FOREWORD
Spring is here, get out into nature!

Sometimes we still wake up to a chilly dawn, but winter is slowly fading away and spring is approaching, in line with the natural cycle. Our sight, our hearing, our sense of warmth, our senses all signal the renewal of the outside world.

After the winter calm, buds start to break, fields turn green, trees leaf out, birds nest, bears emerge from hibernation, and all paths in nature lead to renewal after the winter calm.

What can spring bring for us humans? What renewal can we expect?
Our immune systems are sometimes overwhelmed by chronic cold-related illnesses, which break out during the winter, when we are less immune, and we develop vitamin, mineral and trace element deficiencies, cold-related confinement indoors, and limited outdoor exercise. With the arrival of spring, it is not only nature that can renew itself, but also us humans. Despite a steady supply of food in winter, the period is mostly is limited in terms of fresh fruit and vegetables, which is closely linked to a reduced intake of vitamins, minerals and trace elements. For a healthy diet, in addition to other necessary nutrients, it is recommended to consume 400-500 grams of fruit and vegetables and fibre-rich nutrients per day.

Our body's resistance and the strength of our immune system depend largely on our physical activity. The rise in spring temperatures makes it possible to exercise in the open air. Running and hiking boots can be broken in, and we can set off for areas outside towns and villages. For young and middle-aged beginners, start the spring programme with a walk, followed by a jog, increasing the distance and intensity according to your level of fitness. In older age, walking a few kilometres a day is already beneficial for their health.

It is important to check and service bicycles. After cycling shorter distances, longer rides should be undertaken, with adequate hydration and food. The rise in temperatures is favourable for water sports. Our waters offer plenty of opportunities for recreation. From spring onwards, waterway centres in the open waters are open for water excursions with trained guides.

Increased hours of spring sunshine, quality nutrition and regular exercise in nature will ward off spring fatigue and improve the health of body and soul. To this renewal, I wish all our dear magazine readers beautiful spring days and activities!
