At night, your kidneys filtrate less urine, and your bladder relaxes and holds more of it. Plus, a hormone called vasopressin instructs cells to retain water. So considering those factors, it's not surprising that your bladder may be quite full in the morning.
Hormonal Causes
The body produces an antidiuretic hormone at night called ADH, which slows the kidney's production of urine while you sleep. In people with enuresis, this hormone is not produced in significant enough quantities to slow the production of urine, which often leads to bedwetting.
It is not advisable to regularly hold urine, as it can result in problems. Holding in pee may cause a urinary tract infection (UTI), pain, bladder stretching, and more. The urinary bladder is a hollow, pear-shaped organ that forms part of the urinary system.
"When you drink less, the urine becomes more concentrated, and the more concentrated it is the more irritating it can be to the bladder, which can trigger the sensation that you have to go more often," Greenleaf says.
If you drink 8 oz. of water , it will usually be in your bladder within 20 minutes, so maybe a good idea to plan your void, if your bladder does not warn you. Also there is no health benefit to large volumes of water.
Any excess water you drink must be eliminated from your body in your urine (although we also lose a small amount of water through sweat and from the water vapour we breathe out from our lungs). In short, if you drink more water you will produce more urine.
First morning urine samples will normally contain the highest levels of hCG. C. If not tested immediately, urine may be stored at room temperature (59-86oF or 15-30o C) or 8 hours refrigerated at 36─46oF (2─8oC) for up to 3 days. Samples must be brought to room temperature before testing.
Quick Read Nature's worst alarm clock. It's normal to wake up once a night to pee, but multiple times a night could suggest something more. Nocturia is the clinical term for waking up to pee two or more times at night. Your lifestyle, medications and various health conditions might cause or contribute to nocturia.
Morning is when your urine will be most concentrated. So, if your morning urine is a pale, straw color, you're probably well hydrated and healthy. At bedtime, it should look as clear as water or at least pale yellow. If it doesn't, you may need to boost your fluid intake.
“It's a fact that urinary symptoms do get worse in the cold weather. As we tend to sweat less and, as a result lose less fluid through sweating, we produce more urine instead. So there will be a need to pee more.
Limit your intake of fluids two hours before bedtime
If you're struggling with nighttime urination, cut back to just one alcoholic beverage, or none at all, and decrease your current caffeine intake.
Levels of hCG will be strongest with first morning urine — more concentrated urine guarantees a more accurate test. Your test will still be valid if it's the afternoon or you've already had water, but first morning urine will result in a stronger results line. The stronger the line, the more accurate the test results.
First-Morning
Urine collected at the start of the day. First-morning samples are shown to be the most concentrated, and contain more proteins than urine collected in the afternoon and in the evening (1).
If urine is kept for a long time at room temperature, it will give an ammonia smell produced by the bacteria, which will decompose the urea in the urine.
Is clear urine always a good thing? In most cases, clear urine is a sign that you're well hydrated. And that's a positive thing because good hydration helps your body function at its best. But, in some cases, clear pee may mean that you're drinking too much water and you're too hydrated.
Drinking any type of urine can cause serious health problems unless it has been sterilized separately. Your urinary system specifically works to remove toxic substances from your body. When dangerous substances start to build up in your body, urine is one of the primary methods used to remove them.
Dr. Newton says a pigment called urochrome, or urobilin, causes the yellow color in urine. Your kidneys filter out this byproduct from your bloodstream and it exits your body in urine. The more fluids you drink, the lighter the color of the pigment in your urine. The less you drink, the stronger the color.
So whether it's part of your water-saving efforts or you can't stop the flow sometimes, it's pretty much fine to pee in the shower. Just make sure you are using your own shower. Since pee is supposed to be sterile and is made mostly of water, it likely won't have much of an impact on your or your shower floor.
A dysfunction in the diurnal pattern of antidiuretic hormone (arginine vasopressin [AVP]) secretion occurs in some elderly patients such that a reversal of diurnal fluid excretion results; urine volume at night increases and exceeds daytime volume.
Change your drinking habits
“Decrease fluid intake and decrease natural diuretics like coffee, tea and alcohol,” Dr Williams says. He explains this may help you to produce urine at a slower rate and may help your bladder “hold out” until morning.
