How long caffeine stays in your body
Caffeine has a half life of about 5 to 6 hours for many healthy adults, with a range of about 3 to 7 hours or more. A cup of tea has less caffeine than a cup of coffee, and strong, long brewed or milk tea can still contain a fair amount. Use the caffeine half life calculator to estimate what is left at bedtime.

Frequently asked questions
How long does caffeine from chai last?
The half life is about 5 to 6 hours, so some caffeine can remain for 10 hours or more.
Does tea have less caffeine than coffee?
Usually yes per cup, but strong brewed tea still has a fair amount.

Drink water, dim the lights and try slow breathing. Avoid more caffeine.
Is decaf tea fine at night?
Decaf has only a small amount of caffeine, so it is fine for most people.
What time should I stop drinking tea?
Many people sleep better stopping 8 to 10 hours before bed.
Is 8 hours too much sleep?
Eight hours sits inside the normal range. If you regularly need 10 or more hours and still feel unrefreshed, mention it to a doctor, because it can be linked with health conditions, medicines or poor quality sleep.
How do I move my bedtime earlier?
Shift it by 15 to 30 minutes every two or three days while keeping the wake time fixed, get bright light after waking and dim lights for an hour before bed.
Will waking at the end of a cycle remove morning grogginess?
It can help some people, because waking from light sleep is usually easier than waking from deep sleep. The effect is not guaranteed. Grogginess, known as sleep inertia, usually fades within 15 to 30 minutes and also depends on how much sleep you had and when you wake in your body clock.
