First, notice the pattern before it takes control. If you know you’ve spent past winters hiding under blankets, get ahead of it. Speak to your GP or a mental health professional before symptoms get severe. People who’ve had SAD more than once often do best if they start treatment as soon as autumn rolls in.

Light therapy is one of the go-to fixes for SAD. You sit by a 10,000-lux lightbox for about half an hour each morning, ideally before work or school starts. It’s not for everyone, though; if you have eye issues or you’re on certain meds, you’ll want medical advice first.

Therapy can help, too. Cognitive behavioural therapy (CBT), adapted for SAD, teaches you strategies to outsmart those winter thought traps and keep routines alive. Antidepressants are another option, sometimes used on their own or alongside other treatments.

However, don’t underestimate the everyday stuff. Make sure you get outside in the daylight and walk just after sunrise if you can stomach it. Keep a steady sleep schedule, exercise, eat proper meals, and don’t cut yourself off. Even if it means scheduling regular calls or meet-ups, staying connected matters. People sometimes try vitamin D supplements since you’re not seeing much sun, but those alone aren’t proven cures for SAD, though they do help some.

When climate worries are adding to winter blues, try connecting with like-minded folks or support groups. Taking small, concrete steps, like getting involved with local environmental causes, can help you feel more in control. Climate therapists can also provide a space to talk through worries about the world without downplaying those feelings.
