can anyone tell me what happens if you swim in water that has blue algae in it?

when i was 16 i did swim in a pool with lots of green algae, (not enough to really see, but more than normal,) and my hair definately had a serious green tinge to it for atleast 3 months. i don't know much about blue algae though.

Don't know sorry.  BUT PLS. I am at limit of questions for today so I ask here:  Is it dangerous if the pool's light is away from the wall and floating about a foot from wall and there is the cord to it in water? You know what I mean?  I've seen this a lot before . . .but the manitenance guy here is so stupid that I am particularly afraid this time.  Some other swimmer said it was OK and that it is always waterproof.

Ok, although the oil and dead cells on the surface of your skin are intended to restrict it as much as possible your skin is very slightly permeable to water.  If you were submerged totally in fresh water you would still dehydrate and die if you didn't drink, but maybe at a slightly slower rate than you might do otherwise.  Because of the osmotic potential of salt water you would probably LOOSE (a very small amount of) water from your tissues to the surrounding water!

Not really harmful.But the oxygen in the body is used up to burn the food u eat, thus u might feel a little drowsy due to less oxygen, n u might drown(yeah a little far fetched but u might-little kids n all),n u just might need a lifeguard, so u just might consider NOT eating b4 swimming....

Depends on the plant.  Some plants, like kelp or Utricularia thrive when totally immersed.  Others cannot transpire properly unless their leaves are exposed to air, and will 'drown' in water.

no. But when the body is put in water it cause the snapese to fire and cause the bladder to react?

I'm not sure exactly what you're asking, but if you put a few drops of food coloring in the water with a white flower (like a carnation), it will absorb the dye and the color.

Next time you're in the pool take a deep breath while wading towards the deeper end. Don 't paddle. You may not stay upright but you will stay at the surface. Now as you're floating there let all that air out of your lungs, you'll start to sink...Just a little exercise...But after a body dies and decomposes in the ocean, gases are made in the body due to decomposition process (such as carbon dioxide, methane and others) these gases fill the corpse causing a "bloating" and the body will then come to the surface. Thats why gangsters used to make "concrete shoes"...

my guess is that the burning is from irritation.  next time you might wanna have more water in the pool before you go swimming.

Chlorine has bleach in it. No one would ever think of washing his or her hair in bleach, but that's what you're exposing yourself to every time you  jump in the pool. I don't know about premature aging, but chlorine dries the skin severely and therefore, extra care should be taken before and after you swim.\n\nBefore I swim, I put a light coating of conditioner in my dry hair. Then I put on a cap. This protects my hair somewhat from the damaging effects of chlorine. If I'm swimming outdoor in the daytime,  I always, always wear sunscreen. Be sure not to miss the back of your body, since you tend to expose your posterior to the sun when swimming. This is the single most important thing you can do to protect yourself from longterm damage (not to mention skin cancer).\n\nAfter swimming, I wash my hair and condition it immediately. I shower to get all the sunscreen off, then while I'm still drying off, I put lotion on my entire body and moisturizer on my face.

Its probably false but Ive been told if you swim immediately after eating you can get cramps caused from blood leaving the body parts in motion and going to the stomach to digest causing cramps in the body parts in motion

It is an old wives tale. The oly way it could really harm you is if you're a competitive swimmer, and you eat a big meal. Then you risk cramping.

I would say probably not, but check with your doctor. The spill might have other adverse effects on your health.

Depends on the individual, and where you swim.\nPools don't cause any harm, as long as someone is watching and adjusting the water chemistry.  Swimming laps will make you feel livelier and better off, and you'll get into better physical shape.\nBe careful if you swim in the sea.  Watch for rip tides, and know what to do if you're caught by one.  Check with the local authorities to see if the water is bacteriologically contaminated.\nFresh water swimming is generally safe.  Just use common sense.\nUse sunscreen if you plan to be in the midday sun for a while.  Swimming tends to wash it off; reapply if necessary.

It could depending on what you have had to eat. If you eat or drink something with blue coloring in it, it can turn blue.

Tropical seas are usually a lighter blue colour because they are clearer than water at higher latitudes.\n\nWanna know why?\n\nIt’s because dead animals and plants sink in water. That might seem obvious, but it means that any nutrients in sea water are rapidly used up by animals and plants and when those organisms die they sink to the bottom taking the nutrients with them. The only way those lost nutrients can be replaced is if water form the ocean bottom, where all those dead organisms go, can be moved to the surface again.\n\nThat cycling can’t happen in tropical regions because the surface water is warm and warm water floats on the cold water of the ocean bottom. As a result tropical waters very rapidly become nutrient deficient.\n\nBecause they are nutrient deficient very little actually lives in tropical waters. Very few algae, very little plankton and so forth. And because nothing much lives in tropical waters they remain clear. That means that light can get go waayyy down into the depths, and as light passes through the water the blue wavelengths get scattered. That produces a vivid turquoise blue ocean.\n\nIn contrast cold waters are dirty and full of life due to the upwelling of water from the ocean bottom. All that dirt and all the life it supports absorbs sunlight very fast. Light will only penetrate a few metres in cold waters. With very little penetration the light also doesn’t have much chance to scatter. That produces an ocean that is very dark coloured, and where the blue wavelengths are muted by the reds and greens to produce a muddy blue-gray.\n\nSo what it all comes down to is that tropical waters are clear, and they are clear because they are sterile and nutrient deficient. Coral reefs thrive in tropical waters precisely because they are clear and sterile and that allows enough sunlight for the photosynthetic symbiotic algae that live in the coral and that provide most of their food.

i wouldn't recommend swimming in nature right now. a lot of debris was blown all over the place, and they're still cleaning it up. you could get hurt badly by something submerged under the water, like metal or a broken board, glass, etc.
