Many People believe that 6-7 hours of sleep is enough, but new research suggests 8 hours of sleep can be critical for a healthy mind, body, and productivity.
The High Cost of Missing Sleep
Skipping adequate sleep doesn’t just make you groggy—it harms your physical and mental health over time. Research published in Progress in Cardiovascular Diseases links chronic sleep deprivation to seven of the top fifteen causes of death, including heart disease, diabetes, and stroke. If you regularly sleep less than 8 hours, you are increasing your risk.
The American Heart Association notes that adults sleeping six hours or fewer face higher rates of high blood pressure, obesity, and cognitive decline. Without enough shut-eye, your body doesn't get its nightly detox and repair time.
What Happens When You Get Less Than 8 Hours
-
Weakened immune system: Poor sleep impairs your body's ability to fight infections.
-
Memory and focus issues: Studies show that sleep deprivation disrupts attention and memory consolidation.
-
Mood changes: Irritability, anxiety, and even depression often follow inadequate sleep.
-
Long-term health threats: Chronic lack of sleep compounds risk for serious conditions like heart disease and type 2 diabetes.
Good Sleep vs Short Sleep
Aim for 7–9 hours per night. Many studies have suggested that people who sleep under 8 hours are more likely to develop hypertension. In contrast, individuals meeting the 8-hour goal showed better stress regulation, cognition, and metabolic health.
How to Finally Get 8 Hours

Stick to a sleep schedule. Go to bed and wake up at the same time daily, even on weekends.

Wind down early. Dim lights and avoid screens an hour before bed.
