Nobel Prize in Medicine

When the 2017 Nobel Prize in Medicine was announced, many were surprised—it focused on something that touches all of us: our biological clock.

Three scientists—Jeffrey C. Hall, Michael Rosbash, and Michael W. Young—received the award for discovering how our bodies keep time at the molecular level. In simple terms, they revealed how our “internal clock” works, and why disrupting it can be so damaging to our health.

This clock silently manages almost everything in the body—when we feel sleepy or alert, our body temperature, hormone levels, and even how our cells repair themselves. But when we stay up too late, this delicate system is thrown off balance, and the consequences can be serious.

Their research found that:

Staying up late disrupts the body clock, paving the way for illness.
Lack of sleep can cause the brain to “eat itself”—astrocytes, specialized brain cells, begin devouring synapses.
If circadian-regulating genes fail, the risk of tumors increases.

The clear takeaway from this Nobel Prize-winning research? A familiar piece of advice: Don’t stay up late!

Yes, it’s something our parents, teachers, and elders have reminded us about countless times. But now, there’s a Nobel Prize—and 9 million Swedish kronor —to back it up.

Ancient Wisdom Meets Modern Science

Interestingly, the idea of the “body clock” isn’t new. Thousands of years ago, Traditional Chinese Medicine described how energy, or Qi, flows through the body in cycles. The 24-hour day was divided into twelve two-hour intervals, with each period linked to a specific organ system.

For example:

Between 1 a.m. and 3 a.m., the liver is at peak function, cleansing the blood and preparing the body for renewal.
From 3 a.m. onward, energy shifts to organs that support digestion and daily activity, such as the lungs, large intestine, and stomach.
By mid-afternoon, energy begins to flow inward again to support organs that restore and maintain the system, such as the kidneys and pericardium.

Understanding this Body-Energy Clock can help us better manage our sleep, meals, and mood. Modern science now echoes this ancient wisdom: align with your natural rhythms, and you’ll thrive.

The Role of Melatonin

Science also tells us about melatonin, often called the “sleep hormone.” Melatonin is vital for regulating the sleep-wake cycle. Levels begin to rise soon after darkness falls, peak between 2 a.m. and 4 a.m., and then gradually decline.

This explains why going to bed too late often leads to trouble falling asleep, and why sleep after 4 a.m. tends to be light and restless. For the best rest, it’s ideal to sleep between 11 p.m. and 4 a.m., when melatonin levels are highest and most restorative.

The Benefits of Sleeping Early and Rising Early

Research consistently shows that early sleepers and early risers enjoy powerful health benefits:

Better mental health: Early risers of all ages report more positive emotions and greater self-rated health.
Reduced risk of depression: A U.S. study found that going to bed just one hour earlier lowers depression risk by 23%.
Weight management: Staying up late disrupts hormones, leading to weight gain. Going to bed on time, combined with early rising and regular exercise, helps maintain a healthy weight.
Stronger immunity: Adequate sleep enhances immune function, reducing the risk of infections and chronic diseases such as heart disease, hypertension, diabetes, and stroke.
Sharper thinking: Early sleepers and early risers score 30% higher on word-association tests compared to night owls.

The message from both Nobel Prize-winning research and ancient health wisdom is clear: respect your biological clock.

Going to bed early and waking up early is not just about feeling more refreshed—it protects the brain, strengthens the body, improves mood, and may even add years to your life. So tonight, give yourself the gift of sleep—it’s worth more than 5 million!

In recent years, the scientific community has made significant strides in understanding the intricate processes that govern our health and longevity. One such breakthrough is the discovery of autophagy, a natural cellular process that plays a crucial role in maintaining our body’s health and vitality. This fascinating mechanism was brought to light by Japanese cell biologist Yoshinori Ohsumi, who was awarded the Nobel Prize in Medicine in 2016 for his groundbreaking research on how cells recycle and renew their contents.

What is Autophagy?

Autophagy, which literally means “self-eating,” is a process by which cells break down and remove damaged components, thereby promoting cell renewal and overall health. This self-cleansing mechanism allows cells to adapt to stress, eliminate dysfunctional proteins, and recycle cellular components for energy and repair. In essence, autophagy is vital for maintaining cellular homeostasis and preventing diseases, including cancer, neurodegenerative disorders, and metabolic conditions.

The Connection Between Fasting and Autophagy

One of the most effective ways to stimulate autophagy is through fasting. When we abstain from food for a certain period, our body shifts its focus from digestion to repair and regeneration. During fasting, the levels of insulin drop, and the body begins to utilize stored fat for energy, leading to a state of ketosis. This metabolic shift not only promotes fat loss but also triggers autophagy, allowing cells to clean out damaged components and rejuvenate themselves.

Research suggests that intermittent fasting or time-restricted eating can enhance the autophagic process, leading to improved cellular function and longevity. By engaging in these fasting practices, we can harness the power of autophagy to slow down the aging process and support overall health.

The Wisdom of Traditional Chinese Medicine

Interestingly, the principles of fasting and moderation in eating are not new concepts. Traditional Chinese Medicine (TCM) has long emphasized the importance of mindful eating and maintaining balance in our diets. One common guideline in TCM is to eat until we are about 70% full, rather than 100%. This practice encourages moderation and helps prevent overeating, which can lead to a host of health issues, including obesity, diabetes, and cardiovascular diseases.

The scientific foundation behind this advice is becoming increasingly clear. Overeating can lead to chronic inflammation, insulin resistance, and metabolic dysfunction, all of which can undermine our health and accelerate the aging process. By adopting a more mindful approach to eating, we can support our body’s natural processes, including autophagy, and promote better health outcomes.

As we continue to uncover the complexities of human biology, the relationship between fasting, autophagy, and aging becomes increasingly evident. The research by Yoshinori Ohsumi has opened new avenues for understanding how our cells function and how we can optimize our health through dietary practices. By embracing the wisdom of traditional teachings and incorporating fasting into our lives, we can take proactive steps toward enhancing our well-being and longevity.

In a world where the temptation to overindulge is ever-present, let us remember the power of moderation. Eating mindfully and allowing our bodies the time to repair and regenerate can lead to a healthier, more vibrant life. So, the next time you sit down for a meal, consider the age-old advice of eating until you’re 70% full, and give your body the chance to thrive.
