The Himalayas are considered highly vulnerable to climate change, and hence making adaptation strategies for the area to cope with the effects of climate change is crucial. These strategies should be developed and implemented with grassroots participation at local to regional levels. For informed participation, the local inhabitants need to be conscious of climate change and its implications. Hence, we explored the level of awareness among school students and their participation in actions...

Ten healthy young adults slept one by one in a specially designed and constructed sleep capsule located in a climate chamber at two temperatures (24 °C and 28 °C) and two ventilation rates that ensured that the resulting CO2 concentrations were 800 and 1700 ppm. Subjectively rated sleep quality was reduced at 28 °C and reduced ventilation, while sleep onset latency was longer under these conditions. Sleep efficiency was lower at 28 °C. Subjectively rated fatigue and sleepiness decreased...

Heat stress-related illness attributed to the changing climate, particularly the more frequent extreme high temperatures, is becoming a theme of public concern, especially in the most vulnerable regions, such as the African continent. Knowledge of the existing research directions and gaps on heat stress and human health is vital for informing future strategic research foci capable of influencing policy development, planning, adaptation, and mitigation efforts. In this regard, a bibliometric...

Abstract Climate change presents significant threats to human health, especially for low-income urban communities in the Global South. Despite numerous studies of heat stress, surprisingly little is known about the temperatures actually encountered by people in their homes, or the benefits of affordable adaptations. This paper examines indoor air temperature measurements gathered from 47 living rooms within eight low-income communities of Accra and Tamale, Ghana. Using multiple...

This study managed to create thermal comfort conditions at three temperatures (24°C-T24, 26°C-T26, and 28°C-T28) by adjusting clothing and air velocity. Thirty- six subjects (18 males and 18 females) were exposed to each of the three conditions for 4.5 h in a design balanced for order of presentation of conditions. During each exposure, they rated the physical environment, their comfort, the intensity of acute subclinical health symptoms, and their mental load, and they performed a...

This study investigated whether adjusting clothing to remain in neutral thermal comfort at moderately elevated temperature is capable of avoiding negative effects on perceived acute subclinical health symptoms, comfort, and cognitive performance. Two temperatures were examined: 23°C and 27°C. Twelve subjects were able to remain thermally comfortable at both temperatures by adjusting their clothing. They rated the physical environment, their comfort, the intensity of acute subclinical health...

Information has a significant role in the growth of people and societies. Yet access to information is unequal across communities, particularly in rural areas in developing countries. Given this, people’s consciousness of climatic change differs by several factors including location and the type of medium employed. This paper examines community information centres as a vehicle for climate change awareness creation in Ghana. The paper adopted a quantitative approach with 205 participants...

Despite their impact on work performance, cognitive responses to thermal variations in buildings have not been accurately quantified. Practical limitations in individual laboratory experiments with limited participants often cause low statistical power and restrict generalizability. Thus, inconsistencies in individual studies motivate summary reviews and meta-analyses. The objective of this study is to estimate the correlation between ambient air temperature and cognitive performance through...

A two-week-long intervention study was performed in two classrooms in an elementary school in Costa Rica. Split-cooling air-conditioning (AC) units were installed in both classrooms. During the first week, the air temperature was reduced in one classroom while in the other (placebo) classroom the fans were operated but no cooling was provided. During the second week, the conditions were exchanged to create a 2 × 2 crossover design in which each pupil was their own control. A total of 37...

The Tamil Nadu government actively supports farmer development through frequent training programs. These programs, incorporating both classroom sessions and field visits, are targeted towards farmer members of Farmer Producer Organizations (FPOs) and conducted at regular intervals. Recognizing the importance of understanding farmers' motivations and preferences, the training centers conducted a study involving 80 FPO farmer respondents from Coimbatore and Nilgiris districts. Using rank-based...

In this article, a simple approach to modeling heat transfer between the outside environment to a location inside a building is used to precisely predict indoor temperatures for a large range of historical dates. The data collection, statistical modeling and prediction of inside temperature based on available weather data obtained outside the building of interest are presented. An initial simple linear regression model estimates the heat transfer mechanism between outside and inside which is...
