Abstract:

A comfortable cabin thermal environment is vital for driver well-being and safety. To establish quantitative guidelines, this study investigated the relationships between physiological signals and subjective thermal perception under realistic vehicular conditions. We collected thermal sensation and comfort votes (TSV/CSV) from a diverse cohort across a range of cabin temperatures, simultaneously measuring five physiological signals: wrist temperature, electrocardiogram, electrodermal activity, electromyogram, and respiration. Our analysis revealed two key findings: 1) Wrist temperature and specific heart rate variability (HRV) metrics showed strong correlations with both cabin temperature and subjective votes, delineating the physiological basis of thermal comfort. 2) We empirically determined the thermal neutral temperature to be 26.2 °C, with the optimal comfort zone spanning from 23.4 °C to 28.3 °C. These results provide car manufacturers with direct, data-driven evidence for defining occupant-centric climate control setpoints and developing future comfort assessment systems based on physiological feedback.

Requirements for Human Life

Requirements for Human Life

The Earth and its atmosphere have provided humans with air, water, and food, but these are not the only requirements for survival. Humans also require a specific range of temperature and pressure that the Earth and its atmosphere provides.
Oxygen
Atmospheric air is only about 20 percent oxygen, but that oxygen is a key component of the chemical reactions that keep the body alive, including the reactions that produce ATP. Brain cells are susceptible to a lack of oxygen because they require a...

Factors Affecting Body Temperature

Factors Affecting Body Temperature

As a nurse, it is vital to understand the factors affecting body temperature to monitor variations and effectively evaluate deviations from regular.
Factors may include:

Responses to Heat and Cold Stress

Responses to Heat and Cold Stress

Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.

Body Temperature

Body Temperature

The body's temperature, measured in degrees, is determined by the balance between heat production and dissipation to the surrounding environment. For instance, if exercising vigorously, the body will produce more heat, causing sweat and dissipating that heat. Despite extreme environmental conditions and physical exertion, the human temperature-control system maintains a constant core body temperature (the temperature of deep tissues, which are the tissues located beneath the skin and other...

Body Temperature

Body Temperature

Body temperature reflects the equilibrium between heat production and heat loss within the body. Most heat is generated by metabolically active tissues, particularly the liver, heart, brain, kidneys, and endocrine organs. At rest, skeletal muscles contribute 20–30% of total heat production, but during vigorous exercise, this can increase up to 30–40 times.
The average body temperature is approximately 37°C (98.6°F) and typically ranges from 36.1–37.2°C...

Temperature and Thermal Equilibrium

Temperature and Thermal Equilibrium

Heat and temperature are essential concepts for everyone every day. The study of heat and temperature is part of an area of physics known as thermodynamics. It is not always easy to distinguish heat and temperature.
The concept of temperature has evolved from the common concepts of hot and cold. The scientific definition of temperature explains more than just our sense of hot and cold. Temperature is operationally defined as the quantity measured with a thermometer. Furthermore, temperature is...
