Why You May Feel Tired All the Time and What To Do About It

You got eight hours of sleep. So why do you still feel exhausted? If you’ve ever wondered why you’re dragging yourself through the day despite doing all the “right” things, you’re not alone. Fatigue is one of the most common reasons people seek medical advice, and while sleep certainly plays a role, it’s often only one piece of the puzzle. “People tend to think feeling tired is just part of being an adult,” says functional medicine nutritionist Leona West-Fox. “But persistent fatigue is your body’s way of communicating that something needs attention.” The good news? Many of the everyday habits that quietly drain your energy are also the easiest to change once you know what to look for. Here are the first areas Leona assesses with her patients. Let’s talk about blood sugar instabilityMost people don’t connect their afternoon mood crash to what they ate for lunch … or didn’t eat, as is often the case. Blood sugar instability is one of the most common and least recognized drivers of low energy, and it has a very specific signature. “Day to day, it can feel like being fine one minute and suddenly starving, shaky, irritable, anxious, scattered, or exhausted the next,” Leona explains. “It can also look like intense sugar cravings or feeling like you absolutely need coffee to keep going.” The fix is less complicated than most people expect. “One of the simplest things people can do is eat enough food and build meals around protein, carbohydrates, fat, and, ideally, some fiber. A lot of people try to function on coffee and a tiny salad and then wonder why their energy is terrible by 3:00 p.m.” What happens during that 3:00 p.m. crash we’re always talking about?That mid-afternoon wall may be biological. “Our body undergoes a natural transition in our circadian rhythm where cortisol levels come down pretty significantly from the morning,” Leona explains. “When we’ve had enough sleep and enough food, that shift can feel subtle. When we’re sleep deprived and haven’t properly fueled ourselves, it can feel like being hit over the head.” Chronic stress can physically exhaust you.Even when you feel like you have everything on your to-do list under control, you may still be overscheduled, overstimulated, and overdoing it. “You can mentally feel like you’re handling it while your body is still showing signs that the total stress load is too high,” Leona says.
