Rest or risk: Korea mandantes breaks for outdoor workers in deadly heat
casualties, say experts
South Korea will require outdoor workers to receive at least 20 minutes of rest every two hours when apparent temperatures exceed 33 degrees Celsius from as early as next week, the Ministry of Employment and Labor said Friday.
The new rule — part of a revision to the Occupational Safety and Health Standards — was passed during a review by the Regulatory Reform Committee on Friday. It had been initially rejected in April and May over concerns that it would overburden small and medium-sized enterprises.
The revision was made following mounting criticism from labor groups and a surge in heat-related deaths among outdoor workers during the relentless and intense heat.
In recent days, more than 1,000 cases of heat-related illness have been reported — over twice the number recorded during the same period last year — as record-high temperatures grip the country.
According to the Korea Disease Control and Prevention Agency's heat-related illness emergency room surveillance system, 1,357 patients had visited emergency rooms by Thursday due to heat-related illnesses, with nine deaths reported.
The majority of cases, comprising 28.7 percent of the total, occurred at outdoor workplaces like construction sites.
On Monday, a Vietnamese day laborer in his 20s was found dead at an apartment complex construction site in Gumi, North Gyeongsang Province. Authorities suspect the cause of his death to be a heat-related illness, as his body temperature was over 40 degrees Celsius when found. Gumi also saw daytime temperatures reach as high as 38.3 C on the same day.
On July 3, a Filipino seasonal worker in his 30s was found unconscious at a field in Yeongju, North Gyeongsang Province. The worker was immediately transported to the hospital, with medical authorities suspecting he collapsed due to heat-related illness.
As Korea continues to break summer heat records year after year, the government has in the past emphasized three basic principles for responding to heat waves — water, shade and rest.
The Labor Ministry has also recommended that all work outdoors be suspended during heat waves — though such recommendations weren't legally binding.
Korea behind on worker heat rules
However, according to workers, such guidelines were not properly implemented.
According to a study conducted by the Korean Confederation of Trade Unions in 2024, around 15 percent of outdoor workers reported not receiving water on site and only 20 percent of respondents indicated that they had been able to stop work during heat waves.
'The problem behind Korea's policies on working conditions for outdoor workers in summer is that they're mere recommendations and are not legally mandated,' sociology professor Lee Byoung-hun from Chung-Ang University told The Korea Herald.
'Korea needs a legislated work stoppage system based on the Wet Bulb Globe Temperature index, similar to California, to effectively respond to heat waves.'
The WBGT index mentioned by professor Lee is a measure of heat stress in direct sunlight that considers temperature, humidity, wind speed and solar radiation and is used to assess the risk of heat-related illnesses during outdoor activities.
'Although Korea is seeing record-breaking summer temperatures every year, its protective measures for those working outdoors in the heat lag significantly behind other countries,' Lee added, mentioning Greece as an example.
Greece recently saw temperatures reaching as high as 40 C, prompting the Greek government to order a temporary suspension of outdoor labor and delivery services in parts of the country, according to the Associated Press on Monday.
'Mandatory rest periods, wearing cooling vests as well as the installation of cooling equipment should be mandated by the government to make sure such working guidelines are properly implemented,' Lee added.

No purchase needed: Businesses offer heat relief to the public
Amid the sweltering summer heat, commercial spaces such as convenience stores and banks in South Korea are opening their doors as cooling stations for the public. BGF Retail, the operator of CU convenience stores, said Thursday that its more than 18,000 branches nationwide will welcome all passersby, especially children, the elderly and pregnant women, to cool off without requiring a purchase. CU stores across the country began putting up signs about the policy on the same day. The latest campaign comes as the number of people suffering from heat-related illnesses continues to climb during the heat wave. On Tuesday alone, 136 people across the country were admitted to emergency rooms due to heat-related illnesses, nearly double the number on the previous day. So far, 1,860 people have fallen ill from the heat and nine have died, according to the Korea Disease Control and Prevention Agency. 'With the country's largest network of convenience stores, we aim to serve as a safety net for the public,' a CU official said. Local banks, which have long served as de facto heat shelters thanks to their strong air conditioning and cold water dispensers, also welcome people seeking relief from the summer heat, with some even setting up a designated space for them. Based on a 2018 agreement with the Financial Services Commission, banks, mutual finance institutions and savings banks have provided cooling spaces at 5,054 locations nationwide. In response to the record-breaking heat, they recently expanded the number to over 14,000 locations. These shelters will operate from 9 a.m. to 4 p.m. daily until Sept. 30, the end of the government-designated heat response period. However, despite the good intentions behind businesses' efforts to respond to the heat wave, some have voiced concerns about potential downsides to opening up private commercial spaces to the public. 'What if there's no seat left when I want to eat alone at a convenience store? I might not get a spot even if I pay,' one user wrote on X. Another commented, 'Banks are already packed with people cooling off. This will just make it more chaotic.' Intense heat is expected to continue into the weekend, with Seoul forecast to reach a high of 38 degrees Celsius on Saturday. Nighttime temperatures are also expected to remain high, nearing 30 degrees, a level considered a "super tropical night," according to the Korea Meteorological Administration.

