SEA AIR is some of the purest air on the planet and has long been a go-to-remedy for anyone with a respiratory condition. The smell of the seaside is caused by dimethyl sulphide gas, given off by the sea, and not ozone (a form of oxygen). And getting a lungful at the beach will help you to sleep better.
This is because sea air is full of negative hydrogen ions, charged particles abundant in sea spray and concentrated in fresh air, which improve our ability to absorb oxygen by neutralising damaging free radicals (positive ions). These negative ions can also balance levels of seratonin, the feelgood hormone, making us less prone to anxiety.
