The suprachiasmaticus nucleus clock may not be necessary to align circadian rhythms with the light-dark cycle

Circadian clocks regulate functions ranging from alertness and reaction time to body temperature and blood pressure. A new study challenges and disproves the commonly held notion that light resets the master clock, which then coordinates the other, subordinate clocks. Several metabolic and psychiatric diseases are associated with circadian rhythm and sleep disturbances, and this research opens the doors toward an improved understanding of these disorders.…

Could shift work impair brain functioning?

An old proverb states that hard work never hurt anyone, but researchers may have just disproved this notion in certain cases. A new study suggests that working in shifts rather than fixed hours could lead to impairment of the functioning of the brain. Read the entire article here Somnius entrains the brain to help you fall asleep naturally and awaken energized by emitting Bio-Pulses following…

New Options for Hot Flashes and Night Sweats

The steep decline in the use of hormone therapy has spawned a prevalent but preventable side effect: millions of women suffering in silence with hot flashes and other frequently occurring symptoms, called vasomotor symptoms (VMS) including fatigue, sleep disturbance, depression, anxiety, and impaired short-term memory. According to a study by a Yale School of Medicine researcher and colleagues published in the journal Menopause, the team…

Critical flicker fusion in early detection of Alzheimer’s disease

In March of 2000 S. Curran and J. Wattis published an article titled Critical flicker fusion threshold: a potentially useful measure for the early detection of Alzheimer’s disease. The full text of the article is only available via paid subscription, however, portions of its Abstract are presented below. Most curious though is why after 14 years has this method of diagnosis not become mainstream? All…

Sleep Quality Critical to PTSD Treatment

The effectiveness of post-traumatic stress disorder (PTSD) treatment may hinge significantly upon sleep quality, report researchers at the University of California, San Diego School of Medicine and Veterans Affairs San Diego Healthcare System in a paper published in the Journal of Neuroscience. “The implication is that we should try treating sleep before treating the daytime symptoms of PTSD and see if those who are sleeping…

Shortness of sleep ‘speeds up’ aging of the brain

Shortness of sleep speeds up the aging of the brain in older people, say researchers from Duke-NUS Graduate Medical School Singapore. The research on healthy adults aged 55 years and older, published in the journal Sleep, used magnetic resonance imaging (MRI) and neuropsychological assessment to investigate changes in the brain associated with aging. For every hour of reduced sleep duration, the researchers found an annual…

Debate Continues on Hazards of EMR

Everywhere in the modern world, the throb of alternating current generates electromagnetic radiation (EMR) — from the television, the blender, the light bulbs, the wires in the wall. Because the oscillations are very slow (just 60 hertz, or cycles per second), this type of radiation is called “extremely low-frequency.” It was long thought harmless because it is too weak to knock out electrons and directly…

Insomnia could impair memory of eyewitnesses

Researchers from the University of California-Irvine and Michigan State University suggest sleep deprivation could increase the risk of false memory formation – the recall of an event that never occurred. The researchers note that although lack of sleep has been associated with impaired cognitive functioning, very few studies have investigated whether sleep deprivation contributes to false memories, until now. The research team, led by Steven…

Lucid dreamers solve more problems in reality

The movie Inception popularized the concept of “lucid dreaming,” where you wake-up within a dream and are not limited by the constraints of reality. A new study by the University of Lincoln in the UK suggests lucid dreamers are likely to have better problem-solving skills in reality. According to Dr. Bourke, who leads the research team, “It is believed that for dreamers to become lucid…

Want to learn a new dance or yoga posture? Sleep on it!

According to researchers at the University of Montreal, the regions of the brain that play an important role as we train our bodies’ movements interact more effectively after a night of sleep. While researchers knew that sleep helped us learn sequences of movements (motor learning), it was not known why. Read the article A night’s sleep helps us to learn motor sequences from Medical News…
