Do you feel energized, restless and impatient? You may have spring fever. Are you irritable, weary, listless and unable to concentrate? You may have spring fever. Or are you in a constant state of tiredness and exhaustion? It may be spring fever as well. Why so many different symptoms that even seem to contradict each other? It can be your body's reaction to the changing seasons, or seasonal affective disorder (SAD), as the phenomenon is sometimes called.
During the winter months the body protects itself against lower temperatures and reduced sunlight by adjusting its metabolism and hormonal balance. Body temperature drops, blood pressure rises, and secretion of the sleep hormone melatonin increases, making us more sleepy. As the weather gets warmer and sunnier in the spring, the opposite happens: body temperature goes up, blood pressure goes down, and the feel-good hormone serotonin begins to dominate.
The problem is that the transitions between these different stages don't always go smoothly. In any case, hormonal imbalances take place that can cause all sorts of physical and mental responses. Some experts say that spring fever or spring fatigue are a bit like having a "hangover" after a period of dormancy, perhaps a lighter version of what hibernating animals go through.
Because our experience of seasonal changes has become so much mitigated through artificial light and heating, our natural reactions may be even less predictable.
In addition, weather conditions can fluctuate to a larger degree in the spring than at any other time of the year. Global climate change may only intensify these variations. Extreme weather changes have become the new normal in recent years. 2012 had the warmest spring on record in the United States, with over five degrees above average. It also had some of the coldest winters months. As I write this article, temperatures at the east coast are approaching 90 degrees, while western states like Colorado report freezing conditions.
The effects of seasonal changes on the body's equilibrium are stress-producing, says Karina Seizinger, a homeopath and yoga teacher who recommends taking a number of measures for the treatment of spring fatigue symptoms. Among them are eating a healthy, balanced diet consisting of lots of fresh fruits and vegetables, drinking plenty of water, exercising, exposing the body to sunlight and engaging in calming practices like yoga and meditation.
"First and foremost, just be aware, and know that your body is in a state of transition," she emphasizes. "Be kind and patient with yourself, and give yourself some time to adjust."
While feeling fatigued for some time due to seasonal changes is no cause for concern, chronic tiredness may have other roots. Feeling drained or exhausted from stress or lack of sleep can be a normal response. It can also be a sign of a more serious physical or mental condition that should be examined by a doctor.
Outside of that possibility, getting enough sleep, watching your diet, exercising, managing stress and avoiding alcohol, nicotine and drugs should get you back on track for the coming summer.
