It is often said that it is easy to get sick during the change of seasons,'' but this is by no means a matter of imagination. At this time of year, when the temperature difference is severe, the autonomic nervous system that regulates body temperature is working at full capacity, and energy is wasted drastically. As a result, the balance of the autonomic nervous system is disrupted, making it easier to cause symptoms called temperature fatigue’’ such as malaise, headaches, insomnia, and gastrointestinal complaints. This time, we will introduce key points about physical condition management and lifestyle habits to survive the change of seasons in good health.

The most important thing is not to cool your body. Even if it’s warm during the day, the mornings and evenings can suddenly get cold. The basics are to always carry clothing that is easy to put on and take off, such as a thin cardigan or stole, and to frequently regulate your body temperature. In particular, if you are conscious of not getting cold in the “three necks” of your neck, wrists, and ankles, you can effectively prevent your entire body from getting cold.

Next, make sure you get “high-quality sleep.” Sleep is the best medicine to balance the autonomic nervous system. One to two hours before bed, avoid blue light from smartphones and computers, dim the lights in your room, and go into a relaxing mode. Taking a slow soak in lukewarm water (about 38 to 40 degrees Celsius) to warm your body to the core is also an effective way to fall into a deep sleep.

When it comes to your diet, actively incorporate seasonal ingredients rich in vitamins and minerals. Also, try to drink warm tea or plain water rather than cold drinks, and try to follow a gentle diet that won’t put a strain on your stomach or intestines. Fermented foods that improve the intestinal environment (yoghurt, natto, kimchi, etc.) also improve immunity.

The change of seasons is a time when your body is trying to adapt to the new environment. Don’t push yourself too hard, listen to your body, maintain a regular rhythm, and take care of your mind and body.
