Researchers a Taiwan Taipei Medical University found in a study of 22 women and 2 men that consuming 2 kiwis an hour before bedtime greatly affected sleep patterns. 35.4 % fell asleep faster, 28.9% slept more soundly, 42.4% had improved sleep quality, 5.41% had improved sleep efficiency and 13.4% had better overall sleep.
Research shows that the high antioxidant levels and high serotonin levels were responsible for these amazing results.
Serotonin is a hormone that also functions as a neurotransmitter, and is also involved in a broad range of physiologic processes. It also has digestive and cardiovascular functions, assists in learning and memory, and helps to regulate appetite and mood. Serotonin deficiency is also associated with depression and mood disorders.
Serotonin is also critical in sleep. Its presence helps initiate sleep onset and maintain sleep during the night. It also helps to stimulate wakefulness in the morning. Research indicates that manipulation of serotonin up or down can promote or inhibit sleep. Serotonin appears to interact with melatonin, another essential sleep hormone in helping to regulate the body’s 24 hour circadian cycle as well as other physiologic functions. Studies have also shown that increase in the levels of serotonin any in turn increase the melatonin levels, thereby making for a better night’s sleep.
So, reach for two kiwis before reaching for the pills.
