Feeling Tired All the Time? Why Autumn Makes It Worse—and How to Fix It
September marks the beginning of a new rhythm. The days get shorter, the air turns cooler, and summer’s long evenings give way to early sunsets and busy routines. For many, autumn feels like a reset. But for others, it brings something less welcome: persistent tiredness, low motivation, and a foggy mind that coffee just can’t fix.
Book the Tired All the Time Screening
If you’ve noticed your energy dipping lately, you’re not alone. In fact:
-
68% of adults report feeling more fatigued during the first 6 weeks of autumn.
-
Vitamin D levels can drop by up to 50% in September and October due to reduced daylight.
-
Women aged 30–50 are twice as likely to report fatigue caused by iron or thyroid imbalance compared to men.
-
42% of professionals struggle to adjust back to work routines after summer holidays, leading to disrupted sleep and daytime energy crashes.
So why does autumn hit so hard? And how can you know whether your tiredness is just seasonal—or something deeper?
The Autumn Fatigue Effect: What’s Really Happening in Your Body?
As the seasons change, so does your body. Less sunlight means lower vitamin D, which affects mood, immunity, and energy. Shorter days can also disrupt melatonin and cortisol cycles, impacting your sleep and stress response. Add back-to-work stress, irregular meals, and reduced physical activity, and you have the perfect recipe for fatigue.
But here’s the catch: persistent tiredness isn’t always just seasonal. It could be your body signalling something more serious—like iron deficiency, thyroid dysfunction, blood sugar imbalances, or chronic inflammation.
The Hidden Causes of Constant Fatigue
The phrase “Tired All the Time” has become so common that GPs even have an acronym for it—TATT. The most frequent culprits include:
-
Iron Deficiency Anaemia – Affects 1 in 4 women over 30, causing low oxygen delivery to muscles and brain.
-
Vitamin B12 or Folate Deficiency – Leads to poor energy metabolism and nerve health issues.
-
Low Vitamin D – Common in Ireland by early autumn, linked to fatigue, mood changes, and immune weakness.
-
Thyroid Dysfunction – Sluggish thyroid hormones slow metabolism, making you feel drained.
-
Blood Sugar Imbalances – Cause energy crashes and cravings, especially during stressful workdays.
The only way to know for sure? Comprehensive blood testing that looks at all the major energy markers—not just the basics.
