Simple steps to prevent back pain

Back pain is a common problem these days. Back pain is very hard to tolerate as you cannot take medicines and also you cannot exercise freely. Here are some good practices you should follow to prevent & cure back pain.

1. Improve your sitting posture

Wrong sitting posture is the main cause of back pain. Most of the seat backs are un-ergonomic which force an individual to sit in a wrong posture. Either use an ergonomic chair or, if you are using an ordinary chair, use an ergonomic backrest.. Amron backrest are specially designed to provide correct posture and maintain comfort which sitting on sofa & chair

2. Support Your Arms While Sitting In A Chair

Many aches and pains in the upper back may result from the muscles of the upper back growing tired of supporting the weight of the arms. If possible use a chair with arms.

3. Set Up Your Workstation Correctly

Organize your computer, telephone & other office equipment close in your field of vision & reach. Incorrect placement of your computer can cause neck, shoulder, and back pain and even headaches.

4. Stay Active & Change Positions

Without movement, even the best chair cannot keep your back happy; your back hates to sit & not move. If you must stay seated, change positions as frequently as possible.

5. Try heat, cold or massage

Use a heating pad or Hot Water Bottle bottle to apply heat to your back, or alternate Ice Packs or Cool Packs with heat. Rubbing your back also might help.

6. Put Your Foot Up

Prolonged standing causes backache. The best thing to do is alternate sitting & standing if you can, but if you can't, the next best choice is resting your foot on a prop. Try placing one foot at a time up on a footstool or any four- to six-inch block or box. When your foot is elevated, the muscles of the front of your thigh and pelvis relax. Because these muscles affect the bones and disks of your low back.

How to relieve Back Pain during pregnancy?

Some simple steps to Reduce Back Pain during Pregnancy

Back pain is a common problem these days. Back pain during pregnancy is very hard to tolerate as you can not take medicines and also you can not exercise freely. Here are some good practices you should follow to prevent & cure back pain during pregnancy.

1. Practice Good Posture

Good posture is all about the position of sitting on chair, sofa or bed. It also means sitting with care. Always choose a backrest that support your lower back while sitting on sofa, bed & chair. Keep your upper back and neck comfortably straight. Consider propping your feet on a low stool. Amron backrest are specially designed to provide correct posture and maintain comfort which sitting on sofa & chair

2. Wear low-heeled shoes with good arch support

Always prefer wearing maternity pants with low and supportive waistband. Also, consider wearing a maternity support belt.

3. Do not lift heavy object

Do not lift any heavy items during pregnancy. and also when lifting any small object, squat down and lift with your legs. Don not bend at the waist or lift with your back. Ask for help whenever required.

4. Sleep on your sides

Prefer sleeping on your sides, not on the back. Keep one or both knees bent. It might also help to place one pillow between your knees and another under your abdomen.

5. Try heat, cold or massage

Use a heating pad or Hot Water Bottle bottle to apply heat to your back, or alternate Ice Packs or Cool Packs with heat. Rubbing your back also might help.

6. Exercise Daily or do some physical activity in your daily routine

Do some restricted exercises after consulting to your doctor. Regular physical activities can keep your back strong and may actually relieve back pain during pregnancy. After consultation from Doctor, try gentle activities such as walking.

Blood Pressure - common problem now a days?

What is Blood Pressure? How to measure blood pressure? What are the best blood pressure equipment in India?

