The lavender fragrance can be used for two things – to keep you focused during the day and to keep you free from insomnia during the night. The oil directly plays on your endocrine system and calms your stress down. You will be able to have a peaceful sleep because of this. If you are not so happy with the lavender fragrance, you can try the fragrance of rose or even that of vanilla.
These are the simplest hacks that are proven to grant a great sleep. Try them and you will be free of your sleep deprivation issues for life.
