We cannot imagine life without water, and even our body consists mostly of it (that is, 50–70% ). But do you really know how water affects health? Today, we will answer some of the most common questions about water!
What infections can you catch in the water?
Swimming in unfamiliar places might be dangerous, since there are plenty of pathogens, including harmful bacteria, in the water. For example, in pools and water parks you may catch Cryptosporidia which causes severe infection.
And in a bathtub bacteria Pseudomonas aeruginosa or Legionella may be found. The first one causes skin rashes and itching, and the second affects respiratory system. It can lead to Pontiac fever or Legionnaire disease. Also, do not forget about parasites.
While swimming, try not to swallow water, and always take a shower after.
How water affects health: Does cold or hot water reduce pain?
A study conducted in 2012 have shown that an ice bath after intense training helps relieve muscle tension. But this occurs only in comparison with rest. So, other ways to prevent muscle pain, such as stretching, running a bit, or having a warm bath, would probably work just as well.
In addition, hot water bottles or warm bath can temporarily reduce abdominal pain during menstruation.
Can swimming replace other types of physical activity?
To spend some calories and strengthen the body, you can surely start swimming regularly. Moreover, this type of physical activity involves more muscle groups than any other cardio exercise.
Other benefits of swimming include an increase in lung capacity, an improvement in the cardiovascular system, and a decrease in the risk of diabetes and mortality. In addition, it helps fight depression and anxiety, and does less damage to muscles and joints than a regular workout.
How water affects health: Is chlorine in pool water safe?
Chlorine used in pools helps kill harmful bacteria. At the same time, when swallowing pool water, you can catch an infection. Also, the acid HAA in water is potentially associated with cancer. Still, there is no need to worry: you just cannot get that much of it.
Personal hygiene: How often should you take a shower?
When talking of how water affects health, we most often ask how often we should take a shower. Normally, people have to take a shower or bath once a day. Mind that bathing too often, especially with cosmetic products and a washcloth, dries the skin. Furthermore, some insist that it makes the body more sensitive to harmful microorganisms.
How water affects health: Can a cold shower strengthen immunity?
Once, scientists have found out that regular cold showers lead to an increase in white blood cell count. Another study mentions that people who took a cold shower in the morning were 29% less sick than the control group.
Nothing proves that a cold shower can really improve the immunity, but it does not harm, too. Seems like in this case, cold water affects health in a good way.
Shower or bath, which is better?
When talking about the condition of the skin, then a shower can be better just because we spend less time in it. Also, it helps save the environment. But, in the fight against stress, both options will be good.
