The potential connection between sleep and cancer
According to Dr. Dinesh Singh, Chairman Radiation Oncology at Andromeda Cancer Hospital, Sonipat, Chronic sleep deprivation may disrupt circadian rhythms, which regulate the sleep-wake cycle and various biological processes. This disruption can lead to hormonal imbalances, impaired immune function, and increased inflammation—all of which are potential contributors to cancer development.
Less than six hours of sleep per night may put middle-aged adults with high blood pressure, Type 2 diabetes, heart disease, or stroke at risk for cancer and early mortality, according to study published online in the Journal of the American Heart Association.
Cancers that may be linked to sleep deprivation
Breast Cancer: Studies have shown that women with irregular sleep patterns or who work night shifts may have a higher risk, likely due to reduced melatonin levels.
Colorectal Cancer: Research indicates that short sleep duration may be linked to a higher risk, possibly due to increased inflammation and immune system impairment.
Prostate Cancer: Men with chronic sleep deprivation may face a higher risk, potentially related to disrupted circadian rhythms and melatonin reduction.
Lung Cancer: Emerging evidence suggests that poor sleep quality and chronic deprivation may be linked to an increased risk, attributed to immune system effects.
Lymphoma: Some evidence indicates that sleep loss may increase the risk, likely through immune system impairment.
Liver Cancer: Chronic sleep disruption has been associated with a higher risk, potentially impacting liver function and metabolic health.
Sleep is a balance between body and mind. Sleep is required to rest the body and mind. if a person is spiritually balanced and his mind is calm and peaceful then his sleep requirement reduces as in case of persons following yogic principles. For some people a sleep of just 4 hours in 24 hours is sufficient and keeps them energetic throughout the day and night.
Recommendations for Healthy Sleep
To potentially mitigate cancer risk, it is important to prioritize healthy sleep habits:
Maintain a regular sleep schedule.
Create a dark, quiet, and cool sleep environment.
Limit screen exposure before bed.
Practice relaxation techniques.
Moderate caffeine and alcohol intake, especially before bedtime avoid non vegetarian food.
Take dinner at least 4 hours before going to bed. Your stomach should be empty when you go to sleep.
While more research is needed, existing evidence from international studies suggests that chronic lack of sleep may indeed increase cancer risk. It is crucial to prioritize adequate sleep as part of a comprehensive cancer prevention strategy.
