01. It is a complete myth that stress can turn hair gray, it can cause hair loss. In fact, hair loss can begin up to three months after a stressful event.
02. In recent studies, the top most stressful jobs are a surgeon, commercial airline pilot, photojournalist, advertising account executive, and real estate agent. The least stressful jobs were actuary, dietitian, astronomer, systems analyst, and software engineer.
03. The top three stressful cities in America are Chicago, Illinois; Los Angeles, California; and New York, New York.
04. Stress can make acne worse. Researchers say stress-related inflammation rather than a rise is sebum (the oily substance in skin) is to blame.
05. Laughing lowers stress hormones (like cortisol, epinephrine, and adrenaline) and strengthens the immune system by releasing health-enhancing hormones.
06. The stress hormone cortisol not only causes abdominal fat to accumulate, but it also enlarges individual fat cells, leading to what researchers call “diseased” fat.
07. Stress is linked to the six leading causes of death: heart disease, cancer, lung ailments, accidents, liver cirrhosis, and suicide.
08. An early record of post-traumatic stress syndrome dates from the eighth century B.C. in Homer’s Iliad when Achilles suffers severe battle stress in the Trojan War. Achilles complains of feeling emotionally “numb” or “dead” and expresses suicidal thoughts and rage.

15. Pupils dilate (mydriasis) during stress much the same way they dilate in response to attraction: to gather more visual information about a situation.
16. Chronic low-level noise and low-frequency noise below the threshold of human hearing provoke stress hormones that can interfere with learning and can also elevate blood pressure, degrade the immune system, and increase aggression.
17. Studies have found that women with moderate levels of stress were at lower risk for suicide than those women who had very high or very low levels of stress.
18. Scientists suggest that stress is part of the evolutionary drive because it has enabled humans to survive. Specifically, it temporarily increases awareness and improves physical performance.
19. Stress makes the blood “stickier,” in preparation for an injury. Such a reaction, however, also increases the probability of developing a blood clot.
20. Research has shown that dark chocolate reduces stress hormones such as cortisol and other fight-flight hormones. Additionally, cocoa is rich in antioxidants called flavonoids.
21. Chronic stress increases cytokines, which produce inflammation. Exposure to constant inflammation can damage arteries and other organs.
22. Stress can alter blood sugar levels, which can cause mood swings, fatigue, hyperglycemia, and metabolic syndrome, a major risk factor for heart attack and diabetes.
23. Chronic stress worsens irritable bowel syndrome (IBS), a condition that irritates the large intestine and causes constipation, cramping, and bloating.
24. When cells shrink due to exposure to stress hormones, they disconnect from each other, which contributes to depression.
25. Chronic stress decreases the body’s immune system’s response to infection and can affect a person’s response to immunizations.
26. Stress can increase the ability of chemicals to pass the blood-brain barrier, which shields neurons from some poisons, viruses, toxins, and other fluctuations in normal blood chemistry.
27. Acoustic stress (caused by loud noises) can trigger an episode of LQTS (Long QT Syndrome) , a disorder of the heart’s electrical system. LQTS is estimated to cause as many as 3,000 deaths in the U.S. each year.

29. Stress increases the risk of preterm labor and intrauterine infection. Additionally, chronic levels of stress place a fetus at greater risk for developing stress-related disorders and affect the fetus’s temperament and neurobehavioral development.
30. Post-traumatic stress physically changes children’s brains; specifically, stress shrinks the hippocampus, a part of the brain that stores and retrieves memories.
31. Chinese stress balls (Baoding balls) were created during the Ming dynasty (1368-1644) in Baoding, China. Originally made of iron, the balls are thought to relieve stress because they touch pressure or acupuncture points on the hand.
32. Stress can result in more headaches as a result of the body rerouting blood flow to other parts of the body.
33. The hyper-arousal of the body’s stress response system can lead to chronic insomnia.
34. Extreme or sudden emotional trauma can lead to BHS (Broken Heart Syndrome), or stress cardiomyopathy (severe heart muscle weakness). This condition occurs rapidly and usually in women. In Japan, BHS is called “octopus trap cardiomyopathy” because the left ventricle balloons out in a peculiar shape.
21. Cool your room down to between 60 to 67 degree Fahrenheit (16 to 20 degree Celsius) for the best quality sleep.
