Nearly 80 percent of students in Taiwan get less than eight hours of sleep per night, a survey released yesterday by the Child Welfare League Foundation showed.
The survey, which looked at sleeping habits and the use of stimulant drinks among junior, senior and vocational high-school students, found that respondents got an average of 6.9 hours of sleep each night.
Overall, students go to bed at 11:15pm and wake up at 6:12am, the foundation said.

Junior-high school students reported an average of 7.3 hours of sleep per night, while students in senior or vocational high schools reported 6.5 hours, the survey found.
Among the latter, 88.9 percent said they slept less than eight hours a night, and 23.7 percent said they slept less than six hours, the survey found.
Asked why they stayed up late the last time, 33.6 percent of respondents said it was to read, do their homework or prepare for a test, 22.6 percent said “screen time” and 21 percent said they either had trouble falling asleep or were in a bad mood.
One-quarter of respondents who reported averaging seven or less hours of sleep said they “often” or “always” doze off in class, while the same was true for 12.7 percent of those who reported more than seven hours of sleep, the foundation said.
Nearly 52 percent of respondents who slept seven hours or less said they felt exhausted after a day of classes, including after-school instruction, while 32.6 percent of those who slept more than seven hours said that was the case, the survey found.
In addition, 68.6 percent of respondents reported drinking an energy drink or coffee in the past month, while 35.1 percent of respondents who drank more than one cup of coffee per week had trouble with sleep, the foundation said.
Children aged 13 to 18 should be getting eight to 10 hours of sleep, foundation executive secretary Huang Yun-shan (黃韻璇) said.
Lack of sleep can lead to tiredness during the day, reduce a person’s concentration and affect their mood, said Frank Lu (呂立), director of the pediatric pulmonary and critical care medicine department at National Taiwan University Children’s Hospital.
People who have trouble sleeping should try to keep a regular sleeping schedule, exercise during the day and avoid stimulating activities before bedtime, such as looking at their phones, he said.
The survey was conducted via paper questionnaires from Sept. 16 to Oct. 31 last year, and 1,536 valid samples were collected, the foundation said, adding that the survey had a margin of error of 2.5 percentage points.
LOUD AND PROUD Taiwan might have taken a drubbing against Australia and Japan, but you might not know it from the enthusiasm and numbers of the fans Taiwan might not be expected to win the World Baseball Classic (WBC) but their fans are making their presence felt in Tokyo, with tens of thousands decked out in the team’s blue, blowing horns and singing songs. Taiwanese fans have packed out the Tokyo Dome for all three of their games so far and even threatened to drown out home team supporters when their team played Japan on Friday. They blew trumpets, chanted for their favorite players and had their own cheerleading squad who dance on a stage during the game. The team struggled to match that exuberance on the field, with
Taiwanese paleontologists have discovered fossil evidence that pythons up to 4m long inhabited Taiwan during the Pleistocene epoch, reporting their findings in the international scientific journal Historical Biology. National Taiwan University (NTU) Institute of Ecology and Evolutionary Biology associate professor Tsai Cheng-hsiu (蔡政修) led the team that discovered the largest snake fossil ever found in Taiwan. The single trunk vertebra was discovered in Tainan at the Chiting Formation, dated to between 400,000 and 800,000 years ago in the Middle Pleistocene, the paper said. The area also produced Taiwan’s first avian fossil, as well as crocodile, mammoth, saber-toothed cat and rhinoceros fossils, it said. Discoveries

Whether Japan would help defend Taiwan in case of a cross-strait conflict would depend on the US and the extent to which Japan would be allowed to act under the US-Japan Security Treaty, former Japanese minister of defense Satoshi Morimoto said. As China has not given up on the idea of invading Taiwan by force, to what extent Japan could support US military action would hinge on Washington’s intention and its negotiation with Tokyo, Morimoto said in an interview with the Liberty Times (sister paper of the Taipei Times) yesterday. There has to be sufficient mutual recognition of how Japan could provide
