PlasticsJudith Enck如更坚固的塑料水瓶、婴儿奶瓶和塑料储物容器研究发现，寿司托盘、炊具和其他物品中的黑色塑料含有高浓度的阻燃剂这些有毒化学物质与激素紊乱、生殖并发症和癌症风险升高有关专家指出，对化学物质和微塑料的担忧主耍适用于食物，因为需要吃到肚子里去而重复使用像购物袋这样的一次性塑料则不是大问题专家们一致认为，最重要的是避免让塑料受热“必须严格遵守的一个规则是永远不要用微波炉加热塑料”说，”还有一个建议，如果Enck洗碗机处于高温循环状态，不要把塑料放入洗碗机”如果叫外卖，最好尽快把食物转移到非塑料盘子里，用微波炉加热食物时应该用盘子玻璃和金属水瓶比可重复使用的塑料水瓶更安全，所以当你旅行或出门办事时，一定要随身携带虽然把厨房里所有的塑料都换掉是很理想的，但把重点放在炊具上，选择玻璃或金属的储存容器清洁也有帮助保持家里通风良好，确保定期除尘、拖把和吸尘，也有助于减少环境中有害化学物质的积累第二篇由于担心焦虑情绪的增加和自尊心的下降，即将对青少年使用美颜滤镜实施一系列TikTok的新限制在未来几周，岁以下的用户将无法使用滤镜来人为地放大眼睛、丰满嘴唇，或是18磨皮、改变肤色这些新限制将针对于那些能够以化妆无法做到的方式改变儿童面部特征的滤镜，比如Bold滤镜不过，那些添加兔耳朵或狗鼻子的趣味滤镜则不受影响这家拥有亿用户的Glamour”10社交媒体巨头在其位于都柏林的欧洲总部安全论坛上宣布了这一变动这些限制措施的实施效果，将取决于用户在平台上是否如实填写了自己的真实年龄，而这并非总能得到保证人们普遍担心，无论是官方提供还是用户自制的美颜滤镜，都给青少年，特别是女TikTok孩，带来了巨大的心理压力，迫使他们追求一种完美的外貌，从而产生负面情绪一些年轻人在使用滤镜后表示，自己的真实容貌与滤镜效果相比显得逊色许多宣布将强化其监管系统，禁止岁以下儿童使用该平台，这可能导致数千名英国TikTok13儿童被清退出平台计划在年底前试行新的自动化系统，通过机器学习技术识别试图绕TikTok过年龄限制的用户上述举措与英国《在线安全法》即将于新年生效的更严格未成年人社交媒体使用监管措施相衔接目前，该平台每季度在全球范围内移除约万个未成年账户2000儿童安全公共政策负责人克洛伊•塞特表示“我们希望这些措施能让我们更迅速TikTok地识别并封禁违规用户”对于被误封的用户，他们可以提出申诉塞特承认“这可能会让一些年轻人感到不满，”但她强调，平台将坚持“安全至上”的原则英国通信管理局（）Ofcom在去年月的报告中提到，从年月至年月，大约的1220226202331%英国月活跃用户因年龄过小被平台封禁TikTok监管机构此前曾警告称，的年龄限制执行效果“尚未确定”从明年夏天开始,英TikTok国将严格执行岁以上的社交媒体用户年龄限制，并要求进行“高效”的年龄验证围绕美颜13滤镜和年龄验证的新“保护措施”是社交媒体平台为应对即将生效的更严格法规所宣布的一系列在线安全调整的一部分，违反相关规定的平台可能面临巨额罚款第三篇我们中的许多人都觉得自己太忙了，没有时间锻炼其他人则积极避免锻炼但研究表明，至少做一些运动对于更长寿、更健康的生活很重要，而且不会患上痴呆症、心脏病、糖尿病或癌症其他好处是立竿见影的我们每天都更快乐，更有活力那么，在获得这些好处的同时，你能做多少运动呢？以下是专家的建议:要实现这一目标，首先可能需要改变我们对锻炼的定义世界卫生组织＞美国政府和其他组织的官方指导方针为成年人World HealthOrganization提供了一些选择，告诉他们每周有氧运动的运动量可以达到多低一种选择是进行至少到75150分钟的“剧烈”活动，这意味着你的喘息程度会使谈话变得困难，你的心率会上升到峰值的80%左右另一种选择需要更长的时间，但强度较小到分钟的“适度”运动，心率为最大150300心率的60-70%几十年的研究表明，这些最低限度的运动量可以用最少的汗水换来最大的回报世界卫生组织的流行病学家说“如果你看一下统计曲线，当达到这些最低标准时，收益ReginaGuthold的增加是最显著的”如果你进行更高的运动，比如分钟的适度运动，你会继续获得更大的300健康，但收获会变得更小印第安纳大学医学院心理学家、Indiana UniversitySchool ofmedicine医学副教授玛丽•德•格鲁特说，类似的阈值也有利于心理健康在一项对多Mary deGroot100万人进行的研究中，与每周锻炼到分钟的人相比，那些锻炼更多或更少的人的心理健康120360状况更差但这里有个问题:除了有氧运动，力量训练是必须的，每周不少于两次如果你忽视它，一些年老带来的不良影响可能会等着你，比如肌肉萎缩和骨质疏松症现在，节省时间的漏洞:力量训练可以和有氧运动结合起来通过使用你自己的体重作为阻力而不是更重的杠铃，你可以做更多的重复，在锻炼肌肉的同时提高你的心率指南说，老年人尤其应该关注这种“多成分活动”，包括提高平衡能力以帮助降低跌倒风险的运动为了节省时间，你可以利用这些休息时间中的四到五次作为小型锻炼，每次大约五分钟麦克马斯特大学的运动学教授马丁•吉巴拉说,如果你足够McMaster UniversityMartin Gibala健康，可以加大运动强度，可以尝试一分钟运动，每周次或更多这可能意味着快步走或跑20上一些楼梯，这取决于你的健康水平。
