when should you have coffee daily?
Sources:
recommends delaying your caffeine intake until 90 to 120 minutes after waking up 1. This delay allows natural wakefulness processes to engage first, like the increase of cortisol levels, which naturally peak within the first half-hour to 45 minutes after waking. By waiting to consume caffeine, you can avoid a mid-afternoon energy crash that may occur if you have caffeine too early in the morning 2.
Furthermore, advises against consuming more than 100 milligrams of caffeine after 4:00 PM, and ideally, to limit your last caffeine intake to around 3:00 PM or even 2:00 PM 1. This is to prevent caffeine from disrupting the architecture of your sleep, as it can have effects lasting beyond its felt stimulation 3.
However, if you exercise first thing in the morning and prefer caffeine before your workout, then he suggests it's okay to consume it earlier 1. Just be aware that this might lead to an energy dip in the early afternoon.
Remember, this advice can vary from person to person, as individual tolerance and metabolism can impact how caffeine affects wakefulness and sleep 1.
