The heart and blood vessels comprise the two elements of the cardiovascular system that work together in providing nourishment and oxygen to the organs of the body. The activity of these two elements is also coordinated in the body's response to stress. Acute stress — stress that is momentary or short-term such as meeting deadlines, being stuck in traffic or suddenly slamming on the brakes to avoid an accident — causes an increase in heart rate and stronger contractions of the heart muscle, with the stress hormones — adrenaline, noradrenaline and cortisol — acting as messengers for these effects. In addition, the blood vessels that direct blood to the large muscles and the heart dilate, thereby increasing the amount of blood pumped to these parts of the body and elevating blood pressure. This is also known as the fight or flight response. Once the acute stress episode has passed, the body returns to its normal state.

On the other hand, there are instances which show the problems with improved and advanced technology or the solution for one problem with the help of technology is giving rise to another problem. Instead of taking care personally we are sending sms or giving a call on important occasions which were attended personally in olden days. With the use of same internet children are getting addicted to online games and their physical activities and exercises are becoming considerably less. The same social networks are creating rivalry between best friends and couples are getting divorced. The same aviation technology is giving health problems for their workers and creating serious environmental threats. With the heavy usage of fertilizers soil is losing its natural fertility and several varieties of plants became extinct.

The overuse of these sites on a daily basis has many negative effects on the physical and mental health of students making them lethargic and unmotivated to create contact with the people in person. The parents should check and balance on their children when they use the internet. They should be on guard whether they are using it for appropriate time period or not. The peers and teachers should also help students make them aware of the negative effects and explain what they are losing in the real world by sticking to these social networking sites.

“Having an extremely low body-fat percentage can affect the cardiovascular system’s ability to function normally,” says cardiologist Kevin Campbell , ., fellow of the American College of Cardiology. For example, in one study published in the International Journal of Sports Physiology and Performance , when bodybuilders prepared for competition by lowering their body fat, their heart rate dropped to 27 beats per minute. Too-low heart rates, called bradycardia, can lead to dizziness, passing out, and cardiac arrest. Meanwhile, other electrolyte imbalances due to too-low of a body-fat percentage, not to mention caloric intake, can lead to “cardiac arrhythmias and sudden cardiac death," he says.
