Parasympathetic nervous systemThe parasympathetic nervous system (PSNS) is one of the three divisions of the autonomic nervous system, the others being the sympathetic nervous system and the enteric nervous system. The enteric nervous system is sometimes considered part of the autonomic nervous system, and sometimes considered an independent system. The autonomic nervous system is responsible for regulating the body's unconscious actions.
MeditationMeditation is a practice in which an individual uses a technique – such as mindfulness, or focusing the mind on a particular object, thought, or activity – to train attention and awareness, and achieve a mentally clear and emotionally calm and stable state. Meditation is practiced in numerous religious traditions. The earliest records of meditation (dhyana) are found in the Upanishads, and meditation plays a salient role in the contemplative repertoire of Hinduism, Jainism and Buddhism.
Autonomic nervous systemThe autonomic nervous system (ANS), formerly referred to as the vegetative nervous system, is a division of the nervous system that supplies internal organs, smooth muscle and glands. The autonomic nervous system is a control system that acts largely unconsciously and regulates bodily functions, such as the heart rate, its force of contraction, digestion, respiratory rate, pupillary response, urination, and sexual arousal. This system is the primary mechanism in control of the fight-or-flight response.
Peripheral nervous systemThe peripheral nervous system (PNS) is one of two components that make up the nervous system of bilateral animals, with the other part being the central nervous system (CNS). The PNS consists of nerves and ganglia, which lie outside the brain and the spinal cord. The main function of the PNS is to connect the CNS to the limbs and organs, essentially serving as a relay between the brain and spinal cord and the rest of the body. Unlike the CNS, the PNS is not protected by the vertebral column and skull, or by the blood–brain barrier, which leaves it exposed to toxins.
Sympathetic nervous systemThe sympathetic nervous system (SNS) is one of the three divisions of the autonomic nervous system, the others being the parasympathetic nervous system and the enteric nervous system. The enteric nervous system is sometimes considered part of the autonomic nervous system, and sometimes considered an independent system. The autonomic nervous system functions to regulate the body's unconscious actions. The sympathetic nervous system's primary process is to stimulate the body's fight or flight response.
Buddhist meditationBuddhist meditation is the practice of meditation in Buddhism. The closest words for meditation in the classical languages of Buddhism are bhāvanā ("mental development") and jhāna/dhyāna (mental training resulting in a calm and luminous mind). Buddhists pursue meditation as part of the path toward liberation from defilements (kleshas) and clinging and craving (upādāna), also called awakening, which results in the attainment of Nirvana, and includes a variety of meditation techniques, most notably anapanasati (mindfulness of breathing).
Enteric nervous systemThe enteric nervous system (ENS) or intrinsic nervous system is one of the main divisions of the autonomic nervous system (ANS) and consists of a mesh-like system of neurons that governs the function of the gastrointestinal tract. It is capable of acting independently of the sympathetic and parasympathetic nervous systems, although it may be influenced by them. The ENS is nicknamed the "second brain". It is derived from neural crest cells.
Effects of meditationThe psychological and physiological effects of meditation have been studied. In recent years, studies of meditation have increasingly involved the use of modern instruments, such as fMRI and EEG, which are able to observe brain physiology and neural activity in living subjects, either during the act of meditation itself or before and after meditation. Correlations can thus be established between meditative practices and brain structure or function.
Christian meditationChristian meditation is a form of prayer in which a structured attempt is made to become aware of and reflect upon the revelations of God. The word meditation comes from the Latin word meditārī, which has a range of meanings including to reflect on, to study, and to practice. Christian meditation is the process of deliberately focusing on specific thoughts (such as a Bible passage) and reflecting on their meaning in the context of the love of God. Christian meditation aims to heighten the personal relationship based on the love of God that marks Christian communion.
Transcendental MeditationTranscendental Meditation (TM) is a form of silent mantra meditation developed by Maharishi Mahesh Yogi. The TM technique involves the use of a silently-used sound called mantra, and is practiced for 15–20 minutes twice per day. It is taught by certified teachers through a standard course of instruction, which costs a fee that varies by country. According to the Transcendental Meditation movement, it is a non-religious method that promotes relaxed awareness, stress relief, self-development, and higher states of consciousness.
