✔️ Why herbal tea is perfect at night

Several herbal infusions have calming, sedative, or digestive benefits.

🌙 Chamomile

A study published in Phytotherapy Research found that chamomile improves sleep quality and reduces insomnia symptoms.

🌙 Mint

Peppermint tea relaxes digestive muscles and reduces bloating, making it ideal after dinner.

🌙 Lavender

Lavender tea has proven anxiety-reducing effects according to a 2015 study on mood and relaxation.

✔️ Why not in the morning?

Herbal tea does not provide caffeine, meaning it won’t boost alertness, energy, or focus for most people.

🧊 4. Iced Tea: Never Daily — Only Occasionally

Iced tea is refreshing, but it must be consumed in moderation.

✔️ Why iced tea should not be consumed daily

Most iced teas—homemade or commercial—contain:

• Added sugar
• High amounts of oxalates, which can stress the kidneys
• Caffeine (if made from black tea)

In fact, a medical report from the University of Arkansas linked excessive iced tea consumption to kidney stones due to high oxalate levels.

✔️ When iced tea is OK

Enjoy it occasionally, especially unsweetened versions.

✔️ Health-safer alternatives

• Cold-brewed tea (much lower in tannins and acid)
• Infused water with lemon + mint
• Herbal iced teas
