Bedtime Mistake DOUBLES Death Risk (Don’t Do This…)

The older you get, the more serious you become about your sleep.

In the old days, maybe you could stay up to all hours… and get by with just a few hours of sleep.

Now, you’re making sure you get good shuteye every night.

And that’s a smart idea.

Sleep is your body’s nightly repair process, and our bodies depend on it to keep us healthy.

But there’s one mistake countless Americans are making at bedtime each night… and it could have serious consequences for your health.

It can send your immune system haywire – and even double your risk of an early death.

But I’ll show you how to get the problem of under control – and how to enjoy the best sleep of your life.

Starting tonight.

Maybe you sleep with a nightlight or small lamp on… or even the TV running in the background.

Or maybe the light from outdoor streetlights gets into your room easily.

Either way, if your room is not pitch black at night, you could be sabotaging your own health.

In a new study on mice, Israeli researchers found that light disturbances at night interfered directly with antibody production and immune system function.

That’s a big problem for seniors in particular, because our immune systems already weaken with age.

And this isn’t just about fighting off colds or infections more easily. An impaired immune system can be a direct threat to your life, especially as you get older.

In fact, researchers found that mice exposed to nighttime light had a 2.35-times higher risk of death than animals kept under natural light-dark cycles.

Nighttime light can disrupt your body’s circadian rhythm – which actually plays an essential role in how well your immune system functions and when antibodies are produced and released.

Now, honestly, this is my favorite type of health problem – because the fix is simple.

You need to keep your bedroom pitch black at night, while you’re sleeping. No lamps, nightlights, or other sources of light.

If you’re worried about tripping or other safety issues if you have to get up at night, just keep a flashlight by your bed.

And if there’s too much exterior lighting getting into your bedroom at night, invest in blackout curtains.

Keeping your room dark at night will help you sleep much better – and will give your immune system the support it needs to do its job.