Blood Pressure has become a major problem in today's life style. Regular check up and monitoring of BP is the simplest way to control it over the period of time.
Blood pressure is that pressure which is exerted by circulating blood upon walls of blood vessels. Blood Pressure usually refers to the arterial pressure of the systemic circulation. During each heartbeat, blood pressure varies between a maximum (systolic) and a minimum (diastolic) pressure. The blood pressure in the circulation is principally due to the pumping action of the heart. Differences in mean blood pressure are responsible for blood flow from one location to another in the circulation. The rate of mean blood flow depends on the resistance to flow presented by the blood vessels. Mean blood pressure decreases as the circulating blood moves away from the heart through arteries, capillaries and veins due to viscous losses of energy. Mean blood pressure drops over the whole circulation, although most of the fall occurs along the small arteries and arterioles. Gravity affects blood pressure via hydro-static forces (e.g. while person stands) and valves in veins, breathing, and pumping from contraction of skeletal muscles also influence blood pressure in veins. The blood pressure of a person is usually expressed in terms of the systolic pressure over diastolic pressure and is measured in millimeters of mercury (mmHg), for example 120/80.
What is the Normal Blood Pressure? What are the different types of blood pressures? Normal blood pressure values fluctuate through the 24-hour cycle, with highest readings in the afternoons and lowest readings at night. It also varies person to person, depending on their diet, routine, life style. However, in a study of 100 human subjects with no known history of any problem, an average blood pressure is found to be 112/64 mmHg. Various factors control blood pressure, such as age and gender influence average values; influence a person's average blood pressure and variations. In children, the normal ranges are lower than for adults and depend on height. In adults, systolic pressure tends to rise and diastolic tends to fall. In old people, blood pressure tends to be above the normal adult range, largely because of reduced flexibility of the arteries. Differences between left and right arm blood pressure measurements tend to be random and average to nearly zero if enough measurements are taken. However, in a small percentage of cases there is a consistent difference greater than 10 mmHg which may need further investigation. The risk of cardiovascular disease increases progressively above 115/75 mmHg. In the past, hypertension was only diagnosed if secondary signs of high arterial pressure were present, along with a prolonged high systolic pressure reading over several visits. Regarding hypo-tension, in practice blood pressure is considered too low only if noticeable symptoms are present. Clinical trials demonstrate that people who maintain arterial pressures at the low end of these pressure ranges have much better long term cardiovascular health.
Hypertension refers to arterial pressure being abnormally high, as opposed to hypo-tension, when it is abnormally low. Along with body temperature, respiratory rate, and pulse rate, blood pressure is one of the four main vital signs routinely monitored by medical professionals and healthcare providers.
Some physical factors are:
  • Heart Rate, the rate at which blood (the fluid) is pumped by the heart. The volume of blood flow from the heart is called the cardiac output which is the heart rate (the rate of contraction) multiplied by the stroke volume (the amount of blood pumped out from the heart with each contraction).
  • Volume of blood, the amount of blood that is present in the body. The more blood present in the body, the higher the rate of blood returns to the heart and the resulting cardiac output. There is some relationship between dietary salt intake and increased blood volume, potentially resulting in higher arterial pressure.
  • Resistance, this is the resistance of the blood vessels. The higher the resistance, the higher the arterial pressure upstream from the resistance to blood flow. Resistance is related to vessel radius (the larger the radius, the lower the resistance), vessel length (the longer the vessel, the higher the resistance), blood viscosity, as well as the smoothness of the blood vessel walls. Smoothness is reduced by the build up of fatty deposits on the arterial walls. Substances called vasoconstrictors can reduce the size of blood vessels, thereby increasing blood pressure. Vasodilators (such as nitro-glycerin) increase the size of blood vessels, thereby decreasing arterial pressure.
  • Viscosity, or thickness of the fluid. If the blood gets thicker, the result is an increase in arterial pressure. Certain medical conditions can change the viscosity of the blood. For instance, anemia (low red blood cell concentration), reduces viscosity, whereas increased red blood cell concentration increases viscosity. It had been thought that aspirin and related "blood thinner" drugs decreased the viscosity of blood, but instead studies found that they act by reducing the tendency of the blood to clot.

Measurement - How to measure blood pressure? What are the equipment to calculate blood pressure?
Arterial pressure is most commonly measured via a sphygmomanometer, which historically used the height of a column of mercury to reflect the circulating pressure. Blood pressure values are generally reported in millimeters of mercury (mmHg), though aneroid and electronic devices do not use mercury. For each heartbeat, blood pressure varies between systolic and diastolic pressures. Systolic pressure is peak pressure in the arteries, which occurs near the end of the cardiac cycle when the ventricles are contracting. Diastolic pressure is minimum pressure in the arteries, which occurs near the beginning of the cardiac cycle when the ventricles are filled with blood. An example of normal measured values for a resting, healthy adult human is 120 mmHg systolic and 80 mmHg diastolic (120/80 mmHg, "one-twenty over eighty").
Here are the simple steps to measure Blood Pressure at home. Place the cuff around the upper arm. Note-Patient should be seated with some support to the arm. Inflate the cuff and place stethoscope at the elbow. It is essential that the cuff size is correct: undersized cuffs may yield too high a pressure; over sized cuffs yield too low a pressure. Now release the pressure of cuff and listen carefully for a pounding sound. Note the pressure where this sound starts, this would be the systolic blood pressure. Further release the pressure until this sound stops; this would be the diastolic blood pressure.

High Blood Pressure Hypertension - Overview of main complications of persistent high blood pressure. Arterial hypertension can be an indicator of other problems and may have long-term adverse effects. Sometimes it can be an acute problem, for example hypertensive emergency. All levels of arterial pressure put mechanical stress on the arterial walls. Higher pressures increase heart workload and progression of unhealthy tissue growth (Atheroma) that develops within the walls of arteries. The higher the pressure, the more stress that is present and the more atheroma tend to progress and the heart muscle tends to thicken, enlarge and become weaker over time. Persistent hypertension is one of the risk factors for strokes, heart attacks, heart failure and arterial aneurysms, and is the leading cause of chronic renal failure. Even moderate elevation of arterial pressure leads to shortened life expectancy. At severely high pressures, mean arterial pressures 50% or more above average, a person can expect to live no more than a few years unless appropriately treated. In the past, most attention was paid to diastolic pressure; but nowadays it is recognized that both high systolic pressure and high pulse pressure (numerical difference between systolic and diastolic pressures) are also risk factors. In some cases, it appears that a decrease in excessive diastolic pressure can actually increase risk, due probably to the increased difference between systolic and diastolic pressures (see the article on pulse pressure). If systolic blood pressure is elevated (>140) with a normal diastolic blood pressure (<90), it is called "isolated systolic hypertension" and may present a health concern. For those with heart valve regurgitation, a change in its severity may be associated with a change in diastolic pressure. In a study of people with heart valve regurgitation that compared measurements 2 weeks apart for each person, there was an increased severity of aortic and mitral regurgitation when diastolic blood pressure increased, whereas when diastolic blood pressure decreased, there was a decreased severity.

