what is orthostatic stress?

Orthostasis = standing upright. Orthostatic intolerance can then be defined as "the development of symptoms during upright standing relieved by recumbency". Often, illnesses producing orthostatic intolerance include disorders of blood flow, heart rate and blood pressure regulation that, while most easily demonstrable during orthostatic stress, are present in all positions. The term "dysautonomia", signifying autonomic dysfunction, has been frequently applied to this list of disorders, but recent data suggest that autonomic function may be normal in many variants of these conditions but have to cope with unusual circulatory demands. A simple and common example of this is the finding of postural hypotension and postural tachycardia when dehydrated. Therefore it is probably best to denote the type of symptomatic illness by the more vague term "orthostatic intolerance" rather than the more specific term"dysautonomia" which may not be correct.  Acute orthostatic intolerance usually manifests as syncope (fainting). Many syncopal patients have no intercurrent illness; between faints they are well.  \nSymptoms of Orthostatic Intolerance\n\nLightheadeness\n\nHeadache              \nFatigue   \nNeurocognitive/Sleep Disorders\nVisual Disturbances (black/white/spots) \nExercise intolerance   \nWeakness   \nHyperpnea/Dyspnea \nTremulousness   \nSweating \nAnxiety/Palpitations   \n \n\nChronic orthostatic intolerance implies day-to-day symptoms including dizziness in all patients, and often altered vision (blurred, �white outs�, �black-outs�), fatigue, nausea, neurocognitive deficits, disordered thermoregulation, palpitations, headache, tremulousness, hyperpnea, difficulty breathing, sweating, and pallor. These produce day-to-day disability; estimates suggest that over a million Americans are affected, mostly young women, who may be prevented from gainful employ or school attendance. Chronic orthostatic intolerance is associated with postural tachycardia syndrome (POTS). When symptoms of chronic orthostatic intolerance are present, signs of POTS are almost always found. Most forms of orthostatic intolerance are not typically life threatening although circumstances can conspire to create considerable risk.  \n\nEvidence suggests that the changes in heart rate, blood pressure, and cerebral blood flow that produce orthostatic intolerance may be related to abnormalities in the interplay between blood volume control, the cardiovascular system, the autonomic nervous system and local circulatory mechanisms that regulate these basic physiological functions. Therefore, the control of the circulatory system should be considered neurovascular, resulting from the interactions between neurological and cardiovascular systems. These interactions, may alter blood flow through direct effects on blood pressure, by redistribution of blood flow resulting in altered blood return  to the heart and drastic reductions in the amount of blood that the heart can pump (cardiac output), and by local flow regulatory mechanisms that impair cerebral blood flow . This results in decreases in blood flow to the skin and muscles producing pallor, and decreases in blood flow to the brain producing light-headedness or loss of consciousness although respiratory changes may produce hypocapnea and cerebral vasoconstriction that precedes changes in blood pressure. This rather striking hyperpnea and associated dyspnea may even be produced in healthy volunteer subjects and is often observed prior to overt circulatory failure in fainting and chronic orthostatic intolerance. Separate evidence also indicates the potential for abnormal central nervous system autoregulation which normally spares the brain from the consequences of low flow states. While there is often evidence for impaired neurovascular interactions while supine, orthostasis (standing up) profoundly stresses the control mechanisms. Thus symptoms of neurovascular regulatory fa

A positive tilt table test indicates (as you probably know) that your heart is beating inappropriately to maintain appropriate blood pressure.  Your blood pressure drops and you faint.  Normally your body would enlist a number of mechanisms to prevent fainting...the arteries should constrict, the heart should beat faster to compensate.  Something, however is going awry.  It might be that your heart is beating waaay too fast - hence POTS.  But that's far from a forgone conclusion.  And NMS is mostly a diagnosis of exclusion...if everything else checks out, then we are left with NMS.\n\nThe cardiologists role is to tease all of this out.  What is happening exactly with your heart when this phenomenon occurs?  They also will want to make sure the structures are working like they are supposed to...normal contractions, normal valvular function, etc.  They also can be helpful in monitoring your heart over a period of a couple days to determine if your heart goes too fast, too slow, or what.\n\nAs far as treatments are concerned, you first need a diagnosis in order to discuss treatment.  Try not to worry.  The plan is to get more information and get to the bottom of all of this.  Once there is more information then it will direct treatment.\n\nGood luck.

You can get a condition called suspension trauma which is caused by orthostatic intolerance where your body is required to stand in the same position for long periods. This condition affects soldiers on parade grounds and can cause death.\n\nSafety harnesses save many lives and injuries. However, continual vigilance is needed to train and supervise workers to ensure harnesses are used safely. All phases of fall protection need to be examined for each particular application. Workers and emergency response personnel must be trained to recognize the risks of suspension trauma.

Stress is the way our body and mind deals with a stimuli.  Increased levels of stress affect us by limiting the number of hours of sleep we get per night, mainly due to the fact that our mind isn't calm enough to sleep.\n\nIn the long run, stress can weaken the immune syste, can shorten  your life span, and can severly inhibit your ability to get a full REM sleep.\n\nThe best way to deal with this issue, is to simply find an outlet for your stress.  Once found, simply practicie letting go of the stress and sleeping in a dimly lit room, without any outside stimuli.

