Keep in mind your alarm is the very first conscious moment of your day, your brain releasing shit loads of cortisol isn’t the best way to set yourself up. Ideally you want to replicate nature if you can. Phillips have a wake up light alarm clock that fades on over time. If you couple this with some bird sounds or relaxing music that fades on after it’s light it’s very easy to wake up. And if you wake up in the cold set a timer on a heater to turn on before you wake up to begin to raise your body temperature.
