EVERYONE FEELS TIRED NOW AND THEN. BUT HEALTH EXPERTS CAUTION THAT TIREDNESS THAT SUDDENLY WORSENS OR PREVENTS YOU FROM DOING WHAT YOU WANT CAN BE ‘A CANARY IN THE COAL MINE.’
BUT FIGURING OUT IF THERE’S A PROBLEM CAN BE TOUGH
Tired? Join the club.
Feeling tired or fatigued is a common experience. Yet healthcare providers often dismiss complaints about tiredness — both because the symptom is universal and because it can be challenging to evaluate medically, says Michael Grandner, director of the University of Arizona’s Sleep & Health Research Program in Tucson.
While tiredness is often temporary, treatable or nothing to worry about, experts say that tiredness that suddenly worsens or prevents you from doing what you want can be a sign of a health problem or sleep disorder.
“Sleep seems to be a canary in the coal mine, where it’s sensitive to all these things going on in your body,” Grandner says. “So, when it starts changing, you want to ask, ‘Well, what’s going on?’ ”
Sleepiness, fatigue, tiredness: in conversation, people use the terms interchangeably. But medically, their definitions differ. Understanding the differences is an important first step toward tackling the problem — or figuring out if there is one.
Sleepiness is a need for sleep that makes it difficult to stay awake. Fatigue, on the other hand, is a deeper sort of an inability, either physical or mental, to do what you want to do, such as get to the grocery store.
Somewhere in the middle is tiredness, a desire to rest that is less debilitating than fatigue and less dramatic than sleepiness. You can still be productive while tired.
Whatever you call it, it’s common. In a 2014 survey by the non-profit National Sleep Foundation, 45 per cent of adults said they had been affected by poor sleep or not enough sleep in the previous week. As many as 20 per cent of people report excessive sleepiness on a regular basis. And, a National Safety Council survey reported in 2017 that 76 per cent of people felt tired at work.
If you’re bothered by how tired you feel, there might be some simple explanations, including the most basic: not enough sleep. A third of Americans don’t get the recommended seven or more hours a night, according to the Centers for Disease Control and Prevention. And because needs vary widely, even seven hours isn’t enough for many people.
Sleep deprivation is not just a nuisance. It raises the risk for car accidents and has been linked with health concerns such as Type 2 diabetes, cardiovascular disease and depression.
Lack of sleep can also affect mood and relationships in ways that even caffeine can’t remedy, says Nathaniel Watson, director of the Harborview Sleep Clinic at the University of Washington in Seattle. “There is no substitute for sleep,” he says.
Beware the temptation to lie down exactly seven hours before your alarm is set to go off. Nobody sleeps 100 per cent of the time that they’re in bed, Watson says, so it might take eight hours of pillow time to get seven hours of sleep.
It’s normal to have occasional rough nights because of stress or sleep interruptions. And even if you get a good night’s rest, you may experience a mid-afternoon bout of sleepiness as a result of ordinary circadian rhythms.
Age is something else to keep in mind, though the evidence there is somewhat counterintuitive. Studies show that, as people get older, sleep patterns tend to change in predictable ways. It may start taking longer to fall asleep. You may wake up more often and spend more time awake in the night. And bedtimes and mornings may shift earlier. Menopause is another common cause of interrupted sleep.
But sleep satisfaction doesn’t necessarily drop with age. Studies by Grandner and others have found that complaints about sleep and tiredness actually decline with age after a peak in early adulthood. In other words, you should not blame aging if you find yourself struggling with tiredness.
“Aging is associated with sleep that is a little shallower and a little more broken up, but not less satisfying,” Grandner says. “If you’re an older person and you’re really unhappy with your sleep, that’s actually an issue.”
For people of any age, if tiredness is making it hard for you to get through most days or otherwise getting in your way, experts suggest visiting a primary-care clinic first to be evaluated for common causes, including depression, autoimmune diseases, vitamin levels and thyroid issues.
One warning: The appointment might be frustrating. Many doctors lack training in sleep medicine, Watson says. They also often miss the signs of insomnia or they suggest ineffective treatments for it, a 2017 study found. Insomnia affects up to 15 per cent of adults and, Grandner says, studies show that behavioural therapies work better than medication.
