Get the most out of your rest and recovery by understanding the science behind sleep, sleep cycles, and how to improve your sleep quality and quantity.


Many people don't understand the importance of getting a good night's sleep. Yet, without adequate sleep, it's difficult to function on a daily basis.

In fact, getting a good night's sleep has been linked to many health benefits including:

Better mood and mental health

Increased productivity

Lower stress and anxiety levels

A healthier immune system

Improved physical fitness

Better sex drive

Decreased risk of cardiovascular disease and stroke

Here's a basic formula that should help you figure out how much sleep you need to achieve optimal results:

Number of hours of sleep = ((14 - age) * 0.8) + 6.4

That would translate into 10.2 hours for a 14 year old, and 7.8 hours for an 80 year old. Keep in mind that this is an approximation of a healthy sleep pattern. A number of factors influence sleep quality, and your requirements may vary based on the following:

Your age

Your gender

Your genetics

How much noise you're exposed to

Whether or not you exercise regularly

Whether you smoke or drink alcohol

Your occupation and environment

Whether or not you have a partner

However, this basic formula should help you estimate what you need.

The Science of Sleep: Understanding the Importance of Rest and Recovery

Understanding the Importance of Rest and Recovery:

Getting good quality sleep is important for both your mental and physical health.

According to the American Academy of Sleep Medicine, poor sleep quality is common among Americans, and it has been linked to many negative consequences including:

Higher risk of diabetes

Cardiovascular problems

Depression and anxiety

Weight gain

Stress-related illnesses

Problems with concentration and memory

High blood pressure

Insomnia affects as much as one third of the U.S. population.

Despite the proven importance of sleep, many people don't get enough of it. According to the National Institutes of Health, only 55% of adults report sleeping more than seven hours a night. That's compared to 76% of teenagers who get more than nine hours of sleep a night.

As much as we think we know about sleep, much of it remains a mystery. For example, how much sleep does a baby really need? And why is it so important to get good quality sleep every night?
