Springtime Lethargy
Springtime lethargy is the state of fatigue, lowered energy, or depression associated with the onset of spring. Such a state may be caused by a normal reaction to warmer temperatures, or it may have a medical basis, such as allergies or reverse seasonal affective disorder. In many regions, there is a springtime peak in suicide rates. Psychological and socio-cultural factors also play a role. The opening lines of Eliot's classic poem express some of the complex emotional associations that may be familiar to those who experience dark moods in the spring: Occasionally, such lethargy or depression may be described as "spring fever", though this term also relates to an ''increase'' in energy and restlessness or to romantic and sexual feelings in the spring. The German term '' Frühjahrsmüdigkeit'' (lit. "Spring fatigue") is the name for a temporary mood or physical condition, typically characterized by a state of low energy and weariness, experienced by many people in springtime. It ...

Seasonal Affective Disorder
Seasonal affective disorder (SAD) is a mood disorder subset, in which people who have normal mental health throughout most of the year exhibit depressive symptoms at the same time each year. Common symptoms include sleeping too much, having little to no energy, and overeating. The condition in the summer can include heightened anxiety.Seasonal affective disorder (SAD): Symptoms MayoClinic.com (September 22, 2011). Retrieved on March 24, 2013.

Seasonal Effects On Suicide Rates
Research on seasonal effects on suicide rates suggests that the prevalence of suicide is greatest during the late spring and early summer months, despite the common belief that suicide rates peak during the cold and dark months of the winter season. General effects The Center for Disease Control and Prevention and the National Center for Health Statistics report that suicide rates in the United States are lowest during the winter months and highest in the spring and summer. Stephen Bridges asserts that there is "a high incidence in early spring (April and May) and also a low incidence in winter" of suicide rates. Bridges's study focused on seasonal effects on suicide risk by examining the monthly distribution of suicides in the 1970s, 1980s, and 1990s via a "harmonic time series model" with six observable harmonic cycles within each consecutive year. The results show a consistent pattern of suicide risk with most suicides occurring in the spring/summer and the fewest during the ...

The Waste Land
''The Waste Land'' is a poem by T. S. Eliot, widely regarded as one of the most important poems of the 20th century and a central work of Modernist poetry in English, modernist poetry. Published in 1922, the 434-line poem first appeared in the United Kingdom in the October issue of Eliot's ''The Criterion'' and in the United States in the November issue of ''The Dial''. It was published in book form in December 1922. Among its famous phrases are "April is the cruellest month", "I will show you fear in a handful of dust", and the Sanskrit mantra "Shanti Mantras, Shantih shantih shantih". Eliot's poem combines the legend of the Holy Grail and the Fisher King with vignettes of contemporary British society. Eliot employs many literary and cultural allusions from the Western canon such as Ovid's Metamorphoses and Dante Alighieri, Dante's ''Divine Comedy'', as well as Shakespeare, Buddhism, and the Hinduism, Hindu Upanishads.

Spring Fever
Spring fever is any of a number of mood, physical, or behavioral changes which may be experienced coinciding with the onset of spring, particularly restlessness, laziness, and amorousness. Overview The term ''spring fever'' may refer to an increase in energy, vitality, and sexual appetite, as well as a feeling of restlessness, associated with the end of winter. This concept may have a biological basis. A lift in mood with the arrival of spring, and longer periods of daylight, is often particularly strong in those suffering from seasonal affective disorder (SAD), who experience lows or depression during the winter months. Symptoms of bipolar disorder are also more likely in spring. In the 17th and 18th centuries in Australia, Spring fever or Spring disease described an often fatal condition associated with skin lesions, bleeding gums and lethargy. The disease was later identified as scurvy Scurvy is a disease resulting from a lack of vitamin C (ascorbic acid). Early symptoms o ...

