When you are thirsty, does your first reaction be to drink water? But in fact, drinking milk is more thirst quenching. A study in the UK shows that assuming a hydration index of 1 for water, a human control test found that milk has a hydration index of 1.5, which is more efficient than water. This is because after drinking a large amount of water, the kidneys will receive instructions to "produce more urine and expel excess water", which will quickly drain the water and greatly reduce the thirst quenching effect. If a drink contains nutrients such as sugar, protein, and fat, or electrolytes such as sodium and potassium, such as milk and orange juice, the emptying rate of the stomach will slow down, and the kidneys will receive instructions to produce urine, which can help us slow down urination and keep water in the body for a longer time, playing a more thirst quenching role. Of course, it is not encouraged to replace water with milk or orange juice. I hope everyone can develop good drinking habits, take small sips of water frequently, and don't wait until you are thirsty before pouring too much. Which is more likely to cause insomnia, milk tea or coffee? Many people can sleep with tea and coffee, but after drinking a cup of milk tea in the afternoon, they lose sleep. What's the matter? Originally, milk tea is not simply a combination of milk and tea. A survey shows that milk tea on the market generally contains caffeine, and even a cup of milk tea has 2-3 times more caffeine than a cup of American coffee, which is more likely to cause insomnia. Moreover, excessive caffeine intake or personal sensitivity to caffeine can also cause excitement, restlessness, insomnia, and even tachycardia and arrhythmia. The current widely accepted range of caffeine intake in the medical community is that healthy adults should not exceed 210-400mg per day (approximately 1-2 cups of 355ml American coffee). But everyone's physique is different, it is recommended not to drink too much and adjust according to personal circumstances. Why do you become a "little yellow person" after eating too many oranges? Oranges contain a large amount of orange β Carotenoids, if consumed too much at once, can enter the bloodstream in large quantities and cause the skin to turn yellow. This symptom is called "carotenemia". However, it has little impact on health as long as it is reduced in high levels β Foods containing carotenoids, such as oranges, pumpkins, carrots, etc., will gradually fade the yellow color on the skin.
