As I guy who wakes up at 4:15 every day, I can tell you the alarm clock is no friend.
Who wouldn't rather sleep until they had enough ZZZZs and woke up naturally on their own? Truth be told, waking to an alarm seems to be an ineffective way to truly wake up.
found study participants who reported waking up to an alarm that went "beep beep beep" reported higher levels of grogginess than those who awoke to melodic alarms.
The theory is a beeping alarm might disrupt or confuse our brain activity as we wake up, and that a more melodic sound, or song, might actually help us wake up more effectively.
A couple of weeks back my wife reset my alarm to wake me with one of my favorite songs and it has been a pleasant change. The Aussies seem to have nailed it!
