Why does the sea make us tired? This is a question that many people feel during summer vacations. It's not just a feeling: it's physiology, writes focus.it.
Even though it's a quiet day at the beach, lying on a sun lounger, the sun and the sea still leave us exhausted.
According to researchers, our bodies, exposed to environmental conditions very different from those of urban areas, activate various adaptation processes that require energy.
Vasodilation and increased sweating help regulate body temperature, but they lead to the loss of fluids and mineral salts such as potassium and magnesium, essential for muscles and the nervous system. This leads to dehydration and fatigue.
Sea air, richer in oxygen and iodine, stimulates metabolism and the thyroid, contributing to increased appetite.
Melanin production, activated by UV rays, is another "invisible" process that consumes energy.
Moving through water also requires more effort: the density of the sea and the resistance of salt increase energy expenditure.
Finally, there is a positive side: the sea is relaxing. It stimulates serotonin, endorphins, creativity, and reduces stress, anxiety, and eye strain.
The key is to stay hydrated: water, fruits and vegetables help fight fatigue… and really enjoy the sea.
