There is absolutely no evidence to support this claim and there is actually evidence against it, when you consider the billions of dollars the pharmaceutical industry has spent trying to find this evidence. If there was an imbalance to blame, they would probably have found it by now and you would be hearing about it on TV.
Sleep needs vary widely among individuals, and there is no “Gold Standard” that everyone should aim for. Just as we all have different shoe sizes, we all need different amounts of sleep. You wouldn’t expect someone 5 feet tall to have a size 9 shoe would you? Nor would you try to force someone 7 feet tall to wear a size 9 shoe.
The harder you try to control sleep, the less likely you will fall asleep; it is much easier to force wakefulness than to sleep at will. It is like trying to force yourself to sweat or digest faster. We have limited control over these body functions.
Nighttime sleep is not independent of daytime activities, thoughts and feelings; therefore, you must carefully examine these relationships in order to make your sleep more predictable and develop more self-control
In truth, exactly the opposite is true. Most studies show that people who take sleep medications are MORE likely to have difficulty functioning the next day than those who don’t, because of residual side-effects of the medication (e.g., groggy)
As long as you don’t sleep in or nap the day after a bad nights sleep, your sleep the next and subsequent nights should be better not worse. However, if you start to worry and anticipate a bad night or week, this can often become a self-fulfilling prophecy. How has your sleep been the last few weeks when you have been keeping a regular schedule regardless of how you slept at night?
