9.Coffee
This one can be a blessing or a curse — the issue is the caffeine. A couple of cups of black coffee a day may boost your mood and energy, and up to four cups seems to be OK for most people. But more than that can make you jittery and anxious, and some people are more sensitive to it.
10.Tea
For some, the ritual of a cup of tea has a calming effect. Certain herbs — lavender and chamomile, for example — may help, too, along with the antioxidants in the tea leaves themselves. Just make sure you don’t get too much caffeine. Many teas have that, too.
