With this new fear, the industry of blue-light-filtering glasses has emerged over the last few years.

Information overload
  • Information overload was a term coined in the mid-1960s by Bertram Gross, a social scientist.
  • In 1970, writer Alvin Toffler popularized the idea of information overload as part of a set of predictions about eventual dependence on technology.
  • Another set of academics wrote that information overload occurs when the amount of input exceeds its processing capacity.
  • A 2011 study found that on a typical day, Americans were taking in five times as much information as they had done 15 years earlier.
  • A 2019 study identified that our attention span is shrinking, probably because of digital overload.
Technology pushed too much

It is probably too late to restore our attention span to that of our grandparents. After a decade of smartphone use and social media, the harm is perhaps irreversible.

Part of the problem in this age of overload is the constant insistence of notifications that seeks our immediate attention. When the body jumps to attention and for nothing of particular worth, it can be confusing.

Keep in sync with your body’s natural sleep-wake cycle
  • Try to go to sleep and get up at the same time every day;
  • Avoid sleeping in, even on weekends;
  • Limit naps to 15 to 20 minutes in the early afternoon;
Melatonin

Is a naturally occurring hormone controlled by light exposure that helps regulate your sleep-wake cycle. 

Your brain secretes more melatonin when it’s dark, making you sleepy, and less when it’s light, making you more alert. 

However, many aspects of modern life can alter your body’s production of melatonin and shift your circadian rhythm

Influence exposure to ligh

During the day:

  • Expose yourself to bright sunlight in the morning. 
  • Spend more time outside during daylight.

  • Avoid bright screens within 1-2 hours of your bedtime.
  • Say no to late-night television.
  • Don’t read with backlit devices. 
  • When it’s time to sleep, make sure the room is dark.
  • Keep the lights down if you get up during the night.

Things worth prioritizing in life

There are some general areas that all of us should prioritize in order to function well and generally make life worthwhile. These areas are:

  • Health and fitness. Bad health and fitness habits add up over time and have a knock-on effect in other areas of our lives.
  • Sleep and rest. Inadequate sleep leads to unstable emotions, impaired learning, imbalanced hormones and a compromised cardiovascular system.
  • Friends, family, and relationships. It's hard to mend relationships once they've been frayed. Be proactive about being the connector and decide beforehand what you won't miss out on.
  • Productive work. Instead of working harder, we should work smarter (more strategically.)
Things to deprioritize

Intentionally take your focus away from distracting areas in your life.

  • Social media and entertainment. While they can add fun to our days, it's worth reducing how much time we spend on apps.
  • Busy work. These are tasks we do regularly but that fail to move us forward. These tasks should be delegated, automated, limited, or deleted.
  • Negativity. When we focus on the negative, we are prevented from seeing reality clearly. It is then important to be aware of your inner thoughts. Maintain a running record of positive things people say about you.
