As individuals suffering from depression are made aware of the power of a good night’s sleep, they can purposefully embrace sunlight during the day and they can learn to stop avoiding the darkness at night. When circadian rhythms are balanced, natural light triggers the release of serotonin, ...
The scientists said their discovery of the link betweencircadian rhythmsand Parkinson's—a disease characterized by loss of control over movement, balance and other brain functions—suggests these circadian disruptions may reflect neurodegenerative disease processes already affecting the brain's internal cloc...

What are the consequences of these challenges to our circadian rhythms? Obviously, people will feel more tired when they cannot get the right quantity and quality of sleep. However, a growing body of research suggests that the effects on our bodies and brains can be much more serious. ...
In mammals, constant light has been reported to induce circadian disruption, fatigue, irritability, depression and anxiety [9, 10]. In searching for the underlying mechanisms, many studies focus on melatonin, a hormone secreted by the pineal gland in response to the external light cues [11]. ...
We now propose that SF induces sleepiness via initial and rather selective activation of TNF-α pathways, which then will activate an NADPH-dependent oxidative stress cascade that will ultimately lead to cognitive dysfunction along with anxiety-like behaviors and depression (Figure 7). Figure 7 ...

Normal behavior and physiology depend on a near 24-hour circadian release of various hormones. Disruption in hormone release can lead to various pathologies, including affective disorders like anxiety and depression, and metabolic disorders like diabetes and obesity. ...
