Consequences of inadequate sleep encompass a range of health issues:
1. Obesity:Reduced sleep links to obesity, impacting hunger hormones Ghrelin and Leptin, leading to increased appetite, slowed metabolism, and insulin resistance.
2. Insulin Resistance and Type 2 Diabetes:
Sleep deprivation elevates fasting insulin levels, comparable to six months of unhealthy eating. Even one night of insufficient sleep disrupts insulin sensitivity and raises fasting glucose levels.
3. Impaired Brain Function:
Insufficient sleep hampers memory, reduces cognitive abilities, and accelerates Alzheimer’s progression by allowing the accumulation of brain plaques.
4. Cardiovascular Disease: Lack of sleep raises blood pressure, increasing the risk of heart disease.
5. Inflammation and Chronic Disease:
Getting less than 7-8 hours of sleep heightens inflammatory markers, associated with cardiovascular disease, high blood pressure, and type 2 diabetes.
6. Mental Illness:
Poor sleep contributes to overreaction, impaired judgement, and heightened risk of depression and suicidal thoughts.
7. Cancer Susceptibility:
Sleep deprivation, suppressing melatonin, is linked to increased vulnerability to cancer development.
8. Pain and Injury:
Inadequate sleep exacerbates chronic pain and raises the risk of injury, especially in teenage athletes sleeping less than 8 hours per night.
