After a long day you can’t wait to finish dinner and go to bed. But you can’t forget the water bottle to keep on the bedside table. You always have thirsty before bed? Here is the incredible reason.
Being thirsty in the evening
After a long day at work, at school or busy with a thousand commitments and daily errands, you can’t wait to go back to House to rest. After having prepared dinner and washed the dishes, thought about your hygiene or evening beauty routine, you have now come to approach your bedroom to enjoy the well-deserved rest you deserve. But this is not without first getting hold of a bottle of fresh water to take to your bedside table. Yes, because for some time you have always thirst in the evening before sleep and this even if you drank during dinner. There is nothing to do: whether it is a glass of water, a tea, a cup of milk or the classic glass of red wine, you must necessarily have a drink before going to bed.
Why does this happen? Is it the indicator of some problem? You always have thirsty before bed? Here is the incredible reason that leads you to always have to drink something before bedtime.
The reason
About having thirst before bed, recent studies have investigated this issue by raising responsibility for the biological clock. It is a sort of preventive response of circadian rhythms, which would stimulate the thirst neurons ahead of time to prevent what could be a probable dehydration problem that would occur during the night hours.
In practice, the amount of liquids taken before rest is unconditionally increased even though it is not needed. The biological mechanism then induces thirst before sleep and makes us drink before night to prevent dehydration during the hours when we are unconscious even if the body has already been sufficiently hydrated.
The biological clock
The studies conducted have hypothesized the responsibility of the suprachiasmatic nucleus, which is located in the hypothalamus and is composed of a group of neurons that are responsible for the correct regulation of circadian rhythms. This nucleus through vasopressin, a neurotransmitter whose job is to keep blood volume constant, is able to communicate with thirst neurons. When the nucleus is electrically stimulated, an increased release of vasopressin occurs, which activates the thirst neurons, thus prompting drink before bed.
The biological clock therefore has an incredible functioning within itself. In fact, it is able to predict when you will start to sleep and to force the brain to activate itself to transmit the thirst stimulus to the body to ensure that we stock up on fluids, thus avoiding dehydration at night.
