7. Drink some green tea to help boost your immune system
Green tea has been lauded as a super food for its metabolic powers, its many antioxidants, and its place as a healthier alternative to coffee. However, green tea can also have great effects on your immune system. For the maximum effect of green tea with minimum bitterness, add a little lemon and honey after steeping for 2 minutes. Make sure not to add milk as that can counteract the goodness of green tea.
