Sleep deprivation can be caused by many things. If you suffer from sleep deprivation you are physically putting yourself in danger along with risking your health. To solve your physical problem you need to understand what is happening. For many people this requires a real look at their lifestyle and their health.
What is causing your sleep deprivation? Here are a few situations that may be the cause:
Emotional stress and excitement – If you are under stress or overly excited this can be a cause.
Medications – If you are taking a new medication for your medical condition and it is keeping you awake consult your physician.
Caffeine – If you eat foods high in caffeine, a natural stimulant, this can be another cause.
While these are the most common causes there are some sleep disorders which can also be the cause.
Insomnia, nightmares and excessive snoring can be additional causes for sleep deprivation. You may not be able to breathe properly while sleeping. This is called sleep apnea, a very serious condition that causes you to wake up to clear your throat so you can breathe. You may not remember wakening up but you will feel tired.
Taking too many sleeping pills can interact with this condition. Sleep deprivation is a condition that can improve and be overcome with treatment. It is also a condition that can cause health risks later on.

I think this whole debate goes back to the old chicken and the egg dilemma. For example, am I under a lot of stress because my insomnia impairs my ability to concentrate or am I suffering from insomnia because I am under a lot of stress? While the answers to questions like this may never prove entirely accurate, I think a healthy lifestyle consisting of healthy diet, a regular sleep-wake cycle and at least 3-4 days of exercise per week can be the answer to many people’s problems.
