Drink 500 ml of water before coffee

Free everyday life tip: Drink 500 ml of water before coffee (step 4 of 11 from "Morning Routine That Doesn't Need Willpower").

Fill a glass or bottle the night before and leave it on your nightstand or bathroom counter. As soon as you finish in the bathroom, drink the whole thing. You have been breathing and sweating for 7–8 hours without hydration — your body is mildly dehydrated, which contributes to that heavy, foggy feeling. Water does not replace coffee, but it starts the rehydration process so the caffeine works better when you get to it.

If plain water at 6:30 AM feels brutal, add a squeeze of lemon or a pinch of salt. The taste gives your brain something to register, which helps wake you up. Do not substitute juice or a smoothie — the sugar spike and crash defeats the purpose. Water first, then make your coffee whenever you are ready.
