Milk (and its fermented form) is a food promoting sleep per studies mentioned below. "However, consuming milk as such is unlikely to induce sleep, as the amount of tryptophan present in milk is too small. Milk coupled with a carbohydrate food at bedtime can be a potential sleep aid." Also "having a glass of warm milk is unlikely to raise skin temperature enough to have any effect" on sleep.
- Per a study 'Association between difficulty initiating sleep in older adults and the combination of leisure-time physical activity and consumption of milk and milk products: a cross-sectional study.' by Kitano N et.al. in 2014, dairy consumption may effectively improve problems with falling asleep.
Our findings suggest that the combination of engaging in LTPA and consuming milk or cheese is necessary as a prescription to improve falling asleep for older adults suffering from DIS. Additionally, engaging in LTPA along with dairy consumption may effectively improve a problem with falling asleep.
- Per a study 'The effect of Lactobacillus helveticus fermented milk on sleep and health perception in elderly subjects' by Yamamura S et.al. in 2009, there was significant improvement in sleep efficiency and number of wakening episodes in actigraph data after intake of fermented milk, whereas no significant changes were observed for the placebo.
CONCLUSION: This short-term (3-week) intervention study indicates that Lactobacillus helveticus fermented milk may have a more favorable effect on improving sleep in healthy elderly people as compared with placebo.
- Per a study 'Strategies of Functional Foods Promote Sleep in Human Being' by Yawen Zeng et.al. in 2014, milk is a functional food promoting sleep in humans.
Foods rich in sugar, caffeine, green tea, etc can contribute to insomnia. The factors promoting sleep in human being are the functional foods include barley grass powder, whole grains, maca, panax, Lingzhi, asparagus powder, lettuce, cherry, kiwifruits, walnut, schisandra wine, and milk.
