“I look after my father and often notice a change in him in the darker winter months. It’s like he is not his usual self and loses some of his humour and sparkle. Is seasonal affective disorder a real thing and is there anything that can help him? I have been Googling things and I see light box therapy mentioned a lot. Does this really work and might it be worth investing in one for him?”It is very common for people to feel a bit down in the winter months, sometimes called the “winter blues”.
It is not known exactly what causes SAD, but it is thought that lower levels of sunlight in the winter months can trigger changes to the body’s circadian rhythm, as well as lowering production of serotonin and raising melatonin . Symptoms can range from mild to severe, and at the more severe end can include thoughts of suicide.
Have you spoken with your father about what you have noticed? It might help to know how he feels about his mood at these times, and what he generally finds helpful to lift his spirits. If he is able, a good place to start boosting one’s mood is increasing fresh air and natural light in the day time; getting out for walks in the morning and as much movement during the day as he can manage. Help him find hobbies and see loved ones that bring him joy.
Light box therapy is a popular treatment, and you can buy your own lightbox to use at home. The light box mimics natural light, and treatment involves sitting in front of it for about 20-30 minutes per day, usually in the morning. The scientific evidence for its effectiveness is mixed, but side effects are minimal, so it can be worth a try if it sounds appealing.
If your father’s mood does not improve or worsens, it would be best for you or him to speak with his GP about getting more help. Professional help for SAD is the same as that for other types of depression, and can include psychotherapy or antidepressant medications.‘He’d twist things I said to make me feel that I was in the wrong.
