It is only a matter of degree, all green teas are relatively cooler in nature. Some cold. Those that are deeper baked are less so, those that are deeper roasted even less. Examples of deeper baked green tea: Huangshan Maofeng (traditional ones), Kaihua Longding etc; deeper roasted: Dinggu Dafang, Mengding Ganlu etc.
Less green tea when you are weaker in energy. More when you feel absolutely active.
Cheers