Serotonin
Serotonin () or 5-hydroxytryptamine (5-HT) is a monoamine neurotransmitter. Its biological function is complex and multifaceted, modulating mood, cognition, reward, learning, memory, and numerous physiological processes such as vomiting and vasoconstriction. Approximately 90% of the serotonin that the body produces is in the intestinal tract. Biochemically, the indoleamine molecule derives from the amino acid tryptophan, via the (rate-limiting) Tryptophan hydroxylase, hydroxylation of the 5 position on the ring (forming the intermediate 5-Hydroxytryptophan, 5-hydroxytryptophan), and then Aromatic L-amino acid decarboxylase, decarboxylation to produce serotonin. Serotonin is primarily found in the enteric nervous system located in the human gastrointestinal tract, gastrointestinal tract (GI tract). However, it is also produced in the central nervous system (CNS), specifically in the raphe nuclei located in the brainstem, Merkel cells located in the skin, Neuroendocrine cell#Pulmo ...

Melatonin
Melatonin is a natural product found in plants and animals. It is primarily known in animals as a hormone released by the pineal gland in the brain at night, and has long been associated with control of the sleep–wake cycle. In vertebrates, melatonin is involved in synchronizing circadian rhythms, including sleep–wake timing and blood pressure regulation, and in control of seasonal rhythmicity including reproduction, fattening, moulting and hibernation. Many of its effects are through activation of the melatonin receptors, while others are due to its role as an antioxidant. In plants, it functions to defend against oxidative stress. It is also present in various foods. Melatonin was discovered in 1958. In addition to its role as a natural hormone, melatonin is used as a dietary supplement and medication in the treatment of sleep disorders such as insomnia and circadian rhythm sleep disorders; for information on melatonin as a supplement and medication, see the mel ...

Endorphin
Endorphins (contracted from endogenous morphine) are chemical signals in the brain that block the perception of pain and increase feelings of wellbeing. They are produced and stored in an area of the brain known as the pituitary gland. History Opioid peptides in the brain were first discovered in 1973 by investigators at the University of Aberdeen, John Hughes (neuroscientist), John Hughes and Hans Kosterlitz. They isolated "enkephalins" (from the Greek language, Greek , ') from pig brain, identified as Met-enkephalin and Leu-enkephalin. This came after the discovery of a receptor that was proposed to produce the pain-relieving analgesic effects of morphine and other opioids, which led Kosterlitz and Hughes to their discovery of the endogenous opioid ligands. Research during this time was focused on the search for a painkiller that did not have the addictive character or overdose risk of morphine. Rabi Simantov and Solomon H. Snyder isolated morphine-like peptides from cal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Testosterone
Testosterone is the primary sex hormone and anabolic steroid in males. In humans, testosterone plays a key role in the development of male reproductive tissues such as testes and prostate, as well as promoting secondary sexual characteristics such as increased muscle and bone mass, and the growth of body hair. In addition, testosterone in both sexes is involved in health and well-being, including moods, behaviour, and in the prevention of osteoporosis. Insufficient levels of testosterone in men may lead to abnormalities including frailty and bone loss. Testosterone is a steroid from the androstane class containing a ketone and a hydroxyl group at positions three and seventeen respectively. It is biosynthesized in several steps from cholesterol and is converted in the liver to inactive metabolites. It exerts its action through binding to and activation of the androgen receptor. In humans and most other vertebrates, testosterone is secreted primarily by the testicles o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Estrogen
Estrogen or oestrogen is a category of sex hormone responsible for the development and regulation of the female reproductive system and secondary sex characteristics. There are three major endogenous estrogens that have estrogenic hormonal activity: estrone (E1), estradiol (E2), and estriol (E3). Estradiol, an estrane, is the most potent and prevalent. Another estrogen called estetrol (E4) is produced only during pregnancy. Estrogens are synthesized in all vertebrates and some insects. Their presence in both vertebrates and insects suggests that estrogenic sex hormones have an ancient evolutionary history. Quantitatively, estrogens circulate at lower levels than androgens in both men and women. While estrogen levels are significantly lower in males than in females, estrogens nevertheless have important physiological roles in males. Like all steroid hormones, estrogens readily diffuse across the cell membrane. Once inside the cell, they bind to and activate estrogen ...
