Sleep: too little and too much create fat

Written by Science Knowledge on 1:36 AM

SLEEP'S effect on fat is becoming clearer. Having too much or too little piles on the worst kind of fat. Kristen Hairston and colleagues at Wake Forest University in Winston-Salem, North Carolina, monitored 1100 African and Hispanic Americans for five years. Both groups are at a high risk of obesity-related disorders. People under 40 gained 1.8 kilograms more on average if they got less than 5 hours of sleep per night than if they slept for 6 or 7 hours. Those regularly sleeping for more than 8 hours gained 0.8 kilograms more than the medium sleep group. CAT scans revealed increases in visceral fat, which accumulates around the internal organs and is particularly dangerous to health.

About Me

In its broadest sense, science (from the Latin scientia, meaning "knowledge") refers to any systematic knowledge or practice. In its more usual restricted sense, science refers to a system of acquiring knowledge based on scientific method, as well as to the organized body of knowledge gained through such research.

Fields of science are commonly classified along two major lines: natural sciences, which study natural phenomena (including biological life), and social sciences, which study human behavior and societies. These groupings are empirical sciences, which means the knowledge must be based on observable phenomena and capable of being experimented for its validity by other researchers working under the same conditions.
