Why a Cup of Chamomile Tea Belongs in Your Nightly Routine

This post breaks down the science behind chamomile tea's sleep-promoting properties, shows how to brew it for maximum benefit, and flags the few situations where nightly cups aren't a good idea. If you're looking for a simple, low-cost wind-down habit that doesn't require pills or complicated rituals, chamomile deserves a spot on your nightstand.

Does chamomile tea actually help you sleep?

Yes—though it's not a knockout sedative. Chamomile contains apigenin, a flavonoid that binds to benzodiazepine receptors in the brain and gently encourages drowsiness. A 2011 pilot study found that adults who drank chamomile extract daily fell asleep faster and woke less often than those taking a placebo. That said, the effect is mild. Think of it as a nudge toward relaxation rather than a switch that turns consciousness off.

The warmth of the tea itself helps too. Sipping a hot beverage triggers a slight drop in core body temperature once finished—and that cooldown signals the body that bedtime is near. (It's the same reason a warm bath before bed works.) For best results, drink the tea about 30 to 45 minutes before lying down.

What's the best way to brew chamomile tea?

For the highest apigenin content, steep loose German chamomile (Matricaria chamomilla) flowers in water just off the boil—around 200°F (93°C)—for 5 to 7 minutes. Tea bags are convenient, but whole flowers release more of the beneficial oils. Brands like Traditional Medicinals Organic Chamomile and Celestial Seasonings Sleepytime use quality sourcing and deliver consistent flavor if bags are preferred.

Here's the thing: brewing time matters more than brand. A weak 2-minute steep won't deliver much apigenin. On the flip side, brewing past 10 minutes pulls out bitter tannins that can upset a sensitive stomach. Here's how common preparations compare:

Are there any side effects of drinking chamomile tea nightly?

For most people, no. Chamomile is on the FDA's Generally Recognized as Safe (GRAS) list. The catch? Anyone with an allergy to ragweed, marigolds, or daisies should skip it—chamomile belongs to the same Asteraceae family and can trigger cross-reactions. Worth noting: chamomile has mild blood-thinning properties, so Mayo Clinic advises avoiding it before surgery or if taking warfarin.

Pregnant people should stick to culinary amounts (one cup) rather than medicinal doses until cleared by a healthcare provider. Children can usually tolerate a weak cup, but infants under 12 months should avoid it entirely. If you're looking for a caffeine-free nightcap that supports calm without morning grogginess, a simple cup of chamomile checks the box.
