The alarm clock in you

Human beings have their own natural alarm clocks which can be set subconsciously just by anticipating the time we want to wake up. Research conducted by scientists at the University of Lubeck in Germany has found that people release hormones before waking which help them to anticipate the "stress" ...

Reindeer Provide Valuable Insights Into Sleep Disorders

...r methods of indication, in addition to their body clocks would be required for effective adaptation of these animals to the alternating extremes of light and darkness. An analysis was done on two different species of reindeer; Rangifer tarandus platyrhynchus that lives in the Arctic archipelago of Svalbard...

Sunglasses Can Really Pull a Fast One on the Biological Clock, and Set a Lag in the Build Up Of Jet Lag

... have discovered that people can adjust their body clocks to different time zones by adjusting their exposure to light. The biological clock, when disturbed causes jet lag, which is felt as fatigue, sleepiness and muscle incompetence. Edinburgh Sleep Centre initiated a study for British Airways that monit...

Incorrect Recording Of Response Time By Six Ambulance Trusts

...tment of Health, incorrect data management and the clocks on different servers not being synchronized which meant that time taken to respond was not calculated correctly," it added. Health Minister Lord Warner said, "the Department of Health takes misreporting of NHS performance data extremely seriously ...

Model of Internal Clocks Reveals How Jet Lag Disrupts the System

...not more than four hours, thus allowing the body’s clocks to remain coordinated. The work also has implications for rotational shift workers, such as nurses and airline attendants, as some shifts will be much harder for the body to adjust to than others. The body’s sleep and wakefulness patterns are just t...

Risk of Autism High in Children Born to Fathers over 40 Years of Age

... fact that men were controlled by their biological clocks with respect to having children was proved further during a study of 130,000 children in Israel. Dr Abraham Reichenberg, one of the research team, said: "The sample size for the over-50s was small, so we added it to the result for fathers aged over...

Chronotype, a Measure to Assess Patterns of Daily Activities

...gen, in The Netherlands. Because our watches and clocks are set according to time zones, which are constant over multiple longitudes, rather than according to local sun time, which continuously changes across longitudes, there is often a discrepancy between the natural-light cues one receives as a result ...

Researchers Investigate Gene Linked With Circadian Liver Clock

Reset Your Biological Clock and Prevent Heart Attack!

...ciate that this “master clock” also interacts with clocks in almost all types of tissues. Using mice in which the function of major clock genes have been disrupted, the investigators found distinct and complimentary effects on blood pressure and its circadian variation. What’s more, genes relevant to the ...

Clock Gene Plays Role in Weight Gain, Study Finds

...come a major issue in modern society. Biological clocks are the bodys internal timekeepers that regulate organs and activity/rest cycles by controlling energy levels, alertness, growth, moods and the effects of aging. Research in this field has many health implications for dealing with aging, jet lag, sle...
