(Part 6 of 13 in series, Changes and Results)
Here are a couple more things which I’ve read about, but haven’t tried as part of my sleep hacking.
Some people have suggested keeping a sleep journal. In it you record everything related to sleep: notes about your last meal (what and when), what time you go to bed, when you wake up, perceived quality of sleep, dreams… everything. You would then be able to review this sleep journal periodically and use it to inspire changes in your sleep rituals.
The best way to improve you sleep is to conduct experiments. Change some detail and then sleep with that for a month. Then review your sleep journal notes to compare with the previous month.
In my general life hacking, I was often changing many things at the same time. Some of the details of sleeping which you would hack on with a sleep journal, I was already hacking and tracking.
My Grand-parents’ generation seems to have slept more frequently in separate beds than is popular these days. (A quick search of the Internet leads me to believe as many as 1/3 of couples currently sleep in separate beds on a regular basis.)
I haven’t graduated to this level, yet. But I can tell you that having another person immediately next to you whose movements, or snoring, may wake you, is just another thing to mess up your sleep. When I first started hacking my sleep, I realized that we were waking each other up frequently in the night. It turns out that if I’m only sleeping lightly, the other person’s movements will wake me. But it seems that as my sleep quality has improved, movements and sounds are now much less likely to make me.
That said, if you wanted to try separate sleeping, you could try sleeping on the floor (with futon cushions, or air mattresses.) You could then move your bedding closer or farther apart as the mood strikes, and still be on a solid surface which would not convey any sense of movement from the other person. You’re still close enough, of course, that sounds could be an issue.
Aside: This is one reason why I prefer to sleep on my air mattress on the floor when I travel. Sharing a pull-out sofa or large bed with someone I don’t know, is the worst-case scenario for being disturbed all night.
