it doesn't matter if it is in cold water. i'm on the swim team. and i usually get hungry after practice but i waste a lot of my energy swimming, so i gain it all back with food :) yeah, swimming is a good way to lose calories. i lost about 7 pounds since i've joined.

its called freezing point depression.\n\nwhen you add any electrolytes (like salt) to water, you lower the freezing point of water, the more you add, the lower the freezing point

I dont think thats something you could do by taking cold showers, body mass does make a difference when you are getting into the pool.. but I think the more you do it, the less it will matter to you being chilly\n\nYou'll get used to the feeling of chilliness.. but your body wont necesarilly adapt to it

no.  if you are feeling hungry it's probably because you aren't drinking enough water.  try drinking water and that will help you feel less hungry more often.

i will tell you the exact answer to this, see wat happens is when you drink more of water ur stomach is distended, the thirst centre in ur brain is satisfied, at the same time ur hunger centre is also inhibited so u tend to eat less.... also water helps in faster digestion and more excretion of waste products helping u to lose weight

Researchers now believe the culprit may be carbohydrates.  More specifically, certain types of carbohydrates, including rice and pasta.  These carbohydrates have a high glycemic index (GI), which means the body needs to produce extra insulin to digest them.  Excess insulin causes the blood sugar to plummet, creating a hungry feeling.

It is actually good that your body is craving water and warm water at that. Most people do not realize that by the time they are thristy they are already considered to be dehydrated. Most people also do not realize that cold water is actually not good for your digestive system.  It lowers the temperature which constricts the blood vessels in the stomach and upper intestines which slows the constriction action and therefore your digestion.  Another thing to note is that drinking sums of liquid including water while you are eating dilutes your digestive juices which also slows your digestion.  Another thing to note, while it is sad to think you may do more harm drinking your tap water than you do good.  Depending on the municipalities and the age of your home you could be ingesting all kinds of toxins.  There are a few places online you can get your water tested or often times culligan or another local purified water company will test your water for free in order to get you to realize that your water is contaminated. I am not sure where you live but you can also log onto the local EPA website and find out the alerts for your local water supply.  They are not required to publish them accept on their website and there is nothing that has to be done unless they are far over the levels and then they have so long to bring it into specs.  But those are what they deem to be appropriate, which you may or may not agree with.\n\n\nThe good news is that you are listening to your body and providing what it needs and deserves.  A great book to check out is Your Bodies Many Cries for Water. So rejoice top that and see if their is anything else it is trying to clue you in on.\nGood luck

Everyone's talked about eating and that's all true - increased likelihood of throwing up, cramps, etc. But you asked about drinking beer as well.\n\nIt's not a good idea to drink alcohol before swimming (especially in rivers, lakes, oceans, etc.) because:\n\n- alcohol increases blood circulation to the skin and extremities. Result: you get colder quicker (and water takes away body heat 20x faster than air at the same temperature does)\n- being cold slows down your thinking. If you're also muzzed with alcohol, that makes it much easier to get into a dangerous situation ('cos you're less likely to see it coming)\n- alcohol slows down your thinking, so a bad situation is more likely to get worse than better\n- you're significantly more likely to drown, or get someone else into trouble when they try and rescue your sorry butt\n- a very high percentage of drowning deaths are the direct result of drinking before going swimming.\n\nSo, don't do it!

When you feel like eating, drink a full glass of water and take a short walk. If you're still hungry when you get home, you're really hungry.

yeah, it's your body using it's energy to digest the food instead of keeping you at a steady temperature.  espeically happens after i eat a lot.

That often happens from too much salt and poor circulation. Just put pressure on where it's numb. It's nothing serious as to where you need to see a doctor. Just cut down on the salt and if you start noticing any patterns or constant craving for water then you should see a doctor. Poor circulation and constant craving for water are signs of becoming a diabetic. I've learned all this stuff. ♥

Your digestive system is at work all the time and normally during the day you're eating at more or less regular intervals so there's food in your stomach to be digested.\n\nAfter a nights sleep there's likely to be little left to digest so you get feelings of hunger.\n\nPartly it will depend on what you eat - a 'heavy' meal high in fats and proteins for example, will take longer to digest than a 'light' meal such as a salad.

There are specific neurons specialized for cold sensations- under hot water, there is ectopic activation of these neurons from the physical effects of heat on the synaptic membranes- These are then communicated through the spinal cord and mis-interpreted.

When you are cold, your blood goes to your body's core, away from the extremities.  Once you hit a warm shower, your body dumps blood back to your extremities when they're still cold.  This causes a drop in your body's core temperature, causing you to shiver.  This is experienced by Arctic/antarctic swimmers.  Once they get out of the water and into a warm bath or shower, their core temperature drops because their blood is running through relatively cool arms & legs.

It is because after eating the concentration of sugar in the blood increases which leads to ex-osmosis ie movement of water from the body cells to the blood where there is high concentration of solute. The movement of water from the cell results in the reduced metabolism which courses one to feel sleepy.

Your mouth feels dry because you are doing most of your inhaling through your mouth when swimming. The constant flow of air dries out your mouth and throat. If you swim in a pool, keep a water bottle at one end and hydrate yourself regularly. You lose fluids while swimming, whether you realize it or not.

to allow time for digestion\nif u dont wait, u may cramp up and u wont be able to swim if the tide takes u out too far.\n\n\n\nActually, the recommendation \nto wait an hour after swimming probably should be applied to most forms of \nphysical exercise/exertion.  When you eat and the food gets into the \nstomach and then into the small intestine (where most of the work of \ndigestion and absorption takes place), the body 'pulls' extra blood into \nthe body's middle (around the internal organs), so that the nutrients can \nthen be transferred into the blood and sent to the rest of the body.  \nSince you have a fixed amount of blood in your body, the amount of the \nblood that is left in the outer muscles must then be less.  So, you have \nless blood in the large muscles that you need for exercise...and that \nincreases the chances for muscle cramping (due to the production of by-\nproducts, such as lactic acid, which are toxic to the muscles).\n\n     Dr. Titchenal also mentioned that maybe where the 'old wive's tale' \nabout waiting for swimming, in particular, originated because when you are \nswimming you are usually face-down.  This might make you more prone to \ngetting sick to your stomach and throwing up, because of the stomach being \nfull and your face is in the water.  I wonder if anyone ever tested this \nafter eating by swimming face down and then swimming on his/her back?\n \n     So, bottom line:  it may be a good idea not to exercise for about an \nhour after eating (particularly a big meal), regardless of the exercise.
