I am a believer that people should try to learn at least a single current thing each day, then this week, I l earned the difference between a semipermeable membrane, a single that allows particles to pass through it based on size, plus a selectively permeable membrane that somehow decides or “chooses” what will pass through it.
The best example of the latter is human skin, the body’s largest organ plus the protective layer that covers us from head to toe.
This amazing substance has an enemy that can’t be avoided, plus that is Heating plus A/C, but air conditioning has been a miracle since its 1902 invention; It first revolutionized workplaces needing humidity control plus made living in arenas love FL bearable. The complication is that its effect on our skin can be devastating, however skin needs moisture to stay healthy plus the lower humidity in a room heated or cooled with dry air will make the skin shriveled plus itchy. Skin can also lose its elasticity plus ability to regenerate. That is a single reason why skincare products that ward off the damaging effects of Heating plus A/C are a multi-billion-dollar industry, and before we pile too much blame on Heating plus A/C for our wrinkles plus other skin ailments, consider that Mother Nature has been damaging people’s skin since the dawn of civilization. The effects of the sunlight are well documented, plus dozens of sun-blocking lotions are available to prevent damage from harmful UV rays, people in cold weather conditionss often suffer from the dry itchy Winter time air that sucks the moisture from the skin. The superb news is that humidifiers can keep a room’s humidity at reasonable levels to prevent skin damage. Applying moisturizing skin lotions is a small price to spend my money to prefer the benefits of Heating plus A/C that include our year-round comfort plus getting a superb night’s sleep.
