10 Simple Habits to Stay Cool and Save Energy During Israel's Heatwave

As Israel experiences a significant heatwave, air conditioners have become essential for comfort, yet many common habits can inadvertently increase indoor heat and electricity costs. Experts recommend several practical adjustments to daily routines that do not require expensive equipment but can greatly improve cooling efficiency and reduce energy consumption.

Key tips include closing shutters early in the morning before the sun heats the house, especially on east-facing windows, and opening windows only during cooler times such as early morning, evening, or night to avoid letting hot air in. Setting air conditioners to a moderate 25 degrees Celsius instead of extreme lows like 16 degrees can reduce electricity use, as each degree lower may increase consumption by about 5%. Regularly cleaning AC filters is also crucial to maintain airflow and cooling efficiency.

To minimize indoor heat generation, it is advised to shift cooking and use of heat-producing appliances like ovens and dishwashers to evening hours. Staying hydrated by keeping water bottles visible encourages regular drinking, while wearing light, breathable clothing and using light bedding can improve comfort. Cooling efforts should focus on occupied rooms by closing doors to unused spaces, and turning off unnecessary electronics and lights can further reduce heat buildup.

Adjusting daily schedules to avoid strenuous activities during peak heat hours and checking on vulnerable individuals are important safety measures. Recognizing symptoms of heat-related illnesses such as dizziness, confusion, or loss of consciousness is critical, and immediate medical help should be sought if heatstroke is suspected. These small but effective changes can help Israelis endure the heatwave more comfortably and economically.
