WHEN LIGHT GOES DARK
Think seasonal affective disorder (SAD) and your mind goes to winter, but there’s also a summer version. Both are caused by seasonal changes (in this case, light and heat) that can disrupt the internal clock responsible for your sleep and hormones. If light’s your issue, stay inside as much as you can or try to force your body into a strict pattern: a half hour of light each morning (around 6:30 am) and a consistent bedtime. For heat, crank the AC and take cool showers. Since SAD is annual, see your doc next spring to ask how to treat your blues proactively.
