Abstract

Global warming has raised significant concerns about mitigation and adaptation strategies in recent years. This study investigated if consuming spicy food can help improve people’s adaptability to hot environment. Onsite measurement and thermal questionnaires were conducted at Chongqing university in summer and winter aged 18 ∼ 30 years old. Participants were categorized into two groups, including frequently eating hotpot (Group-yes) and not (Group-no), and there were respectively 590 and 570 surveys. The results indicated that: (1) Eating hotpot could lower expectations of meteorological conditions. (2) It can decrease thermal sensitivity and expand neutral physiologically equivalent temperature (PET) range (14.89 ∼ 24.74 ℃ in Group-yes and 16.66 ∼ 23.98 ℃ in Group-no). (3) The acceptable PET range in Group-yes was 5.46 ℃ wider than Group-no with a higher preferred PET in Group-yes (24.04 ℃) compared to Group-no (22.63 ℃). (4) Respondents’ thermal perception in Group-yes demonstrated a less susceptibility to meteorological variations compared to Group-no, and respondents in Group-no were more influenced by RH in summer. These findings suggest that consuming hotpot can improve thermal adaptation, thereby underscoring the significant influence of dietary habits on thermal adaptability.

饮食习惯有助于提高人们对炎热气候的适应性：以中国重庆的火锅为例。

近年来，全球变暖引起了人们对减缓和适应战略的重大关切。本研究调查食用辛辣食物是否有助于提高人们对热环境的适应能力。研究人员于夏季和冬季在重庆大学对18 ~ 30岁的学生进行了现场测量和热问卷调查。参与者被分为两组，一组经常吃火锅，另一组不吃火锅，分别有590份和570份调查。结果表明：(1)吃火锅会降低气象条件的预期。(2)能降低热敏性，扩大中性生理等效温度（PET）范围（Group-yes为14.89 ~ 24.74℃，Group-no为16.66 ~ 23.98℃）。(3) Group-yes的PET可接受范围比Group-no宽5.46℃，Group-yes的PET可接受范围（24.04℃）比Group-no的PET可接受范围（22.63℃）高。(4)“是”组的热感知受气象变化的敏感性较“否”组低，“否”组受夏季湿度的影响更大。综上所述，食用火锅可以提高热适应能力，从而强调了饮食习惯对热适应的显著影响。

期刊介绍： The Journal publishes original research papers, review articles and short communications on studies examining the interactions between living organisms and factors of the natural and artificial atmospheric environment. Living organisms extend from single cell organisms, to plants and animals, including humans. The atmospheric environment includes climate and weather, electromagnetic radiation, and chemical and biological pollutants. The journal embraces basic and applied research and practical aspects such as living conditions, agriculture, forestry, and health. The journal is published for the International Society of Biometeorology, and most membership categories include a subscription to the Journal.
