Shorter days mean less sunlight, which reduces serotonin and increases melatonin, the chemicals that control your mood and sleep. So if you're having trouble oversleeping, craving carbs, or not wanting to do anything or see anyone, it could be your brain reacting to less light. Getting outside while it's still light out, eating real food, and keeping a consistent sleep schedule can help.💛 (As always, if you notice depression continuing for a long time or getting worse, talk to a healthcare provider.)
