Who faced with illness as a hangover know what it is.
Impossible agony, headache, nausea, cramps.
This happens from falling blood alcohol concentration.
Doing something pointless remain patient and wait.
Hangover causes you to urinate frequently (ie dehydrate), blocking the release of vasopressin
Vasopressin, also known as antidiuretic hormone, is produced in the posterior pituitary - it allows the kidneys to absorb water.
Without vasopressin fluid enters directly into the bladder.
Hangover causes headache and nausea
When you are too often run to the toilet, the body loses sodium and potassium, and you get what you get.
Hangover does not allow you to sleep
With increasing concentration of alcohol in the blood of your body becomes agitated, so you suddenly wake up and can not sleep deeply.
It becomes difficult to concentrate and remember
This is due to the fact that the withdrawal of alcohol produces an inflammatory response of the immune system.
Hangover causes stress
The interaction between the brain, the pituitary and adrenal glands (the hypothalamic-pituitary-adrenal axis) helps regulate the body's response to stress. Adrenal hormones cortisol plays a key role in reducing stress as it affects many body systems.
However, if too much cortisol, the body's ability to cope with stress is reduced.
