WTF Fun Fact 12432 – Spring Fever

The dawn of spring brings mixed feelings and physical reactions. While some poets have long written about “spring fever” as something associated with romance, pleasure, and good spirits, others find March to be a little more gloomy.

You won’t find a doctor diagnosing you with spring fever, but if you notice a change in mood or energy as the days get longer, you’re not alone.

Many people welcome the dawn of spring weather and the return of sunshine. Their ability to spend more time outside is a mood-booster, and they feel restless to get things done after a long and dark winter. Interestingly, these good moods tend to decrease in the hot summer months.

Other less ideal symptoms of this so-called “spring fever” can include an increased heart rate, appetite loss, and mood swings.

Then there are those for whom spring is a curse and who might think of spring fever as the bad kind of fever. There may be some truth to this as well. Some experience a more depressed mood and lack of energy at the start of spring as their bodies adjust. One theory is that the body has used up so much of its serotonin reserves by the end of winter that it leaves people depleted. The return of sunlight helps re-make this serotonin, but the physical process and the hormonal fluctuations involved can cause lethargy.

Some researchers have even hypothesized that rising temperatures cause blood vessels to expand and lead to a drop in blood pressure, leading to headaches. Then there are the people who suffer from “reverse seasonal affective disorder.” The list of spring maladies goes on and on.

However, fever isn’t typically a symptom of any of these reactions, so spring “fever” is more of a nickname.

And don’t worry, we didn’t forget about the allergy sufferers! For so many of us, spring pollen and the swirling of dust particles that occurs as we open our windows again can be a real downer. While allergies don’t cause a fever either, sinus infections can. – WTF fun facts
