Giving player extra hearts

Is there a way that I can give a player extra hearts? For example, if you've ever played mineplex hunger games, you know that you get 8 extra hearts to start out with. Is there anyway I can acheive this in vanilla minecraft? I want to make a map so that players permanently have extra hearts.

Yes, the /effect command works, but don't go too hardcore on the health or it will spam your screen.

But to clear it when you do, use /effect @a clear.

I had solved my own question, just use this command:

/effect <player> 21 <duration> <amplifier>

use this as a template /effect 21 1000000 10
