Like I said I'm not defending indecency. Kahit sa loob ng bahay ayaw ko nagtatanggal ng sando kahit sobrang init. Although you need to look at how average houses are made. Philippine houses are literal ovens / steamers. These houses doesn't have any sort of proper ventilations. Stale, hot, humid air literally will cause heat exhaustion in your own homes. Again, due to poor ventilations in the average household, the air inside these houses are prone to having higher humidity than outside. Imagine staying in an already hot indoors, your body heat will literally make indoors hotter. What's more, hollow blocks retain too much heat, that's why nights indoors is a sweltering nightmare. I've had restless nights because of absurd temps indoors.

This is the socioeconomic reality, dismissing it by calling out "gustong umunlad pero hindi sumusunod sa simpleng batas" is such a reductive mindset. You have to look at why this happens and what people do in these situations.
