Seawater’s Health Benefits

The sea has long been a favorite destination for individuals seeking to treat different ailments and for convalescent patients.

In the 19th century England, seawater baths gained popularity as an unconventional convalescence treatment for an assortment of ailments, which range from melancholy to respiratory ailments. Patients have been told to devote some time by the sea or to enter baths filled with seawater to help them return to health.

The foundation of utilizing seawater in medicine goes back much longer, however. There’s evidence, for example, the Ancient Egyptians used it in the treatment of severe wounds and burns. To this very day, the amount of scientific literature on the subject remains quantitatively significant, but the quality of the evidence concerning sea water’s curative benefits varies broadly. The majority of the research has focused on its effect on skin ailments and mental health.

Seawater and skin ailments
For several decades, anecdotes of people with psoriasis locating relief from spending some time in salt baths or more generally, in mineral-rich water, have been reported. Even the Dead Sea, in particular, is famous for its high levels of calcium and has been a favorite destination for people who wish to try out an alternative treatment course to help handle their skin condition.

A study published in the Journal of the American Academy of Dermatology showed that patients who have chronic, stable, plaque-type psoriasis benefited from spending some time in the Dead Sea, taking sea baths, and getting sunlight exposure, which led to remission periods lasting over three months normally. These results were then backed up by subsequent and more recent studies, although none explained which components of seawater, if any, had this effect.

“Any progress observed after swimming in the sea could be explained by exposure to UVB rays from sunlight as this may improve skin conditions, such as psoriasis.

A huge inspection zoomed in on different trials of seawater therapy and found that eczema patients’ responses to seawater and salt baths, in general, were highly variable.

“Research about the benefits of seawater on inflammatory skin conditions is very limited. There’s some evidence to suggest that water from the Dead Sea can help to improve eczema flares; however, most evidence is anecdotal,” Rai explains.

It’s also possible that it’s not merely seawater per se that is having an impact. It might be that being in a new environment, using another climate, by the shore, is what helps some patients.

The mainstay of treatment for eczema and psoriasis incorporates topical therapies and biologics in the event of psoriasis, says Rai.

Improving your mental health
This type of study has grown in popularity lately, in particular, as a result of the launch of BlueHealth, a pan-European research initiative investigating the connections between environment, climate, and health. In particular, scientists in the program consider how the sea along with other water-based environments can impact well-being.

There’s ample evidence to suggest that physical exercise is quite beneficial for mental health, specifically, to control stress and anxiety, partly because it encourages the release of endorphins (the feel-good hormones).

This, based on the study, appears to be much more true for people who exercise in natural, outdoor environments, including the ocean.

“Outdoor exercise, such as swimming at the sea, maybe especially valuable and some research suggests that outdoor exercise in this way can be as effective as antidepressants in treating mild to moderate depression. The mental health charity also explained.

But swimming in the sea may also help mental health via other mechanisms. When we are swimming, our breathing patterns change, which might result in a more relaxed state.

Suggestions to enjoy the sea’s benefits

Protect yourself
Don’t forget that sea generally means sunlight, and both sea and sunbathing have been linked to improvements for the skin. But get decent sunscreen too. “It is important that individuals make sure they remain protected whilst outside in the sun, due to the possible danger of developing skin cancer,” Rai says.

Do not stop taking your meds
Even if you decide swimming at the sea does help you, don’t stop the other remedies you are taking. In case you have concerns and want to change anything on your treatment program, talk with your doctors first, to get their advice.

Find an activity you enjoy

Select the physical task that works for you.

“While swimming in the sea attracts benefits for mental well-being for a lot of people, the most essential thing is to find a type of physical activity you enjoy and can do regularly. An outdoor swimming team or other team action might be ideal for you if you find being sociable provides you a boost, while others who gain from yourself, a task like running may do the job better,” Buckley says.

The Health Advantage of Some Sun Sunlight

Sunshine is a mixed blessing. There is no question that it can be a danger to your skin. But moderate sun exposure may have benefits for your health, including stronger bones, better sleep, enhanced mood, along a healthier immune system.

And when you continuously protect yourself from sunlight or constantly cover every inch of exposed skin with hydration, you could be missing out.

Since the evidence grows that sun exposure has benefits, many experts are rethinking their staunch sun avoidance advice.

By way of instance, despite Australia having one of the highest skin-cancer speeds on earth, Cancer Council Australia recognizes that some time in the sun without sunscreen or other defense is crucial, according to Robyn Lucas, Ph.D., a professor at the Australian National University College of Health and Medicine, that investigates environmental consequences on health.

And the National Academy of Sciences recently assembled a global group of medical specialists from different areas to talk about sun safety.

Bone Health and Beyond
The best-known benefit of sun exposure is vitamin D synthesis, which happens in the skin in response to the sun’s UVB rays. Vitamin D is a critical nutrient.

But the sun may play other roles in promoting good health too. The research is ongoing, but so far studies indicate that UV exposure might lower blood pressure (which helps to protect against heart attack and stroke), curb appetite, and reduce the risk of obesity, type 2 diabetes, obesity, and possibly certain autoimmune disorders.

Sunshine may likewise be linked to longevity. A Journal of Internal Medicine study that monitored nearly 30,000 Swedish women for about 20 years found that people who spent more time in the sun lived six months to 2 years more than those who awakened with less sunlight exposure. “More research is required to replicate this work, but if it’s a true effect, it is very important,” Lucas says.

But the UVB rays that assist our skin produce vitamin D is also the same kind that causes sunburn, and getting burned is a major risk factor for skin cancer. That is the reason it’s so essential to find the ideal balance.

Short Stints Do the Trick
To determine the duration of time you may stay in the sun without burning, Lucas suggests using the UV index, which predicts that the degree of solar radiation in your area on a scale of 0 to 11. To locate the UV indicator for any particular day and time in the U.S., enter the ZIP code of the area you’re in on the Environmental Protection Agency’s website.

To figure out the right UV dose for you, divide 60 (as in the number of minutes in an hour) from the UV indicator to learn the number of minutes outdoors it takes for you to receive 1 SED. SED stands for “standard erythemal dose,” a predetermined dose of sunlight intensity that will lead to erythema or reddening of the skin.

See the table below for the approximate SED it requires for different skin types to burn off. For example, if the UV index is 7, then divide 60 by 7 to get 8 minutes for 1 SED. If you are honest, you will receive sunburned with two to 3 SED (16 to 24 minutes).

“These numbers are a generalization of skin kind by ethnicity,” Lucas says. So it is ideal to be conservative with them. In the above example, for instance, to be on the safe side you might go in the sun unprotected for 12 minutes maximum.

Most significant, always err on the side of security. “You don’t even want to obtain a little pink, because UV exposure that’s sufficient to cause sufficient damage to skin obviously outweighs the benefits of that vulnerability,” states Robert S. Stern, M.D.

Keep in mind, also, that the amount of time you may spend in the sun without burning on a specific day doesn’t reset to zero with subsequent time outdoors. “If, as an instance, the calculation you workout involving the UV index is 15 minutes, that should be your complete limit for daily –if that is in one sitting or a couple of sittings,” Lucas says.

Permit From the Light
When heading out to soak up some sun, Lucas recommends applying sunscreen to your face and hands (they’re always getting sunlight and therefore are at elevated risk for skin cancer, wrinkles, and brown spots), sporting a broad-brimmed hat and shades, and exposing what you can of your own arms and legs. If you’re especially sun-sensitive (for instance, you have had skin cancer if you simply take a medication–for example certain diuretics and antidepressants–that raises your risk of sunburn), talk to your physician before visiting sunscreen.
