Physiological needs include: Air, Water, Food, Heat, Clothes, Reproduction, Shelter [22] and Sleep. Many of these physiological needs must be met for the human body to remain in homeostasis. Air, for example, is a physiological need; a human being requires air more urgently than higher-level needs, such as a sense of social belonging.
Behavioral thermoregulation takes precedence over physiological thermoregulation since necessary changes can be affected more quickly and physiological thermoregulation is limited in its capacity to respond to extreme temperatures. [34] When the core temperature falls, the blood supply to the skin is reduced by intense vasoconstriction. [18]
Neuroplasticity is the process by which neurons adapt to a disturbance over time, and most often occurs in response to repeated exposure to stimuli. [27] Aerobic exercise increases the production of neurotrophic factors [note 1] (e.g., BDNF, IGF-1, VEGF) which mediate improvements in cognitive functions and various forms of memory by promoting blood vessel formation in the brain, adult ...
When needs in a category are frustrated, an individual will invest more efforts in the lower category. In 1969, psychologist Clayton Alderfer developed Abraham Maslow 's hierarchy of needs by categorizing the hierarchy into his ERG theory ( Existence , Relatedness and Growth ).
The need for nitrogen is addressed by requirements set for protein, which is composed of nitrogen-containing amino acids. Sulfur is essential, but again does not have a recommended intake. Instead, recommended intakes are identified for the sulfur-containing amino acids methionine and cysteine .
Biochemistry, or biological chemistry, is the study of chemical processes within and relating to living organisms. [1] A sub-discipline of both chemistry and biology, biochemistry may be divided into three fields: structural biology, enzymology, and metabolism.
Biophysical chemistry is a physical science that uses the concepts of physics and physical chemistry for the study of biological systems. [1] The most common feature of the research in this subject is to seek an explanation of the various phenomena in biological systems in terms of either the molecules that make up the system or the supra-molecular structure of these systems.

Physiological condition [1] or, more often "physiological conditions" is a term used in biology, biochemistry, and medicine.It refers to conditions of the external or internal milieu that may occur in nature for that organism or cell system, in contrast to artificial laboratory conditions.
