This study is another nail in the coffin of the idea that the sun causes you to get skin cancer.
In fact, the results of the study could not be more clear.
The study shows us why people live longer who are getting more sun exposure.
It shows us why people who live in the far north and far south tend to die sooner younger.
Does avoiding sun lower your lifespan?
Actually, it just might.
It turns out that it’s because they don’t get enough sun all year round.
And it’s about how the more sun you get, the healthier you are.
This kind of study is called a prospective study.
Researchers didn’t actually take a randomized group of people to perform this study.
They didn’t divide people into two groups, and expose one group to the sun, and restricting the other group to indoors without sun.
What researchers did was to look back at records of a big study that was done in the past.

They looked at how much sun the participants of the first study received in a period of 20 years.
That study had over 20,000 people participating, so there was a great data set.
And researchers looked to see how many of those had died.
Mortality was twice as high for the son avoiders.
This is an incredible increase in mortality.
In general, the more sun a person receives, the lower their death rate.
This study only worked with women — but I have no doubt the result is exactly the same for men.
The study only evaluated the sun exposure of the participants.
They didn’t evaluate things like vitamin D levels.
So there could be other factors at play in addition to sunshine.
But the fact is, that you need sun.
Getting enough sunlight for health is important.
So there really are health benefits of sunbathing.
The more sun, the better for your health.
In fact what you really need especially is red light.
Red light and what is called infrared or near infrared light are what you really need.
This light has huge benefits that are covered in another newsletter.
But it’s also the light in the sun’s light that is mostly responsible for longer lifespans.
You can buy red light devices to use in your home or office.
Then you can be exposed to red light all day as you work, and reap enormous health benefits from it.
It’s a substitute for getting enough sun, and it can be a great help if you spend a lot of time indoors, or live in a climate that doesn’t get a lot of sun.
Red light doesn’t cause you to get sunburned either.
It turns out that some sun exposure is very desirable.
But I don’t think it’s a good idea to get sunburned.
If you can get more sun without the sunburn, you should.
