When I get a lack of sleep, I often have a splitting headache the next day. Other people never get any headaches. What's wrong with me?

When I get a lack of sleep (or especially multiple nights of bad sleep), I often have a splitting headache the next day that makes me unfunctional and worsens until I get more sleep. Other people I'm with have the exact same sleeping routines and never get any headaches, and can still function despite being tired. What's wrong with me?
