What causes humans to have different sleeping types rather than just all having the same type of sleep?
In: Biology
Aside from a few chemical balances, trauma can shape people into waking up towards certain triggers.
For some people, it’s the sound of the garbage truck in the morning. Others, garage doors. For me, it’s any physical/audio sensation that doesn’t feel like it’s from myself because of overlap.
It makes sharing a bed a very difficult if not impossible task if I need to actually sleep. Quieter, darker, secure, and familiar are the best bets on qualities for minimizing my tendencies where I can even wake myself up, and it’s pretty similar with other light sleepers i’ve encountered.
