Lemon water has enjoyed its share of the limelight, touted as a detoxifying drink that can boost metabolism, enhance digestion, and even brighten the skin. While its benefits are numerous, there are some lesser-discussed disadvantages that every enthusiast should be aware of. Here, we uncover five potential downsides to consuming lemon water regularly.

Lemon’s Unexpected Side Effect: Heightened Sun Sensitivity

Many are surprised to learn that drinking lemon water can increase the risk of sunburn (1). This is due to the presence of a compound called psoralen in lemons, which makes the skin more sensitive to sunlight. While the sun provides us with much-needed vitamin D, heightened sensitivity from lemon intake can cause the skin to burn more easily. If you are a regular lemon water drinker, it’s essential to amp up your sunscreen game or limit direct exposure to the sun, especially during peak hours.

Lemon Water-Canker Sore Connection

While canker sores are typically harmless and go away on their own, they can be incredibly bothersome. The citric acid present in lemon water can irritate these sores, exacerbating the pain and potentially prolonging the healing process (2). If you’re prone to developing canker sores or currently have one, consider giving the lemon water a miss until the sore heals. Alternatively, you can dilute your drink to reduce the lemon’s acidity.

Lemon Water Sparks a Migraine

Some people might be more sensitive to certain foods, including citrus fruits like lemons. There have been instances where these triggers exacerbate migraines (3). If you notice a pattern where consuming lemon water coincides with the onset of migraines, it might be worth discussing this with a healthcare professional or considering other refreshing alternatives.

Lemon Water’s Diuretic Effect

Lemon water has a diuretic effect, meaning it can increase urine production. Regular consumption can lead to frequent trips to the bathroom. While this might be seen as a benefit, as it can help in flushing out toxins, it can also become inconvenient, especially if you’re always on the move or lack easy access to restroom facilities. It’s also worth noting that excessive urination can deplete essential minerals and salts from the body, which are vital for several physiological processes.

Lemon Water’s Toll on Tooth Enamel and Dental Health

Lemons are undeniably acidic. Regular exposure of teeth to this acid from lemon water can erode the tooth enamel, leading to increased sensitivity and making them more prone to cavities (4). The protective layer of enamel is irreplaceable; once it’s gone, it’s gone for good. If you’re keen on continuing with your lemon water habit, consider drinking through a straw to minimize direct contact with the teeth. Also, wait about 30 minutes after consumption before brushing to prevent scrubbing the acid directly into the tooth surfaces.
