 Cholesterol Is Not a Disease in Itself Cholesterol is a fat-like substance produced by the liver within the body. It is a vital component of the cells found in human blood. Cholesterol is essential for the formation of healthy cells, Vitamin D, and various hormones—such as estrogen , progesterone, testosterone, cortisol, and aldosterone—as well as for the digestive process. An appropriate level of cholesterol is necessary for the body to perform various physiological functions. The mere presence of cholesterol in the body is not a danger; however, when cholesterol levels rise, the risk of chronic conditions, such as heart disease , increases. What happens when cholesterol levels are high? How can it be controlled? Why do cholesterol levels rise? Factors such as genetics, an unhealthy lifestyle, excessive consumption of processed (factory-produced) foods, obesity, and pre-existing heart disease can lead to high cholesterol. Elevated cholesterol levels can cause blockages in blood ...

 Some Myths and Facts About Cholesterol Cholesterol is a type of fat found in the blood. Simply put, the fat present in the blood is called cholesterol. It helps keep every cell in the body alive. Therefore, the presence of cholesterol in the blood—which is produced by the liver—is a normal occurrence. The liver of an adult produces 1,500 milligrams of cholesterol every day. While the liver generates 85 percent of the cholesterol in the body, the remaining 20 percent is obtained through diet. However, if excess cholesterol accumulates in the body or its levels in the blood become too high, it can cause blockages in blood vessels, leading to serious heart-related problems. This increases the risk of a heart attack. Types of Cholesterol There are two main types of cholesterol: LDL (Low-Density Lipoprotein)—often referred to as "bad" cholesterol—and HDL (High-Density Lipoprotein)—known as "good" cholesterol. LDL is commonly called "bad" cholesterol. Its level...

 Why don't we sleep soundly in a new place? Alcohol consumption helps one fall asleep faster, but it impairs sleep quality and causes early waking. There is an interesting paradox in human life: even when we are away from home for professional engagements, official events, feasts, or celebrations, we do not experience the same sound sleep we get at home. Work pressures while away may fluctuate, but there is freedom regarding food and drink, and plenty of enjoyment. Yet, surprisingly, during those four or five days away, we neither sleep as deeply as we do at home nor manage to sleep in late. When we return home, the workload remains the same, but the moment we reach our own beds, we fall into such a deep sleep that we often don't wake up until late in the morning. Why does this happen? Science and psychology have revealed some interesting reasons. 1. The ‘ First-Night Effect ’ and Brain Vigilance According to psychology, our brain takes time to fully trust a new environment. W...
