Rest Easy

For some reason, human beings spend a third of their lives asleep. For the lucky few for whom sleep comes easily, bedtime is a blissful part of life. Unfortunately, 40 percent of Canadians report at least one feature of disordered sleep every week. That’s why insomnia is one of the most common reasons for visits to the family doctor and  costs a huge amount of money in lost productivity.


Experts used to think that insomnia was simply a symptom of another medical illness, such as depression or chronic pain. We now know that it can actually be a disease unto itself with its own constellation of consequences.


Beyond making you feel lousy, poor sleep is associated with depression, anxiety and cardiovascular disease in the long term. We also see higher rates of substance abuse in people with insomnia, possibly because they’re using drugs and alcohol to get to sleep. Despite the magnitude of the problem, we still have very limited resources for dealing with insomnia. That said, most people can find some relief by adopting a few simple strat­egies—and sticking to them.


My first recommendation is to start a sleep diary (templates can be found online). These diaries can help clarify the severity of the problem. They act as a baseline, so  the effect of various interventions can be tested objectively.


I typically avoid using medication for insomnia unless absolutely necessary. I focus on what is called “sleep hygiene” or the pattern of behaviours as we wind down the day. Preparing for a good night’s sleep begins during the day. It’s important to avoid caffeine after lunch. That means paying attention to the additives in workout supplements and energy drinks. Stay away from alcohol too close to bedtime, as it might help you get to sleep but often you’ll wake up in the middle of the night as its effects wear off. I recommend moderate exercise every day, but not too late in the evening. And quitting smoking goes without saying.


Another thing to remember: A bed should be used only for sleep and sex. Working, reading or Facebooking there suddenly turns the bedroom into a place for thinking, not relaxing. Light-emitting screens can trigger a daylight response, tricking your brain into thinking it’s time for work. Read before going into the bedroom and get into bed only when you’re ready for sleep. Forcing yourself to sleep is an exercise in frustration. If you’re lying in bed for more than 20 minutes without falling asleep, get up and move to a different room to do a mundane activity. That doesn’t mean rewarding yourself with TV or a snack: Go read something boring or listen to calming music.


It’s important to get up at the same time every day, even if you’ve had a bad night of sleep or it’s the weekend. You may be exhausted for the day, but the next night you’ll fall asleep more easily. Once awake, get out of bed immediately and avoid napping during the day. Some people encourage napping for alertness, but poor sleepers don’t have that luxury: It’s more likely to make sleeping even tougher later on. Consider meditation as an alternative.


If these strategies fail, a short course of a sedative or hypnotic is the next step. These drugs work   well in most people but should  be used intermittently and for short periods since they can cause dependence. We’ve also seen recently that there might be a link between sleeping pills and memory impairment. To get around that, and for people who need a longer-term solution, some doctors will instead prescribe sedating antidepressants at very low doses to help with sleep.


There’s nothing like a full night of deep sleep to feel recharged. Alas, for some of us, such sleep is rare. Sleep science is still very new, and, although we have limited treatment options now, I see things rapidly changing.


Until a breakthrough, I like to remind my patients not to worry too much about sleep. Sure, it’s frustrating when it won’t come, and there can be some long-term consequences. But a few rough nights of sleep is never dangerous.
