People all care about sleep.

It feels good to be well-rested, recharged and mentally alert after a good night’s rest…

…but did you know that not getting enough sleep can hurt both your long-term physical and mental health?

According to WebMD, chronic sleep deprivation can lead to:

  • Weight gain,
  • High blood pressure,
  • Depression,
  • Stroke, and even
  • Heart attack and heart failure.

Are you consistently getting enough good sleep?

If you're like almost three-fourths of American adults, and you answered no, then it's time to take control of your sleep, and time to make changes to improve it.

So to help you out, here is an in-depth article on sleep. It shows you, exactly, what sleep is, why it's so important, and even gives you a powerful, research-backed way to get a better night's rest... every night.


How to Consistently Get Better Sleep

This article is broken down into three sections: 1) What sleep is, 2) Why it's so important, and 3) A research-backed way to a better night's rest.

What is this?

What, Exactly, is Sleep?

Given you'll spend roughly a third of your life asleep, it's incredible how much about sleep is still unknown.

In fact, scientists still aren't sure exactly why we even sleep! To this day, they only have educated guesses and theories.

...But to give you a good working definition of sleep, here's how Harvard defines it:

A state of low physical activity and response to stimuli, along with increased activity in some brain functions and eye movement.

What does that mean in practical terms?

It means your body is the most ‘switched off’ it can be, while specific parts of your mind (particularly those associated with memory) are more ‘switched on’ (even more so than while you’re awake).

Your body doesn't stay in the same 'switched off' state all night... it actually goes through 5 different stages of sleep, collectively known as a sleep cycle:

    1. Stage 1 - Very light sleep, you can be awakened easily.
    2. Stage 2 - Muscles stop moving, brain waves slow down.
    3. Stage 3 - Deep sleep, brain waves slow significantly.
    4. Stage 4 - Deep sleep, brain waves slow significantly.
    1. REM (Rapid Eye Movement) - Breathing and eye movement become rapid, your brain produces more "awake" brain waves than "sleep" brain waves.

Scientists have found that, each night, our bodies go through sleep cycles in a relatively consistent pattern:

What is the above chart showing?

It shows your body's progression through the five stages of sleep, on an average night. You can see that, with 8 hours of sleep, your body typically goes through five full sleep cycles, the amount of time spent in REM getting progressively longer.

The Dramatic Importance of Sleep

Getting enough high-quality sleep has a huge positive impact on your body and mind...

...but to fully understand its benefit, you need to understand what happens if you don't get enough of it:

The Surprisingly Horrible Effects of Bad, Low-Quality Sleep

Bad sleep broadly affects you in two ways: the short term and the long term.

You know what bad sleep in the short term feels like... you're groggy, tired, and often short tempered...

...but here's what else bad sleep does to your body and mind in the short-term:

  1. Kills your sex drive (you'll have a lower libido and less interest in sex) source 1, 2
  2. Dumbs you down (it impairs your cognitive thinking, concentration, problem solving, concentration, and more) source 1, 2
  3. Weakens your immune system source 1, 2, 3

...And if that wasn't bad enough, over the long-term, bad sleep:

  1. Leads to weight gain (due to increased hunger and cravings) source 1, 2, 3
  2. Causes depression source 1, 2, 3
  3. Can lead to serious health issues (including diabetes, stroke, heart disease, and even heart attack) source 1, 2, 3

Terrifying, right?

So now you know the surprisingly horrible effects of bad sleep, take a look now at the opposite side of things:

The Incredibly Powerful Effects of Good, High-Quality Sleep

You know how good it feels to be well-rested... but here's what getting enough natural, deep sleep does for your body and brain:

  1. Keeps you healthy (both in the short and long term) source 1, 2
  2. Improves mood and emotional well-being source 1, 2
  3. Improves brain function and helps keep you alert and focused source 1,2

Now... remember:

Consistently getting a good night's rest is important not only because you get these powerful benefits, but also because you avoid the horrible determinants from above.

Here’s the bottom line:

Getting enough good sleep goes beyond just making you feel well-rested… it strongly affects your health, your well-being, and your mental and physical performance.

A Research-Backed Way to a Better Night's Rest

From drinking less caffeine, to purchasing black-out blinds, there are a handful of ways to improve your quality of sleep. but in researching all of these different ways, one was backed by the most research source 1, 2, 3, 4, 5, 6and was, by far, the easiest:

Get a better mattress.

Of the adults that actually do get enough sleep, 47% report that they have a comfortable, high-quality mattress. source

Low-quality, uncomfortable mattresses have been found to cause sleep discomfort and pain... source 1, 2

...while good, high-quality mattresses have been found to reduce sleep discomfort and pain source 1, 2, 3and improve overall sleep quality. source 1, 2, 3, 4And this makes sense, right?

If your feet hurt while you're running, you get better running shoes... if you're having trouble sleeping or getting quality sleep, you get a better mattress.
