When people talk about the sun, they’re usually talking about heat 🔥
We’re told to stay out of the sun because we can get sunburn and that it can lead to skin cancer.
Both of these things are true.
But like many health related topics, that’s not the whole story. More on this in a minute..
While the focus is on heat from the sun, we are distracted from all the benefits of LIGHT from the sun.
Let’s dig in.
Sunlight provides incredible benefits in the following ways:
- Brain health.
Exposure to sunlight results in the production of serotonin which improves mood, and lessens symptoms of depression and anxiety. It also helps regulate your circadian rhythms, which improves your focus and alertness during the day and help you sleep better at night.
- Gut health.
Sunlight is crucial for mitochondrial health and immune system function.
Of course, Vitamin D is the big player here. It governs nutrient absorption, reduces inflammation, balances gut microbiome, strengthens the gut lining and promotes cell repair.
Inadequate levels of Vitamin D are associated with poor immune response (do you get sick every flu season??) and an array of gut issues such as IBD.
- Metabolic health.
Sunlight exposure produces Nitric Oxide which opens up blood vessels and reduces blood pressure. It also improves insulin resistance and fat oxidation.
- Hormone health.
Sunlight helps regulate cortisol, balances oestrogen and boosts testosterone, produces thyroid hormone, and helps production of melatonin (your natural sleep aid).
- Reduces cancer risk.
No, you didn’t read that wrong 😳
An ever-increasing amount of studies are revealing that increased exposure to sunlight results in dramatically reduced risk of breast, colon and prostate, lung cancer - and even melanoma via Nitric Oxide and Vitamin D pathways.
So, does this mean we should just be out in the sun all day?
Of course not.
Sunburn is the real deal and can 100% lead to skin cancer and many other issues.
But did you know that things like consumption of seed oils greatly increase the risk of skin cancer? A comprehave study in 1988 from right here in Australia 🇦🇺 brought this to light. 🤔
So like everything else health related, your diet can either increase or decrease your risk of disease.
Now, how do you get the benefits without exposing yourself to extra risk?
Here’s my 2 cents 🪙 🪙
* Get your exposure when the sun is bright, not hot. The 2 hours after sunrise or the hour before sunset is the perfect time.
* 20 minutes a day is enough to provide noticeable benefits. Start having breakfast or your morning coffee outside to start the day and you’re all set.
* Wear short sleeves, or no shirt (probably just the fellas actually😬) to increase the exposure through your skin, and don’t wear sunglasses - your eyes have vitamin D receptors which trigger absorption, and these are blocked by wearing sunnies.
* When it’s hot - that’s the time for long sleeves and wide brimmed hats. Stay out of the heat and avoid sunburn.
If all this ⬆️ ⬆️ is too wordy, then just try this..
Tomorrow, spend 20 minutes in the morning sun having a coffee or reading the paper. If you don’t go inside afterwards feeling better than when you walked out, I’ll eat my hat.
Hopefully, after getting some more sunshine into your days, you’ll start to see the light 😉
