Fitness people can't drink black tea. Tea contains caffeine, which will aggravate dehydration. Therefore, it is not advisable to drink tea during exercise, but to drink water or sports drinks with low sugar and sodium. If you simply replenish water after sweating a lot, you can't replenish the lost electrolytes and minerals, but you can fully replenish them by drinking sports drinks. Drink as little as possible, or not. You can also eat some fruits after you replenish water.
