Changing occur in sleep pattern according to aging process this is called as "sleep architecture" .
Before you rush to the drugstore to buy an over-the-counter
sleep medication, try one of the following natural sleep remedies. Many of these can not only help you fall asleep and stay asleep, but they may also promote muscle relaxation.
Have a banana before heading to bed. These foods contain
tryptophan, an
amino acid that’s used to make serotonin. And serotonin is a brain chemical that helps you sleep.
Carbohydrates help trytophan enter the brain.
Try a glass of warm milk (milk contains tryptophan) and a cookie, or warm milk with a spoonful of honey.
Avoid big meals late in the evening. You need three to four hours to digest a big meal.
wishing you have a good sleep.
