There are many factors that affect how long it takes to fall asleep, including age, sex, stress level and caffeine intake. However, there are some simple techniques that you can use to help you sleep faster. One of the most important things you can do is to avoid caffeine before bedtime. Caffeine is a stimulant and has the ability to keep you awake. If you want to drink coffee or tea before bed, limit yourself to small amounts and wait until after you're sleepy to consume them.
