Higher temperatures increase the risk of premature delivery during the later stages of pregnancy, according to research conducted in Taiwan.
The work was part of a research project conducted by a team led by Taipei Medical University College of Public Health dean Chen Yi-hua (陳怡樺) and was presented at a seminar on Saturday on climate change’s impact on pregnancies.
It integrated cohort studies from 2011 to 2022 in Taipei and New Taipei City, and weather data from the Central Weather Administration to analyze the influence of high temperatures on fetuses.

The research showed that for a woman who falls pregnant in the winter (and gives birth in the summer), the higher nighttime temperatures she is exposed to in late pregnancy have a negative impact on her and the child’s health.
Every 1°C increase in the average temperature raises the risk of premature birth and low birth weight by 6 percent.
For the mother, higher temperatures lead to higher rates of depression.
Taipei Medical University College of Public Health vice dean Chao Hsing (趙馨) said that there are many mechanisms linking antepartum depression and premature birth.
Heat can lead to negative emotions and increase the risk of premature birth, Chao said.
Lee Hung-chang (李宏昌), an honorary physician at Mackay Children’s Hospital, said that pregnant women and children are vulnerable to extreme temperatures.
The research also showed that exposure to green spaces during pregnancy is significantly correlated to the development of a child’s ability to concentrate.
Chao called on pregnant women to take walks in green spaces, as well as enhance their knowledge of heat risks and take necessary precautions.
She said she hoped authorities would devote more resources to green spaces to protect vulnerable groups against climate change.
A relatively large earthquake may strike within the next two weeks, following a magnitude 5.2 temblor that shook Taitung County this morning, the Central Weather Administration (CWA) said. An earthquake struck at 8:18am today 10.2km west of Taitung County Hall in Taitung City at a relatively shallow depth of 6.5km, CWA data showed. The largest intensity of 4 was felt in Taitung and Pingtung counties, which received an alert notice, while areas north of Taichung did not feel any shaking, the CWA said. The earthquake was the result of the collision between the Philippine Plate and the Eurasian Plate, the agency said, adding

HOLIDAY EXERCISE: National forest recreation areas from north to south offer travelers a wide choice of sights to connect with nature and enjoy its benefits Hiking is a good way to improve one’s health, the Forestry and Nature Conservation Agency said, as it released a list of national forest recreation areas that travelers can visit during the Lunar New Year holiday. Taking a green shower of phytoncides in the woods could boost one’s immunity system and metabolism, agency Director-General Lin Hwa-ching (林華慶) cited a Japanese study as saying. For people visiting northern Taiwan, Lin recommended the Dongyanshan National Forest Recreation Area in Taoyuan’s Fusing District (復興). Once an important plantation in the north, Dongyanshan (東眼山) has a number of historic monuments, he said. The area is broadly covered by
Global bodies should stop excluding Taiwan for political reasons, President William Lai (賴清德) told Pope Francis in a letter, adding that he agrees war has no winners. The Vatican is one of only 12 countries to retain formal diplomatic ties with Taiwan, and Taipei has watched with concern efforts by Beijing and the Holy See to improve ties. In October, the Vatican and China extended an accord on the appointment of Catholic bishops in China for four years, pointing to a new level of trust between the two parties.
