I wish Finland would stop messing around with Daylight Saving Time (started today) and adopt “winter time” as the permanent standard.
If you're in the UK, don't forget to put your clocks one hour forward tonight. And read this fascinating article on how the change to British Summer Time (BST) affects our metabolism.

Daylight savings time shifts our clocks around, but our circadian rhythms are also shaped by the natural world we belong to.
Gaian meditation encourages getting outdoors morning, noon, and evening - to observe, breathe, and reconnect with the real, natural world. A practice good for what one might call our soul, but also essential for our overall health and wellbeing.

Well this seems worrisome: "NPs [Nanoplastics] can infiltrate the circadian rhythm-regulated brain region (SCN), affecting the expression of circadian genes." (Mind you, for now this is only shown in a mouse model.)

@PhDMarie I so appreciate that there's a text summary of the podcast with links to relevant sections, thank you. The section on experiments to study the human circadian rhythm was so fascinating!
"These were the first controlled experiments done with human participants that demonstrated that we have our own internal clocks and that we may have at least two internal clocks."
#TIL that there's a body temperature rhythm that can be dissociated from the circadian rhythm! In retrospect, it makes sense given that (from what I know) lower temperature helps most humans fall asleep easier
This book from Whitrow continues to marvel with a chapter on biological clocks, touching on the role of time keeping in a range of phenomena from bird migration to honeybee dance, photoperiodism in plants, circadian rhytms in fiddler crabs, circannual rhythms in hibernating mammals, deer antlers and in psychotic patients ... easy to forget scientists had found out a lot by 1972. Observation and note taking was (and continues to be) the name of the game. What they were lacking were the molecular mechanisms.
NGL, it getting almost dark at 4 PM is rough after having spent much of my summer north of the arctic circle. Could fall asleep in my car and get a suntan the whole time, but now? It gets so dark and my body is like "huh what is this?". 
How does being outdoors prevent the development of Myopia? (11 June 2024)

- afternoon time outdoors more important than morning
- light intensity
- spectral quality (red)
- dopamine, local effect on eye
- atropine & dopamine do not affect normal eye growth; only have effects once myopic changes are initiated

Why aren't there more epidemiological studies that consider the effect time spent outdoors on health?

Sending this question into the mastodon void:
Has anyone ever used a sun lamp/light therapy lamp at home? And if so, did you find it helpful to your sleep quality/circadian rhythm?
