I'm getting this from memory of my high-school chemistry classes, so be careful.
Back then the explanation was that since the He nucleus has twice the positive charge as the Hydrogen one, it'd bring the electrons a bit closer. Both atoms have a single S orbital, He with two electrons.
Also, atomic Hydrogen won't remain atomic for long - it'll quickly connect to another Hydrogen so it's S orbitals share electrons.
Again, from memory of my high-school chemistry classes (30+ years ago).
