Is it healthy for your skin to get into your pool at 12 pm
When the clock strikes noon, the environment of any body of water undergoes drastic changes. Beyond the well-known warning about ultraviolet (UV) rays and sunburns, there is an entire chemical ecosystem in the water that reacts at this specific time of day, significantly altering the impact the liquid has on the epidermis.
To understand whether this practice is beneficial or harmful to the skin barrier, it is necessary to observe what happens on a microscopic level when the sun reaches its zenith.
The Thermal Degradation of the Sanitizer
The lesser-known fact about water under the 12 p.m. sun is the invisible war between UV rays and free chlorine. Ultraviolet radiation acts as a natural destroyer of the sanitizer’s chemical bonds. In a body of water that lacks the exact level of cyanuric acid (the water’s sunscreen), up to 90% of the active chlorine can be annihilated by the sun in a matter of two hours.
What does this mean for the skin? By submerging at noon, a person enters an environment where the disinfecting capacity is at its weakest, allowing bacteria and microorganisms to proliferate rapidly, which increases the risk of skin infections or bacterial irritations.
Thermal Shock and Chloramine Formation
At 12 p.m., the ambient and water temperatures generate an inevitable physiological reaction: the accelerated release of sweat and body oils upon contact with the water. Sweat contains nitrogenous compounds, such as urea.
When this organic load suddenly enters the water, it reacts with the little remaining sanitizer and creates byproducts called chloramines. Most dermatological problems (redness, extreme dryness, and itching) that are usually blamed on an “excess of chemicals” are actually caused by these chloramines. At this time of day, the production of these irritating compounds skyrockets to its highest level due to body heat.
The Chemical Reaction of Sunscreens
Swimming at noon requires the generous use of sunscreens. However, a fascinating and harmful chemical reaction occurs on the surface layer of the skin. Very common ingredients in sunscreens, such as avobenzone, react directly with alkalinity levels and metallic ions (like copper or iron) microscopically present in the water.
This chemical fusion creates complexes that can not only stain swimsuits with yellowish tones but also alter the pH in the microenvironment of the skin’s pores. This translates into clogged pores and episodes of folliculitis that usually appear days after swimming.
The Surface Concentration Effect
The final phenomenon affecting dermal health at noon is the evaporation rate. As the sun heats the surface, water evaporates at an accelerated pace, but dissolved solids and chemicals do not.
This causes the first few inches of the water’s surface layer to develop a slightly higher chemical concentration than the rest of the deep volume. Right in that surface layer is where the skin of the face, neck, and shoulders maintains constant friction while swimming, exposing itself to a more aggressive environment for the natural lipid barrier.
In conclusion, the interaction between the epidermis and water at 12 p.m. goes far beyond simple sun exposure. Chemical instability, the accelerated formation of irritating compounds, and the neutralization of purifying agents make this hour the time when water presents its most hostile profile for overall skin health.