South Korea's health insurance crackdown reduces foreign dependents
A year after South Korea introduced stricter health insurance rules for foreign residents, misuse of the system has noticeably dropped, especially among Chinese nationals. According to the National Health Insurance Service, the number of Chinese dependents enrolled under Korea's national health insurance fell from 111,059 in March 2024 to 106,243 in March 2025. That is a decrease of nearly 5,000 people within one year. The policy change was introduced amid growing concerns that foreign nationals were listing non-resident family members as dependents to access medical care in Korea at little or no cost. Many of them traveled briefly to Korea for treatment, without ever paying into the system. Chinese nationals, who make up a large share of Korea's foreign population, were the most frequent users of this loophole. In some cases, individuals registered not just immediate family but also distant relatives to receive covered procedures. In response, the government amended the law in April 2024. Now, any foreign dependent must reside in Korea for at least six consecutive months before becoming eligible for coverage. The financial impact has been substantial. NHIS data shows that health insurance accounts linked to Chinese nationals moved from a 2.7 billion won ($2 million) deficit in 2023 to a 5.5 billion won surplus in 2024. Other nationalities showed similar trends. Vietnamese dependents fell from 20,499 to 18,881, while Americans decreased from 6,673 to 6,207. Surpluses linked to those groups increased by 37.6 billion won and 5.3 billion won, respectively. Overall, the total surplus generated by foreign dependents rose from 730.8 billion won to 943.9 billion won over the past year. 'There was a clear improvement in the financial balance after the reform,' said an NHIS official. 'The effect was especially noticeable among Chinese nationals, who account for nearly half of all foreign residents in Korea.'

Vietnam's Dairy Pride: Vinamilk Makes Headlines at Growth Asia Summit with 6-HMO Breakthrough
SINGAPORE, July 17, 2025 /PRNewswire/ -- At the Growth Asia Summit 2025, which took place from July 15–17 in Singapore, Vinamilk was honored to be the only Vietnamese company invited as a keynote speaker. The Growth Asia Summit is the largest forum for growth opportunities in the food, beverage, and nutrition industries in Asia. The brand made a remarkable impression with its innovative 6-HMO infant formula, setting a new standard in pediatric nutrition and paving the way for the dairy industry in Asia. Vinamilk's presence at the Summit is symbolic; it reflects the nation's transformation from a country once struggling with post-war milk shortages into a rising nutrition powerhouse with Vinamilk at its forefront. The company currently ranks sixth globally for dairy brand value and was recognized as the most valuable food and beverage brand in Southeast Asia in Brand Finance's Food and Drink 2023 ranking. Additionally, it is the only Vietnamese dairy company featured in the Fortune Southeast Asia 500 ranking (2024), underscoring its strong market presence in the region. In Vietnam, around 55% of infants are not exclusively breastfed during their first six months [1]. This means many babies may miss out on the full range of benefits found in breast milk, especially human milk oligosaccharides (HMOs), which support gut and immune development. To address this gap, Vinamilk pioneered Vietnam's first formula containing six HMOs [2] –nutrients naturally found in breast milk—to enhance both digestive and immune health. This solution is particularly impactful in a country where nearly 60% of working mothers struggle to balance both work and family commitments. This challenge is not unique to Vietnam. Across Asia, exclusive breastfeeding rates remain modest, reaching only 52.9% in the Asia-Pacific and 48.3% in Southeast Asia [3] primarily due to lifestyle shifts, work demands, and social pressure. This is why nutrition solutions that closely mimic breast milk, such as Vinamilk's 6-HMO innovation, received extensive attention from the Summit's expert community. "I commend Vinamilk's breakthrough not only for advancing nutritional science with Vietnam's first 6-HMO formula, but also for its empathetic, consumer-centric approach. This is a valuable contribution to the Summit's mission of seeking comprehensive health solutions—not just in terms of nutrition, but also in creating positive social impact, especially for women and children," said Gary Scattergood, Editor-in-Chief of FoodNavigator Asia and NutraIngredients Asia, the Summit's organizing entities. Once a market dominated by imported dairy products, Vietnam is now home to Vinamilk, the first local brand not only to catch up, but to lead regional innovation in pediatric nutrition. While the market had plateaued at 5-HMO formulas since 2021, Vinamilk chose not to compromise and instead accelerated its R&D efforts to break this ceiling. In 2023, Vinamilk entered strategic partnerships with six leading global nutrition companies (DSM – Switzerland, Novonesis, formerly Chr. Hansen – Denmark, Beneo – Germany, Gnosis – Italy, AAK – Sweden, and Kanematsu – Japan) to enhance scientific capability and innovation in infant formula development. The launch of the Optimum line, powered by a 6-HMO formula that accounts for approximately 58% of the total HMO composition found in natural breast milk [4], exemplifies the successful integration of research and international collaboration. The 6-HMO innovation brings significant benefits for infant digestion and immunity. It mimics critical oligosaccharides in breast milk, fosters the development of beneficial gut bacteria in infants and protects against pathogens. The formulation also includes both difucosyllactose (DFL) and 3-fucosyllactose (3-FL), two HMOs that are rarely found together in other commercial infant formulas. Nguyen Quang Tri, Chief Marketing Officer of Vinamilk, stated, "Our 6-HMO breakthrough not only raises nutritional standards, but also helps support parents navigating breastfeeding challenges. At Vinamilk, we believe that when parents are happy, a child's development is more complete. We believe this message doesn't just apply to Vietnam – it resonates with millions of parents across Asia." Vinamilk's contribution to the Growth Asia Summit 2025 signals a new chapter in Vietnam's innovation journey. From a country that once had no dairy industry and lagged in nutrition science, Vietnam, through Vinamilk, is stepping into the global spotlight, confidently shaping new standards in pediatric care: proactive, empathetic, and pioneering.
