How to Build & Grow Muscle in Your Sleep

Maybe you're training for a marathon, a professional athlete, or you want to look better in a swimsuit!

It's been proven that a regular exercise, strength training, and a balanced diet are critical to a successful athlete. But did you know that sleep helps build muscles?

Sleep is critical for your want to get fit and build muscle.

When we're asleep, our body gets the required time to restore itself, giving us the energy to take on the day. Sleep can help develop muscles and help them recover properly, grow, and prevent illness. Sleep has plenty of benefits for elite athletes and everyone who is active.

How Muscles Grow

Let's take a look at the science behind muscle growth. Muscles grow through a process of hypertrophy. It's also explained as the enlargement of an organ or tissue from the increase in the size of its cells. For hypertrophy, must first be activated or stimulated.

This muscle growth happens when cells experience damage due to physical exertion. Exercise, whether running, lifting weights, or any other physical activity that puts your muscle cells under stress, activates your body to repair the damaged cells with growth hormone and protein synthesis. [1] These cause each damaged cell to become more significant to handle the physical demand.

Did You Know: Muscle hypertrophy happens when cells work to restore muscle fibers.

Deep Sleep and Muscle Growth

Muscle repair and development occur during deep sleep (REM sleep) due to the natural release of growth hormones. Studies show that humans release 70% of the hormone during deep sleep. The more deep sleep you get, the more you produce. [2]

How Important is Sleep and Muscle Growth?

The math is straightforward. If more deep sleep equals more growth hormone, and more growth hormone equals bigger muscles, then more deep sleep equals bigger muscles!

Numerous studies indicate that optimized deep sleep improves physical performance by as much as 9% and enhances muscle recovery by as much as 30%. [3]

How to Increase Sleep for Muscle Growth

Deep sleep is optimized when we sleep cold. Additionally, our bodies release more hormones when core temperatures are lowered.

Conversely, another study found any significant rises in core temperature resulted in complete inhibition of growth hormone release. [5]

Thus, not only does sleeping cold promotes muscle growth, but your tendency to “sleep hot” may work against you and your goals by interfering with building muscle.

Get Enough Sleep

Whether you're a professional athlete or looking to get in shape, getting anywhere between seven to nine hours of sleep each night is suggested. Sleep quality in athletes is associated with improving competitive success and overall performance.

Get More Deep Sleep

According to New Health Advisor, it can be difficult to wake you up in this sleep stage, and it's typical to feel disoriented for the first few minutes after waking up.

So, how many hours of deep sleep is recommended?

For individuals over 18 years old, it's recommended 1.5-1.8 hours of deep sleep—but you can't have too much!

Deep sleep repairs and restores your body for the next day. But why is this repair function so important? You can read our blog and learn more about how to increase deep sleep and its importance.

Create a Sleep Routine

Our bodies run on circadian rhythms, like internal clocks regulating mental and physical changes occurring in our bodies each day.

Similar to when you get hungry at the same time each day - right around lunchtime. Similarly, if you keep a consistent bedtime schedule, your body will start transmitting cues every night simultaneously, putting you into a deeper, more restorative sleep.

This isn't just for weekdays! It also means trying to keep the same sleep schedule for the weekends. Staying up on the weekends can alter your rhythms, making it harder to fall asleep during the week.

Good Sleep Hygiene

Practicing good hygiene is crucial for optimizing muscle growth and sleep recovery. This includes limiting the amount of electronic device usage leading up to bedtime. If possible, do the following:

• Turn off electronics 30–60 minutes before bed, helping limit blue light.
• Keeping your bedroom temperature cool.
• Block out unnecessary light that can affect your sleep.
• Use a white noise machine to help block out unwanted noise.

Relax with Yoga

We all know that yoga is good for you and offers plenty of benefits. But between cardio and strength training, it can be hard to find time for it. However, practicing a few poses before bed can improve sleep quality. Recent research has shown that practicing yoga improves sleep and can decrease levels of the stress hormone cortisol.

Nutrition Building muscle requires good sleep, but nutrition plays a crucial role. Similar to creating a sleep routine, it's essential to maintain healthy eating habits as it can encourage healthy sleeping patterns. Eating a high-fiber diet with fresh vegetables, fruits, low-fat proteins (chicken & fish), and whole grains can help build muscle.

We all enjoy cookies, ice cream, and other sweets. But try to limit your intake or avoid consuming foods high in sugar when possible. Next time you're at the grocery store, search for foods high in B vitamins; B vitamins are thought to help regulate melatonin.

Sleep Cooler at Night

There are ways to ensure you sleep cold (no, they do not require cryogenic freezing)!

• Sleep with the thermostat set between 60-67.
• Make sure your bedding (sheets & pillowcases) is made from breathable cotton.
• Avoid synthetic fabrics like polyester for your bedding. They are more tightly woven and trap body heat. Also, foam mattresses can also trap heat.
• Wear breathable clothes when sleeping. Pajamas made from Bamboo naturally cool the skin.
• Use a bed cooling system such as the Chilipad Dock Pro or Chilipad Cube. They are 100% natural, fit on any bed, and allow you to control your bed temperature ranging from 55º to 115º F.
