Drinking Hot Tea in the Desert Actually Cools You Down

I was twenty, sitting in a tea house in a far-flung desert town. It was summer, so the temperature hovered around 120 degrees (48 C) in the dusty bazaar. My friend suggested that we stop for some tea as he gave me a tour of the marketplace of his hometown, famous for its castle, its hard workers, and its heat. “Welcome to hell,” another local friend had quipped earlier as we drove into town, wiping the sweat off his brow.

Always one to prefer heat to cold, I had been eager to see if the summer weather in this town was as bad as everyone made it out to be. Rising early our first morning, shortly after sunrise, I had stepped out of the house and into the sunlight. Immediately, I was hit by a rush of blasting, hot wind, and oppressive radiant heat, as if the entire sky were a giant hair dryer aimed right at me. Mind you, it was only 6:30 am. I quickly stepped back into the protective shade of the cement house. If I had ever doubted before why so many desert cultures wore so much protective fabric, now I understood. At a certain level of heat, you do whatever you can to keep the sun’s rays off your skin, even if it means going around covered in many folds of cloth.

As we later made our way through the bazaar and then found our seats at the tea house, I was beginning to adjust somewhat to the constant feelings of living in an oven and clothing always soggy from sweat. I gratefully received a bottle of cold water alongside my scalding black chai. I chugged the water eagerly.

“Are you hot, my son?” asked a mustachioed older man, sitting across from me and smiling in his turban and flowy local robes.

“Yes, I’ve been told about the summer heat here, but now I see how true it is!” I responded, gulping.

“You know how we stay cool?” he asked me, raising his small steaming chai cup and saucer. “We drink this all day!” he said, laughing.

I looked at him, a little puzzled, wondering if he was joking or serious. He picked up on my expression and explained further.

“We drink the hot chai and it makes us sweat. And our sweat cools us down. That is how it works,” he said, seemingly satisfied that he had just handed down an important life lesson to this young foreigner.

I could tell he believed what he was telling me, but I wasn’t sure if I believed him or not. My love for local chai was intense, and so I was willing to drink it all year round, even in the fever heat of summer. But surely hot chai doesn’t actually cool you down in the desert. Maybe it was just a trick of the mind, a placebo of sorts that these desert men had learned to tell themselves in order to justify downing so many cups of sugary caffeinated goodness seasoned with cardamom and cinnamon. The logical thing to believe is that hot drinks raise your core body temperature and cold drinks cool it down. I left our interaction mostly sure that I was right and the locals mistaken. But a part of me has always wondered if there was something to what the old man was saying.

Then this week I came across an article in The Smithsonian that would make the old desert man crack a big smile, exposing all of the teeth he’s missing because of his chai habit. Turns out that a hot drink on a hot day really does cool you down. And this has now been scientifically verified with the help of a bunch of scientists and cyclists. Somehow, the cooling effect of the sweat produced by a hot drink on a hot dry day is actually greater than the warming effect the drink has on the body, making it a net win for a cooling effect. The article gets into the likely biological process for those interested.

So now I know. Hot drinks warm you up in the winter. They also cool you down in summer. How strange and wonderful. No wonder I like them so much.

There is one big caveat in all of this, however. In order for a hot drink to cool you down, you must be in an area of dry heat, not one of humidity. Since a humid environment prevents sweat from evaporating, the hot drink will actually raise your body temp, not decrease it. But as long as you are in some kind of desert or low-humidity setting (and able to sweat), the trick should work.

All of this reminded me of what a tricky thing it is to interact with local lore and tradition. By default, we want to dismiss local knowledge that seems bizarre to us as superstition or old wives tales. But quite often there is something to it after all. Not in every case, but often enough that we ought to reserve judgment on local claims until we’ve looked into them somewhat. As Tolkien wrote in The Lord of the Rings, “Pay heed to the tales of old wives. It may well be that they alone keep in memory what it was once needful for the wise to know.” Oral tradition should not be dismissed out of hand, simply because it initially strikes us as absurd.

