The C-H and C-F bonds are polar and so the electron density will be shifted towards carbon in the C-H bonds and towards fluorine in the C-F bonds. Directing orbitals with more s character towards the hydrogens is stabilizing, while directing orbitals of less s character towards the fluorine is destabilizing but to a lesser extent.
