Precautions for Forest Bathing (Shinrin-Yoku) – Part2



Part 2 – Insects, Weather, Allergies & Smartphones



③ Take precautions against insects and ticks

Forests contain not only beneficial compounds but also physical risks, including:

  • Ticks (risk of SFTS, other infections)
  • Mites (e.g., tsutsugamushi disease)
  • Hornets, horseflies
  • Mosquito-borne infections


Preventive measures:

  • Wear long sleeves and pants
  • Cover neck and ankles
  • Use insect repellent
  • Shower and check your body immediately after returning



🚨 Nature is not sterile—this is crucial to remember.



④ Respect seasonal and weather conditions

Forest conditions vary by season:

  • Summer: risk of dehydration and heatstroke
  • Rainy season: risk of hypothermia and slipping
  • Winter: low temperatures, icy surfaces, blood pressure fluctuations


Common minor accidents:

  • Mild dehydration
  • Dizziness
  • Bruises from falls
  • Overconfidence during solo walks


Simple precautions:

  • Bring water
  • Avoid remote areas if possible
  • Cancel if the weather is uncertain

Choosing not to go is also part of optimal forest therapy.



⑤ Allergic individuals need special care

If you have:

  • Severe pollen allergies
  • Asthma
  • Insect allergies
  • Sensitive skin


Pay attention to seasonal allergens:

  • Spring: cedar, cypress
  • Summer: ragweed
  • Autumn: grasses and weeds



Recommendations:

  • Go when pollen levels are lower
  • Use medications and masks
  • Limit time spent in the forest
  • Never overexert yourself

Adapting forest therapy to your body is key.


⑥ Using a smartphone drastically reduces effectiveness

The benefits of forest therapy rely on sensory input—sight, sound, smell, touch, and breathing.

Looking at a smartphone while walking:


  • Keeps the brain in an urban mode
  • Prevents autonomic nervous system regulation
  • Reduces cortisol-lowering effects

Simply setting aside screen-free time greatly enhances benefits.
