The Effects of College Life on the Cardiovascular System

== Human Cardiovascular System ==

Right Atria- One of the four chambers in the heart. This portion of the heart receives oxygen-depleted blood from the rest of the body. The right atrium pumps this blood to the right ventricle. (BZ)

Right Ventricle- One of the four chambers of the heart. This portion of the heart receives deoxygenated blood from the right atria, and pumps it by way of the pulmonary artery to the lungs of the organism.(BZ)

Left Atria- One of the four chambers of the heart. This portion of the heart receives oxygen-rich blood from the lungs and passes it through a valve to the left ventricle. (BZ)

Left Ventricle- One of the four chambers of the heart. This portion of the heart receives oxygenated blood from the left atria and pumps it to the body's tissue. (BZ)

Heartbeat- The rhythm of contractions (systole) and relaxations (diastole) of the cardiac muscle. (BZ)

== Interesting Statistics ==

The Health Education Associates state that before age 60, one in seven American males will have had a heart attack or heart disease (JKA)

The Health Education Associates also state that two of five adults will have high blood pressure (JKA)

== Junk Food ==

(KM)

"If you eat a lot of junk food, you risk putting on weight, which can lead to heart disease and diabetes" - Doug Cluff, M.D. Baylor Medical Center (JKA)

== How Getting Little Sleep Affects Your Heart ==(AJS)

According to an article on WebMD, getting too little sleep, on a regular basis, puts you at higher risk of heart disease. During sleep, blood pressure and heart rate have a chance to rest. Just one night of partial sleep deprivation - between three and four hours of sleep -- caused an increase in blood pressure. However, if sleep deprivation becomes a bad habit, over a long period of time, women between ages 45 and 65, with too little sleep increased their risk of heart attack by as much as 50%.(AJS)

Also the HealthDay Reporter found that compared with those who slept seven to eight hours, those who slept fewer than five hours were 2.5 times more likely to have diabetes. Previous studies showed that people forced to sleep for only four hours a night began to develop problems processing glucose.- (AJS)

== How Stress Affects Your Heart == (JKA)

The word stress has many different definitions and meanings, but in the medical sense stress is a term used to refer to a set of bodily reactions to psychic, physical, infectious, and other factors capable of disturbing the internal stability of an organism (Ferreira 1999). (TMM)

According to the Mayo Clinic, stress creates high levels of cortisol, which can raise your heart rate and increase your blood pressure. It also puts a person at a greater risk for heart disease and stroke. (JKA) Stress increases your heart rate and blood pressure by over-stimulating the sympathetic nervous system.(TMM)

Stress puts fatty acids and glucose into your bloodstream, which is then converted into cholesterol and natural fat. This builds up on the walls of the artery, creating resistence to blood flow and increased blood pressure. (JKA)

== How To Prevent Cardiovascular Stress == (TMM)

According to the British Journal of Health Psyhcology, music can be used as a means to reduce the cardiovascular systems response to stress. In a study aimed at looking at how music effects the cardiovascular system different people were asked to work on difficult math problems in order to induce stress. After a certain amount of time some of these people were asked to sit in silence, others listened to either classical music, pop, or jazz. This study found that out of the four treatments listed above, classical music was the most effective in reducing stress on the cardiovascular system. Sitting in silence was the least effective treatment. This experiment suggests that college students can reduce the cardiovascular systems response to stress by listening to calming and tranquil music. (TMM)
