In average man, hormones are associated with two circumstances: with sperm toxemia in times of pimply youth and with the menstrual cycle of females. We also remember hormones (or, more precisely, about their lack) when we have to take Viagra otc or some other generic to cause an erection. (We are not talking about natural Viagra for women). Meanwhile, these biological substances control us throughout life, guiding and distributing, spurring and oppressing.
Stress hormones: cortisol and adrenaline
Whether you are running away from a neighboring dog or waiting for your turn to the dentist’s office – the hormonal response of your body is symmetrical: the hypothalamus begins to stimulate the release of hormones that cause a sense of fear – cortisol and adrenaline, playing the role of an alarm. They force your heart to beat more often, dilate the bronchi, saturate the brain with oxygen, mobilize the stores of fat and glucose to give you energy in an extreme situation.
Stably high level of cortisol in chronic stresses introduces an imbalance in metabolism, so your body begins to store heavily fat (only one-time short-term stress has fat-burning effect).
The perfect way to protect yourself from the stress hormones is physical exercise: three sessions in the gym will help curb the level of cortisol and prompt the disappearance of fat deposits in the abdomen, where the concentration of receptors for this hormone is the highest.
Hormones of appetite: leptin, ghrelin, cholecystokinin and insulin
Ghrelin begins the cycle – the “hormone of an empty stomach”. It stimulates the neurons of the hypothalamus, due to which we begin to feel hungry. After we began to eat, in response to the stretching of the walls of the stomach, cholecystokinin (suppressor of appetite) is released. From this moment, the work of hormones is aimed at making you get up faster from the table.
Insulin secreted by the pancreas and especially leptin, created by fat cells, signals us that it’s time to stop overeating. When you gain excess weight, the body begins to produce an increased amount of leptin, to which the brain reacts quite differently from the normal amount of this hormone: it thinks you are hungry, and makes you eat up to the heap. Scientists believe that insulin and glucose metabolism is responsible for the imbalance of leptin.
“Sexual” hormones: testosterone, LH, FSH
Why do you have such a hard and persistent erection? Not just because of natural Viagra for men. Testosterone is a key ingredient in the sexual health of a man. The volume of its secretion depends on the luteinizing hormone (LH). Well, for spermatogenesis, follicle-stimulating hormone (FSH) responds. With sexual arousal, your adrenal glands begin to intensively produce adrenaline and norepinephrine, leading to increased heart rate and increased blood flow in the muscles, brain and penis.
Energy hormone: thyroxine
Thyroxine is a hormone that converts calories into energy. As soon as the hypothalamus catches the first signs of fatigue, it sends an appropriate signal to the thyroid gland, which corresponds to the release into the blood of thyroxine, which is able to penetrate almost any body cells. The effect of this hormone is manifested by increased body temperature and increased heart rate. The majority of cases of disturbed thyroid production are genetically determined. Such conditions are suppressed medically.
Sleep hormone: melatonin
Immediately after sunset, the pituitary gland begins to create melatonin, a hormone helping to fall asleep and regulate circadian rhythms. Peak emission of melatonin is observed from two to four o’clock in the morning. Artificial lighting can quite significantly disrupt this process. Scientists believe that extra artificial light at night can contribute to the development of cancer, diabetes and obesity, as it violates circadian rhythms. Night awakening itself is not harmful, but it is important that in the bedroom it should be dark. So get tight curtains and turn off all the gadgets – just a small ray of light may reduce the concentration of melatonin in the blood.
