Rebooting the computer is the only way to clear the swap file, that osx uses for Virtual memory and clearing ram.
You can clear cache without rebooting, for instance in Safari, select from the Menu Safari, then empty cache.
Some programs (like Safari) have memory leaks, that is a bug in their programming that basically keeps requesting more memory from the system but does not give it all back. A reboot from time to time fixes this problem.
