## Results of the 'Summer 2026 Home Heat and Humidity Awareness Survey'
Ichijo Komuten Co., Ltd. has conducted the 'Summer 2026 Home Heat and Humidity Awareness Survey' among 2,873 men and women. With predictions that this summer will be hotter than average nationwide, the survey investigated where people feel heat at home and their concerns regarding humidity.
### Survey on Heat
- **The areas felt to be the hottest at home are: 1st, 'bedroom' (24.5%); 2nd, 'living/dining room' (17.3%); 3rd, 'restroom' (15.7%).**
- **Regarding air conditioning usage last year, 'June' was the most common month to start usage (approx. 40%), and '4 months' was the most common duration (approx. 30%).**
- **During the record-breaking heat of last summer, approx. 40% of people answered they 'lowered the AC setting temperature compared to usual years.'**
- **The most common threshold for turning off the AC when going out is '1 hour or more (less than 2 hours)' (approx. 24%). Approx. 10% said they 'do not turn off the AC during the summer.'**
- **54.6% of people correctly understand either or both the 'Heatstroke Alert' and the 'Special Heatstroke Alert' (97.4% if including those who only know the names).**
- **The number of people who refrained from going out due to these alerts versus those who did not was roughly equal.**
- **Over 74% of people feel frustrated by the heat at home when returning from going out.**
- **Experiences of heatstroke at home for oneself, family, or pets rose from 14.8% in 2025 to 22.0% in 2026.**
- **77.3% feel they 'cannot sleep well due to bedroom heat in summer.' Measures: 1st, 'using AC'; 2nd, 'using fans/circulators'; 3rd, 'using cooling bedding.'**
- **Approx. 60% leave the AC on until morning while sleeping. Concerns: 1st, 'electricity bills'; 2nd, 'dryness'; 3rd, 'feeling too cold.'**
### Survey on Humidity
- **Over 70% are concerned about humidity in the home during summer. Problematic areas: 1st, 'bedroom'; 2nd, 'bathroom'; 3rd, 'changing room.'**
- **The biggest humidity issue is 'mold/mite growth.' Approx. 40% have discarded clothes or bedding due to humidity.**
- **Measures: 1st, 'AC dehumidification'; 2nd, 'ventilation by opening windows'; 3rd, 'using dehumidifiers.'**
- **Desired equipment: 'Air conditioning with little temperature difference throughout the house.'**
