“I’m tired all the time.”
“I have no energy.”
“I’m too tired to go to the gym.”
“I need a nap.”
Walking around in a fog seems like standard operating procedure nowadays. No matter how common it is, though, feeling exhausted, low energy, or sleepy all the time is not normal. It’s always a sign that something else is going on.
Tiredness, Sleepiness, Fatigue: What’s the Difference?
What does it mean when someone says, “I’m tired all the time?” Are they falling asleep at their desk? Do they need to take an afternoon nap in order to function in the evening? Perhaps they feel too wiped out to exercise or even get off the couch?
Colloquially, we use the word “tired” to describe the subjective experiences of both sleepiness and fatigue. “Sleepiness” is the familiar experience of needing sleep due to sleep debt. We all know what this feels like.
Tracking certain things makes sense, if you go for that sort of thing. Tracking step count is hard without a device. No one’s going to count every step they take in their head. You’d quickly go mad doing that. Same with pulse rate and heart rate variability—you could count the number of beats for 30 seconds and double it to get BPM, but that gets unwieldy after awhile and HRV requires a special device. But tracking sleep? On the surface, sleep tracking seems futile and pointless. If there’s anything you should know intuitively without having to measure, it should be whether or not you got a good night’s sleep. You wake up and see how you feel.
Are you groggy? Irritable? Did you just crack an egg into the coffee maker, brush your teeth with light roast beans, kiss your dog good morning and let your spouse out to pee? You probably didn’t sleep very well.
Are you rested? Full of vim and vigor? Can you perform basic bodily functions without requiring a mug of coffee first thing? You probably slept fine.