A missionary friend in Cameroon shared with me this past week about a volcanic lake in that country. At some point in the 80s, large amounts of toxic gas were released from the lake, killing all who lived in the villages around its shores. However, all of those villages had been founded and populated by newcomers to the area. The long-time residents did not live close to the lake, since they had an oral tradition that it was spiritually deadly to dwell too close to the water. Apparently, this lake is prone to this kind of toxic gas release every 150 years or so, meaning that the indigenous villagers had an oral tradition that preserved a deadly historical event from the distant past, although it had become clothed in their animistic worldview.

I remember another story from my childhood in Melanesia, where a village pastor, eager to prove the local traditions wrong, had decided to cook and eat a bird locally believed to be poisonous and used in witchcraft. The pastor ate the bird – and almost died as a result. Turns out this black and orange bird is the only poisonous bird known in all of nature. Local oral tradition wins again.

Why do we so often assume that local tradition is untrustworthy and bogus? Because sometimes it really is, and it keeps locals in bondage to empty and dangerous lies. Consider the Middle Eastern and Central Asian belief in patrogenesis, the idea that offspring one hundred percent comes from the father, and the mother is merely a carrier, a vessel. All kinds of bad stuff have come from this cultural belief, including laws that disadvantage the mother when it comes to custody of her children – even if the man is abusive. Or, the cultural belief that the honor of the extended family is most dependent upon the sexual purity of the women in the household, resulting in honor killings that almost exclusively target erring female family members. In Melanesia, tribes until recently believed that if your enemy was strong in something, you could kill them and eat their corresponding body part for that ability, thereby getting stronger in that ability yourself. This local tradition led to widespread cannibalism and all of the dark effects associated with it.

However, what often happens is that Christians of the reformed camp approach culture with eyes only for these cultural lies. We often have a default posture of Christ-against-culture when it comes to local knowledge and traditions. We know that all cultures, like all people, are fallen and under the curse of sin. We know that this affects every aspect of a person, and every aspect of the culture – that total depravity is not just individual, but corporate as well. The mirror that once reflected the image of God so well has been shattered, and gross distortion has resulted. And yet a shattered mirror has not ceased reflecting entirely. No, if you lean in close and focus on small individual shards, a somewhat accurate, limited reflection can sometimes be found. The fact that the fall has damaged every aspect of a culture does not mean that the image of God is no longer present at all, shining out – sometimes dim, sometimes bright – through the distortion. Just as the restoration of the image of God in believers will not be perfected until the age to come, so the utter loss of that image in unbelievers and their cultures will not be complete until that same coming age.

This means that we cannot approach the culture of an unreached people group only prepared for the gospel to begin rejecting and discarding local beliefs and culture. We must be prepared for much of this, but not only this. We must also be ready to discover local beliefs and customs that fit quite well with a biblical worldview – that at times fit even better than those of our own culture. In these cases, the local cultural practice or belief is to be retained, but filled with a new motive, that of the glory of God and love for neighbor.

Few contemporary missionaries are at much risk of the kind of overt cultural pride present in the colonial era. In fact, we are more often at risk of the opposite, an unbiblical open denigration of our own cultures as we seek to embrace the local one. But pride is a slippery thing, and if our only setting is Christ-against-culture, then we will find ourselves prematurely scoffing at local wisdom that will eventually prove to be just that – wisdom. And scoffers don’t win trust. Those who sneer at local methods of chai drinking are less likely to find a hearing when it comes to the bigger questions of life and death and eternity.

Such is the challenge of engaging local lore and tradition. You may find lies straight from the pit of hell. Or, you may find truth that has been marvelously preserved, against all odds. We must learn to anticipate both and to humble ourselves when we get it wrong. We should listen carefully to the old men of the desert, ready both to learn and to stubbornly upend the traditions of ancestors when needed. We are tasked with this great untangling, with the laborious task of seeking to glue the shattered mirror back together. It will take a long time and countless conversations. And hopefully, lots of cups of chai. Even when it’s hot outside.
