Exercise in Morning or Afternoon to Shift Your Body Clock Forward
A new study reports the time of day at which you exercise can shift your body clock. The findings suggest exercise could counter the negative health effects associated with shift work and jet lag.... Read More...
Brain Connections That Disadvantage Night Owls Revealed
A new MRI study reveals those who get to sleep and wake up late have lower resting brain connectivity in regions associated with the maintenance of consciousness. Researchers report the reduced brain connectivity is linked to poorer attention, slower reactions and increased daytime sleepiness.... Read More...
Shedding Light on the Body Clock’s Link to Mental Health and Disease
According to a new study, those who are genetically predisposed to be early risers have a lower risk of developing psychiatric conditions, such as depression and schizophrenia, as well as having better over all health. In contrast to other studies, researchers did not find a strong link between circadian rhythm and diseases such as obesity or diabetes.... Read More...
Sleep Deprivation Accelerates Alzheimer’s Brain Damage
A new study reports sleep deprivation increases the levels of tau, and accelerates the spread of the protein, in the brain. The findings reveal a lack of sleep alone may help drive the development of Alzheimer's disease.... Read More...
How Fasting Can Improve Overall Health
Researchers report fasting affects the circadian rhythm of the liver and skeletal muscles, allowing them to rewire their metabolism. The study suggests fasting can help improve health and protect against aging related diseases.... Read More...
