Picking the kind of features you want in the display depends upon your preferences. There are clocks with simple displays that focus only on the time. When such details are displayed, the screen tends to become jampacked. Additional features: Many alarm clocks display more information than just time, like temperature and calendar.However, if the first one appeals to you more, you can look for a clock with a customizable volume control feature. It is advisable to go for the second option. On the other hand, the ones with progressive sounds play the alarm tone with an ascending loudness, giving you time to wake up. Alarm clocks with loud noises can lead to waking up suddenly, which could be detrimental to your health in the long run as it can lead to high blood pressure. Sound: One of the primary features of an alarm clock is its sound.So, it is advisable to choose an alarm clock that allows you to balance both by offering adaptable display brightness. However, bright light may not let you sleep at night and dim light may not display the time in the morning. Thanks to this feature, you can set your clock to a high or low brightness depending on your need. To minimize that, some alarm clocks are equipped with different wake-up features, such as a customizable display option.
