Springtime is often accompanied by drowsiness and fatigue, which feels not dissimilar to the Monday blues. And now a study suggests that both have much the same causes.
Spring fatigue is mainly thought to be caused by the sun rising earlier and resetting people's biorhythm, which works on 25-hour cycle. It starts ticking every day when the Suprachiasmatic nucleus is stimulated by light entering the eyes.
It is easier for the brain to adjust to the evenings drawing in. But things become more difficult when the sun starts to rise earlier, since bodies have to adjust to a longer daytime.
That is the same reason people feel groggy on a Monday, when they have to face the daylight earlier than at the weekend.
But how to overcome spring fatigue? One of the easiest ways is to avoid waking up too late at the weekend and make sure to get ample sunlight during the morning hours instead of remaining in bed.
