Circadian rhythms aren’t just about sleep—they regulate metabolism at a fundamental level. When disrupted, metabolic imbalance can contribute to disease, even acting as a signal in cancer development. Restoring these rhythms may offer new therapeutic paths. #CircadianRhythm #CancerResearch

Sleep is essential to every aspect of women’s health — from physical and mental well-being to hormonal balance and long-term disease prevention. Yet many women experience unique sleep challenges that are often underrecognized and undertreated.

The American Academy of Sleep Medicine is committed to advancing research and solutions to improve sleep health for women at every life stage — from adolescence and reproductive years to pregnancy, menopause, and beyond. ♀️ Learn more here: https://t.co/7Z06tEjW9A

As we prepare to spring forward this weekend, we want to remind you of the AASM's position on Daylight Saving Time.

It is the position of the AASM that the United States should eliminate seasonal time changes in favor of permanent ST, which aligns best with human circadian biology. Evidence supports the distinct benefits of ST for health and safety, while also underscoring the potential harms that result from seasonal time changes to and from DST.

@Mickolas9 I actually disagree. We treat mental illness. We treat it with kindness (and good clinical guidelines) and we fight to remove stigma. Homophobia is bad character, no kindness required.

Actigraphy-derived measures of sleep phase variability and activity amplitude identified individuals at higher risk of relapse in #Depression, supporting their potential as scalable biomarkers in ongoing monitoring.

Our paper is out! We identify markers of relapse in euthymic individuals with #depression analyzing 1-2 years (!) of continuous wearable data.

"...could diagnosis confine as much as it liberates?"

On the cover, Daniel Marchalik & Nicholas Mark explore the nuanced role of diagnosis in health and identity.

Should I say... disappointed but not surprised?
To some, this has never been about science. It's a corporate world and a race towards personal gain.

Beautiful project I have the privilege to be a part of. Led by @Tiago_deAndrade, this is all you need to now of the present and the future of Circadian Medicine (in Portuguese!).

If you could not be there in person, here is a little tease. We have been exploring the changes in rest-activity rhythms that happen early in antidepressant treatment. Super cool!😎🤯🧠 #actigraphy #biologicalpsychiatry
