Getting 8 hours of sleep is important, but sleep quality depends on more than just the number of hours.
Your body works on a 24-hour circadian rhythm, which controls:
• Melatonin (sleep hormone)
• Cortisol (stress hormone)
• Heart function
• Digestion and metabolism
Melatonin usually starts releasing around 9–10 PM and peaks between 12–2 AM, helping your body get deep, restorative sleep. Sleeping too late can disturb this natural cycle.
Irregular sleep timings are linked to a 20–30% higher risk of metabolic issues, including weight gain and poor blood sugar control.
Poor or inconsistent sleep can also reduce how well your body handles sugar by up to 25%, increasing long-term heart risk.
Healthy sleep isn’t just about duration, it’s about timing and consistency.
