How Lack of Sleep Is Sabotaging Your FITness Journey



I never realized how much sleep contributed to my fitness until I began my first Journey to Ms. Olympia. With 2 workouts a day + a strict nutritional regimen while balancing a career, the effects of lack of sleep started to creep on me quickly. Being lethargic, unable to complete workouts, or too tired to even get up and make it to the gym made me realize that sleep has effects on your body beyond the gym.

Sleep is an essential component of a healthy lifestyle, and it plays a crucial role in our physical and mental well-being. Most of us know that getting enough sleep is important for feeling refreshed and alert during the day. However, the impact of sleep on our everyday life goes beyond just feeling rested. In fact, there are some surprising ways that sleep affects our daily activities. Here are five unbelievable ways that sleep affects your everyday life:


1. Sleep affects your memory


Have you ever had a hard time remembering something after a night of poor sleep? That’s because sleep plays a critical role in memory consolidation. During sleep, your brain processes and stores information that you have learned during the day. Studies have shown that sleep deprivation can impair memory and cognitive performance, making it harder to retain and recall information.

2. Sleep affects your appetite


Do you ever feel hungrier than usual after a bad night's sleep? That’s because sleep deprivation can disrupt the hormones that regulate appetite. When you don’t get enough sleep, your body produces more ghrelin, the hormone that stimulates hunger, and less leptin, the hormone that signals fullness. This can lead to overeating and weight gain over time. Studies have shown that sleep-deprived individuals tend to consume more calories and have a preference for high-calorie, high-fat foods. Additionally, sleep deprivation can lead to an increase in cortisol, a hormone that contributes to fat storage.

Not getting enough sleep can also have a negative impact on our physical fitness. Sleep is crucial for muscle repair and recovery, and a lack of sleep can hinder our body's ability to repair and rebuild muscle tissue. Additionally, sleep deprivation can lead to decreased energy levels and decreased motivation to exercise. This can make it harder to maintain an active lifestyle, which is important for overall physical health.

3. Sleep affects your mood


Have you ever felt more irritable or anxious after a night of poor sleep? Lack of sleep can have a profound impact on your mood and emotional well-being. Sleep deprivation can lead to increased levels of stress hormones like cortisol, which can make you feel more anxious or irritable. On the other hand, getting enough sleep can help you feel more relaxed and emotionally balanced.

4. Sleep affects your immune system


Did you know that sleep plays a crucial role in your immune system? During sleep, your body produces cytokines, which are proteins that help your body fight off infection and inflammation. Sleep deprivation can lower your body’s production of cytokines, making you more susceptible to illness and infection.


5. Sleep affects your performance


Whether you’re an athlete, student, or working professional, getting enough sleep is crucial for optimal performance. Studies have shown that sleep deprivation can impair physical performance, cognitive abilities, and reaction times. In fact, sleep deprivation has been shown to impair performance as much as being under the influence of alcohol!


Sleep is much more than just a period of rest for our bodies. It affects our memory, appetite, mood, immune system, and performance in ways that we may not even realize. So, if you want to be at your best, make sure to prioritize getting enough quality sleep each night. Your body and mind will thank you!
