Preppers Knowledge Bank: Winter Blues, Seasonal Affective Disorder, or Sunlight Deprivation

Sunshine Fights DepressionAll humans, and most animals, need a certain amount of sunlight to survive.  If you are a prepper who plans to use a bunker or be a cave-dweller , it is important to take this into consideration.  Spending large amounts of time in dimly lit areas can bring about situations scary movies are made of.

The human body needs one hour of sunlight a day to survive.  That’s survive.  That doesn’t include a condition better than mere survival mode.  It has long been known Vitamin D prevents many diseases, but beyond that most people don’t know the “list”.  Indeed,the list is quite long.  It includes such things as improvements in asthma to bone health and can kill bad bacteria and improve heart health.

Whether you want to call it “seasonal affective disorder” or “winter blues” it can be depression brought on by lack of sunshine.  For some people, just being outside will quickly improve their mood.  The need to be outside is natural as evidenced by the number of outdoor fun activities people engage in daily.

But, what does being outside mean?  If I cover myself from head to toe with no part of my body exposed to the sun, I might as well stay indoors.  The same is true if I cover myself with harmful sunscreen products.  The benefit of the sun are blocked along with the negligible hazards.  Consider that 65,000 people world wide die of skin cancer.  Now consider that globally almost 1.24 million people die in traffic accidents.

No matter what, make certain every member of your family gets enough sunshine when the getting is good.  What if the sun isn’t available due to shortened days or being indoors most of (or all) of the time?  There are vitamin D supplements to prevent diseases by providing  vitamin D in the blood to allow the immune system to function.  Without Vitamin D your immune system can not function.

Installing full spectrum light bulbs are useful in replacing some of what you are missing and are certainly better than nothing.   Simply turn it on and enjoy a book, or better yet, this website.  Full spectrum lights are available at Lowe’s and Home Depot as well as other hardware and home improvement stores.  When preparing for a SHTF event, also consider adding a “sunrise” light to to wake up naturally.  It will improve and encourage a natural sleep pattern.  Combining the full spectrum light with the natural sunrise light, you’ll have your days and nights covered.
