How Winter Light Loss Influences Health — and What You Can Do

Winter Light

Now that winter is upon us, daylight hours are at their shortest. The sun sets early, leaving us with longer periods spent indoors under artificial light. Although many of us are already used to this seasonal shift, it can still significantly impact our physical and mental wellbeing.

Health experts have pointed out that reduced exposure to natural light, which is typical in autumn and winter, is linked to changes in brain chemistry and our internal body clock – also known as the circadian rhythm. This shift can affect hormone production, specifically melatonin (which regulates sleep) and serotonin (which influences mood, appetite and energy levels).

As sunlight diminishes, melatonin levels tend to rise, while serotonin levels may fall, contributing to feelings of sleepiness, low mood and decreased motivation. This pattern is often associated with Seasonal Affective Disorder (SAD) and the so-called ‘winter blues.’

The effects of reduced daylight go beyond just emotional changes. A lack of sunlight also lowers vitamin D production, which is essential for immune function, bone health and mood regulation. Fortunately, there are simple steps you can take to support your wellbeing during this time:

  • Get outside in daylight when possible. Even short walks during brighter parts of the day or sitting near windows can help your body absorb natural light and synchronise your internal clock.
  • Stay active. Regular exercise boosts mood and energy by increasing serotonin and endorphins — the body’s natural ‘feel-good’ chemicals.
  • Consider light therapy. Bright light boxes that mimic sunlight are often recommended for alleviating SAD symptoms and can help regulate sleep patterns and mood when consistently used in the morning.
  • Maintain a routine. Keeping regular sleep and activity schedules stabilises your body clock and supports overall health.
  • Look after your diet and vitamin D levels. Consuming foods rich in vitamin D and taking a supplement, if recommended by a healthcare professional, can help support mood and immune function during the darker months.
  • Stay socially connected. Staying in touch with friends, family or community groups enhances emotional wellbeing and counters feelings of isolation.

These lifestyle practices can help your body and mind adjust to seasonal changes while strengthening your resilience and overall wellbeing.

Going to church can be a great way to stay socially connected. At the Universal Church, our doors are open to you, whether you want to take part in our services, benefit from our community outreach initiatives, or simply stop by for a chat.

On Tuesdays, we hold the Health Day meetings, where we share more tips on caring for your wellbeing, and teach you how you can use your faith as a complement to medical advice. Join us at your nearest Universal Church branch as we proceed with the Novena of the Challenge of the Cross.
