Hong Kong logs highest temperature of year so far, poll finds low-income residents swelter
- Survey of residents of subdivided flats or cage homes reports emotional instability, insomnia, dizziness and struggles with utility bills

Survey results from the non-profit Society for Community Organisation (SoCO) released on Sunday showed that 90 per cent of those who lived in subdivided flat and cage homes were experiencing health issues caused by the recent extreme heat, including emotional instability, insomnia, dizziness and skin problems.
SoCO deputy director Sze Lai-shan explained that “subdivided flats, cage homes and rooftop structures act like ‘ovens’ during the hot summer”, as materials with high thermal conductivity such as iron sheets and aluminium plates were common in such homes, which also lacked ventilation.
She added indoor temperatures could hit 41 degrees Celsius, higher than outdoor temperatures, in such places.

Cage homes are tiny boxlike quarters stacked from floor to ceiling and partitioned by thin wooden boards or mesh wire.
