More CPAP

Today's the shortest day of the year in the Northern Hemisphere. From tomorrow the days will start getting longer which is just as well.

We were woken at about 3 am by alarms being sounded by neighbouring settlements (but not ours). A ballistic missile had been fired by the Houthis and landed somewhere in south Tel Aviv. Quite why the alarms were sounding in our area is a mystery as that landing site is nowhere near us. Maybe there was the fear that debris from the missile could land in a wide area. As our bedroom is also the security room, we didn't have to get up and run for cover elsewhere.

Saturday morning is the time when I extract the data card from my CPAP machine and look at the data from the past week. Since receiving a new mask¹ at the beginning of November, the average number of apneic events has dropped dramatically: over the past week, six days had no apneic events, and the seventh day had only one event (per hour). Not only that, the 'deep sleep' count for every night last week didn't drop below 46 minutes (apart from last night, when it was 'only' 25 minutes: maybe being woken suddenly in the middle of the night affected this). On Thursday night, I remember having many dreams, and the deep sleep value for that night was 82 minutes, so maybe there is some correlation between deep sleep and dreams.
