The Science Behind Insomnia: Why Can’t You Sleep?

If you struggle to fall asleep or stay asleep, you may be dealing with insomnia. But what causes it? Here’s what science tells us about insomnia and how to overcome it.

What is Insomnia?

Insomnia is the inability to fall or stay asleep, leading to fatigue, irritability, and poor concentration.

Common Causes of Insomnia

  1. Stress & Anxiety – An overactive mind makes it hard to relax.

  2. Screen Exposure – Blue light reduces melatonin, the sleep hormone.

  3. Irregular Sleep Patterns – Inconsistent bedtimes confuse your body clock.

  4. Caffeine & Alcohol – Stimulants and alcohol disrupt natural sleep cycles.

  5. Medical Conditions – Issues like chronic pain, sleep apnea, or depression can contribute.

How to Combat Insomnia

  • Practice Relaxation Techniques – Meditation, deep breathing, or gentle yoga can reduce stress. Tools like our SleepPulse CES Sleep Aid Device can help kickstart that relaxation response.

  • Create a Sleep-Inducing Environment – Keep your bedroom cool, dark, and quiet. A nightly LumiSleep LED Light Therapy session can help reinforce this wind-down cue.

  • Limit Caffeine & Alcohol Intake – Avoid them at least 6 hours before bedtime.

  • Use Sleep Supplements Wisely – Melatonin may help, but it’s not a long-term fix.

  • Stick to a Routine – Go to bed and wake up at the same time every day.

Understanding what causes your insomnia can help you take the right steps to fix it!
