  宿舍室内温度比较高,一般只穿单衣”。调查显示,影响受访者穿衣厚度的主要因素是气温高低(66.6%)和所处季节(53.3%),接下来依次是:是否美观(25.2%)、俗语等相关知识(15.7%)和家人要求(14.2%)等,6.6%的受访者表示自己会随大流增减衣物。当下,一些年轻人为了美观,即使在很冷的天气也只穿着轻薄的衣物,对于这种做法,47.2%的受访者认为有碍健康,不应该为了美丽而选择“冻人”;20.5%的受访者认为虽然不利于健康,但是影响不大;20.5%的受访者感觉无所谓,是个人的选择;5.8%的受访者认为无可厚非,美观同样很重要;5.4%的受访者认为只要在室外时间不长,应该不会对健康造成很大危害。徐晶认为,一些年轻人不爱穿秋衣秋裤,一方面可能是感觉不方便,另一方面可能会觉得厚厚的,不美观。

近日,国家卫生健康委办公厅印发了《健康口腔行动方案(2019—2025年)》,提出在有咀嚼槟榔习惯的地区,以长期咀嚼槟榔对口腔健康的危害为重点,针对性地开展宣传教育和口腔健康检查,促进牙周、口腔黏膜病变等疾病早诊早治。 专家表示,长期咀嚼槟榔有患口腔癌的风险。

国家食品药品监督管理总局在2017年公布致癌物清单时,已将槟榔果列入一级致癌物。 北京大学口腔医院口腔黏膜科教授、中华口腔医学会副秘书长刘宏伟表示,我国南方一些省份的群众有咀嚼槟榔的习惯,从而导致了口腔癌的发病率增高。

前期槟榔碱先逐渐导致口腔黏膜纤维化,患者会有张口受限、舌活动受限、黏膜弹性丧失及溃烂等表现,也有疼痛、影响进食等痛苦。

这是口腔癌发生前的癌前病变。

且槟榔成瘾性强,时间久了可以转化为口腔癌。 在国内咀嚼槟榔盛行的地区如海南省、湖南省等地,绝大多数的口腔癌是由咀嚼槟榔导致的。

2018年中华口腔医学会和中国疾控中心曾调研湖南省群众嚼槟榔和口腔癌的现状,当时中南大学湘雅医院口腔颌面外科病房内,50位住院患者有45人患口腔癌,其中44人有长期、大量咀嚼槟榔病史。 刘宏伟说,槟榔嚼物一般由槟榔果、老花藤和煅石灰组成,有的地区还在其中掺加一些烤烟和香料。

其中的添加剂如石灰、丁香、烟叶和槟榔籽中含有一些致癌因子,口腔癌的发生与嚼槟榔的时间和槟榔在口腔内滞留的时间呈正比。
