As my initial research for looking in to health benefits of the seaside, I used Google to find out some basic information. I came across this article from the Daily Mail.
Research shows that the sound of waves alters wave patterns in the brain lulling you into a deeply relaxed state. Relaxing in this way can help rejuvenate the mind and body.

Also, floating in water means blood is diverted around from our lower limbs and pumped towards our abdominal region - the part of the body near the heart - because we are no longer standing upright. Fresh blood being pumped around the body brings more oxygen to our brain which makes us more alert and active.
Fresh air for sleep
If you've ever wondered why we always sleep more soundly after spending the day on the beach, it's because of the sea air. Sea air is charged with healthy negative ions that accelerate our ability to absorb oxygen. Negative ions also balance levels of seratonin, a body chemical linked with mood and stress. Which is why after a holiday you feel more alert, relaxed and energised.

I found this really interesting and it led me to my next research on Martha Gunn who was a 'dipper' - someone we will be looking in to for the cause of the documentary.
