Right Sleep Time Recommended by Doctors: How Much Sleep Is Healthy for You?
Getting the right sleep time recommended by doctors is essential for overall health and long-term wellbeing. Many people think sleeping more automatically means better health, but medical experts warn that both too little and too much sleep can increase serious health risks.
According to American heart surgeon Dr Jeremy London, sleep deprivation affects far more than just your mood. Ignoring your body’s natural sleep cycle can disrupt hormones, strain your heart and raise the risk of chronic diseases. Here’s what doctors recommend.
How Many Hours of Sleep Is Ideal?
Sleep duration and health follow what experts describe as a “U-shaped curve.” This means both extremes are harmful.
For most healthy adults, aiming for 7–8 hours of consistent sleep each night offers the best balance for recovery and overall functioning.
Why Your Biological Clock Should Not Be Ignored
The human body runs on a natural internal system called the circadian rhythm , which is closely linked to daylight and darkness. When you sleep and wake in alignment with natural light, your hormones function properly and your body repairs itself efficiently.
However, staying awake late into the night or maintaining irregular sleep patterns disrupts this rhythm. Over time, this can disturb your body’s internal chemistry, leading to fatigue, mood changes and higher stress levels.
Humans are not designed to function as nocturnal beings. Consistently going against your biological clock places unnecessary strain on your body.
How Poor Sleep Affects Hormones and Appetite
Sleep plays a critical role in regulating hormones that control hunger, stress and emotional stability. When sleep is disturbed:
These disruptions can gradually contribute to weight gain and metabolic issues.
Long-Term Health Risks of Chronic Sleep Problems

Doctors emphasise that getting at least six hours of consistent sleep is crucial for maintaining heart health. Over time, poor sleep patterns can significantly raise cardiovascular risk.
The right sleep time recommended by doctors is not about extremes. Sleeping too little or too much can both negatively impact your health. For most adults, maintaining a steady routine of 7–8 hours of quality sleep aligned with natural daylight is the safest and healthiest approach. Prioritising sleep today can protect your heart, hormones and overall wellbeing in the years ahead.

Sleep plays a critical role in regulating hormones that control hunger, stress and emotional stability. When sleep is disturbed:
- Appetite-regulating hormones become imbalanced.
- Stress hormones increase.
- Cravings and mood swings become more frequent.

- Heart disease
- High blood pressure
- Certain cancers
