Can THIS Predict How Long You’ll Live (BETTER Than Diet or Exercise)

I used to have patients who would just kind of shrug their shoulders when I’d talk about longevity.

“I could get his by a bus tomorrow,” they’d say.

That’s true. But you probably won’t.

The fact is, the decisions we make every day have a tremendous impact on how long we live… and how well we live.

For decades, mainstream medicine has told us to focus on diet and exercise if we want to age well and add years to our lives.

That’s not bad advice… but it’s dangerously incomplete.

The truth is, there’s one factor that influences longevity even more than diet and exercise… and nobody is really talking about it.

And learning how to manage it could be the key to giving yourself the long life you deserve.

Researchers from the Oregon Health & Science University recently crunched through six years of data on lifestyle factors and how long people lived.

I’d say the results were a wake-up call… but it sounds like waking people up is the last thing we want to do.

It turns out that sleep was a greater predictor of how long you’ll live than diet or exercise.

People who slept less than seven hours a night had greater levels of mortality. And the only thing worse than poor sleep was smoking.

Now, the researchers said they were surprised… but not me. I’ve been talking about this for years.

Sleep is your body’s nightly repair process. And when you’re not sleeping well, your body doesn’t heal itself properly… and you begin to wear down.

In fact, poor sleep has been linked to diabetes, Alzheimer’s, cancer, and plenty more diseases of aging.

Now, the secret to great sleep is to focus on the health of your circadian rhythm – your body’s natural sleep/wake cycle. Here are some easy ways to get started:

Step 1: Get sun exposure in your eyes first thing every morning. No contact lenses or glasses. You don’t have to look directly into the sun – just keep it in your peripheral vision. This helps set your circadian rhythm for the day.

Step 2: Avoid artificial blue light from technology screens, like TVs, laptops, cell phones, or tablets, at least 60-90 minutes before bedtime. Your body mistakes this light for sunlight, which suppresses the melatonin you need to sleep.

Step 3: Keep a consistent bedtime, even on the weekends.

Start following these steps, and you’ll start sleeping better. And, hopefully, you’ll be on your way to living longer, too.
