Does drinking Oolong Tea at Night Keep You Awake?

Oolong tea is gaining in popularity due to its health benefits and pleasant taste. But can it cause sleeplessness in those who drink it at night?

What Is Oolong Tea?

Oolong tea is a form of Chinese tea made from partially oxidized leaves of the Camellia Sinensis plant. It offers a unique flavor profile and its high levels of antioxidants are thought to provide many health benefits.

Does Oolong Tea Have Caffeine?

Oolong tea does contain caffeine, though levels tend to vary depending on the type of tea and how long it is steeped. Generally, the lighter the color of the tea the less caffeine it will contain.

Will Drinking Oolong Tea at Night Keep You Awake?

It is possible that drinking oolong tea at night can lead to sleeplessness. Caffeine is a stimulant and can affect your sleep patterns. While the amount of caffeine in oolong tea is lower than other types of tea, it is still present.

If you are sensitive to caffeine, it is best to avoid drinking oolong tea past mid-day or to choose a caffeine-free variety. If you don’t react to caffeine, you may be able to safely drink oolong tea up until just before bedtime, though this is likely to vary from person to person.

Benefits of Drinking Oolong Tea Before Bed

Oolong tea may also provide some benefits to those who drink it before bed, depending on the type. The antioxidants it contains may help boost your immune system and some varieties, particularly those labeled as “sleepy time”, are thought to have calming effects and help with relaxation.

Tips for Consuming Oolong Tea at Night

If you choose to drink oolong tea at night, here are a few tips to consider:

  • Choose caffeine-free varieties: If you are sensitive to caffeine, opt for a caffeine-free variety of oolong tea.
  • Adjust brewing instructions: To reduce caffeine levels, use less tea leaves or reduce steeping times.
  • Try sleepy time varieties: Look for teas labeled as “sleepy time” or “bedtime” which are made with herbs and spices that may help you relax and fall asleep more easily.
  • Keep track of your sleep: If you are unsure how your body responds to drinking oolong tea at night, monitor your sleep patterns and make adjustments if necessary.


Drinking oolong tea at night can keep you awake if you are sensitive to caffeine. However, oolong tea can also be enjoyed before bed for its antioxidants, calming effects and its unique flavor. If you choose to drink oolong tea at night, look for caffeine-free varieties or those labeled as “sleepy time”, adjust brewing instructions to reduce caffeine levels and keep track of your sleep.
