Don’t Ignore Winter Fatigue: Could It Be More Than the Cold?

Feeling more tired in the winter is incredibly common. Shorter days, colder weather, and changes in routine can all affect energy levels. But if fatigue feels persistent, overwhelming, or different from your usual “winter sluggishness,” RMFP can help you take a closer look.

There are several common—and treatable—health issues that can contribute to ongoing fatigue:

Anemia: Low iron levels or anemia can leave you feeling drained, weak, or short of breath. A simple blood test can often identify the problem.

Thyroid issues: Your thyroid plays a major role in regulating energy, metabolism, and mood. When it’s underactive, symptoms may include fatigue, weight changes, feeling cold all the time, brain fog, or dry skin.

Vitamin D deficiency: Because we get much of our vitamin D from sunlight, levels often drop during the winter months. Low vitamin D has been linked to fatigue, muscle aches, weakened immunity, and low mood.

Depression or seasonal mood changes: Fatigue isn’t just physical—it can also be emotional. Seasonal Affective Disorder (SAD), depression, and increased stress can all show up as low energy, trouble concentrating, changes in sleep, or a loss of interest in things you usually enjoy. These symptoms are common and nothing to be embarrassed about.

Sleep habits and sleep quality: Winter routines can disrupt sleep more than we realize. Less daylight, increased screen time, irregular schedules, or untreated sleep issues like sleep apnea can all affect how rested you feel—even if you’re spending enough time in bed.

The good news is that you don’t have to figure this out on your own. We’ll help identify what’s behind your fatigue and steps toward feeling better. If your tiredness is lingering, worsening, or affecting your daily life, don’t just chalk it up to winter. Listening to your body and checking in early can make a real difference.
