Happy Summertime to all of us who live in the Northern Hemisphere!πIn addition to yesterday being Father's Day, it was also the official first day of summer and the longest day of the year!
Without the Earth's tilt, the amount of daylight would remain nearly constant throughout the year. As the Earth orbits the sun, it spins on a tilted axis fixed at 23.4 degrees.πIt is this tilt that causes the amount of sunlight that reaches different parts of the Earth to change throughout the year.
In the summer, the northern hemisphere is tilted towards the Sun so Earth experiences its longest days. At the summer solstice, the northern hemisphere is tilted almost directly toward the Sun and the Sun appears exactly overhead at the Tropic of Cancer.
Here are some interesting facts & folklore from The Farmer's Almanac:
What is the Summer Solstice? - in the northern hemisphere, the solstice occurs when the Sun travels along its highest and northernmost points in the sky. This marks the astronomical start of summer in the northern half of the globe. In contrast for those living in the Southern Hemisphere, the Sun is at its lowest point in the sky marking the start of winter.
Does the Solstice Always Occur on the Same Date? - the June Solstice is not based on a specific calendar date or time. It depends on when the Sun actually reaches its northernmost point. The date may shift between June 20-21-22.
Is it the Longest Day of the Year? - yes, the Summer Solstice is the day with the longest period of sunlight. The Sun is at its highest point in the sky and it takes longer for it to rise and set. When you are outside, notice how the Sun appears highest in the sky. Its rays strike Earth at a more direct angle, causing the efficient warming we call summer.
During the summer months, the warm weather, increased sunlight, and extra time spent outdoors come together to have a powerful impact on both our physical and mental well-being. Some of the positive effects of summer include increased Vitamin D levels, lower stress, being more physically active, and making healthier food choices adding more fruits and veggies.
Let's all try to carry these healthy summer habits of walking more, eating fresh food, and taking time to rest into the remainder of the year. We might find ourselves feeling healthier year-round.π
