In our family tradition, someone 's feelings and bodily functions are often blamed on weather. When my grandmother 's blood pressure begins to change, she will claim it is a result of shifting atmospheric conditions; when I feel down, she links it with my low blood pressure and consequently blames my feelings on weather as well. I 'm inclined to believe my mood isn 't linked with blood pressure or with what kinds of events are taking place in the sky, since I can feel low even when my blood pressure is relatively high and the weather is pleasant, but her assertions make me wonder if a correlation really does exist between these phenomena. I know that on rainy days I indeed feel sleepier and lethargic, behaviors that are hallmarks of lower blood pressures, but are my body 's homeostatic behaviors really this sensitive to the conditions around me?
Blood pressure is a descriptor of the force that blood exerts on the walls of arteries through which it travels, and this pressure varies with the rhythmic contractions of the separate parts of the heart. Systolic pressure occurs when the cardiac muscles on the atrial or ventricular portion of the heart tighten to either move blood from the atria to the ventricles or expel blood from the heart. The ventricular systole, which pushes blood out of the ventricles into the pulmonary artery and aorta, is the strongest and most noticeable of the two and results in the highest pressure change in arteries. A pause between the systolic contractions is called the diastole, when the heart is at rest and the atria are filling up with blood; no events take place to raise the blood pressure at this time. The blood pressure during the systolic and diastolic phases of the heart rhythm can be measured by a...

... possible that any discomfort induced by less sunlight, or the lifting of depression with the onset of warmer weather can have an effect on blood pressure. The amount of cloud cover is related to air pressure, since lower air pressures allow moisture to rise into the higher atmosphere and condense into clouds, and vice versa; this would vindicate my grandmother 's opinion that blood pressure and weather, including both atmospheric conditions and barometric pressure, are connected after all, albeit the relationship will prove to be an indirect one and through a different cause-and-effect system from her assertions. For this reason, this study will record both the blood pressure and mood of an individual in conjunction with weather conditions relating to temperature and barometric pressure for the purpose of elucidating if any relationships exist between these factors.

Common Reason For High Blood Pressure Essay

- High Blood Pressure High Blood Pressure is anything that alters in peripheral vascular resistance, heart rate, or stroke volume that affects systematic arterial blood pressure. Long term effect of high blood pressure are serious and can cause heart attacks, strokes, kidney failure, and retinal damage. Hypertension is another medical word that substitutes the meaning of high blood pressure. It is known as the “silent killer” because it does not create any symptoms. The most common reason for high blood pressure is arteriosclerosis....   [tags: Blood pressure, Blood, Hypertension, Artery]

Essay on The Effect Of Blood Pressure On The Blood Vessels

- Introduction Homeostasis involves the body’s ability to maintain a relatively constant and stable environment, which can be achieved through a series of negative feedback mechanisms. (Cannon, 1926) Blood Pressure is one of those feedback mechanisms and is the pressure that is exerted on the walls of arteries and blood vessels throughout your body driven by the pressure created by the pumping of your heart, usually within the systemic system. The flow is directly proportional to the pressure gradient and this is known as fluid flow....   [tags: Blood pressure, Artery, Heart, Pulse]

Meditation And Its Effect On Blood Pressure Essay

- Introduction Commonly, most people associate mediation with a super relaxed state, however meditation as a discipline requires great practice skill. This intensity could cause a physiological response opposite to what most expect from meditation (Lumma, Kok, Singer). However, some studies showed that meditation combined with breathing techniques, similar to those we used during our guided meditation, decreased the heart rate, systolic, and diastolic pressure of patients with hypertension (Angermann et al)....   [tags: Blood pressure, Hypertension, Blood, Artery]

Factors That Affect High Blood Pressure Essay

- There is about 90% of Americans in the United States that are unaware that they have high blood pressure (LeMone, Burke, & Bauldoff, 2011, p. 1017). “High blood pressure is one of the three main risk factors for heart disease with some being smoking and high cholesterol (Kennedy, 2011, p. 39).” “It is known that the higher the systolic and diastolic blood pressure, the more the patient will be at risk for coronary heart disease and stroke (Kennedy, 2011, p. 39).” Several factors are known to influence blood pressure such as lifestyle, diet, smoking, and taking regular physical activity....   [tags: Blood pressure, Hypertension, Artery]

- ... A meta-analysis of prospective cohort studies reveals that increased consumption of fruit and vegetables from less than three to more than five servings/day correlates with a 17% reduction in coronary heart disease risk (He, Nowson, Lucas, & MacGregor, 2007). The hypothesis that dietary fibres protect from ischemic heart disease was introduced in 1970s (Trowell, 1972). Since then, a diet rich in fibre has been linked to the CVD risk factors (e.g. obesity, high cholesterol and hypertension) (Van Horn et al., 2008; Truswell, 2002)....   [tags: systolic, diastolic blood pressure ]

High Blood Pressure Can Be Controlled Through Healthy Eating Essay

- As blood flows through the body, it exerts stress on blood vessel walls; creating an effect known as blood pressure. Blood pressure is measured by “the force in the arteries when the heart beats (systolic pressure) and when the heart is at rest (diastolic pressure)” (American Heart Association [AHA], 2008, para. 1). An average healthy adult’s blood pressure has a measurement of 120 over 80 or less (AHA, 2008, para. 3). “High blood pressure (also called hypertension) occurs when your blood moves through your arteries at a higher pressure than normal” (AHA, 2006, para....   [tags: Cholesterol Health Blood Pressure]

Blood Pressure and Heart Rate at Rest and During Exercise: What Are the Differences?

- ... The lower edge of the cuff was about 1 inch above the bend of the elbow. The cuff was inflated quickly to about 160mm Hg; next, the valve of the cuff was opened slightly, allowing the pressure to slowly fall. A standard stethoscope was used to determine blood pressure. The measurer then placed the bell of the stethoscope firmly on the brachial artery of the arm being measured. As the pressure falls, the reading when the sound of blood pulsing was first heard was recorded. This was the systolic pressure....   [tags: systolic blood pressures]

Factors Affecting Blood Pressure Essay

- Blood pressure is effected by external and internal variables. Internal variables such as age, gender and heredity can not be changed. External variables such as exercise, reduced stress, and healthy diet can significantly improve blood pressure. Regular exercise can reduce blood pressure and help manage weight and stress. External factors gone unmanaged can cause hypertension that can lead to death. In the average human, the heart beats sixty to seventy times per minute. Each time the heart beats, it pumps blood....   [tags: Health]

Manual Blood Pressure Techniques Essay

- ... They are similar to mercury sphygmomanometers in that they both have an inflation/deflation system, an occluding bladder, a cuff and both measure blood pressure by ausculation with a stethoscope to listen to Korotkoff sounds (O’Brien, 2003). They are portable which makes them vulnerable to physical damage causing them to be less accurate in their measurements (A’Court et al, 2011). It is for this reason that aneroid devices need regular maintenance and calibration (Buchanan, 2009). In a cross-sectional observational study, mercury, aneroid and digital sphygmomanometers were tested for accuracy (A’Court et al, 2011)....   [tags: white coat phenomena]
