The science of yawning
Why we yawn? How yawning works at different levels - blood flows, muscular and skeletal aspects, neurological pathways, social (being rather contagious), etc. - and how those mechanisms help achieve the goal of yawning. It looks like there are no single definitive answer to "why" question and myths about regulating the CO2-vs-O2 balance have been dispelled several years ago, so very interested to hear your thoughts on this topic. Also, interested to know why we DON'T yawn when we sleep.
Achieving consistent state of motivation
I alternate between periods (few weeks to a couple of months) of two binary states - extremely high motivation to do multiple things (side, projects, making music, etc) OR really low motivation where I can barely do anything and only look for short term entertainment like video games and pornography. What would be the best set of protocols to normalize those extremes into a more stable and consistent state?
What do you do when you live in a northern climate and the sun doesn't rise until hours after you are up? (Daylight savings question)
I live in northern Canada.... for parts of the year we see very little sunlight. How can we help our circadian rhythms/sleep if we can't get into sunlight until literally hours after we get up? (I definitely have more energy in the spring/summer/fall months - seasonal depression is definitely a thing). Also, what about time changes? I feel like our time changes always make me feel so much worse. Last fall we actually had a provincial vote on whether to abandon the time changes, but there was only the option to adopt one of the changes, not select between either. Is daylight savings better or not? If we got rid of the time change, which time should we keep (biologically speaking)?
