Seasonal tiredness: What causes spring fatigue?

Spring is a season full of growth and fresh life, though many people struggle with fatigue this time of year. So, what is the cause of springtime fatigue?

The exact cause of springtime fatigue has not been scientifically classified. It is suspected that hormones, blood pressure and nutrition play a major role.

Greater amounts of sunlight in spring activate the production of the mood-boosting hormone serotonin in the morning, while at the same time melatonin, which is responsible for sleep, is still highly active. The interaction of these two hormones stresses the body, leading to fatigue.

The rising temperatures also impact body temperature and therefore blood pressure. When it gets warm, blood vessels dilate and blood pressure drops. The result is fatigue.

Heavier winter diets play a role in physical well-being in the spring. Many people eat too little fresh fruit and vegetables in winter — as a result, a deficiency of valuable vitamins and minerals develops.

Additionally, the time change in spring can lead to tiredness and fatigue, adding another layer to the spring effect when it takes place later this month.
