The 3 Basic Types of Sleepers And What They Need From Their Alarm Clock

Best 12-Hour Alarm Clocks
Best 12-Hour Alarm Clocks. Image source:

There are three basic types of sleepers: light, deep and mixed.

Light sleepers need a gentle alarm clock to wake them up. They should avoid alarm clocks that have loud beeping sounds or those that have a bright display. They should also set the alarm clock to a lower volume and make it less sensitive so they don't get woken up by noises in the house.

Deep sleepers need an alarm clock with a very loud sound, something that will wake them up even if they're in the deepest stages of sleep. If they are not woken up by their alarm clock, they may miss important appointments or meetings.

Mixed sleepers can use any type of alarm clock as long as it is not too loud for them to hear comfortably.
