I'm in a fight with water

Yesterday I bought two bottles of water called Metro-Mint, in spearmint water flavor. The only ingredients are:
Purified Water
Mint

I drank one bottle last night, and immediately started sweating. It was hot outside, and I was being fairly active around the apartment so I thought, "it can't be the water."

I just finished drinking the second bottle a half hour ago, and I literally have sweat dripping down my face, and all down my body. What's up? Since when does mint make me a sweaty mess? The funny thing, is this water claims to do the opposite!
"Take one sip and experience the Chill Factor: The cooling sensation you can only get with Metromint. The real mint naturally stimulates the nerves, instantly opening your senses to send a fresh, cool feeling throughout your body."
I feel exactly the opposite of that claim. I feel like I'm going to pass out. I'm going to go drink some tap water.
