By , By Christie Griffin, Fitness Magazine
Yes, we at FITNESS love a great early-morning workout. But we also know about the importance of a good night's sleep, and not just because sleep deprivation is tied to weight gain. Here, the most interesting health facts that warn against burning the candle at both ends. Pace yourself, people.
 
1. Flu-Z's

If you're sleep-deprived before getting your flu shot, it can take three to four weeks for the vaccine to kick in. Those who don't get appropriate rest have a weaker immune system, which hinders the vaccination's effectiveness.


2. Take This to Heart

Poor sleep is more dangerous to women than to men. Women experience higher risks of cardiovascular problems when they don't get enough rest and they're also more susceptible to psychological distress, depression, and anger. Source: Duke Medicine

 

3. Big-C Shifts

There's a link between those who work night shifts and breast cancer; researchers say they think it's because melatonin is suppressed, which is necessary for protection against some cancers. "Shift work that involves circadian disruption" is officially listed as a probable carcinogen. Source: World Health Organization's International Agency for Research on Cancer
