Contentment in the context of "Joy"

Inner peace (also known as peace of mind) refers to a deliberate state of psychological or spiritual calm maintained despite the presence of stressors. It is associated with a state of psychological "homeostasis" and the opposite of being stressed or anxious, and is considered to be a state where one's mind performs at an optimal level, regardless of outcomes. Peace of mind is thus generally associated with a state of contentment and emotional well-being including bliss, happiness and contentment.

Peace of mind, serenity, and calmness are descriptions of a disposition free from the effects of stress. In various cultural traditions, inner peace is regarded as a state of consciousness attainable through practices such as breathing exercises, prayer, meditation, tai chi or yoga. Many spiritual practices refer to this peace as an experience of knowing oneself.

Joy is the state of being that allows one to experience feelings of intense, long-lasting happiness and contentment of life. It is closely related to, and often evoked by, well-being, success, or good fortune. Happiness, pleasure, and gratitude are closely related to joy but are not identical to it.

Thermal comfort is the condition of mind that expresses subjective satisfaction with the thermal environment. The human body can be viewed as a heat engine where food is the input energy. The human body will release excess heat into the environment, so the body can continue to operate. The heat transfer is proportional to temperature difference. In cold environments, the body loses more heat to the environment and in hot environments the body does not release enough heat. Both the hot and cold scenarios lead to discomfort. Maintaining this standard of thermal comfort for occupants of buildings or other enclosures is one of the important goals of HVAC (heating, ventilation, and air conditioning) design engineers.

Thermal neutrality is maintained when the heat generated by human metabolism is allowed to dissipate, thus maintaining thermal equilibrium with the surroundings. The main factors that influence thermal neutrality are those that determine heat gain and loss, namely metabolic rate, clothing insulation, air temperature, mean radiant temperature, air speed and relative humidity. Psychological parameters, such as individual expectations, and physiological parameters also affect thermal neutrality. Neutral temperature is the temperature that can lead to thermal neutrality and it may vary greatly between individuals and depending on factors such as activity level, clothing, and humidity. People are highly sensitive to even small differences in environmental temperature. At 24 °C (75.2 °F), a difference of 0.38 °C (0.684 °F) can be detected between the temperature of two rooms.

Customer satisfaction is a term frequently used in marketing to evaluate customer experience. It is a measure of how products and services supplied by a company meet or surpass customer expectation. Customer satisfaction is defined as "the number of customers, or percentage of total customers, whose reported experience with a firm, its products, or its services (ratings) exceeds specified satisfaction goals". Enhancing customer satisfaction and fostering customer loyalty are pivotal for businesses, given the significant importance of improving the balance between customer attitudes before and after the consumption process.

Expectancy disconfirmation theory is the most widely accepted theoretical framework for explaining customer satisfaction. However, other frameworks, such as equity theory, attribution theory, contrast theory, assimilation theory, and various others, are also used to gain insights into customer satisfaction. However, traditionally applied satisfaction surveys are influence by biases related to social desirability, availability heuristics, memory limitations, respondents' mood while answering questions, as well as affective, unconscious, and dynamic nature of customer experience.
