Netherlands heat‑wave tips: iPhone automation and sleep strategies

A Dutch guide shows how to use the iPhone Shortcuts app to automatically open windows when outdoor temperatures exceed indoor ones, helping homes stay cooler without air‑conditioning. The automation compares indoor and outdoor sensor data, calculates the temperature difference, and sends a notification to open or close the window.

Health experts also recommend eight practical measures for better sleep on hot nights: take a warm shower to trigger cooling, avoid alcohol, keep the bedroom cool with cotton or satin bedding, use fans with frozen bottles or ice packs, turn off electronic devices, keep windows closed until outdoor air is cooler, and eat light or spicy meals to reduce metabolic heat.

These combined tips aim to improve comfort and sleep quality during the upcoming period of high temperatures in the Netherlands.
