why does sea food makes you thirsty?

seafood is salty... salt dehydrates you, therefore you get thirsty

You are either drinking water  with more calcium at some times or it's in the food you are eating.  In places there is more calcium in country deep wells than in city water wells which filter such things as lime deposits.

Just make sure the large amount you drink is not A COLD GLASS OF WATER. They are now saying that cold water causes what you've eaten to solidify! Warm water is now the way to go!

A full explanation of the physiology of thirst requires a longer answer than I can give here. For additional information, see the references below.\n\nWe do not completely know how the brain generates the sensation of thirst, but that is where it arises. In simplest terms, when the body needs water, sensors alert the brain, and some signals—one of which is a peptide called angiotensin II—cause the brain to produce the sensation of thirst and to tell the body to start taking in more water immediately. If just a tiny amount of angiotensin II is injected into the correct area of the brain, thirst and drinking result. In addition, saliva flow is inhibited in a thirsty person, making the mouth dry and amplifying the sensation of thirst.\n\nThirst is clearly related to the volumes of vascular space (in blood) and extravascular space (outside blood). When the body loses water, these spaces are less full. Sensors report that situation to the brain, and thirst results. This simple picture is made much more complex by the action of the kidneys, which either excrete or retain water, and a person's salt intake, which affects the concentration of salts in the vascular and extravascular spaces. If the body loses pure water and no change in salt content occurs, the concentration of salt rises, causing an imbalance in the body's biochemistry. Therefore, our physiological controls work to keep salt concentrations within normal limits. For example, the body retains or excretes water, or it responds to thirst by bringing in new water. The body also excretes regulated amounts of salt through the kidneys, in perspiration, in saliva, and in tears.\n\nWhen you exercise or work hard, you lose water through perspiration and transpiration (breathing). You may also lose some salt when you perspire. By the time most people feel thirst, they are already considerably dehydrated (too little water). The reason is that the vascular and extravascular spaces must actually shrink enough for the sensors to tell the brain to get more water. It is better to drink water before and during the exercise or work—before you feel thirsty—so that you do not become dehydrated. In addition, salt pills are almost never needed, even with heavy perspiration. If your salt level is low, your body will reduce the amount of salt contained in your sweat and you will not lose much.

Because you're body is still dehydrated.  The only fluid that truly hydrates the body is water.  All other beverages are digested through the digestive system as though they were a food - just learned this after being in the hospital with dehydration from seizures and stroke occuring at the same time - I now have to drink 120 ozs of water a day or my body feels sluggish and undernourished - if I drink another beverage - I have found it is usually unsatisfying as far as quinching thirst.  If your water is from your tap it may have a chemical in it you're reacting to - so I would suggest bottled water.

Because you r not dehydrated. u drink enought liquids.

The minerals and salts in the water dehydrates the body the more water you drink.

The amount of urine we make is dependent upon the amount of water and salts in our body.\nThe relative amount of salts and water in our body must be regulated and kept steady.\nOur kidneys adjust the amount of salt and water in our body.\nToo much salt or not enough water makes us feel thirsty and we drink.\nToo much water for the amount of salt inside us and our kidneys dump the water into urine.\nThe most variable process affecting the salt/water balance (apart from eating and drinking) is sweating. If we lose a lot of water as we sweat a lot during hot weather then there is less water put into urine. When it is cold we don't sweat much so the extra water is lost in urine.\n\nThe habit of eating salted crisps and peanuts developed from a marketing idea in pubs. Provide free crisp and peanuts on the bar and customers eat lots of salt. This makes us feel thirsty so we buy more drinks.

"bred2bbroken" covered the question well.  I add one interesting tidbit to his answer.  The sensors that tell your body that you are thirsty are in your head.  With all that blood and bodily fluids moving away from your feet and towards your head (due to the absence of gravity), you do not feel thirsty.  This causes a problem during reentry.  Suddenly, you are severely dehydrated.  This can lead to lapses in judgement, etc.  Astronauts, therefore, drink a gallon of water during their final orbit.  If reentry has to be delayed, due to adverse weather conditions or whatever, then they have to orbit again.  Guess where all that water goes?  :)  So, they make one pass around, which takes a little over an hour, and then they have to chug a gallon of water again!  :)

Maybe you are allergic to the ingredients in alcohol or it could be that your body is holding in water due to the alcohol.

if you eat a lot of salty food, then you are more likely to retain water. salt retains water. Water retention, medically known as edema, can be caused by a number of factors, from normal shifts in body fluid to excess dietary sodium and diseases such as heart or kidney disease.

Your skin felt the need for moisture.  The temperature of the water as well as the humidity of your surroundings will affect it also.  You could have had something to drink that dehydrated you a little.  You could of been thirsty and didn't know it.  Lots of reasons.\n\nJust be thankful that your body is created in such a way to handle this without you having to think about it.

Fish can often be seen gulping air from the surface during heat waves when oxygen in the water is depleted, other fish eat from the surface

I think fishes get thirsty if there is not enough oxygen in the water.

Because you are asking this question under the diabetic category, I'm going to assume that you are a diabetic.\n\nGenerally, if you are constantly thirsty, it is because your blood sugars are too high. When your kidneys recognize too much sugar in your blood, they begin dumping all the extra sugar into your bladder to get rid of it. However, water follows sugar and therefore, your kidneys also are dumping all the water you drink straight into your bladder. So when your blood sugar is high, it is very easy to become dehydrated. \n\nWhen you get your blood sugars down where they should be, your kidneys will stop filtering out the extra sugar and you won't be as thirsty.

water and lots of sugary stuff
