International Day of Light: A Lifestyle Medicine Perspective

May 16th, 2024 marks the International Day of Light, an occasion to consider the essential role of light in health and wellbeing. This blog explores practical ways to utilize light to enhance our physical and mental health.

Our Circadian Rhythm

Our bodies are governed by an internal clock known as the circadian rhythm, regulating sleep, metabolism, and hormone production. Natural daylight maintains this rhythm, whereas artificial light at night may disrupt it, leading to sleep issues and metabolic disorders. Aligning daily routines with natural light patterns fosters better health and well-being.

Mood, Sleep, and Hormones

Sunlight triggers serotonin, enhancing mood and happiness. Conversely, light exposure reduces melatonin production, crucial for restful sleep, particularly important during shorter winter days to combat Seasonal Affective Disorder (SAD).

Vitamin D and Sunlight

Sunlight spurs Vitamin D production, essential for bone health and immune function. While certain foods provide Vitamin D, sunlight exposure remains paramount for sufficient levels, alongside possible supplementation.

Incorporating Light into Daily Life

• Outdoor Time: Regularly spend time outdoors during daylight to maintain your circadian rhythm.
• Indoor Lighting: Consider light therapy lamps or full-spectrum lighting to mimic natural light indoors.
• Sleep-Friendly Routines: Minimize blue light exposure from devices before bedtime to support melatonin levels and ensure quality sleep.

Consult health professionals at Extracellular for personalized advice on Vitamin D deficiency or SAD.

Conclusion

The International Day of Light serves as a reminder of the profound impact light has on our lifestyle. By harnessing the power of natural light, we can enhance our mental and physical health for a balanced lifestyle.
