Health Problems due to lack of sleep  

Many times, we brush aside a full night's sleep due to our busy schedules, a need for "down time" that keeps us up, or simply life's circumstances. But a lack of sleep can result in more than just feeling tired (which is bad enough). Medical experts warn that chronic sleep deprivation can have serious effects on your health.  


Here are some health problems that may result from lack of sleep.  



While not all cancer risks are affected by lack of sleep, studies have indicated that breast and colon cancer risk is greatest for those who work night shifts. Apparently, the exposure to light in the night-time hours reduces the body's production of melatonin. Melatonin is a brain chemical that helps promote healthy sleep, but it may also reduce tumours and protect against cancer as well. The less you sleep, the less melatonin your body manufactures.  


Heart Attacks 

Statistically, heart attacks occur more often in the early morning hours. Experts believe this may have something to do with the particular way that sleep and waking affect the cardiovascular system. Studies have shown that the health problems that often lead to heart disease - obesity, high blood pressure, etc. - are exacerbated by lack of sleep.   


The cardiovascular system, which is believed to go into a more relaxed state during sleep, can be taxed during prolonged period without sleep. In some cases, three days without sleep can lead to a heart attack or heart failure. Blood pressure has also been known to go up due to lack of sleep, with some cases being reported where the pressure actually doubled. 


Unhealthy Relationships 

When you don't get enough sleep, you tend to be moody and irritable, which is not good for any relationship. Also, sleep problems may lead to partners sleeping separately, or resentment on the part of one or both of the partners for the problem. This kind of tension may affect any children in the family as well.  


Impaired Cognition 

An inability to think straight or think constructively is a problem associated with sleep deprivation. You may have trouble remembering things, too, if you are not getting enough sleep. There is a noticeable drop in alertness and cognitive ability, which can sometimes appear to be cumulative if the lack of sleep is prolonged. Sensory information can sometimes be processed slower than normal. 



From automobile accidents to accidents on the job, sleep deprivation has been implicated in all sorts of accidental injury situations. The brain just does not react as quickly or efficiently when you are starved of sleep, and clumsiness and mistakes are also symptoms associated with lack of sleep (and accidents).  


Psychiatric Conditions 

Psychiatric conditions are among the potential consequences of not getting enough sleep, with conditions such as depression and anxiety often being used as examples. 


Other Issues 

The ability to control body temperature is also disrupted, with some people losing the ability to regulate body heat altogether after prolonged periods with disrupted or broken sleep cycles. Significant lack of sleep has also been known to speed up the aging process of the skin, making a person seem older than they actually are. 


The immune system can also be impaired by a lack of sleep, making a person more susceptible to infection and disease.