Low Blood Pressure Hypo tension - Blood pressure that is too low is known as hypotension. The similarity in pronunciation with hypertension can cause confusion. Hypotension is a medical concern only if it causes signs or symptoms, such as dizziness, fainting, or in extreme cases, shock. When arterial pressure and blood flow decrease beyond a certain point, the perfusion of the brain becomes critically decreased (i.e., the blood supply is not sufficient), causing light-headedness, dizziness, weakness or fainting. Sometimes the arterial pressure drops significantly when a patient stands up from sitting. This is known as orthostatic hypotension (postural hypotension); gravity reduces the rate of blood return from the body veins below the heart back to the heart, thus reducing stroke volume and cardiac output. When people are healthy, the veins below their heart quickly constrict and the heart rate increases to minimize and compensate for the gravity effect. This is carried out involuntarily by the autonomic nervous system. The system usually requires a few seconds to fully adjust and if the compensations are too slow or inadequate, the individual will suffer reduced blood flow to the brain, dizziness and potential blackout. Increases in G-loading, such as routinely experienced by aerobatic or combat pilots 'pulling Gs', greatly increases this effect. Repositioning the body perpendicular to gravity largely eliminates the problem.

Fluctuating blood pressure Normal fluctuation in blood pressure is adaptive and necessary. Fluctuations in pressure that are significantly greater than the norm are associated with greater white matter hyperintensity, a finding consistent with reduced local cerebral blood flow and a heightened risk of cerebrovascular disease. Within both high- and low-blood pressure groups, a greater degree of fluctuation was found to correlate with an increase in cerebrovascular disease compared to those with less variability, suggesting the consideration of the clinical management of blood pressure fluctuations, even among normotensive older adults. Older individuals and those who had received blood pressure medications were more likely to exhibit larger fluctuations in pressure.

White-coat hypertension - For some patients, blood pressure measurements taken in a doctor's office, clinic or hospitals may not correctly characterize their typical blood pressure. In up to 25% of patients, the measurement at clinic is higher than their typical blood pressure. This type of error is called white-coat hypertension (WCH) and can result from anxiety related to an examination by a health care professional. The misdiagnosis of hypertension for these patients can result in needless and possibly harmful medication. WCH can be reduced with automated blood pressure measurements over 15 to 20 minutes at home.

Home monitoring of Blood Pressure - Ambulatory blood pressure devices that take readings every half hour throughout the day and night have been used for identifying and mitigating measurement problems like white-coat hypertension. Except for sleep, home monitoring could be used for these purposes instead of ambulatory blood pressure monitoring. Home monitoring may be used to improve hypertension management and to monitor the effects of lifestyle changes and medication related to blood pressure. Compared to ambulatory blood pressure measurements, home monitoring has been found to be an effective and lower cost alternative, but ambulatory monitoring is more accurate than both clinic and home monitoring in diagnosing hypertension. Ambulatory monitoring is recommended for most patients before the start of anti-hypertensive drugs. Aside from the white-coat effect, blood pressure readings outside of a clinical setting are usually slightly lower in the majority of people. The studies that looked into the risks from hypertension and the benefits of lowering blood pressure in affected patients were based on readings in a clinical environment. When measuring blood pressure, an accurate reading requires that one not drink coffee, smoke cigarettes, or engage in strenuous exercise for 30 minutes before taking the reading. A full bladder may have a small effect on blood pressure readings; if the urge to urinate exists, one should do so before the reading. For 5 minutes before the reading, one should sit upright in a chair with one's feet flat on the floor and with limbs uncrossed. The blood pressure cuff should always be against bare skin, as readings taken over a shirt sleeve are less accurate. During the reading, the arm that is used should be relaxed and kept at heart level, for example by resting it on a table. Since blood pressure varies throughout the day, measurements intended to monitor changes over longer time frames should be taken at the same time of day to ensure that the readings are comparable. Suitable times are: immediately after awakening (before washing/dressing and taking breakfast/drink), while the body is still resting, immediately after finishing work. It is always good to be proactive rather that reactive. Blood Pressure monitor is an asset to have in your house. You can keep a track of your health and caught any BP diseases in early stages.
