Can Lack Of Sleep Cause Cancer In Youngsters? Know Easy Ways To Get Enough
A decline in sleep quality and duration among the general population causes havoc in your body
Several studies and experts have warned against high incidences of certain cancers among the younger population. While most of these are attributed to lifestyle and diet changes, your sleeping patterns weigh heavily on them. According to preliminary research, a decline in sleep quality and duration among the general population causes havoc in your body.
Doctors say lack of sleep is detrimental to the body, and regular sleep is essential to fight infection, maintain cognitive health, and lower blood pressure. Even though existing research is relatively limited and inconclusive, the role of sleep in cancer development needs further research. Here's what we know so far.
How does lack of sleep can cause cancer?
According to studies, shorter sleep - especially less than 6-7 hours every night, can increase the risk of developing colon polyps, which can turn into colon cancer. Also, statistics show that colorectal cancer in patients with sleep disorders is significantly higher, and particularly pronounced among those with sleep disorders and depression.
Doctors say chronic sleep deprivation disrupts circadian rhythm which regulates the sleep-wake cycle and many other biological processes. The disruption causes hormonal imbalances, impaired immune function, and increased inflammation – all of which are markers for cancer development.
Cancers that are linked to unregulated, deprived sleep
Breast cancer
Women who work odd hours or have irregular sleep patterns are prone to breast cancer due to reduced levels of melatonin – a hormone that regulates night and day cycles or sleep-wake cycles.
Prostate cancer
Men with chronic sleep deprivation and insomnia have overexposure to light while working overnight shifts for several years. It significantly reduces the levels of melatonin, encouraging cancer to grow.
Lymphoma
Doctors say sleep loss increases the risk of lymphoma - likely through immune system impairment.
Liver cancer
Chronic sleep disruption and insomnia have been associated with a higher risk, potentially impacting liver function and metabolic health, also leading to liver cancer.
Lung cancer
Poor sleep quality and disruptions also increase the chances of lung cancer due to impairment of the immune system.
Other health issues related to lack of sleep
According to various studies, there are a wide range of health problems that can be caused due to less sleep, apart from cancer. The Centers for Disease Control and Prevention say one in three people report that they get less than the recommended seven-plus hours of sleep per night, across the world, and the figures are alarming.
Sleeplessness is also linked to many other chronic illnesses - including heart disease, obesity, diabetes, and depression.
Ways to regulate sleep
The CDC recommends adults get 8-9 hours of uninterrupted and regulated sleep every night. However, quality of sleep is just as important as quantity and a good night’s sleep involves few sleep-wake disturbances. However, the key to long, quality sleep, is making disciplined choices before going to bed, which include:
- Sticking to a consistent sleep schedule
- Exercising regularly
- Avoiding caffeine, nicotine, and alcohol at least 3-4 hours before bedtime
- Reducing your screen time
- Keeping your bedroom cool and at a comfortable temperature
- Reading before sleeping
- Taking doctors’ prescribed melatonin supplements
