The Importance of Sunshine

The Importance of Sunshine

While exposure to sunlight generally gets a bad rap in terms of increasing the risk of sunburn and skin cancer, some sun exposure is important.

 

Daylight saving is about to come to an end here in New Zealand. Our clocks will go back 1 hour resulting in lighter mornings and darker evenings.

For those of us who don’t rise at the crack of dawn and who spend most of our working day indoors, this change in daylight hours means we have less time available to get outside and enjoy the natural sunlight.

While exposure to sunlight generally gets a bad rap in terms of increasing the risk of sunburn and skin cancer, some sun exposure is important. Particularly during the cooler months when it can be tempting to rug up and stay indoors.

  • Sunshine is believed to have a positive effect on our production of serotonin, which can help nip those winter blues in the bud.
  • Your circadian rhythm (also known as your sleep/wake cycle), is basically a 24- hour internal body clock that cycles between sleepiness and alertness. To maintain a normal circadian rhythm and get a good night’s sleep, spending time outside in daylight is vital.
  • Vitamin D is important for enhancing our absorption of calcium from the foods we eat. This calcium is essential for the health of our bones. Vitamin D status is largely maintained through our exposure to sunlight, and seasonal changes can have a significant impact on the ability of our skin to produce vitamin D.

A daily 30 minute walk or other form of outdoor physical activity around the middle of the day is recommended between the months of May to August. If possible, have your face, arms and hands in the sun to maximise the exposure of skin to sunlight, activating vitamin D.

For those needing supplementation, Healtheries Vit D 1000IU Capsules give you high-strength active Vitamin D in a one-a-day, easy-to-take capsule. Each capsule also provides important bone health minerals Boron and Selenium.
