A Wisdom Archive on Stress

Worry causes fear, anxiety, tension and stress. These emotions deplete energy and weaken the immune system. Worriers become sick and this is manifested in poor health, because of all the problems that are eating into their vitals.
 
And worry is certainly not the same as constructive thinking; if it were, we would have found solutions to most of our problems.

In solid mechanics, Young's modulus (also known as the modulus of elasticity or elastic modulus) is a measure of the stiffness of a given material. It is defined as the limit for small strains of the rate of change of stress with strain. This can be experimentally determined from the slope of a stress-strain curve created during tensile tests conducted on a sample of the material. Young's modulus is named after Thomas Young the English physicist, physician, and Egyptologist. Young's modulus - Units. Including:

Clinical Depression is state of sadness or melancholia that has advanced to the point of being disruptive to an individual's social functioning and/or activities of daily living (ADLs). The diagnosis may be applied when an individual meets a sufficient number of the symptomatic criteria for the Depression spectrum as suggested in the DSM-IV-TR or ICD-9/10. It is important to note that an individual may suffer from what is termed a "clinical depression" without fully meeting the criteria for a specific diagnosis on the Depression spect ... Including:

CSR is a fluid detachment of macula layers from their supporting tissue. This allows choroidal fluid to leak into the subretinal space. The buildup of fluid seems to occur because of small breaks in the retinal pigment epithelium. CSR is sometimes called idiopathic CSR which means that its cause is unknown. Nevertheless, stress appears to play an important role. Persons in stressful occupations, such as airplane pilots, have a higher incidence of CSR. The "type A ...

Psychologically, it is possible to become habituated to a degree of stimulation, and then find it uncomfortable to have significantly more or less. Thus one can become used to an intense life, or television, and suffer withdrawal when they are removed, from lack of stimulation, and it is possible to also be unhappy and stressed due to additional abnormal stimulation. It is hypothesized and commonly believed by some that psychological habituation to a high level of stimulation ("over-stimulation") can lead to psychological problems. Fo ...

The Young's modulus allows the behavior of a material under load to be calculated. For instance, it can be used to predict the amount a wire will extend under tension, or to predict the load at which a thin column will buckle under compression. Some calculations also require the use of other material properties, such as the shear modulus, density, or Poisson's ratio. Young's modulus - Linear vs non-linear. For many materials, Young's modulus is a constant over a range of strains. Such materials are called ...

Treatment of depression varies broadly, and is different for each individual. Various types and combinations of treatments may have to be tried. There are two primary modes of treatment, typically employed in conjunction with one another: medication and psychotherapy. A third treatment, electro-convulsive therapy (ECT) may be used where chemical treatment fails. Other alternative treatments used for depression include exercise and the use of v ...

Tinnitus is a phenomenon of the nervous system connected to the ear, characterised by perception of a ringing or beating sound (often perceived as sinusoidal) with no external source. This sound may be a quiet background noise, or loud enough to drown out all outside sounds. It is sometimes refered to as "the club disease" as many people get temporary tinnitus at loud clubs or concerts. Tinnitus can be objective (the sound, e.g., a bruit, can be perceived by a clinician) or subjective (perceived only by the patient). ... Including:

• Tinnitus - Treatment
• Tinnitus - Mechanisms of subjective tinnitus

Clinical depression - Anxiety. The different types of Depression and Anxiety are classified separately by the DSM-IV-TR, with the exception of hypomania, which is included under the Bipolar Disorder category. Despite the different categories, depression and anxiety can indeed be co-occurring (occurring together, independently, and without mood congruence), or co-morbid (occurring together, with overlapping symptoms, and with mood congruence). In an effort to bridge the gap between the DSM-IV-TR categories and wha ...
