The Effects of Diminished Light and The Role of Vitamin

Seasons have long held sway over the ebb and flow of human life. As the earth rotates and our

hemisphere tilts away from the sun, we face fewer daylight hours and often a dip in mood and energy. This interplay between seasonal change and human well-being is fascinating, and it is particularly notable when considering the effects of decreased light exposure and the significance of Vitamin C.

Diminished Light Exposure: Seasonal Affective Disorder (SAD) and Beyond. What is Seasonal Affective Disorder?

Seasonal Affective Disorder (SAD) is a type of depression related to seasonal changes. It begins and ends at about the exact times every year, with symptoms typically starting in the fall and continuing into the winter months.


Feeling depressed nearly every day

Losing interest in activities once enjoyed

Changes in appetite or weight

Difficulty sleeping or oversleeping.

Energy drain or feeling sluggish.

Feeling hopeless or worthless

Why does this happen?

The exact cause of SAD is still under research, but shorter daylight hours and less sunlight in fall and winter can lead to:

Disturbed circadian rhythm: The decrease in sunlight might lead to disruptions in the body and internal clock, which signals sleep and wake times.

Drops in serotonin: Reduced sunlight can cause a decrease in serotonin, a neurotransmitter that affects mood, leading to depression.

Changes in melatonin levels: The change in seasons can disrupt the balance of the bodies melatonin levels, which play a role in sleep and mood.

  1. Vitamin C: The Unsung Hero of Winter Health

While many associate Vitamin C with boosting the immune system and fending off the common cold, it has additional roles that may be particularly significant during the seasons with reduced sunlight.

Mood and Brain Health:

Vitamin C plays a crucial role in synthesizing neurotransmitters, including serotonin. A deficiency might disturb the serotonin synthesis, exacerbating or potentially triggering depressive symptoms like those seen in SAD.

Collagen Production:

Vitamin C is essential for producing collagen, a protein that helps wounds heal. Our skin can become more fragile, dry, and prone to damage in winter due to cold winds and indoor heating. Ensuring adequate Vitamin C intake can support skin health during these challenging months.

Antioxidant Properties:

As an antioxidant, Vitamin C protects cells from damage caused by free radicals, exacerbated by stress, poor diet, or illnesses common in colder seasons.

  1. Recommendations:

Light Therapy: Light therapy or phototherapy has been found effective for those affected by SAD. It involves sitting near a special lightbox for a specific time each day.

Stay Active: Engaging in physical activity, even indoors, can help elevate mood and counteract some effects of reduced sunlight exposure.

Maintain a Balanced Diet: Incorporate Vitamin C-rich foods such as oranges, strawberries, bell peppers, and broccoli. If necessary, consider a supplement after consulting with a healthcare professional.

Seek Support: If feeling consistently down, speaking with a healthcare provider or therapist is essential. They can offer guidance tailored to your specific situation.

In conclusion, as the seasons shift and daylight dwindles, it is essential to recognize the effects this change can have on our well-being. By understanding the importance of light and the multifaceted role of Vitamin C, we can better equip ourselves to maintain good health and a positive mindset throughout the colder months.
