If you want to fall asleep quickly and easily, do not drink coffee, cola, black or green tea in the afternoon. These drinks contain caffeine which simulates heart and blood circulation. The effect of caffeine can last up to 14 hours.
Before bedtime avoid alcoholic beverages. It is true that drinking beer or wine will make you fall asleep faster but it will disturb your sleep in the second half of the night.
Do not eat late. If you go to sleep with your stomach full, it will have to work at night too which will not allow you to rest. Do not smoke in the evening! Nicotine simulates brain and entire body.
Work out but not until exhaustion. If you are tired your body will need a few hours to get back to normal state and only then you will be able to sleep.
Do not look at the watch if you woke up at night. You will definitely start counting and planning your day. Keep your alarm clock facing the wall. Also do not put the light on if you wake up at night. This will also cause you to awake.
Always wake up at the same time even if its weekend or holidays. This will help you to stabilize sleep rhythm. Make sure the end of your day is calm. Do not have any mental work 2 hours before going to bed.
Long nap is useless because in the evening you will not feel tired and you will find difficulties to fall asleep. If you are unable to fall asleep straight away, go for a walk or simply leave the bedroom and stay in another room for a while. Go back to bed only when you feel sleepy.
