Also, consider lemons. Think how cooling and refreshing a little lemonade can be on a hot summer day. Lemon is also a refrigerant, so it helps to reduce body heat.
Thai-Go Lemon-Aid is the Anti-Heat Aid
A couple of years ago a friend of mine was having to work installing heating and air conditioning units. So, he was crawling around in attics in the middle of summer when the temperature is over 100°F. This means that the temperature in the attics could be over 120°F. It was exhausting.
So, I had him make lemonade with freshly squeezed lemon juice and maple syrup. But, we took it to the next level by adding Thai-Go to make Thai-Go Lemon-Aid. He put this in a thermos bottle and drank it while working in the heat. It made a huge difference and I've used it ever since for helping to cool down the body when it's hot.
It's easy to make Thai-Go Lemonade-Aid, just juice four lemons and then add an equal amount of maple syrup and an equal amount of Thai-Go the lemon juice. So, if you have 1/4 cup of lemon juice, add 1/4 cup of Thai-Go and 1/4 cup of real maple syrup. (You can adjust the tartness by adding more or less maple syrup.) You then add this mixture to water to taste.
If You Want to Stay Cool, Skip the Ice
Oh, and I highly recommend you don't add add ice or drink ice water. I learned from a friend a few years ago that ice water will actually make the heat feel worse! There was a group of about 6 or 7 of us working outside and everybody took a break and drank ice water except me and my friend. He said, "Watch, they'll all start getting cranky after drinking the ice water," and they all did.
