Causes of Blackouts. The most common cause of a blackout is called syncope, (âsin-co-peeâ). Syncope describes blacking out because of a sudden drop in blood flow to the brain. Usually syncope is so-called âReflex Syncopeâ. This is the cause of fainting. The blackout occurs because blood pressure suddenly drops and the brain is temporarily starved of oxygen and glucose. Although a faint can cause accidental injury, it is not dangerous of itself, provided the patient can lie down flat.
Love is evergreen. Green is everywhere. Itâs the most common color in the natural world, and itâs second only to blue as the most common favorite color. Itâs the color we associate with money, the environment, and aliens, and itâs the color of revitalization and rebirth. Letâs break down our understanding about the color green.
Nature's Colors. Warm colors tend to be those of nature that predominate in everyday lives; orange, red, yellow, green and brown. Sunlight is yellow; orange and red are the colors of fire; both personify the feelings of comfort we get from warm colors. Green sits midway between cool and warm colors and is a combination of yellow (warm) and blue (cool). If it is yellow-based, such as olive green, it becomes warm. if it is blue-based, such as teal, it is cool color. Green and brown are the basic colors of nature upon which all the others stand. While blue is also a color of nature, it is inherently cold because it is the color of ice and northern light. Even at their strongest undiluted values, warm colors tend to imbue feelings of security.
