Before the Body Gets Started -- MEDICA - World Forum for Medicine What exactly happens to our body in case of a spring fatigue?

Prof. Zulley: I think that the reason for spring fatigue is our organism's reaction trying to adapt to a general weather change. When cold days become warmer, the body has to regulate its heat balance. In winter time, humans have a lower core temperature compared to summer. The body begins to warm up during the first spring days, so that blood veins increase their diameter leading to a lower blood pressure. The decrease in blood pressure is responsible that we feel tired and shiftless. How many people suffer of spring fatigue? Do scientifically based figures exist?

Prof. Zulley: I do not know of precise figures. Generally, women suffer more under the seasonal reorientation than men, elderly and adolescents more than children. Certainly people with a general low blood pressure suffer more than others. How can we fight spring fatigue?

Prof. Zulley: As it is a natural adaptation to outer circumstances, it does not help to avoid the weather change by staying at home. In contrary, it is better to expose the body to the new conditions. A person concerned should spend a lot of time outside and exercise in fresh air. That activates serotonin, which is antagonising melatonin, a hormone which is mainly produced in winter days and is responsible for spring fever emotions are. They help to get over the feelings of tiredness.

But, if spring fatigue prolongs over several months, it is possibly an indication for a sleep disorder, a blood circulation defect or another problem. Then, a physician should be consulted. Could you name a special nutrition which can influence spring fatigue?

Prof. Zulley: There are no certain nutritional studies which favour a certain type of food. The recommendation to eat more fruits and vegetables and less food containing carbohydrates and fat is important especially in spring, but valid throughout the rest of the year anyway.
