- I like coffee culture, the taste of cappuccino on coconut milk, and for me it’s a pleasure to sit in a coffee shop overlooking the sea in my favorite city. However, I do not like it when a glass of coffee becomes a companion of fatigue and stress. Several times a year I take "coffee breaks" of about a month in length. Usually this time coincides with prioritization and adjustment of habits. Now I haven’t been drinking coffee for about three weeks now and feel better than drinking it daily.
Thoughts do not jump one from another, it’s easier for me to concentrate, I get less tired by the end of the day. Refusal to drink coffee did not affect the quality of sleep. I sleep well with and without coffee. I know that in the case of coffee, the measure is important, so when I want to return the drink to my life again, I will limit the amount.
- Caffeine can indeed increase the
level of anxiety
- this is due to the fact that the caffeine molecule is so small that it reaches the brain in just 20 minutes, easily bypassing the blood-brain barrier. As soon as the molecule is in the brain, it blocks the absorption of adenosine, a neurotransmitter that signals the state of drowsiness to the brain. We feel alert or, in more serious cases, start to worry. Caffeine also stimulates the adrenal glands. But we are now talking, of course, about huge doses of coffee.

There is evidence that coffee stains tooth enamel, and the same drink with sugar can contribute to its destruction.
If you stop drinking coffee (we are talking about espresso or Americano, that is, about dark types of coffee without milk), your teeth will stop darkening.
But coffee without sugar can partly help maintain healthy teeth. So, Italian researchers have proven that coffee helps eliminate bacteria from the surface of the teeth. In similar studies in the United States, it was found that coffee contains chlorogenic and nicotinic acids, and it is they that prevent the appearance of microbes that contribute to the development of caries.
- Staining of tooth enamel with drinking coffee is due to microcracks present in it. If you care about dental health, observe the rules of hygiene, you should not be afraid of darkening. You don’t need to drink too hot coffee and add a lot of sugar to the drink. In all other respects, coffee and teeth are a healthy union.
