Common Insomnia Triggers

Certain habits show up again and again as drivers of poor sleep:

Alcohol — feels sedating but fragments sleep later in the night. See Does Alcohol Help You Sleep? What Research Really Says.
Screens and blue light before bed — delays melatonin release. See Digital Detox: How Unplugging Before Bed Improves Sleep and Focus.
Stress and an overactive mind — covered in the "tired but wired" guide above, with a simple brain-dump technique that helps.

When to Take It Further

If sleeplessness is happening most nights for several weeks despite trying the fixes above, that crosses from "bad sleep habits" into something worth a conversation with a doctor. Chronic insomnia responds particularly well to Cognitive Behavioral Therapy for Insomnia (CBT-I), which is considered the first-line treatment by sleep specialists — worth asking your doctor about specifically by name.
