Asthma (AZ-ma) is a chronic (long-term) lung disease that inflames and narrows the airways. Asthma causes recurring periods of wheezing (a whistling sound when you breathe), chest tightness, shortness of breath, and coughing. The coughing often occurs at night or early in the morning. Asthma affects people of all ages, but it most often starts during childhood.
Restart or Reset Your iPhone. If your iPhone suddenly freezes or refuses to wake from sleep, you can sometimes resolve the issue by restarting it. Press and hold the âSleep/Wakeâ button until the âslide to power offâ message appears. Slide the arrow to power off your phone.
Sometimes you will see a temperature warning on an iPhone. The screen will turn black and a yellow warning triangle will appear. Alongside the warning is a message: âiPhone needs to cool down before you can use itâ. Leave your iPhone alone in a cool place until the temperature sensor decides that the iPhone is safe to work again. The iPhone will start of its own accord.
