What is the 2 hour coffee rule?
Drinking coffee immediately can interfere with this natural process, potentially reducing caffeine’s effectiveness. Instead, aim to have your first coffee about 1-2 hours after waking up. This allows cortisol levels to stabilize, making caffeine more impactful for energy and focus. Dentists generally recommend waiting at least 30 minutes after consuming coffee – or any acidic beverage – before brushing your teeth. This gives your saliva enough time to neutralize the acids and reharden your enamel, greatly reducing the risk of enamel damage.
