Why Spring Fatigue Hits Harder Than Winter—and How to Fight It

Many people feel unusually tired as spring arrives. The shift in seasons often brings fatigue, even after the long winter months. Experts point to dietary gaps and increased immune activity as key reasons for this sluggishness. Cold weather forces the immune system to work harder, leaving the body drained by the time spring arrives. This seasonal exhaustion can also stem from reduced nutrient intake during winter. Stored and transported produce loses much of its vitamin content over time, leading to deficiencies that worsen fatigue.

B vitamins play a crucial role in managing stress, supporting immunity, and turning food into energy. They can be found in eggs, whole grains, liver, milk, yogurt, dark leafy greens, and beets. Without enough of these, the body struggles to maintain energy levels.

Iron is another essential nutrient, responsible for carrying oxygen through the blood. A lack of iron often results in apathy, constant tiredness, and drowsiness. Meanwhile, vitamin D—found in fatty fish, dairy, and egg yolks—helps regulate immune function. Low levels of this vitamin are also linked to fatigue.

Magnesium aids in converting food into energy and keeps muscles functioning properly. Good sources include green vegetables, seeds, nuts, buckwheat, and cocoa. A deficiency in this mineral can leave people feeling weak and exhausted. The combination of seasonal immune strain and nutrient shortages explains why spring often feels more tiring than winter. Ensuring a diet rich in B vitamins, iron, vitamin D, and magnesium can help restore energy levels. Without these key nutrients, fatigue is likely to persist as the weather warms.
