French fries and hamburgers are popular with teenagers. Everyone knows that these high-calorie foods can lead to chronic illnesses such as heart disease and high blood pressure, but, according to a report published by Medical Xpress, a study led by the University of Queensland in Australia has found that eating too much junk food can also have an impact on teenagers’ sleep quality.
According to the research results, teenagers who drink more than three soft drinks per day were 55 percent more likely to report sleep disturbance than those who only drink one cup per day. Males who ate fast foods on more than four days per week were 55 percent more likely to report sleep disturbance than those who ate them only once a week, while females were 49 percent more likely to do so.
This global study examined unhealthy diets and stress-related sleep disturbance in high school students from 64 countries. The study found that 7.5 percent of adolescents reported having stress-related sleep disturbance, which was more common among females than males and increased with more frequent consumption of carbonated soft drinks, as did the occurrence of sleep problems. Because carbonated drinks often contain caffeine and large amounts of sugar, while fast foods are high in energy but poor in nutrients, long-term consumption can cause nutritional imbalances.

These data were collected from global health surveys conducted by the WHO between 2009 and 2016, which included about 170,000 students aged 12 to 15 years from 64 low, middle and high-income countries in Southeast Asia, Africa, South America and the eastern Mediterranean.
The research team said that frequent intake of soft drinks and eating of fast foods is closely associated with sleep problems in teenagers, and that this phenomenon is particularly clear in high-income countries. The research team said that these findings are worrying because poor-quality sleep has an adverse impact on adolescent health and cognitive development. They suggested that policies should be formulated that target these unhealthy behaviors.

薯條、漢堡等速食及飲料很受青少年喜愛。眾所皆知這些高熱量食物會導致慢性疾病，如心臟病和高血壓等。不過，「醫療快訊」報導，澳洲昆士蘭大學帶領的一項研究發現，吃過多的垃圾食品還會影響青少年的睡眠品質。
根據研究結果，每天喝三杯以上飲料的青少年自稱有睡眠障礙的機率，比每天只喝一杯軟飲料的青少年高百分之五十五。每週吃四天以上速食的男性自稱有睡眠障礙的機率，比那些每週只吃一次速食的男性高百分之五十五，而女性的機率高出百分之四十九。
這是一項針對全球不健康飲食和與壓力有關的睡眠障礙研究，涉及來自六十四個國家的高中生。研究表明，百分之七點五的青少年自稱有壓力相關的睡眠障礙，其中女性比男性更常見，且隨著碳酸飲料的頻繁飲用而增加，睡眠障礙的比率也愈高。因為碳酸飲料通常含有咖啡因和高糖分，而快餐食品高熱量但較缺乏營養，長期攝取會營養不均衡。
這些數據收集自二○○九年至二○一六年世界衛生組織的全球健康調查，其中包括來自東南亞、非洲、南美部分地區和地中東海東部地區的六十四個低、中、高收入國家的約十七萬名十二至十五歲的學生。
研究團隊表示，青少年經常喝飲料、吃速食與睡眠障礙之間關聯密切，這現象尤其在高收入國家特別明顯。研究團隊指出，這些發現令人擔憂，因為睡眠品質差會對青少年的健康和認知發展產生不利影響。他們建議應針對這些不健康的行為制定相關政策，使青少年能健康成長。

An outbreak aboard a cruise ship of a rare rodent-borne illness called hantavirus has left three passengers dead and sickened others, but global health officials say the risk to the general public remains low because the germ does not easily spread between people. “This is not the next COVID, but it is a serious infectious disease,” said Maria Van Kerkhove, director of epidemic and pandemic preparedness at the World Health Organization (WHO). “Most people will never be exposed to this.” The virus usually spreads when people inhale contaminated residue of rodent droppings. Hantaviruses have been around for centuries and are thought to
Have you ever wondered how people navigate the world when they can’t see a map? For individuals with visual impairments, conventional maps are nearly impossible to use. This is where tactile maps come in — essential tools that allow people to “see” the world through touch. A tactile map is specially designed with raised lines, textures, and symbols to represent geographical features such as roads, rivers, and buildings. Users explore it with their fingertips. However, these maps are not exclusively for people with visual disabilities. They serve as valuable multisensory learning tools that enhance spatial understanding for everyone, making

A growing green movement allows hotel guests to fund tree planting projects simply by opting out of daily room cleans. This approach turns an ordinary hotel stay into a direct contribution to nature. Founded in the Netherlands, the nonprofit “Hotels for Trees” operates on the principle that one skipped cleaning equals one new tree. It has planted more than 750,000 trees since 2021. Similarly, Sarnia Hotels in Guernsey donates ￡2 per refused clean. Since 2024, over 3,300 services have been cancelled, raising sufficient money to plant 1,100 native trees and hedgerows. Simplicity has been central to this success.
