Tigers DO live in the 'jungle', so are harder to find. In the wild, the two do not meet, so there was always a question as to who was the stronger. The lion LOOKED bigger, so was assumed to be stronger, but lions and tigers have different muscle structure, since lions run more in life, and tigers climb more.
Sleep Hygiene The most common cause of insomnia is a change in your daily routine. For example, traveling, change in work hours, disruption of other behaviors (eating, exercise, leisure, etc.), and relationship conflicts can all cause sleep problems. Paying attention to good sleep hygiene is the most important thing you can do to maintain good sleep.
Just like you wash your face and brush your teeth before bed, sleep hygiene is an umbrella term that covers all the things you do leading up to sleep that help or hinder restful sleep. Good sleep hygiene involves getting your body ready for a good night's sleep and not overstimulating it.
