Effects of Age, Gender and Body Mass Index on Reaction to Air Condition/EFFETS DE L'ÂGE, DU SEXE ET DE L'INDICE DE MASSE CORPORELLE SUR LA RÉACTION DES GENS ENVERS L'AIR CLIMATISÉ

Article excerpt

Abstract:

This study investigated the effect of age, gender, and body mass index (BMI) on reaction to air condition. Forty eight undergraduates (21 males and 27 females) randomly selected from Imo State University, Owerri, Nigeria within the age range of 17-30 years participated in the study. 26 of them were of normal weight (BMI <23) and 22 were over-weight (BMI >24). They were exposed to an air conditioned room for two hours and then their reaction to cold measured using Response to Cold questionnaire. Employing t-test and ANOVA for data analyses, the results showed that body size, age, and gender had no statistically significant effect on reaction to cold condition while exposure to cold condition had a significant influence on both systolic and diastolic blood pressures of all participants.

Key words: Body mass index; Air condition; Reaction; Blood pressure; Systolic blood pressure; Diastolic blood pressure; Cold

Resume: Cette étude a examiné l'effet de l'âge, du sexe et de l'indice de masse corporelle (IMC) sur la réaction des gens envers l'air climatisé. Quarante-huit étudiants de premier cycle (21 hommes et 27 femmes) sélectionnés au hasard dans l'Université de Tétât d'Imo à Owerri au Nigeria dans une tranche d'âge de 17 ans à 30 ans ont participé à cette étude. 26 d'entre eux avaient un poids normal (IMC <23) et 22 sont en surpoids (IMC> 24). Ils ont été exposés dans une salle climatisée pour deux heures, puis leur réaction au froid a été mesuré en utilisant le questionnaire de Réponse au froid. Après le t-test et une analyse de variance des données, les résultats ont montré que la taille corporelle, l'âge et le sexe n'avaient aucun d'effet statistiquement significatif sur la réaction à l'état froid, tandis que l'exposition à l'état froid avait une influence significative sur les pressions artérielles systoliques et diastoliques de tous les participants.

1. INTRODUCTION

Humans interact with their environment leading to various behaviours. The outcome of such interaction is often dependent upon certain human attributes such as gender, age, social and marital statuses, educational levels, personality types, body sizes/types/weight etc. The degree of these variations sometimes, remains blurred and makes us wonder if human beings react the same way in certain settings.

Since behaviour is biologically and environmentally driven, the interaction of the two is always necessary in measuring behaviour. The study of genetics by Gregor Mendel in 1865 has led to the understanding of inheritance (Liu, 2006), which is like a foundation the environment builds on. "Nature makes the boy toward, nurture sees him forward" (Mulcaster, 1582). In this same vein, internal body environment helps regulate behaviour like we feel hungry and are motivated to seek food to create balance.

When it comes to temperature regulation and homeostasis, how does the hotness and coldness of the environment affect individuals; direct their behaviour and show differences in their reaction, across gender and body size? The researchers wonder if the condition of the physical environment of humans influences them physiologically and how it determines their reaction/ behavior in various settings.

Physiological gender differences have always instigated research for they lead to the understanding of certain patterns of gender-related behaviours. According to Marina (2008), in comparison to men, it is true women naturally are prone to carrying more fat. The presence of fat helps insulate the body and keeps it warm, and hence women tend to be warmer in cold environment than their male counterparts. But Raynaud's disease, which causes the blood vessels in the hands and feet to overreact to cold or stress, is more common in women than in men, and studies are being done to see if it is an inherited condition (Cedars-Sinai Health System, 2007). …
