Taking a hot bath or shower can help in three ways. A little self-care can remind you that you're fasting as another way to take care of yourself, and will solidify your reason to do it. If you find that fasting makes you cold (this is common), a hot bath will warm you right up. It can also distract you and help you get past a wave of hunger. Sip on some herbal tea or sparkling water, prop up your iPad and watch a little Netflix, or listen to some music or an audiobook.
