Cause the B group erroneously included different vitamins. At the beginning of the 20th century, vitamins were called by their physiological action . The B vitamins had quite similar effects, and they were generally found in the same foods , so at first their names were all "vitamin B". Later it turned out that it was a whole group of substances with varying chemical natures and they weren't interchangeable. As they were isolated, they began to be given the indices B1, B2, B3, B5, B6, B9, and B12. Nowadays, though, only the designations B6 and B12 are usually found in the medical literature, the other B vitamins are commonly referred to by their chemical names: B1 for thiamine, B2 for riboflavin, etc.

   Pain Cluster headache, aka "suicidal headache," is so severe that many scientists believe it's the worst pain a person can experience.     Cluster headaches affect men at a greater rate than women. It occurs in series every few weeks or months. Each attack lasts from 15 minutes to 3 hours. Mostly the pain is concentrated around the eyes or behind the eye.    The exact etiology of the disease is uncertain. Pathological activity of the hypothalamus is considered to play a leading role in the development of the disease, as indirectly confirmed by the rhythmic nature of the headache episodes. Triggering factors responsible for triggering new attacks are individual for each patient.

   Batteries Each battery contaminates about 20 square meters of land or 400 liters of water with heavy metals. That's more than the average swimming pool is 25 meters long.    As it turns out, the reason is that batteries contain various heavy metals that, even in small amounts, can be harmful to human health.     These include zinc, manganese, cadmium, nickel, mercury, etc. After throwing away batteries corrode (their metal coating is destroyed) and the heavy metals get into the soil and groundwater. From groundwater, these metals can enter rivers and lakes used for drinking water.

  Energy Drinks Energy drinks contain plenty of sugar (more than 9-10 cc per 200 ml) - otherwise, the caffeine will reek of bitterness. Sugar, in turn, leads to tooth decay, obesity, diabetes and numerous other diseases.     Consumption of energy drinks greatly increases systolic blood pressure and causes heart rhythm abnormalities - while drinking pure caffeine has no such effects.    In the long run, such consumption affects almost all systems of the body and is highly detrimental to health, up to and including pathologies.
