I’ve been tracking my sleep, using an Ōura Ring for the past six years and I’ve certainly tried many different things to see if I can improve my sleep. Of significant benefit are blue light regulation so early in the morning, more blue light than after sunset, and try and synchronise with some local circadian sunset, sunrise times. Sitting out at sunset, then going to bed, massively reduces sleep, latency issues and I have a much greater quality of sleep cycles When I’m sleeping outdoors camping, I have some significant shift in Deep Sleep quality, despite perhaps the duration being less as the nights in the summer are often shorter than those in the winter Making the room as dark, as cool as possible have been very beneficial. I found no difference with weighted blankets cooling mattresses or sleep sounds. I’ve tried different sleep postures different pillows the 14° incline that is purported to be of benefit lying on your back. I found difficult and disrupted my sleep despite trying it for around four weeks. Taping works when tolerated but can have a certain anxiety / benefit battle to start with - personally I find sleep posture, myofascial and Breathwork had replaced the need to tape Side lying on your left reportedly has benefits on glymphatic drainage and write sidelined has benefits at promoting parasympathetic nervous system activity through the vagal nerve Reducing caffeine, definitely as a benefit, more on the quality of sleep, rather than amount so better rem quality when either completely cutting caffeine or reducing it after 2 pm Eating close to bedtime again, has a influence on resting heart rate, so I try and aim for this to be at least three hours before I go to sleep Alcohol has a huge influence- and again, I’ve tried this so personally three units and above will affect my sleep quality heart rate variability for the next two days. Supplement wise I’ve tried melatonin which when I’m desperate is a good go to book can often lead to circadian hangovers as I like to terminate affecting my sleep quality for the next few days. I’ve tried GABA I’ve tried CBD I’ve tried a magnesium Complex.
