People looking for ways to increase their life expectancy should start by exercising regularly, the Health Promotion Administration said yesterday, citing a study showing that exercising for 15 minutes per day can add an average of three years to a person’s life.
Health Promotion Administration Director-General Chiu Shu-ti (邱淑媞) made the remarks at a press conference in Taipei, as the agency released a new version of an exercise guidebook to promote the benefits of regular exercise.
“Most people have difficulty adhering to the widely adopted physical guidelines for adults, which require them to exercise for at least 30 minutes a day, five days a week,” Chiu said.
However, under the agency’s new exercise guideline, people only have to work out 15 minutes a day or 90 minutes a week to get healthier and see their risk of dying from a variety of diseases greatly reduced, Chiu said.
The new guidelines are based on the results of a 2011 study conducted by National Health Research Institutes researcher Wen Chi-pang (溫啟邦).
The study monitored the health of about 416,000 Taiwanese who participated in a standard medical screening program from 1996 to 2008 for an average of eight years, and who were divided into five groups: inactive, low, medium, high or very high exercise activity.
Compared with inactive participants, the study found that people in the low activity group who speed-walked 15 minutes every day over eight years enjoyed a three-year longer life expectancy, a 14 percent reduced risk of all-cause mortality and a 10 percent lowered chance of dying from cancer.
Those who exercised for an additional 15 minutes per day saw their lifespan further increased by one year, the study showed.
“Not only can people who keep doing this [speed-walking] everyday, for about 90 minutes a week, live three years longer, but they can also greatly lower their risk of dying or developing cancer, heart disease, diabetes and many other diseases,” Wen said.
However, Wen added that only physical activities that were done “on purpose” could achieve such effects.
Chiu said that exercise is a great equalizer because everyone receives the same health benefits regardless of their financial status.
“Those who are willing to exercise are rewarded with the most valuable asset — health. On the other hand, those who do not do so increase their chances of developing breast or colorectal cancer by 25 percent, diabetes by 27 percent and ischemic heart disease by 30 percent,” Chiu said.
The military has spotted two Chinese warships operating in waters near Penghu County in the Taiwan Strait and sent its own naval and air forces to monitor the vessels, the Ministry of National Defense (MND) said. Beijing sends warships and warplanes into the waters and skies around Taiwan on an almost daily basis, drawing condemnation from Taipei. While the ministry offers daily updates on the locations of Chinese military aircraft, it only rarely gives details of where Chinese warships are operating, generally only when it detects aircraft carriers, as happened last week. A Chinese destroyer and a frigate entered waters to the southwest
The eastern extension of the Taipei MRT Red Line could begin operations as early as late June, the Taipei Department of Rapid Transit Systems said yesterday. Taipei Rapid Transit Corp said it is considering offering one month of free rides on the new section to mark its opening. Construction progress on the 1.4km extension, which is to run from the current terminal Xiangshan Station to a new eastern terminal, Guangci/Fengtian Temple Station, was 90.6 percent complete by the end of last month, the department said in a report to the Taipei City Council's Transportation Committee. While construction began in October 2016 with an
NON-RED SUPPLY: Boosting the nation’s drone industry is becoming increasingly urgent as China’s UAV dominance could become an issue in a crisis, an analyst said Taiwan’s drone exports to Europe grew 41.7-fold from 2024 to last year, with demand from Ukraine’s fight against Russian aggression the most likely driver of growth, a study showed. The Institute for Democracy, Society and Emerging Technology (DSET) in a statement on Wednesday said it found that many of Taiwan’s uncrewed aerial vehicle (UAV) sales were from Poland and the Czech Republic. These countries likely transferred the drones to Ukraine to aid it in its fight against the Russian invasion that started in 2022, it said. Despite the gains, Taiwan is not the dominant drone exporter to these markets, ranking second and fourth
Japanese Prime Minister Sanae Takaichi’s comment last year on Tokyo’s potential reaction to a Taiwan-China conflict has forced Beijing to rewrite its invasion plans, a retired Japanese general said. Takaichi told the Diet on Nov. 7 last year that a Chinese naval blockade or military attack on Taiwan could constitute a “survival-threatening situation” for Japan, potentially allowing Tokyo to exercise its right to collective self-defense. Former Japan Ground Self-Defense Force general Kiyofumi Ogawa said in a recent speech that the remark has been interpreted as meaning Japan could intervene in the early stages of a Taiwan Strait conflict, undermining China’s previous assumptions
