Substance use disorder occurs when a person needs alcohol or another substance (drug) to function normally. Abruptly stopping the substance leads to withdrawal symptoms. Addiction means that a person has a strong urge to use the substance and cannot stop, even if they want to.
So it is important to maintain positive nitrogen balance in the body while sleeping. When you do and conditions are right so that your rate of protein synthesis exceeds your rate of degradation, and you maintain a positive nitrogen balance, you can grow while you sleep.
But over the long term, a person's growth may be affected by not getting the full amount of sleep. That's because growth hormone is normally released during sleep. If someone consistently gets too little sleep (known as sleep deprivation), growth hormone is suppressed. Lack of sleep also can affect other hormones. Studies show that sleep deprivation is linked to obesity and diabetes.
