Small adjustments for early autumn

When temperatures suddenly fall and rainy days continue in early autumn, you may feel like changing how you spend time at home. Begin with layers, ventilation, warm meals and everyday nutrition. Here are ideas for soup made with familiar ingredients and for choosing foods thoughtfully.

Short sleeves may have felt right only recently, yet a day around 20°C can make a warm bowl of soup appealing. Instead of adding elaborate routines, gradually adjust the room’s air, your meals and the time before bed to how you feel that day.

What can you adjust on a cool, rainy day?

Start with clothing and comfort indoors. The same 20°C can feel different when you are sitting still in short sleeves or moving around doing housework. Keep a light cardigan or lap blanket within reach.

Change out of rain-soaked socks and clothes, and adjust the air conditioning to the room. You do not need to decide by the thermometer alone; simply notice whether you feel cold now.

Even on chilly days, rooms need fresh air. Japan’s Ministry of Health, Labour and Welfare stresses ventilation in every season. Use continuous ventilation systems or extractor fans, and take care to avoid rain entering or the room becoming too cold when opening windows.

On days when indoor laundry traps moisture, check a hygrometer or condensation before adding humidity. Respond to the actual condition of the room rather than the season’s name.

Enjoy a meal, beginning with a warm bowl

When rain makes shopping feel like an effort, try making a warm soup from ingredients already at home. Tofu and mushroom miso soup, or egg and leafy-green soup, fits easily into everyday meals and can be varied with different ingredients.

A basic meal combines a staple such as rice, a main dish such as eggs, fish, meat or soy foods, and a vegetable side dish. When adding soup, consider what the whole meal will contain.

There is no need for many dishes. Frozen vegetables, tofu and ready-made dashi can help you prepare an amount that is comfortable to eat. A pause in front of a steaming bowl can become a small signal to settle into the next part of the day.

Explore traditional food wisdom through familiar ingredients

Yakuzen, a food tradition informed by traditional Chinese medicine, places importance on combining ingredients according to the season and the individual. Here, we draw on that food culture for ideas about seasonal meals and appetite.

A little ginger in your usual soup or yam in rice porridge adds a different aroma or texture. If edible jujubes are available, remove the stones and simmer them until soft to enjoy their sweetness.

Ginger is a familiar ingredient that adds fragrance and a little heat. You do not need rare ingredients or large quantities; begin with an amount you enjoy.

Ginger-scented tofu and mushroom soup: ingredients for two

Tofu, shimeji mushrooms and leafy greens cook in one pot, making this an easy soup for a rainy day. Tofu provides protein while vegetables and mushrooms join the meal. Adjust the ginger and miso to your taste.

  • 150 g tofu
  • About half a pack of edible shimeji mushrooms
  • 1 komatsuna plant
  • 1–2 thin slices of ginger
  • 400 mL dashi
  • Miso: start with about 2 teaspoons, then adjust to taste

How to make the soup

  • Trim the base from the shimeji and separate the mushrooms. Cut the tofu and komatsuna into bite-sized pieces.
  • Put the dashi, ginger and shimeji in a saucepan. Simmer until the mushrooms are thoroughly cooked.
  • Add the tofu and komatsuna and cook further. Lower the heat and dissolve the miso in the soup.

Make it part of an everyday meal

Serve with rice and add other dishes to suit your appetite. You can omit ginger if you do not like it. Aim for a flavour you can comfortably enjoy in your regular meals.

How should you think about everyday nutrition?

When considering nutrients that are difficult to obtain from everyday meals alone, health foods can be one option for supplementing your diet. First review how you usually eat, then consider what you can adjust through meals and what you may need to supplement.

Look beyond prominent claims and check ingredient names, amounts and the recommended intake. For foods with health claims in Japan, read the product’s statements and intended users to see whether it fits your purpose.

  • What do you want to supplement? Compare your meals with the ingredient label.
  • How much will you use? Follow the recommended daily intake and watch for overlapping ingredients.
  • Are there precautions? Check the intended users, allergens and other labelling.

Use health foods thoughtfully

Taking more is not necessarily better, and health foods do not replace medicines. If you take medication, receive medical care, or are pregnant or breastfeeding, consult a doctor or pharmacist before use.

What is semitake, and how does it relate to cordyceps?

Food ingredient lists sometimes introduce unfamiliar names. Semitake is a fungus described as belonging to the wider group commonly called cordyceps. Japan’s Forestry and Forest Products Research Institute explains the relationship between insects such as cicadas and fungi that form mushrooms.

The name “cordyceps” does not mean that everything described by it is the same species or has the same composition. For processed foods, check each product’s ingredient names, parts used, cultivation or extraction methods, and amounts.

Knowing an ingredient’s name is different from establishing that a particular product has a specific effect. Rather than choosing only for novelty, begin by understanding the ingredients used. The OKD Vitalis semitake product page is linked in the references below.

Spend a rainy day at your own pace

After clearing the table, begin preparing for rest a little earlier tonight. Leave one more chore until tomorrow, or set out a cardigan for the morning. Choose a small preparation that makes things easier for you.

Refresh the room’s air, prepare a warm bowl and enjoy your meal calmly. You do not need to change everything at once. Choosing one thing you can do that day is enough.

OKD Vitalis values noticing changes in the seasons and in daily life, and finding comfort that suits you. Let an early-autumn day of steady rain offer a chance to reconsider how you spend time at home.
