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.
Unhealthy lifestyles and sleep habits can create insomnia on their own (without any underlying psychiatric or medical problem), or they can make insomnia caused by another problem worse. Examples of how specific lifestyles and sleep habits can lead to insomnia are: 1  You work at home in the evenings. 2  You take naps (even if they are short) in the afternoon. 3  You sometimes sleep in later to make up for lost sleep.  You are a shift worker (meaning that you work irregular hours).
