When we are tired, your blood sugar levels rise and then decline, so we need something to cheer up. Then usually we reach for a cup of hot coffee. The body under stress releases adrenaline, which helps the body to fight stress. The other hormone of the adrenal glands, cortisol has a longer action than adrenaline and is secreted when a person is under stress for longer period. Cortisol increases blood pressure, and destroys the nervous system.
Various drinks that contain caffeine, such as coffee, cola and tea stimulate the production of adrenaline, which is normal for the body only in extreme situations, and thus drastically increases the level of blood sugar.
Yet many people consume coffee and tea several times a day and if they do that to stop the hunger, their adrenal gland secretes adrenaline. As stated, if the body is under stress for a long time, adrenal glands begin to secrete cortisol, which destroys the nervous system.
Thus, caffeine and other stimulants affect the body. However, if someone has low blood sugar, the consumption of coffee, cakes and various sweets will act on the body as a remedy.
Our body is getting tired of daily activities as stresses – stimulants and of food that is not adequate and balanced and starts to react and develops various illnesses and creates fat.
