He condemns police brutality as he defends most officers as honorable. He condemns “criminals and thugs” who looted in Baltimore while expressing empathy with those trapped in a cycle of poverty and hopelessness.

In the Bronx on Monday, Mr. Obama bemoaned the death of Brian Moore, a plainclothes New York police officer who had died earlier in the day after being shot in the head Saturday on a Queens street. Most police officers are “good and honest and fair and care deeply about their communities,” even as they put their lives on the line, Mr. Obama said.

“Which is why in addressing the issues in Baltimore or Ferguson or New York, the point I made was that if we’re just looking at policing, we’re looking at it too narrowly,” he added. “If we ask the police to simply contain and control problems that we ourselves have been unwilling to invest and solve, that’s not fair to the communities, it’s not fair to the police.”

Moreover, if society writes off some people, he said, “that’s not the kind of country I want to live in; that’s not what America is about.”

His message to young men like Malachi Hernandez, who attends Boston Latin Academy in Massachusetts, is not to give up.

“I want you to know you matter,” he said. “You matter to us.”
