Physical Activity versus Extra Sleep
Obesity and overall health can be affected by both the amount of sleep you get, and with the amount of physical activity you do. Increasing your physical activity and the intensity you perform the activity will help fight obesity and improve your overall health. When a person loses weight their overall Active Energy Expenditure (AEE) is reduced, but with a reduced body weight people tend to be more physically active which will overcome the reduced AEE (Bonomi 2013). To reduce health risks a person must do more than just sleep, or be more active. Overall health in obesity subjects also comes down to life style modification and helping them maintain proper nutrition reducing Cardiovascular Disease Risk Factors (Strasser 2013). While sleep is important it has minimal effects on nutrition, and minimally effects doing more or less physical activity. Physical activity has a more powerful effect on obesity and overall health concerns.
Having more intake of energy than output will cause weight gain and obesity. With our modern lifestyle consisting of a lot of sedentary time and reduced physical activity obesity can be the result. Many factors such as weight displacement during physical activity goes into the amount of AEE (Bonomi 2013). A study of patients with a BMI > 27kg/m2 shows that after energy restriction of patients body weight was reduced by 14kg ¬± 5kg and though AEE was down after weight loss the amount of time being sedentary was reduced adding +11 ± 21 min walking, and + 4 ± minuets bicycling. (Bonomi 2013). Increasing ones physical activity levels reduces the risk of having a high blood pressure, which improves health and reduces risks associated with obesity (Strasser 2013).

Obesity is a health problem which is growing very rapidly all over the world. Current health articles such as this one, are emphasizing the importance of diet and exercise, to keep a healthy body weight, and to avoid obesity and its consequences at all costs. It is extremely important to make sure one is maintaining a good body weight in order to avoid other complications later on in life.
Obesity is a very complex condition as there are many physiological and psychological dimensions to it. The complications accompanying the disease are multiple and are associated with the increased risk of many other medical conditions. It is thought that we live in an obesogenic environment due to an interaction of environmental, developmental and cultural influences. With the main cause of the disorder thought to be due to a combination of a sedentary lifestyle accompanied by an increased consumption of poor quality food with a high calorie and sugar content. The lack of energy expenditure could be explained by many individuals working a large number of hours, most days of the week in jobs that require minimal physical activity and it is often difficult to accomplish the recommended ...

...al conditions of cardiovascular disease that have been linked to obesity, including strokes, coronary artery disease, congestive heart failure and arrhythmias. All of these conditions can be improved or prevented by the individual losing ten percent of their body weight. Physical activity also plays a crucial role in cardiovascular disease. Studies have shown that the greater the amount of physical activity, the less the chance for developing cardiovascular disease, even when other factors, such as Framingham’s scale, are accounted for. Regarding future research, a study further researching genetic and environmental links to cardiovascular disease would provide helpful information. Also, research studying the effects of physical activity after the onset of cardiovascular disease could be beneficial to determine if physical activity can improve patients’ conditions.

A number of health –related behaviors contribute remarkably to the onset cardiovascular disease. Smokers are two times as likely to have a heart attack as non-smokers, and one fifth of the annual 1,000,000 deaths from CVD can be attributed to smoking. A sedentary lifestyle increases one’s risk of heart disease. However, America remains predominantly sedentary, and more than half of American adults do not practice the recommended level of physical activity, while more than one-fourth are completely sedentary Between 20-30%, approximately 58 million people, of the nation’s adults are obese. Obesity severely increases risk for hypertension, high cholesterol, and other chronic diseases which have been proven to cause heart disease. As one can clearly see cardiovascular disease is a very broad topic encom...
Although many individuals are uncertain about the increasing statistics associated with obesity, more than seventy percent of men and virtually sixty-two percent of women within the United States adult population are overweight or obese (Wilmore, Costill, & Kenney). Obesity refers to the condition of having an excessive amount of body fat. If an individual’s amount of body fat becomes too excessive, he/she is at a much greater risk of developing life-altering diseases such as heart failure, hypertension, type II diabetes, cancer, gallbladder disease, osteoarthritis, etc. (Wilmore, et al., 2008).
Obesity is a physiological condition characterised by an excessive accumulation of body fat, specifically the build-up of adipose tissue beneath the skin. In recent years, the number of people diagnosed with clinical obesity has increased dramatically, with governments desperately trying to tackle the obesity epidemic and its associated consequences (McLannahan and Clifton, 2008). Studies have found that the prevalence of obesity once stood at an estimated 9.8% (Kelly, Yang, Chen, Reynolds & He, 2008), a considerable figure representing almost 400 million individuals worldwide. Even though obesity has now been recognised as a major problem the number of people affected is increasing rapidly, with almost 300,000 deaths attributable to obesity in the USA each year (Allison, Fontaine, Manson, Stevens, & VanItallie, 1999). Excessive amounts of fat can prove dangerous as the condition has a very high comorbidity rate with other long term health issues such as diabetes, cardiovascular disease, hypertension and cancer (Pi-Sunyer, 1993). Numerous examples of media, medical journals and educational literature concerning obesity refer to the condition as a disease, with an increasing use of the word ‘Epidemic’ to describe the somewhat recent surge of obesity cases in western societies (Boero, 2007), however there is little material available that offers evidence for obesity meeting specification for disease. Instead it has been proposed that obesity is alternatively a risk factor for developing other potentially harmful diseases, influenced by a variety of other factors i.e. genetics, cultural ideals and biological impairments.
Obesity: Our weight also depends on our sleep duration. Studies show that people who slept for 9-10 hours are more likely exposed to obesity compared to those who slept between 7-8 hours. Even when food intake and exercise were taken into account, this link between sleep and obesity stayed the same.
With obesity can come many other diseases or health problems. For example, people who are obese are more likely to develop heart problems, diabetes, or high blood pressure (Loop).... ... middle of paper ... ...

Sleep is a very important factor in the human function. Our body and brain is able to reset itself and rejuvenate while we sleep. When we do not get the required amount of sleep, we start to feel lethargic and foggy minded, because our mind and body wasn’t able to replenish itself. Sleep is imperative that an insignificant rest deficiency or lack of sleep can affect our ability to remember things; decisions and can affect our temperament. Chronic sleep deficiency can get the body to feel agitated and it could lead to serious health problems such as, heart problems, stress, acne, and obesity.
Obesity occurs in all countries and it is one of the gravest problems in modern society. Obesity problems have become one matter of concern for individuals all around the world. What is more is that Obesity rates continue to rise all around the world. One of the chief causes is unhealthy diets. Obesity is also due to lack of exercise and lack of education and awareness. Therefore obesity has various effects including the risk of suffering from a range of health conditions, increased expenditure on health care and lack of self-esteem.
