The Truth behind Insomnia and Snoring as a Risk Factor for Cancer

There are many factors that are related or considered as risk factor of cancer. Insomnia and snoring are two of such factors that are assumed as risk factor of cancer. Read through the discussion to learn more about this fact.


Are you unable to sleep well? Do you usually sleep late at night? Have you had several sleepless nights? Are you insomniac?

Many sleep-related researches have linked insomnia as a risk factor for cancer. What is the truth behind it?

Insomnia as risk factor for cancer

Generally, sleep is our body’s resting period; it gives you the opportunity to recharge and re-boost after a long day of work and activity. Like how it enhances every bodily system, sleep improves your immune function too! This explains how we become susceptible to infections when we lack sleep. But how about getting cancer? It has been further proven that sleeping supports the activity of particular immune system helpers that safeguards the body from developing cancerous tumours. Tumour necrosis factor, one of the body’s cancer front liners, increases ten times when you are sleeping. In contrast, inadequate sleep would lead to a significant decrease of your body’s natural killer cells and a compromised immune functioning.

More than its effect on your immune system resistance, sleeplessness also affects hormone release. Melatonin, your sleep-inducing hormones, is produced with a lesser exposure to light. Its release triggers a decrease in oestrogen production. If you stay up late at night and get yourself exposed to more light, melatonin would be reduced while oestrogen is released. Unfortunately, too much of the latter can stimulate breast cancer growth. To provide further truth on this, a cancer research was done that aimed to compare the number of cases between blind and sighted women. The result- 5 blind women out of 10 well-sighted women get breast cancer. Lesser prevalence is also noted for other cancer cases.

Insomnia as a risk factor for cancer- is this a fact or a coincidence? While various researches have proven this true, still this fact cannot be absolute. Cancer is a multi-factorial disease and having unhealthy sleep might just play one life-changing role.


Snoring is a sleeping disorder type wherein your body doesn’t get enough oxygenation while one is asleep. According to sleep experts, having low blood oxygen level can stimulate the development of cancerous cells as it boosts the vessel growth that nourishes them.

Other than snoring, other usual kind of sleep disorder is sleep apnea which signs include snoring. It is one of the most common types of sleep disorder. This sleeping disorder hinders the airway; oftentimes the tongue collapses towards the airway during the breathing cycle which leaves the person struggling to catch up his breath.

As what US researchers have observed in 1,500 individuals and beyond, people who have severe form of sleep disorder breathing will likely have more chances of developing cancer than those who don’t have. People who have moderate sleeping disorder have doubled the chance of developing cancer, while those who have slight sleeping disorder, have 10% chance for getting cancer.
