The Health Promotion Administration (HPA) yesterday said that 190 people sought treatment for heat injuries at hospital emergency rooms (ERs) in the first 10 days of this month, and that not all of the injuries occurred outdoors.
Outdoor temperatures have on most days recently reached 35°C, and sometimes topped 37°C, resulting in a rise in heat injuries, it said, citing Central Weather Bureau statistics.
The types of injury are heat cramps, heat exhaustion and heat stroke, it said.

From July 1 to Friday, there were 190 ER visits for heat injuries, up from 116 visits a year earlier, or about 1.6 times higher, the HPA said, adding that not all of the cases occurred under a scorching sun.
The main cause of indoor heat injuries is poor ventilation, which causes the indoor temperature to rise rapidly, HPA Community Health Division head Lo Su-ying (羅素英) said, adding that heat injuries develop if people’s bodies are not regulating their temperature properly.
“Elderly people and children are usually less capable of regulating their body temperature, so they are more susceptible to oversweating and dehydration if room temperatures continue to rise, and they might have a heat injury,” she said.
In hot weather, people should drink water more frequently, not just when they feel thirsty, and avoid drinking alcohol or sugary beverages, the HPA said, adding that air-conditioners should be set at about 26°C or 27°C, or rooms should have good ventilation.
Wearing a thin jacket in air-conditioned buildings can prevent discomfort from sudden changes between indoor and outdoor temperatures, while wearing lightweight and loose-fitting clothing permits greater air circulation and evaporation of sweat, allowing the body to cool faster, it said.
Heat injury symptoms include rising body temperature, flushed skin, a rapid heartbeat, headache, dizziness, vomiting, weakness, cramps and confusion, Lo said.
Excessive heat can even cause a seizure or coma, Lo added.
People with symptoms should move to a cool place and try to lower their body temperature by removing excess clothing, drenching the skin with cool water or fanning the skin.
They should drink cool water with salt or an electrolyte drink, and be taken for medical treatment as soon as possible.
EXCUSES: Beijing is using government and research vessels as a pretext to harass the nation and enter its EEZ, and engage in ‘hegemonic expansion,’ the coast guard said The Coast Guard Administration yesterday said it drove away Chinese oceanographic research vessel Xiang Yang Hong 22 (向陽紅33) from restricted waters after warning it that it was in Taiwan’s exclusive economic zone (EEZ). The Chinese vessel entered restricted waters off the coast of Yilan County’s Suao (蘇澳) at 11:35pm on Thursday, the coast guard said, adding that it dispatched the Lanyu patrol vessel and the boat PP-10077 to shadow the Chinese ship and issue radio warnings ordering it to leave. China has no sovereignty over waters off Taiwan’s east coast, Lanyu’s crew told Xiang Yang Hong 22 over the radio, and demanded
BAIT AND SWITCH: Allowing KMT-run counties to sell to China while the threat of abrupt cancelations hangs overhead is another form of coercion, officials said Beijing is using agricultural purchase offers announced during the Straits Forum to deepen Taiwan’s dependence on the Chinese market, a Taiwanese official said yesterday as they criticized the Taitung County commissioner’s participation in the initiative. During the Straits Forum held in Xiamen on Saturday, Chinese officials announced a sales and purchase agreement for agricultural products from some counties led by the Chinese Nationalist Party (KMT). Taitung County Commissioner Yao Ching-ling (饒慶鈴), who was barred from attending the event in person by the Mainland Affairs Council, participated via video. Under the agreement, China would purchase atemoyas, pomeloes, tea and grouper harvested in Taitung,
SHIFTING FIRE: While the tempo of purely military exercises around Taiwan has gone down somewhat, Beijing is working to isolate Lai diplomatically from support abroad Chinese President Xi Jinping (習近平) is shifting tactics in his campaign to pressure Taiwan, ramping up diplomatic isolation of the nation while dialing down provocative displays of military aggression. Taiwan recorded a daily average of five Chinese military aircraft crossing the Taiwan Strait’s buffer line with China through May this year — half the number logged in the same period last year. In March, Beijing did not send a single fighter jet near Taiwan for seven days, the longest absence on record outside of typhoon season. In comparison, China sent 153 planes near Taiwan during one day at its peak in
