Getting up in the morning has gotten more difficult during the COVID-19 pandemic. The snooze button is harder to resist when you don’t have to make yourself presentable and rush to an office before 9AM. I think this is the reason for the sudden proliferation on Amazon of alarms that do more than just ring.
The pinnacle of this type of product is the Shock Clock. It is like a Fitbit or an Apple Watch in that you are supposed to wear it around your wrist as you sleep. However, instead of just vibrating, it can—as the name indicates—actually give you a small shock.
Although it does have a vibrating option (as well as the standard beep), the big feature is the zap. It is literally designed to jolt you awake with a small electric discharge. Still think you might sleep through it? You can also set it such that the only way for the shocks to stop is to get out of bed and do jumping jacks. You may not be too happy at about, especially when you are starting the new routine, but you will certainly be awake!
The price is a bit steep at $150, though in theory you could make that money back from being more productive. If you want something cheaper—or simply something that doesn’t send electricity into your body—then there is a nearly endless selection of a different type of morning alarms for heavy sleepers. This type of alarm goes under your bed, making the mattress move in the morning and therefore shaking you awake.
More or less identical (since they probably come from the same factory in China), these vibrating alarm clocks all run somewhere between 20 and 30 bucks:
