20-5-3 The Three-Number Formula for a Healthier You!


The beginning of each calendar year gives us the opportunity to set some goals: and many of us do a mental run-through of various ways we might be exercising and moving differently in the new year. According to Rachel Hopman, Ph.D., a neuroscientist at Northeastern University, Americans today spend 92 percent of their time indoors, and their physical and mental health is suffering.


Dr. Hopman subscribes to something she calls the 20-5-3 rule. If you think of it as the food pyramid, except instead of recommending that you eat this many servings of vegetables and this many of meat, use the visual to determine the amount of time you should spend in nature to reduce stress and be healthier.


Here's How it Works:


20 Minutes

That’s the amount of time you should spend outside in nature like a park, the boardwalk, a hiking trail – 3 to 4 days a week. That’s it, 20 minutes outside is the dose of nature that has the greatest effect on reducing stress and producing a mental state of peace. But turn off your phone—alerts from it can be disruptive and negate your efforts.

5 Hours

This is the middle of the pyramid and reflects the minimum length of time each month you should spend outdoors in a designated activity aligning with nature.

Which we know affects both the mind and body - stimulating and soothing us in unusual and unique ways.

3 Days

This is the top of the pyramid. Three is the number of days you should spend each year off the grid in nature, camping or renting a cabin (with friends or solo). Think places characterized by spotty cell reception and wild animals (but don’t forget the bear spray), away from your desk and the hustle and bustle. Think of it as an extended meditation retreat - except talking is allowed, you don’t have to sit crossed-legged, and you can bring your own! This step can reset your thinking, boost creativity, tame burnout, and just make you feel better.

Between the pandemic, working from home, the economy, or other factors of busy lives, you may be feeling over-stressed. As a result, making time to focus on reducing stress levels using the simple 20-5-3 in the coming year is an easy way to make this happen. Use this three-number formula to make yourself stronger and happier.

of NJ, PA, and NY, plus explore an Atlantic cedar swamp.

Mt. Tammany – Delaware Water Gap

Climb steeply uphill to a fantastic overlook of the Delaware Water Gap and

Mt. Minsi across the way.

3.5 miles. Rocky, steep. Short in length, but strenuous due to steepness. Rock scrambling.

The return trail is less steep but still very rocky. This loop goes up the RED DOT trail

and returns down the BLUE trail. We recommend this way as the rock scrambles on RED DOT are a bit harder to negotiate going down.

Easier variation: Up/down on BLUE. Miss a view on the RED trail and it’s a less interesting hike – but it’s easier and arrives at the same viewpoint.

Shorter but still steep: 1.0 mile, to the first viewpoint and return.

Easy/short variation: 1.2 miles, instructions below. Waterfall only, no summit.


Stairway to Heaven - Sussex County

A short but very steep hike to Pinwheel’s Vista.

rom Pinwheel’s Vista.
