Veteran heart surgeon reveals importance of morning sunlight for health

Rising with the dawn has long been seen as a beneficial habit—and it's easy to see why being outside in the gentle light of the morning sun is appreciated as a straightforward yet influential practice that can enhance both physical and mental health.

This modest change in your daily routine can set a positive tone for a healthier, more balanced day by improving mood and energy levels while helping maintain the body’s natural cycles.

With 25 years under his belt, Dr. Jeremy London, a board-certified cardiothoracic surgeon, highlights the extensive health benefits, both physical and mental, of catching the day’s first light.

In an Instagram video from April 13, he stresses how embracing this morning sunlight practice can be profoundly beneficial to overall health and wellness.

Dr. London states that morning sunlight exposure at a low angle is vital for adjusting your sleep-wake cycle.

It signals to your brain that it's time to be active and attentive. This exposure to early light initiates a series of physiological changes essential for sustaining optimum daily performance, and it aids in managing melatonin production—helping you to wind down and sleep more naturally at night.

The surgeon says, “Morning sunlight at a low angle helps synchronize your circadian clock. This not only triggers when it's time to rise but also sets the timing for melatonin release later, aiding in restful sleep.”

Early morning sunlight, according to Dr. London, is well-known for promoting mental health, enhancing alertness, and even improving metabolic health.

By regulating important hormones like serotonin and cortisol, it fosters a more stable mood and maintains steady energy levels throughout your day.

He explains, “Spending time outside in the morning is one of the most beneficial actions you can take for mental tennis, metabolism, and mood—it elevates serotonin, manages cortisol, and keeps your energy consistent all day long.”

In addition to the physical and mental health advantages, waking up early gives you a peaceful and mindful way to start your day.

Rather than jumping into a fast-paced morning, it allows you to ease into your routine—taking a moment to enjoy your surroundings, taking a deep breath, and regrouping before the day’s activities begin.

Dr. London observes, “It's an excellent way to kick off the day. Enjoy the calm. Listen as the world awakens. It shapes the rest of the day. I realise busy schedules can make this challenging, but stepping outside even a few times weekly makes a difference.”
