You are probably aware that on Sunday at 2:00 am, the time will jump forward one hour. If you didn’t re-set all your non-automatic clocks and devices before you went to bed, you’ll wake up Sunday morning an hour behind.
So re-set all your timepieces so you can get an extra hour’s sleep Sunday morning!
However, there are more benefits to Daylight Saving Time than a Sunday sleep-in or extra hours of late afternoon daylight. Start with the science of the connection between vitamin D, osteoporosis, prostate cancer, heart disease and depression.
First, D is not actually not a vitamin, but a chemical complex that is vital to both mood and physical health. Scientists are excited about new studies that show how important the D complex is in the human body. It creates bone density, preventing osteoporosis. It regulates cell growth, which plays an important role in prostate cancer because prostate tissue has a huge supply of vitamin D receptors, helping these tissues to absorb and use the enzyme that prevents the wild multiplication of cancer cells. New studies show that men with high levels of vitamin D in their blood have 45% less risk of developing aggressive prostate cancer than men with low levels of the D complex.
In fact, deficiencies of vitamin D are now  being linked to cases of multiple sclerosis, some forms of heart disease, foot and ankle injuries, brittle and thus easily fractured bones, unexplained muscle pains and  weakness, and SAD, or Seasonal Affective Disorder; a form of depression that happens in winter, as well as clinical depression and mental decline in older adults.
How does this relate to Daylight Savings Time?
The answer is startling: This nutrient only comes from three sources: fish, egg yolks—and sunshine. Many foods are fortified with vitamin D, but regardless of these limited available sources, the chemical complex known as  ‘D’ must be transformed inside the body before it can be used BY the body.
That’s why direct exposure to sunshine is so important. It’s also why our modern lifestyle can be so destructive when it comes to obtaining sufficient amounts of this essential nutrient.
Modern human spend most of their lives shut away from the sun; whether in homes, offices or places of  business. When we do  go out in the sun, we usually apply sunscreen, which  effectively blocks the energy of the sun from contacting our skin,  where it would  ordinarily be converted to vitamin D. That’s why D is called the ‘sunshine vitamin.’
Now we come around full circle to Daylight Saving Time. With DST, we get more exposure to sunlight. That boosts our body’s supply of valuable vitamin D. You don’t need a lot of sun exposure to prevent deficiency. Just a few minutes a day of sunshine on your arms and face will do the trick.
Of course, if  you spent most of your day inside, and block the sun  with  sunscreen when you’re outside, you can use vitamin D supplements to make sure you have enough of this important substance in your system. In fact, many people have found that taking twice the recommended daily dose of this ‘vitamin’ makes them feel happier, curing clinical depression they never suspected they had.
This time of year is the perfect time to recognize that the sun is your friend. So is Daylight Saving Time.
