When it comes to training, all the movements you make during your workout are important. What you do outside the gym - what you eat and your sleep pattern - are crucial.
Time to recover
During sleep, your body has time to recover. This mainly involves repairing the muscles you used during your workout, but also rebuilding energy. When you have good sleep quality, your body produces growth hormones. This is essential for muscle development. For an adult, it is recommended to sleep 7 to 9 hours a day for optimal recovery.
Training also contributes to your sleep quality because it has a chemical effect on your brain. More specifically: adenosine. This substance makes you feel sleepy and helps you fall asleep faster. So it's a win-win situation: if you exercise regularly, you have better sleep quality. And with better sleep quality, your body recovers better.
Is that all?
Absolutely not. A good night's sleep allows you to perform better physically and mentally, and the gym is no exception. In general, you can focus better and are in a better mood. This improves your performance both inside and outside the gym.
Conclusion
A good sleep pattern is very important for your workout routines, and exercise is very important for a good night's sleep. Sleep and exercise complement each other perfectly; this is simply how the human body works.
