Many people think that overnight tea should not be drunk, and there are many opinions. One of the more "alarmist" claims is that drinking overnight tea will cause cancer. In fact, this statement has no scientific basis.

The reason why overnight tea is not suitable is that most of the vitamins have been lost after too long. But the overnight tea that has not gone bad has its own magical effects in medical treatment.

Anti-cancer and antioxidant

Tea water will turn reddish-brown if left for a long time. This is due to the oxidation of tea polyphenols into reddish-brown tea pigments. Research shows that tea polyphenols and tea pigments have strong anti-cancer and antioxidant effects.

Mighty eyes

The polyphenols in overnight tea have antibacterial and anti-inflammatory effects. If your eyes appear red, you can wash them with overnight tea several times a day.

Relieve itching

Use warm overnight tea to wash your hair or wipe your body. The fluorine in the tea can quickly relieve itching and prevent and treat eczema.

Grow hair

Washing your hair with overnight tea also has the effect of growing hair and eliminating dandruff. If you feel your eyebrows are sparse, you can use a brush dipped in overnight tea to brush your eyebrows every day. Over time, your eyebrows will naturally become thicker and brighter.

Strengthen teeth and clean teeth

After the fluoride in the tea and the enamel of the teeth are calcified, it will enhance the resistance to acidic substances and reduce the occurrence of tooth decay; fluoride can also eliminate dental plaque. It is best to rinse your mouth with tea two or three minutes after meals.

Remove bad breath

Tea contains essential oils and has a fragrant smell. Gargle a few sips of overnight tea before and after brushing your teeth in the morning or after meals to freshen your breath. Gargling with tea regularly can eliminate bad breath.

Sun protection

If your skin is sunburned, you can wipe it gently with a towel dipped in overnight tea. Because tannic acid has an astringent effect on the skin, the flavonoid compounds in tea also have anti-radiation effects.

Remove fishy and greasy

Overnight tea also has a strong effect of removing fishy odor and grease. Use it to wash your hands after eating shrimps and crabs to feel refreshed.
