What is sleep deprivation? Sleep deprivation is when the body feels tired and sleepy, usually while sleeping. People who are sleep deprived are also at risk for serious health conditions like sleep apnea. Do I sleep better on a regular basis? This is something I have seen people ask me, but I would never really tell someone that. Most people don't really want to know, and in my opinion it makes no difference. Most people don't care if you are having more or less sleep. How long can I sleep without being tired? Sleep should be adequate for every day of the week. If you sleep just 5-6 hours, your body will adjust and get used to it. But if you sleep for an average of 15 hours a day you will still be fine. Is there any effect of light? Some people think that the lack of light will make you tired. That is wrong. No amount of light has any effect on sleep. What if I have a problem with my light switch? If your light switch doesn't work correctly, the only thing you can do is try to sleep with your lights on. Can you recommend me a good place to sleep for a good night's sleep? Sure! The Sleep Center in Santa Monica, California has a big selection of comfortable beds.
