Why does Winter affect our Mental Wellbeing?

Reduced Sunlight Exposure –

Less sunlight in winter months can lead to:
Lower serotonin levels, a brain chemical that affects mood.
Disruption of circadian rhythms, which regulate sleep, mood and energy.
Vitamin D deficiency, which is linked to depression.

Seasonal Affective Disorder (SAD)

SAD is a form of depression that follows a seasonal pattern—usually starting in Autumn or Winter and improving in Spring.
Symptoms include: Low energy, Social withdrawal, changes in appetite (especially craving carbs) difficulty in concentrating and feeling hopeless or worthless.

Shorter Days and Longer Nights –   

Early darkness can make people feel like the day is “over” too quickly leading to: Less time spent outdoors, reduced physical activity, less social interaction and a sense of isolation if you live alone.
Cold Weather and Limited Mobility can discourage outdoor activity and exercise both important for mental health. It can worsen symptoms for people living with chronic pain, which can contribute to depression.
Social Isolation during bad weather, shorter days can lead to more time spent alone in doors, reducing social interaction.

Holiday Season Stress –
Winter includes important holiday dates—Christmas and New Year which can be emotionally triggering for those who are grieving, lonely, or estranged from family. This time can also be
stressful due to financial pressure, social obligations or unrealistic expectations.

Remember that older neighbours, friends and family members, may need extra help over the winter. Keep in touch with them, especially if they live alone. Make sure they’re stocked up with enough food supplies for a few days, in case cold, ice or snowy weather stop them from going out.
If they do need to go out in the cold, encourage them to wear shoes with a good grip and a scarf around the mouth to protect them from the cold air, and to reduce their
risk of chest infections.
Make sure they get any prescription medicines before the Christmas holidays start and if bad weather is forecast.
If they need help over the holiday period when the GP practice or pharmacy is closed or they’re not sure what to do, NHS 111 can help. The service is available online at
111.nhs.uk and also by phone.
By answering questions about their health problem they will be told what to do and where to go.
