Even if garlic’s odor works wonders, it may be repelling for some. Another way to proceed is by eating it before bed or using it to prepare baked garlic bread. (Note that the smell may be repelling for people around you, so make sure to always wash your mouth. You can also use Miswak sticks) Not many publications took interest in studying the link between garlic clove and bettering your sleep, but in the case of asthma patients, it brings relief to drink a mixture of milk and boiled cloves before sleeping.
Additionally, garlic contains a number of useful minerals, specifically zinc, calcium, phosphorus, iron, magnesium and potassium. The last two are known to play a key role in supporting deep sleep. This is explained by the fact that magnesium helps in maintaining healthy levels of GABA, which is a neurotransmitter that increases relaxation and thus promotes sleep.
