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.
Inadequate Sleep Hygiene. Inadequate sleep hygiene is a sleep disorder primarily caused by bad sleeping habits. It is often corrected by making a few simple changes to your routine and daily practices leading up to your bedtime. If not looked after in this way though, inadequate sleep hygiene can lead to, or continue to produce side effects common with many other sleeping disorders, which can be harmful to quality of life. The first category is related to falling asleep.
