Facing an especially cold winter this year, many people are attempting to stay warm by taking long, hot showers or baths, a practice that could increase the risks of cancer if done in an enclosed space, doctors said yesterday.
While many people enjoy taking a hot bath or shower, few are aware of the health risks associated with the activity, they said.
Chiang Shou-shan (江守山), a nephrologist at Shin-Kong Wu Ho-Su Memorial Hospital, said taking long, hot showers or baths for more than 20 minutes in a confined space with no circulation of fresh air could have a negative impact on a person’s health, because small amounts of chlorine and trihalomethanes (THM) found in tap and drinking water become volatile when the water is heated.
The chemicals can enter the body through the respiratory -system as a person breathes in the steam, Chiang said.
The longer the hot shower, the more THMs a person inhales, Chiang said.
Increasing shower time from five minutes to 10 minutes, for example, could cause a person to breathe in four to five times more THMs, he said.
THM is a byproduct of the small amount of chlorine added to the water supply by municipal authorities as a disinfectant. However, overexposure to THMs can increase the risks of developing various forms of cancer, including colon cancer, pancreatic cancer and bladder cancer.
The chemicals are also harmful to the liver and kidneys, and could increase the risks of miscarriage in women, he said.
Lin Ja-liang (林杰樑), a specialist in clinical toxicology at Chang Gung Memorial Hospital in New Taipei City’s (新北市) Linkou District (林口), said that by limiting hot showers to less than 10 minutes and reducing the temperature of the water, a person could drastically decrease the amount of THMs absorbed by the body.
Turning on the fan in the bathroom to allow for air circulation was also a good way to avoid breathing in too many toxins from a steamy shower, he said.
Taiwan is to commence mass production of the Tien Kung (天弓, “Sky Bow”) III, IV and V missiles by the second quarter of this year if the legislature approves the government’s NT$1.25 trillion (US$39.78 billion) special defense budget, an official said yesterday. Commenting on condition of anonymity, a defense official with knowledge of the matter said that the advanced systems are expected to provide crucial capabilities against ballistic and cruise missiles for the proposed “T-Dome,” an advanced, multi-layered air defense network. The Tien Kung III is an air defense missile with a maximum interception altitude of 35km. The Tien Kung IV and V
The disruption of 941 flights in and out of Taiwan due to China’s large-scale military exercises was no accident, but rather the result of a “quasi-blockade” used to simulate creating the air and sea routes needed for an amphibious landing, a military expert said. The disruptions occurred on Tuesday and lasted about 10 hours as China conducted live-fire drills in the Taiwan Strait. The Civil Aviation Administration (CAA) said the exercises affected 857 international flights and 84 domestic flights, affecting more than 100,000 travelers. Su Tzu-yun (蘇紫雲), a research fellow at the government-sponsored Institute for National Defense and Security Research, said the air
Trips for more than 100,000 international and domestic air travelers could be disrupted as China launches a military exercise around Taiwan today, Taiwan’s Civil Aviation Administration (CAA) said yesterday. The exercise could affect nearly 900 flights scheduled to enter the Taipei Flight Information Region (FIR) during the exercise window, it added. A notice issued by the Chinese Civil Aviation Administration showed there would be seven temporary zones around the Taiwan Strait which would be used for live-fire exercises, lasting from 8am to 6pm today. All aircraft are prohibited from entering during exercise, it says. Taipei FIR has 14 international air routes and
Taiwan lacks effective and cost-efficient armaments to intercept rockets, making the planned “T-Dome” interception system necessary, two experts said on Tuesday. The concerns were raised after China’s military fired two waves of rockets during live-fire drills around Taiwan on Tuesday, part of two-day exercises code-named “Justice Mission 2025.” The first wave involved 17 rockets launched at 9am from Pingtan in China’s Fujian Province, according to Lieutenant General Hsieh Jih-sheng (謝日升) of the Office of the Deputy Chief of the General Staff for Intelligence at the Ministry of National Defense. Those rockets landed 70 nautical miles (129.6km) northeast of Keelung without flying over Taiwan,
