The influence of food in sleep
Food can have decisive influences on sleep. Besides light and temperature, food is the third determining factor in the influence of biological rhythms. Through food, we can control the biological rhythmicity and quality of sleep.
In Traditional Chinese Medicine, there is a very interesting phrase about food: “raw food in the morning is gold, in the evening it is silver, and at night it kills”. One of the meanings of this sentence is the change of central temperature curve. When we eat raw food at night, our digestive system needs to increase the local metabolism to do the digestion. This raises the central temperature by changing all sleep behavior. Therefore, salads, fruits, raw fish, carpaccio and other raw foods are actually harmful to sleep by unbalancing the central temperature.
Another problem is that according to Traditional Chinese Medicine, when there is an increase in the central temperature, there is a decrease in peripheral temperature in the same proportion. That is, some organs that are distant from the digestive system organs suffer from a decrease in temperature in their arteries, especially the heart and the brain. According to the tradition, the risk this entails is that as we cool the arteries in those organs, the cold ends hardening fatty molecules present in the wall of the arteries in medium to long term.
The opposite is true. When the temperature of the digestive system organs falls, the peripheral temperature in the arteries increases. In the view of this medicine, heat helps the “softening” of fats that may form on the wall arteries, reducing the risk of problems related to this kind of tissue. Therefore, knowing the best time to eat could be the key for good health.