Stress is tension or pressures that are a natural part of living our lives.  Changes and events in our lives (getting married, illness, changing jobs) are a major source of stress.  Pressures and tension from both good and bad changes can trigger our Stress Alarm System making us feel that we want to either fight the stress or run away from it.  \n\nPreventing Stress:\nEating Right Helps:  Foods high in preotein, Vitamin C, B vitamins and Vitamin A protect us from the effects of stress.  These are found in whole grain products, fruits and veggies, expecially citrus fruits, dark green veggies, meat and dairy products.  Caffeine, refined sugars, starches and junk food create false energy and stress the body even more.\nManage Time Better:  Take five minutes at the beginning of each day and make a "things to do" list.  Converty this list into a priority list of primary tasks, secondary tasks and miscellaneous tasks.  Do Primary tasks first and continue until the list is completed.  Don't over schedule - leave time for unexpected events.  Reward yourself for a job well done.\nExercise your tension away:  You feel healthier and less stressed when you develop an exercise plan that meets your life style, needs and ability.  Yoga and stretching exercises are good for developing flexibility and relaxation.  \nIn a nut shell:  everyone will get stressed.. but how to manage your stress and keep it from occuring as often just takes a few little changes throughout your day to make it much easier to get through the bad parts!

Two words.  LOT LIZARDS.  That should relieve some stress.  Or you could try those breathing exercises.  Take 3 deep breaths and hold for 3 seconds and keep doing it until you feel better.

Clean out a closet, wash the floor, take a walk for 30 minutes...burn off the stress with something physical.  It is a temporatary band aide only though.  Real stress needs to be dealth with or it will leave you with physiological problems somewhere in the body.  What goes on above the neck affects what goes on below the neck.

The reason for the fainting is called Vaso-vagal syncope.  In a nutshell what happens is that the brain sends a signal to the body that is out of proportion to the stimulus.  This signals, amongst others, is sent to the heart causing it to slowdown drastically (H.R. 40-50 bpm; Normal 60-100) and a drop in blood pressure.  This reduces the blood supply to the brain and by consequence results in fainting.  When this happens ppl usually feel it coming on and feel hot, clammy and dizzy.  The best way to avoid actually fainting is to lay down flat on the ground and raise the legs up (help blood return to the heart and allows it to be sent to the brain more easily).  This is by no means dangerous apart from the high risk of a fall injury.\n\nFor more information do a search on vasovagal syncope

Stress\nEveryday we are confronted with problems. When we are confronted with a problem we must determine the seriousness of the problem and determine whether or not we have the resources (e.g., emotional resources) necessary in order to cope with problem. If we believe that the problem is serious and we also believe that we do not have the resources necessary to cope with the problem, we will perceive ourselves as being under stress (Cohen et. al., 1995). Stress can be defined as a process in which environmental demands strain an organisms adaptive capacity, resulting in both psychological as well as biological changes that could place a person at risk for illness (Cohen et. al., 1995). Things that cause us stress are called stressors (Rubin, Paplau, & Salovey, 1993). Many events can be thought of as stressors. These include disasters, life crises, life changes, and daily hassles (Rubin, Paplau, & Salovey, 1993). Examples of stressors include: hurricanes, earthquakes, disease, divorce, unemployment, marriage, and traffic jams. Stressors are things that interfere with an important personal goal (Rubin, Paplau & Salovey, 1993). The more important the goal is, the more stress a person will feel when that goal is threatened (Rubin, Paplau & Salovey, 1993). So for example, if it's important to a person to get to class on time, the person will feel stress if he gets caught in traffic. The goal is to get to class on time and the stressor is the traffic jam. The more important it is for the person to be on time, the more stressful the traffic jam will be. So, a person is likely to feel more stress on the day when an exam is given and there is a traffic jam, than he will feel when no exam is given and there is a traffic jam. \nThree Theories of Stress. Stress affects everyone, young and old, rich and poor. Life is full of stress. There is work stress, school stress, financial stress, and emotional stress, to name a few. There are three theories or perspectives regarding stress. There is the environmental stress perspective, the psychological stress perspective, and the biological stress perspective. The environmental stress perspective emphasizes assessment of environmental situations or experiences that are objectively related to substantial adaptive demands (Cohen et. al., 1995). The psychological stress perspective emphasizes people's subjective evaluations of their ability to cope with the demands presented to them by certain situations and experiences (Cohen et. al., 1995). Finally, the biological stress perspective emphasizes the activation of certain physiological systems in the body that have been shown time and time again to be regulated by both psychologically and physically demanding conditions (Cohen et. al., 1995). \n\nStress and Biology. Stress is not necessarily a bad thing. A certain amount of stress is natural. None of us live stress free lives. However, while a certain amount of stress is normal, chronic negative stress may be harmful to our health. Thomas Holmes asserted that any and all change is stressful because it forces individuals to adapt to new, unfamiliar circumstances (Brehm & Kassin, 1993). Holmes acknowledged that some changes require more of an adjustment than other changes (Brehm & Kassin, 1993). Holmes believes that the change resulting from both positive (e.g., marriage, promotion, graduation) and negative (e.g., divorce, unemployment) life events are stressful and may possibly do harm to an individual's health (Brehm & Kassin, 1993). When an individual is faced with stress, his body mobilizes for action in what is called a fight or flight reaction (Rubin, Paplau, & Salovey, 1993). During a fight or flight reaction, the heart rate increases, breathing is accelerated, and the muscles tense up as if in preparation to throw something like a rock (fight) or to run away (flight) (Rubin, Paplau, & Salovey, 1993). For example, when approached by a thief, you can either fight him or you can try t

Odds are good you are under a lot of stress. Many people carry their tension in their upper shoulders and neck. I would suggest that you should see a chiropractor or massage therapist.
