The Easiest Way to Combat Seasonal Mood Changes

Many people feel more tired, low, or unmotivated in the winter. The biggest reason? Less daylight.
Light plays a major role in mood, energy, and sleep — so getting more light is one of the most effective ways to feel better during darker months.

Why Light Matters

  • Light helps your brain make serotonin, which supports mood.
  • It lowers melatonin during the day, so you feel more awake.
  • It helps reset your internal clock, improving sleep.

Even on cloudy days, outdoor light is much stronger than indoor light — and just a short dose can help.

How to Use Light to Boost Your Mood

  1. Get morning light (10–20 minutes).
    Step outside within one hour of waking. A short walk or sitting by a bright window works.
  2. Bring in more indoor light.
    Open curtains, sit near windows, and turn on extra lights in the early morning or late afternoon.
  3. Consider a light therapy lamp (if recommended).
    Use a 10,000 lux lamp for 20–30 minutes in the morning. Ask your provider if it’s right for you.

Other Simple Ways to Improve Winter Mood

These support your light routine:

  1. Move gently each day.
    Try a 5–10 minute walk, stretching, or indoor exercises.
  2. Keep a steady sleep schedule.
    Consistent bedtimes and wake times help your body adjust to darker days.
  3. Stay socially connected.
    A quick call or check-in can reduce loneliness and boost mood.
  4. Eat foods that support steady energy.
    Pair carbs with protein and add veggies, beans, or omega-3s.
