How does lack of sunlight affect sexual desire?

Less sunlight during winter can lower your serotonin and dopamine levels, which are the brain chemicals that regulate mood and pleasure. When these levels drop, you might feel tired and unmotivated, leading to a natural decrease in sexual desire.

Can light therapy help improve my sex drive?

Yes, using a light therapy box or getting more natural light can help regulate your mood and boost your energy. By alleviating the symptoms of seasonal depression, you may find your interest in sex and intimacy naturally returns.

How should I talk to my partner about my seasonal low libido?

Be open and honest about your mood changes so your partner knows it's about the season, not them. Sharing your feelings can reduce pressure and help you both find other ways to stay connected, like cuddling or just spending time together.

What can I do to boost my libido during the winter?

Prioritize self-care by staying active, eating well, and trying mindfulness practices to manage stress. You can also try scheduling intimate moments or simply focusing on non-sexual touch to keep the connection alive without the pressure.
