SLEEP!

Researches gave subjects a hepatitis vaccine and put them into two groups.  One group was allowed to sleep the night after the injection, the other was kept awake with music and television.

Throughout the course of the year, the subjects blood was monitored and guess what…the group that had gotten the sleep created significantly more anti-bodies against the hepatitis virus.  This is exactly the reposes you want from a vaccine.

Researchers believe this may be due to increases in growth hormone and melatonin which can inhibit cortisol production, allowing the immune system to become stronger.
