That one should drink much (more) at tropical-hot temperatures, we have already heard enough. The especially warm tea and room-warm mineral water are suitable, is not exactly a culinary highlight. Nevertheless: From the heat experts of the desert, we can look a little bit, because cooling does not necessarily cool us the best. On the contrary, it stimulates the body to produce heat.
Drink in time
When Germany moans under tropical heat, doctors need to treat many people with circulatory problems. At temperatures above the 30-degree limit, the organism must reduce body temperature by copiously sweating over evaporative coldness.
Those who do not drink in time and refill the "sweaty" minerals such as sodium, potassium, magnesium or zinc, get circulatory problems. And this affects mainly women whose blood pressure is lower on average.
Ice-cold enjoy - not better in the summer
Ice cold drinks, however, do not help, as they reactively lead to heat production of the body, which in turn leads to additional heavy sweating. In addition, ice-cold drinks can put a heavy strain on the stomach. Unsuitable to take the necessary amount of 2.5 liters and more, are also alcoholic drinks, caffeinated tea and coffee and energy drinks.
Coffee and black tea are not thirst quenchers, but stimulants. They increase the pulse rate and act through the caffeine additionally sweat-inducing. Alcohol also affects the circulation and metabolism. Sugary drinks such as cola or sodas are no thirst quencher, but looseners. In addition, the calorie content of 400 to 600 kilocalories per liter is not exactly the crunchy beach body.
Like the Bedouins
From the desert peoples, we can learn that hot drinks such as fruit tea, which also contains important minerals, continuously stimulate cooling sweat production. In contrast, ice cold drinks provide additional heat production in the body, while hot drinks cause us to sweat too much. If you like it sweet, you should go for the line on calorie-free sweetener. Even room warm mineral water is well suited if it contains at least 200 milligrams of sodium and 50 milligrams of magnesium. Drinking water, on the other hand, is relatively low in minerals.
In order to compensate for the sweat-related salt loss, it may make sense to add a pinch of salt to the tea or vegetables and salad once or twice a day. Anyone who uses fluoridated iodine salt with folic acid also makes the thyroid, bones, teeth and blood vessels a pleasure at the same time. Especially with long car rides caution is now indicated.
It is necessary to take a break every one or two hours and drink at least a quarter liter of fruit tea with a pinch of salt or mineral water. Otherwise it can lead to dehydration or even thrombosis in the worst case.
