Tired even after 8 hours in bed? Seven things worth checking after 50
Eight hours in bed isn't the same as eight hours of good sleep — and tiredness isn't always about sleep at all. Here's how to tell what's going on.
You go to bed at a sensible time, you stay there for eight hours, and you still wake up feeling as if you've barely slept. It's one of the most common — and most frustrating — sleep complaints. The good news is that there's usually a reason you can find.
First: sleepy, or tired?
These aren't quite the same thing.
- Sleepy means fighting to stay awake — nodding off in front of the TV, or drifting off as a passenger.
- Tired (fatigued) means weary and low on energy, even when you're not about to fall asleep.
Sleepiness usually points to your sleep. Tiredness can come from sleep — but also from stress, inactivity, medicines or a health condition. Knowing which one you mostly feel helps you know where to look.
Seven things worth checking
1. Time in bed versus time asleep
Eight hours in bed can hide long stretches awake. Waking more often in the night is common after 50, according to the National Institute on Aging. A simple two-week log — when you went to bed, roughly how often you woke, when you got up — often shows that "eight hours" is really six.
2. Snoring and breathing
Loud snoring, pauses in breathing, gasping, morning headaches and feeling unrefreshed however long you sleep can be signs of sleep apnea, which interrupts sleep many times a night without you knowing. A bed partner often notices first. It's common, it's treatable, and it's worth asking your doctor about.
3. An irregular schedule
If your wake-up time swings by hours from day to day, your body clock never settles. A steady wake-up time, seven days a week, is one of the most useful changes you can make.
4. Mornings without daylight
Bright light early in the day helps set your body clock. If your mornings are spent indoors with the curtains half closed, try a short walk or breakfast by the brightest window.
5. Evening alcohol
Alcohol can make it easier to drop off, but it makes sleep lighter and more broken later in the night — so you can spend a full night in bed and still wake up unrefreshed.
6. Medicines
Some medicines can disturb sleep or cause daytime drowsiness — including some over-the-counter "PM" sleep and allergy products. Ask your pharmacist or doctor to review what you take. Don't stop a prescribed medicine on your own.
7. The first half hour
Almost everyone feels groggy just after waking. For most people it fades within the first half hour or so. If you judge the whole day by how you feel in the first ten minutes, give it a little longer — with daylight and movement — before deciding.
When tiredness needs a doctor
The National Institute on Aging advises calling your health care provider if you've been tired or low on energy for several weeks with no relief. See a doctor sooner if tiredness comes with other changes — weight loss, breathlessness, feeling very thirsty, or low mood on most days for more than two weeks. Tiredness has many possible causes, from anemia to thyroid problems to depression, and a doctor can check for them.
