Getting a good night's sleep is vital for bodily function and overall health, however, oftentimes drifting to sleep can be difficult.  Here are five drinks that can help you drift off into a peaceful slumber.  Warm milk The essential amino acid tryptophan, naturally found in milk, increases serotonin levels, which are linked to the sleep hormone melatonin. This helps promote sleep and fight insomnia.  Chamomile Tea Chamomile, a member of the Asteraceae family and commonly associated with sleep, has been linked to improved sleep quality by relaxing the nervous system. Valerian Tea This powerful root is known to promote sedation, helping to reduce the time it takes to fall asleep and improving overall sleep quality.
