Why is it bad to drink lemon water every day?

While it's not exactly bad to add lemon to your water each day, dental professionals caution against going into it blindly. That's because the citric acid in lemons could have a negative impact on your teeth. In 2015, a study published in the journal PLoS One found that the acid from lemons could actually erode the enamel that covers your teeth, weakening it over time and increasing the risk of cavities and other dental health issues over time.

Those with stomach sensitivity may want to beware as well. That's because Healthline says that too much lemon water can cause heartburn in those with sensitive stomachs, or even make heartburn symptoms worse for those who already experience the condition.

Of course, every person is different, and you should consult with your healthcare provider before making any drastic changes to your diet. Additionally, you'll want to talk to your dentist about the potential impacts the added citric acid could have on your tooth enamel, especially if you're already dealing with dental health issues.

How to make lemon water:

Ready to add the flavorful drink to your diet? Fortunately, making your own lemon water at home couldn't be easier. All you'll need is a glass, access to water, ice, and lemons.

First, rinse your lemons off to remove any dirt or bacteria from the rind. Next, lay your lemon on its side so that both of the pointy ends are horizontal with your cutting board.

Take a sharp knife and slice your lemon down the middle, and then make similar cuts along the lemon, slicing small circles off of the fruit as you go. Add a circle to your water, increasing the number of lemon pieces you add to your water until you've reached your desired flavoring.

Want more lemon juice? Skip the circles and cut your lemons into wedges instead. Before adding the fruit to your drink, squeeze the wedges over your glass by folding the ends in on themselves.

This will add a more concentrated amount of lemon juice to your water, helping to pack a more flavorful punch! Add the leftover rinds to the glass for even more flavor, or toss them into your compost bin when you're done.
