After you clear cache and cookies:

Some settings on sites get deleted. For example, if you were signed in, you’ll need to sign in again. Some sites can seem slower because content, like images, needs to load again.

Cookies are files created by sites you visit. They make your online experience easier by saving browsing data. The cache remembers parts of pages, like images, to help them open faster during your next visit.