Taoist meditationTaoist meditation (ˈdaʊɪst, ˈtaʊ-), also spelled Daoist (ˈdaʊ-), refers to the traditional meditative practices associated with the Chinese philosophy and religion of Taoism, including concentration, mindfulness, contemplation, and visualization. The earliest Chinese references to meditation date from the Warring States period (475–221 BCE). Traditional Chinese medicine and Chinese martial arts have adapted certain Daoist meditative techniques.
Jain meditationJain meditation (dhyāna) has been the central practice of spirituality in Jainism along with the Three Jewels. Jainism holds that emancipation can only be achieved through meditation or Shukla Dhyana. According to Sagarmal Jain, it aims to reach and remain in a state of "pure-self awareness or knowership." Meditation is also seen as realizing the self, taking the soul to complete freedom, beyond any craving, aversion and/or attachment. The practitioner strives to be just a knower-seer (Gyata-Drashta).
SportSport pertains to any form of physical activity or game, often competitive and organized, that aims to use, maintain, or improve physical ability and skills while providing enjoyment to participants and, in some cases, entertainment to spectators. Sports can, through casual or organized participation, improve participants' physical health. Hundreds of sports exist, from those between single contestants, through to those with hundreds of simultaneous participants, either in teams or competing as individuals.
Sports journalismSports journalism is a form of writing that reports on matters pertaining to sporting topics and competitions. Sports journalism started in the early 1800s when it was targeted to the social elite and transitioned into an integral part of the news business with newspapers having dedicated sports sections. The increased popularity of sports amongst the middle and lower class led to the more coverage of sports content in publications. The appetite for sports resulted in sports-only media such as Sports Illustrated and ESPN.
DysautonomiaDysautonomia or autonomic dysfunction is a condition in which the autonomic nervous system (ANS) does not work properly. This may affect the functioning of the heart, bladder, intestines, sweat glands, pupils, and blood vessels. Dysautonomia has many causes, not all of which may be classified as neuropathic. A number of conditions can feature dysautonomia, such as Parkinson's disease, multiple system atrophy, dementia with Lewy bodies, Ehlers-Danlos syndromes, autoimmune autonomic ganglionopathy and autonomic neuropathy, HIV/AIDS, autonomic failure, and postural orthostatic tachycardia syndrome.
HobbyA hobby is considered to be a regular activity that is done for enjoyment, typically during one's leisure time. Hobbies include collecting themed items and objects, engaging in creative and artistic pursuits, playing sports, or pursuing other amusements. Participation in hobbies encourages acquiring substantial skills and knowledge in that area. A list of hobbies changes with renewed interests and developing fashions, making it diverse and lengthy.
Stress managementStress management consists of a wide spectrum of techniques and psychotherapies aimed at controlling a person's level of stress, especially chronic stress, usually for the purpose of improving everyday functioning. Stress produces numerous physical and mental symptoms which vary according to each individual's situational factors. These can include a decline in physical health, such as headaches, chest pain, fatigue, and sleep problems, as well as depression.
Sports medicineSports medicine is a branch of medicine that deals with physical fitness and the treatment and prevention of injuries related to sports and exercise. Although most sports teams have employed team physicians for many years, it is only since the late 20th century that sports medicine emerged as a distinct field of health care. In some countries, sports medicine (or sport and exercise medicine) is a recognized medical specialty (with similar training and standards to other medical specialties).
BreathingBreathing (or ventilation) is the process of moving air into and from the lungs to facilitate gas exchange with the internal environment, mostly to flush out carbon dioxide and bring in oxygen. All aerobic creatures need oxygen for cellular respiration, which extracts energy from the reaction of oxygen with molecules derived from food and produces carbon dioxide as a waste product. Breathing, or "external respiration", brings air into the lungs where gas exchange takes place in the alveoli through diffusion.
Stress (biology)Stress, either physiological, biological or psychological, is an organism's response to a stressor such as an environmental condition. Stress is the body's method of reacting to a condition such as a threat, challenge or physical and psychological barrier. There are two hormones that an individual produces during a stressful situation, well known as adrenaline and cortisol. There are two kinds of stress hormone levels. Resting (basal) cortisol levels are normal everyday quantities that are essential for standard functioning.
