Would love to hear from other folks who've sailed there during that time of year and what the weather was like. Thank you! Jul 30, 2015.
Insomnia is a condition that does not let a person sleep properly at night. Researches show that those people with vitamin D deficiency have more chances of having insomnia than others. Therefore, vitamin D deficiency can be called as a big cause of such sleep disorders. So, if you start consuming required amount of vitamin D regularly, then you may have high chances to cure it.
Sleep deficiency is a broader concept. It occurs if you have one or more of the following: 1  You don't get enough sleep (sleep deprivation)  You sleep at the wrong time of day (that is, you're out of sync with your body's natural clock)
