Study shows how circadian clock mechanisms boost our ability to maintain our bodies when we are most active.
Seasonal affective disorder (SAD) affects over 10 million people in the US. Find out the symptoms and treatment options available.
Study reveals the function of specific immune cells, well documented as playing a significant role in gut health, is directly controlled by our circadian clock.
Glioblastoma stem cells' circadian clocks ramp up the cells' metabolism, making them stronger, more resistant to treatment, and able to divide and multiply more rapidly. By targeting the stem cells with a small molecule drug, researchers found mice models lived longer and their tumors shrank.
Advanced sleep phase may affect as many as one in 300 people, and may be the result of a genetic trait.
Breast milk may help train the circadian clock in young babies. The hormonal composition of breast milk changes throughout the day, with cortisol levels being higher in the morning and melatonin levels being higher at night.
Simple lifestyle alterations can help reset the circadian clock, leading to improved mental and physical health for those who have trouble getting to sleep at night.
Skin and liver cells appear to have their own circadian clock. Both the liver and skin respond to changes in light and maintain critical function, independent of the brain's circadian rhythm.
In pregnant women and mice, the daily schedule shifts a few hours forward during the first trimester. Activity levels also dip during this time. The advance of the daily schedule stabilizes, before gradually returning to normal during later stages of pregnancy.
