According to the Journal of Psychosomatic Research, sleep quality, not quantity, is more related to sleepiness. In other words, even if you do eventually fall asleep, your quality of sleep is what determines how well rested you feel.
In order to get the sleep quality you deserve, you need to modify your sleeping environment.
For example, by blocking 100% of the light from your eyes, your brain begins to produce melatonin. This is the hormone in the brain that is necessary for starting the REM deep rest process.
If you don’t already know, REM sleep is the stage of the sleep cycle that makes us feel well-rested in the morning. Lack of REM sleep is connected to low melatonin levels.
Interestingly, being exposed to light—even dim light—will lower your melatonin levels.
