With hindsight, it’s easy to see the roots of my sleep issues.
After college (almost 30 years ago now…yikes!) I found a part-time job in my chosen field of radio, which required working a 2am-10am shift. It was located about an hour’s ride from my parents’ home, where I lived. I did that for a few months (and worked another part-time gig as well) before being offered a full-time position at the same station. This involved a 6pm-2am shift. I took it and commuted for a few months until I found an apartment nearby.
About nine months later I was promoted (?) to the 2am-10am weekday shift. Although the commute was down to about 15 minutes, the shift wreaked havoc on my circadian rhythms. But I was young and managed to adjust. I also tried to keep a fairly normal schedule on weekends.
I also developed the ability to fall asleep at any time and in any place. It was under control…I never felt like I would fall asleep without intending to do so. Just chalked it up to the crazy work schedule.
Eventually I moved on to another radio station. This time it started with a mid-morning-to evening shift with an occasional meeting to cover at night. Much more in line with the rest of the world. Later, I was given the morning host/anchor duties, which meant getting up at 3:30am to get to work, and working until 1:15pm or so most days. Back to falling asleep any time, any place.
Fast forward to 1996 and a career change. I was hired as a full-time firefighter in my town. This involved working a 24-hour shift twice per week. Obviously, that included some downtime at the station, but I was required to respond to emergencies at all times of the day and night. While off duty, I could also respond as needed…often in the middle of the night. Everyone likes overtime, right?
However, my wife started to comment on my snoring. I didn’t think too much about it, and it was not much of an issue. With being away two nights a week (more if covering an open shift) it never seemed like anything to worry about. Later, a promotion resulted in changing to a day shift and being home every night. It took about a year to feel normal after the change. The comments about the snoring became more frequent.
Then, during a routine physical, my primary care provider (PCP) asked if there was any reason to think I had sleep apnea. I remember being somewhat surprised by the question. I knew apnea involved not breathing for a period of time, and my wife had not said anything like that. I had no reason to think that was the case. So I said no.
Time went by and the talk about snoring became more frequent. At the same time I began to find myself awake at various points during the night. No rhyme or reason to it…just would suddenly be awake. Very infrequently, I would awaken to a feeling of claustrophobia. The feeling would dissipate almost immediately, especially if I got up to use the bathroom. I had never been claustrophobic before, and as a firefighter we routinely do claustrophobia-inducing things, so it had never been an issue. I attributed it to stress and didn’t think a lot about it. Besides, it didn’t happen very often.
Other times I would awaken in the morning with a low-grade headache. More stress? It would go away after 10 minutes or so. My exercise program had taken a bit of a hit as I had little energy in the mornings, but I managed to muddle through. But I could always chalk it up to something else…the fire pager went off twice last night, the cat sat on my chest, etc.
Then my wife started saying I sounded like I was choking at night…and more than once she ended up on the couch because of the noise.
I had little energy in the morning, but after two cups of coffee (big ones!) I would get through the day. But I was getting regular exercise and an annual physical, which typically ended with the doc and/or technicians commenting on how healthy I was.
I’m not sure exactly what made the lightbulb come on last fall. I had the sudden realization that somehow this was all related. After finally putting two and two together, I went to see my PCP, and he agreed. I left with a referral to a sleep clinic.
The clinic was an experience. It’s set up like a small private hotel room. On arrival the technician reviewed the plan and set me up. About 18 electrodes were attached to my head. Two straps around my chest to measure breathing. Electrodes on my legs. A camera on the wall to record my movements. Finger probes. Then the instructions…go to sleep. We’ll wake you if there’s a problem. Easy for you to say, pal.
I slept…at least a bit. Seemed like it took forever to fall asleep while hooked up to all that stuff. In the morning I asked the technician who had to unhook all of it if he saw anything to be concerned about. His response: “I can’t tell you anything official…but you’ll be back for your CPAP (continuous positive airway pressure) machine.” Probably should have seen that coming.
As expected, the sleep clinic diagnosed moderate sleep apnea. By that time I was resigned to it and had done a bit of research on line. The total freak-out came in the fine print of the sleep study report. As a firefighter/EMT, I have some familiarity with vital signs. Oxygen saturation (O2 sat) is a measure of the relative amount of oxygen attached to the hemoglobin in one’s bloodstream. Perfect is 100%. Most non-smokers have an O2 sat of 96-99%. Smokers and people with respiratory disease may run 90-95%. My sleep study report said my O2 sat had dropped to 81% at one point. In the field, if we have a patient with an O2 sat of 81% we start calling for medflight helicopters. I guess that explains the headaches.
I was prescribed a CPAP machine, which I now use nightly. It forces air into the airway under enough pressure to overcome any obstructions like overly relaxed muscles (the sound of breath passing relaxed airway muscles is snoring). I’m still getting used to sleeping with a mask on my face, but it seems to help tremendously. I have had a noticeable improvement in alertness. Although it often takes many weeks of treatment to “rebuild” a broken sleep cycle, I am very encouraged by fewer aches and pains, more energy during workouts, and that urge to nap after lunch is just about gone. My energy level seems much more steady throughout the day.
I also feel my job performance is improving as my mental acuity improves. Again, it’s one of those things that sneaks up over time and you didn’t realize it’s a problem until it’s being fixed. Having said that, I am extremely grateful that I have not been responsible for getting one of my firefighters hurt or worse while my brain was fogged up. My wife says there is no more snoring and choking. The only issue…since the mask is vented, if I turn on my side facing her she gets a wind chill. It’s been two weeks on CPAP, and I follow up with the sleep clinic next week.
Only now that it’s being treated am I realizing how big an impact my sleep problem had on my health. It seems as it creeps up on you, you slowly adjust to feeling tired all the time. It becomes the norm. I had pretty much chalked it up to aging. Having long had the ability to fall asleep any time, it took quite a while to realize that what was happening was actually a sleep problem. With sleep apnea, it’s not that you can’t sleep at all; it’s that you never quite get to the most restful phase of sleep. Before last fall, if you had asked me how I slept at night I would have said “like a baby” and believed it.
As I mentioned, I run and go to the gym regularly, which I can only assume probably kept the worst of the symptoms at bay for longer than otherwise. Like most people, I could stand to lose a few pounds, but it appears in my case sleep apnea is mainly a heredity issue.
Please don’t feel badly for me…there are plenty of people with much more serious problems than mine. But if any of this hits home with you, get it checked. Today.
