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.
Apple recommends operating temperatures for the iPhone of 32 to 95 degrees Fahrenheit (0 to 35 degrees Celsius) -- and for non-operating temperatures, it recommends minus-4 to 113 degrees Fahrenheit (minus-20 to 45 degrees Celsius). Allow the device to slowly equalize to the environmentâs temperature. Press the âHomeâ button when the iPhone has cooled down to assess whether the temperature error is still present. Test the phone's functionality by attempting to utilize the device normally. If normal operation has been restored, internal damage has likely been avoided and you won't need to replace the iPhone.
