Someone begins to bear malice on an empty stomach. To some extent this can be justified.
The simplest explanation - it is a drop in blood glucose levels. Low sugar activates the so-called contrainsular hormones: cortisol and adrenaline. If insulin drives glucose from the blood into the cells, then cortisol adrenaline on the contrary increase its level in the blood.
Cortisol is a stress hormone called. For some people it causes aggression. Crank reaction starts "fight or flight". Both hormones can lift people out of balance. In addition, in itself a low level of glucose in the blood is bad for the brain. Some internal restraining mechanisms may fail and the person wakes up hungry beast.
A bad temper is still in people. Then they at any level of blood sugar vrednichaet and trash around mood.
And there are all sorts of intermediate variants on the principle of "where the thin, there and tear." That is when the weak brains, even a moderate hunger upsets.
And there are problems with the adrenal glands, liver, or diabetes, when the body would be happy to allocate contrainsular hormones, but can not. Then simply drop in blood sugar, and the head is turned off.
In short, all people with similar problems better adhere to universal rules:
- Eat several times a day gradually.
- Avoid sugary snacks. They give sharp swings in blood glucose levels.
- Exercise regularly. Exercise helps to get used to changes in blood sugar and hormones. Developed muscles themselves help to cope with low blood glucose levels.
- Get enough sleep. This helps to keep the brain healthy.
- For the same reason, do not allow dehydration.
