3 Worst Habits That Are ‘Destroying’ Your Sleep And Increasing The Risk Of Alzheimer’s, According To A Brain Health Expert

1. TV in the bedroom

TVs emit blue light, which interferes with your body’s production of melatonin—the hormone that helps regulate sleep. This can make it harder to fall asleep and reduce overall sleep quality.

Love says having a TV in your bedroom will lead to “poor quality sleep.”

2. Eating 2 hours before bed

Your body is less efficient at digesting food when you're lying down. Eating too close to bedtime can lead to indigestion, bloating, or acid reflux, making it harder to fall or stay asleep.

“If you eat close to bedtime, this impairs sleep. Digestion takes a lot of energy and blood flow, so if you have a full stomach when you go to bed, your body’s energy is being used to digest food rather than repair your body," he says.

To support better sleep, aim to finish your last meal at least 2–3 hours before going to bed, and keep it light and balanced if you're genuinely hungry.

3. Checking emails

Emails often involve work, stress, or to-do lists that activate your brain and increase anxiety or alertness—exactly the opposite of what you need before winding down.

Love cites the blue light emitted from the phone as something that can impair sleep and reduce melatonin. He also says thinking and reading about work or other emails can cause stress, and stress is the number one thing “impairing sleep in Americans.” He recommends checking them 2 hours before bed and spending the hour before bed reading a book, listening to music, or spending time with loved ones.
