NEVER UNDERESTIMATE THE POWER OF EIGHT HOURS SLEEP






Sleeping is what mankind can’t do without, as it gives us a sense of refreshment and release of stress. Work, study, and general life style of everyone of use should determine how well we need to sleep in order to get going again, importance of 8 hours sleep should be known to us:

1.You'll learn better.

This isn't just about kids. Adults who get enough sleep do better on tests of short-term memory.
And when researchers had adults do a task once, get a good night's sleep, and then try the task again, they showed improvement. But participants who stayed awake 30 hours after learning the same task had a much harder time improving their skills — even if they practiced and had a chance to catch some recovery shut eye later. Something about the initial sleep deprivation impaired their ability to learn.
Of course, letting kids get enough sleep is important too. In one case, starting schools an hour later (at 8:30 instead of 7:30) increased "standardized test scores by at least 2 percentile points in math and 1 percentile point in reading." The Minneapolis school district found that starting school an hour and a half later (7:15 to 8:40) improved attendance and led to fewer symptoms of depression among students.

 2. People who don't sleep enough are more likely to develop diabetes — even if they are skinny.

 

Type 2 diabetes is an awful disease that can lead to strokes, amputations, blindness, and organ damage. And this isn't just about obesity, so if you are skinny but don't get enough sleep this still applies.
Otherwise healthy adults lose their ability to control blood sugar without getting enough sleep, and the less sleep someone gets, the more likely they are to develop a problem. Compared to adults who sleep seven to eight hours a night, people who sleep six hours are 1.7 times as likely to develop diabetes, and people who sleep five hours are 2.5 times as likely to develop diabetes.

3. People who sleep enough have better moods and fewer problems with depression and anxiety.

People who sleep less tend to have more symptoms of depression, lower self esteem, and more anxiety — though that's an association and it's possible that those symptoms cause people to sleep less.
Still, a review of studies shows that sleep loss has an even stronger effect on mood than it does on cognitive ability or motor function, which is a strong indicator that sleeping more could help.

4. You'll be more productive at work and more focused at home.

The more tired you are, the harder it to concentrate on something, and distraction can take a toll on both work and your personal life. Researchers say that "attention tasks appear to be particularly sensitive to sleep loss." So if you want to focus — either on a job or a conversation — make sure to get some rest.

5. People who sleep enough have fewer heart problems.

One large study found that sleeping five hours or less a night was associated with a 45% increased risk for heart attacks. Keeping people awake increases their blood pressure — even healthy young men who have one bad night of only 3.6 hours of sleep show significant temporary changes.

Know when your food is no longer useful for your body (food spoilage

Image
Spoilage  is the process in which  food  deteriorates to the point in which it is not edible to humans or its quality of edibility becomes reduced. Various external forces are responsible for the spoilage of food. Food that is capable of spoiling is referred to as  perishable food . Food spoilage  results when microbiological, chemical, or physical changes occur, rendering the food product unacceptable to the consumer. Microbiological  food spoilage  is caused by the growth of microorganisms which produce enzymes that lead to objectionable by-products in the food. Chemical  food spoilage occurs when different components in the food react with each other or with some added component which alter the food’s sensory characteristics. Examples of this include: oxidation; enzymatic browning; and nonenzymatic browning. Physical  food spoilage  results when moist foods are excessively dehydrated or dried foods absorb excessive moi...

THE DEADLY BUT UNOTICED DISEASE

Cardiac arrest  is a sudden loss of blood flow resulting from the failure of the heart to effectively pump. Symptoms include loss of consciousness and abnormal or absent breathing. Some individuals may experience chest pain, shortness of breath, or nausea before cardiac arrest. If not treated within minutes, it usually leads to death. The most common cause of cardiac arrest is coronary artery disease. Less common causes include major blood loss, lack of oxygen, very low potassium, heart failure, and intense physical exercise. A number of inherited disorders may also increase the risk including long QT syndrome. The initial heart rhythm is most often ventricular fibrillation. The diagnosis is confirmed by finding no pulse. While a cardiac arrest may be caused by heart attack or heart failure, these are not the same Sudden cardiac arrest is a m...

THE DISTRUCTIVE DISCOVERY

Image
Science has been playing a great role to make our living more easy and more productive and it will continue to do so. A great feature of science is dynamism and science never relent on holding onto that because they believe the only way to develop is through change, change in our housing system, our modes of transportation, communication, health care delivery system, agriculture and food production. I have read a lot of articles and posts where positive reviews and appraisals are been given to scientific and technological inventions, yes, a rosy picture of science and technology but this is not true. People forget to think of is the catastrophic side of these inventions, talking of the deployment of weapons and other instruments of men destruction, atmospheric pollution due to factory and car emission, loss of job due to industrial revolution, man’s dependence on drugs. Narrowly, medicine as a great discovery by science is our case study because at this very age none of us co...
