Relaxation stands quite generally for a release of tension, a return to equilibrium.
In the sciences, the term is used in the following ways:
- Relaxation (physics), and more in particular:
- Relaxation (NMR) In nuclear magnetic resonance spectroscopy and magnetic resonance imaging (MRI) the term relaxation describes several processes by which nuclear magnetization prepared in a non-equilibrium state return to the equilibrium distribution. In other words, relaxation describes how fast spins "forget" the direction in which they are oriented, processes by which nuclear magnetization returns to the equilibrium distribution
- Dielectric relaxation Dielectric relaxation is the momentary delay in the dielectric constant of a material. This is usually caused by the delay in molecular polarization with respect to a changing electric field in a dielectric medium (e.g. inside capacitors or between two large conducting surfaces). Dielectric relaxation in changing electric fields could be, the delay in the dielectric constant of a material
- Structural relaxation, responsible for the glass transition
- In mathematics:
- Relaxation technique (mathematics), a technique for transforming hard constraints into easier ones
- Relaxation method, for numerically solving elliptic partial differential equations
- In computer science:
- Relaxation, the act of substituting alternative program code during linking In computer science, a linker or link editor is a program that takes one or more objects generated by a compiler and combines them into a single executable program
In Physiology Physiology is the science of the functioning of living systems. It is a subcategory of biology. In physiology, the scientific method is applied to determine how organisms, organ systems, organs, cells and biomolecules carry out the chemical or physical function that they have in a living system. The word physiology is from Ancient Greek: φύσις, Hypnotism Hypnosis is a mental state or imaginative role-enactment (non-state theory) usually induced by a procedure known as a hypnotic induction, which is commonly composed of a long series of preliminary instructions and suggestions. Hypnotic suggestions may be delivered by a hypnotist in the presence of the subject, or may be self-administered (", Meditation Meditation is a holistic discipline during which time the practitioner trains his or her mind in order to realize some benefit, Recreation Recreation is any activity performed during one's leisure or free time. Recreational activities are often done for amusement, enjoyment or pleasure and are considered to be fun. Almost any activity can be considered recreational when engaged in during one's free time:
- Relaxation technique A relaxation technique is any method, process, procedure, or activity that helps a person to relax; to attain a state of increased calmness; or otherwise reduce levels of anxiety, stress or anger. Relaxation techniques are often employed as one element of a wider stress management program and can decrease muscle tension, lower the blood pressure, an activity that helps a person to relax
- Relaxed in Flow (psychology), a state of arousal, flow, over-learned self-control and relaxation
- Relaxation (psychology), the emotional state of low tension
