Well-Being, Today and Every Day


Since the COVID-19pandemic, how we work, live, and connect has changed dramatically.
With social media available 24/7, we can access information anytime, and smartphones havebecome essential—so much so that terms like“smartphone addiction”and“digital detox”arenow part of everyday language.
Overuse of digital devices can cause eye strain, headaches, stiff shoulders, and dry eyes fromblue light. More seriously, it disrupts our biological clocks, lowers sleep quality, and stressesthe brain—affecting memory and judgment. Electromagnetic waves are also a concern. Butrealistically, we can’t just stop using computers and smartphones, no matter how bad theymay be for our bodies. Still, continuing without change feels irresponsible.
Personally, to mitigate the negativeeffects of blue light, I avoid using computers orsmartphones in dimly lit areas and try not to stare intently at screens. To prevent informationoverload and stress, how about acquiring accurate knowledge and making an effort to improvethe quality and quantity of our sleep?
“Sleep” can easily be made part of our lives. It helps rest the body after daily activity, recoverfrom fatigue, and repair cells. It is also essential for the brain—consolidating memory,refreshing the mind, and maintaining emotionalbalance.
Beyond rest, sleep also regulates autonomic functions, supports hormonal balance, andstrengthens the immune system. Good sleep lowers the risk of lifestyle diseases like obesity,diabetes, and heart disease. Clearly, good sleep is key to good health.
I avoid screens for1–2hours before bed, limit late-night screen use for work, and keep myphone out of the bedroom.
To reduce electromagnetic exposure, I unplug nearby cords and wear an EMF-protectionnecklace. I also manage my core body temperaturerhythm to improve sleep quality. Becausea drop in core body temperature leads to better sleep, I take my bath two to three hours beforebed. The bath raises my temperature, which then gradually drops—creating the ideal momentto drift off to sleep, so Imake sure to be in bed by then.
The biggest change I’ve noticed is how I wake up—my mind and eyes feel clear.This experience made me realize that by learning how our bodies work and adjusting ourlifestyles accordingly, we can better adapt to our rapidlychanging world, and by being mindfulto eliminate things that are bad for our body, we can improve our quality of life.
