Can I give my 12 year old green tea for stress?

My 12 year old is stressed and I read that tea can help with stress. Is it safe to give him green tea at night?

Children are not recommended to have any caffeinated drinks. If stressed, try exercise, music, breathing method, mindfulness etc.

Sure it's safe. But the caffeine in tea might make it difficult for him to get to sleep.

Yes, it is safe to give. See if there are things that can be done to get rid of the stress such as tutoring, etc.
