Dos and don’ts of consuming lemon water

To ensure that lemon benefits your health, it’s not enough to simply drink hot lemon water. Take a look at the basic dos and don’ts to keep in mind.

Drink lemon water in the morning

The benefits of lemon water in the morning are many. Not only does the drink boost your immunity, it also jump starts your digestive system and prevents constipation. It freshens your breath naturally too. It is believed that drinking hot lemon water on an empty stomach allows your body to absorb the nutrients present in lemons better.

Drink lemon water all through the day

While drinking lemon water in the morning gives you a boost, don’t think that you can’t sip on this beverage all day. It’s an easy way to stay hydrated while giving your body the nutrients it needs.

Don’t consume lemon water in excess

Since the benefits of hot lemon water are plenty, you may be tempted to replace water with lemon water. However, the citric acid present in lemons can erode tooth enamel. So, ensure that your total consumption of lemon juice is no more than 4 tablespoons a day.

Don’t consume lemon water if you have sores

If you have sores, ulcers or boils in your mouth, refrain from drinking lemon water until they are completely healed. This is because the lemon juice can cause irritation.

Other Uses Of Lemon

Strengthen immunity

Lemon is known for boosting immunity because it is rich in vitamin C and antioxidants. In addition, it helps to strengthen the immune system's defensive capabilities against the flu and common cold viruses. Colds and coughs can be treated with a spoonful of honey and a glass of hot water with lemon juice. 

Assist with weight control

A glass of lukewarm water with a tablespoon of honey and a squeezed lemon can work to lose weight. Pectin is a substance found in lemons. It is a natural fibre that expands after consumption, causing you to feel fuller, faster and longer. In addition, it will stop you from snacking on bad foods that make you gain weight. Lemons should get consumed whole because the pulp contains pectin. Lemon's antioxidant content also aids in weight management.

Oral healthcare

We are all aware of how crucial vitamin C is for teeth and gum strength. Lemon is helpful for the mouth because it is a rich source of vitamin C. Scurvy is an oral disease that can be effectively treated with lemon. Scurvy is a condition that is caused by a lack of vitamin C and causes symptoms like swollen gums and bleeding gums. Lemon juice may ease the pain when applied locally to toothache-affected areas. It also helps in reducing swelling. 

Effective against throat infections

Lemon cough drops get advised for patients who have throat infections. It is because lemons naturally possess antibacterial properties, which will lessen the effects of bacteria and provide relief.

Lemons are Good for Hair

Lemons contain a lot of vitamin C, which increases collagen and promotes hair growth by igniting hair follicles. You can apply a mixture of two tablespoons of lemon juice and aloe vera gel to your scalp 30 minutes before taking a bath and then wash it off with a mild hair cleanser.

Drinking lemon water is definitely a great way to enhance your body’s immunity, but do you know of the other ways in which lemon juice benefits your health? Keep reading to find out.

Prevents kidney stones

Studies suggest that the citric acid present in lemons may prevent the formation of kidney stones. The reason for this is that citric acid increases the volume of urine, as well as the urine’s pH. Both these changes create an unfavourable environment for stone formation.

Improves digestion

Lemons are rich in pectin, a soluble fibre that improves gut health and aids in digestion. Moreover, it slows down the rate at which sugars and starches are digested by your body, which results in lower blood sugar levels too. However, to get the benefits of pectin, consume lemon flesh and not just the juice, as it is the flesh that contains the fibre.

Lowers risk of stroke

Studies indicate that the flavonoids in citrus fruits such as lemons bring down the risk of ischemic strokes in women. This is one of the most common types of stroke and occurs when a blood clot disrupts blood supply to the brain.

Reduces risk of cancer

Two plant compounds present in lemons, hesperidin and d-limonene, are valuable for your body. Studies have shown that they reduce the risk of several types of cancer, including breast cancer. Moreover, other studies have found that those who eat citrus fruits such as lemons regularly, are at lower risk of contracting cancer. However, more human studies need to be conducted to determine lemon’s efficacy in preventing cancer.

Improves skin quality

Collagen is responsible for keep your skin plump and maintaining its elasticity. When collagen is lacking, your skin sags and you will notice fine lines too. Your body needs adequate amounts of vitamin C to maintain collagen levels, which lemons provide in good quantities.

Potential Risks Of Lemon Juice

Allergies to Citrus

You may be allergic to lemons if you are allergic to grass pollen or citrus fruits such as oranges, grapefruit, or limes. Swelling, itching, or burning in the mouth and throat are common reactions. Some people may experience gastrointestinal uneasiness or headaches.

Lemon Juice Has the Potential to Damage Dental Enamel

There have been reports of dental erosion in people who consume large amounts of lemon juice. If you drink too much lemon juice, the natural acids in the lemon can erode dental enamel.

Migraines and Lemon Juice

Tyramine levels are high in lemon juice. Drinking lemon juice can cause migraine headaches if you are sensitive to tyramine
