Nutrition for Darker Winter Days: Beating Fatigue & Low Mood
s winter settles in and daylight hours shrink, many people experience fatigue, sluggishness, and dips in mood. Shorter days disrupt our circadian rhythm, reduce sunlight-driven vitamin D production, and affect neurotransmitters like serotonin and melatonin. The good news? Thoughtful nutrition and targeted supplementation can help support energy, mood, and resilience during these darker months.
Below is a science-backed guide to staying well—and an invitation for brands looking to develop winter-focused nutrition formulas with Northfield Laboratories Inc., your partner in custom supplement development and toll manufacturing.
Why Winter Impacts Energy & Mood
1. Reduced Sunlight = Lower Vitamin D
Vitamin D plays a key role in immune health, mood regulation, and energy. With shorter days, many people fall below optimal levels.
2. Melatonin & Sleep Cycle Disruptions
Darker mornings and earlier sunsets signal the brain to produce more melatonin, making you feel tired earlier and more often.
3. Serotonin Drops
Less sunlight also affects serotonin, a key hormone for mood and motivation.
