WAKING TO THE LIGHT FROM ELECTRONICS HAS POSITIVE EFFECT: Researchers at Rensselaer Polytechnic Institute find that morning exposure to blue light- the kind that computers and phones give off- may reduce daily stress. Researchers had a group of teenagers sleep for only 4.5-hours three nights, and had them awaken to either dim natural light or blue light. Teens who woke up to the blue light had nearly double the level of cortisol, the stress hormone, as those who woke up to the dim light. A professor from Rensselaer says that elevated levels of cortisol throughout the day have a negative impact on the body, but having a morning peak of the hormone resets your cardiac rhythm, and syncs your body to the day, warming it up for the stresses ahead.
