Sleep, digestion, etc.: preconceived ideas about tea finally verified

You are quietly settled in your bed, ready to devour the last 50 pages of your novel. All that is missing is a good Christmas tea to be in “cocooning” mode. But that cup of tea will keep you up at night, right? Digestion, hydration, sleep, caffeine, and iron anemia: François-Xavier Delmas, the founder of the Palais des Thés, takes stock with us of these preconceived ideas about tea.

Tea prevents sleep: true and false

“Tea is a stimulant, not an exciting one. There is less risk that it will prevent you from sleeping. But there can be a psychological effect: if we tell ourselves that this cup will prevent us from sleeping, then it could prevent us from sleeping.”

If like us, you do not really see the difference between “stimulating” and “exciting”, François-Xavier Delmas enlightens us.

“The caffeine present in tea diffuses slowly and for a long time (about 10 hours) into the bloodstream to keep the mind awake. While coffee will have an immediate and intense effect, but in the less long term, only 2 to 3 hours.”

If really, you want to be sure to sleep with closed fists, the tea specialist gives you his tips to remove caffeine from your cup. “Brew your tea for 15 seconds for the first time, discard the water, and brew again. The caffeine will diffuse very quickly in the first water while the aromas will diffuse throughout the second infusion.”

Another possibility: brew your tea in water at 70°C, no more. The heat will not be high enough for caffeine to be released, but warm enough for the flavors to diffuse. Good to know, right?

The more the tea brews, the stronger it will be: false

In bitterness, yes. In caffeine, on the other hand, it is quite the opposite.

The more you let the tea brew, the more you will have a feeling of astringency, a harsh side … and less caffeine,” explains the founder of the Palais des Thés. So next time, a piece of advice: don’t forget your tea ball in the cup for 20 minutes.

Don’t drink tea with meals: true

If you are iron deficient, we may have found the culprit: your cup of tea.

“Tea contains tannins. These molecules interfere with the assimilation of iron ingested during meals.”

The tannins of a cup of tea would inhibit the absorption of iron from plants to the tune of 60%. Folic acid would also be impacted by our sips of tea; this is why pregnant women are advised not to drink tea around meals. Since prevention is better than cure, be sure to leave 30 minutes between the meal and tea time(before and after)to make sure you do not interfere with the absorption of iron by the body.

Tea helps digest: true

Tea helps digest: true

“That’s what they say, yes. This would be especially true for dark teas.”

But dark or not, a cup of hot tea 1 hour after a hearty meal, is always good to take according to Mr. Delmas. And for good reason: tea is rich in antioxidants that participate in the proper functioning of transit. If we can encourage our intestinal flora to work while feasting on a good tea, we do not say no.

Fasting tea is not recommended because it gives nausea. False

Maybe yes, maybe not. In fact, if you feel nauseous drinking your tea when you wake up, it would be more due to the way you prepare it than to the tea itself. Slim, we who thought it was enough to dip our tea ball in hot water and wait, it’s missed.

“If you leave the tea in boiling water for a thousand years, you can have a feeling of harshness and astringency that appears. Maybe it’s this taste that’s causing you this nausea.”

From now on, the hardest thing will be to be awake enough to properly prepare our tea as soon as we wake up when it is precisely this tea that is supposed to wake us up…

Hot tea quenches thirst more when it’s hot: False

In fact, it’s not as simple as that. If you drink too hot, the body will sweat to regulate its internal temperature, but at the risk of being dehydrated faster by losing a lot of water. If you drink too cold, the opposite happens. Your body will think – wrongly – that it is cooler and that it no longer needs to cool down.

The ideal would be to drink your tea neither too cold nor too hot, around 13 ° C. But hey, we can imagine that you don’t always have a thermometer on hand. So, tell yourself that in periods of high heat, a tea that is about warm is good.
