In the sciences, the term is used in the following ways: Relaxation (physics), and more in particular: Relaxation (NMR), processes by which nuclear magnetization returns to the equilibrium distribution
Stress is the leading cause of mental and physical problems, [citation needed] therefore feeling relaxed is often beneficial for a person's health. When a person is highly stressed, the sympathetic nervous system is activated because one is in a fight-or-flight response mode; over time, this could have negative effects on a human body .
In condensed matter physics, relaxation is usually studied as a linear response to a small external perturbation. Since the underlying microscopic processes are active even in the absence of external perturbations, one can also study "relaxation in equilibrium" instead of the usual "relaxation into equilibrium" (see fluctuation-dissipation theorem).
Calmness is a quality that can be cultivated and increased with practice, [7] [better source needed] or developed through psychotherapy. [8] It usually requires training for one's mind to stay calm in the face of a great deal of different stimulation, and possible distractions, especially emotional ones.
A Lagrangian relaxation of a complicated problem in combinatorial optimization penalizes violations of some constraints, allowing an easier relaxed problem to be solved. Relaxation techniques complement or supplement branch and bound algorithms of combinatorial optimization; linear programming and Lagrangian relaxations are used to obtain ...
Relaxed stability designs are not limited to military jets. The McDonnell Douglas MD-11 has a neutral stability design which was implemented to save fuel. To ensure stability for safe flight, an LSAS (Longitudinal Stability Augmentation System ) was introduced to compensate for the MD-11's rather short horizontal stabilizer and ensure that the ...
Progressive muscle relaxation aims to reverse these body states back to more neutral, relaxed states. [6] The technique is a two-step process. [7] It involves learning to relieve the tension in specific muscle groups by first tensing and then relaxing each muscle group. [3]
Relaxed Muscle seemed to fade away after their album release in 2003. Pulp remained on a hiatus. However, Cocker and Buckle worked on the soundtrack for Harry Potter and the Goblet of Fire which was released in November 2005 and have since worked together on Cocker's solo album Jarvis (2006).
