The best time to drink coffee is never morning, but always an hour later than you think.

According to experts, the timing of your caffeine intake can significantly affect your energy levels and productivity. Drinking coffee too soon after waking up can lead to a surge in cortisol, causing anxiety and crashes that are worse than if you had skipped it entirely. Wait until cortisol is starting to drop, around an hour after your natural wake-up time.

But what about your body's clock? If you're a late riser but have to force yourself up early for work, drinking coffee immediately might be the best way to bridge that gap and stay alert at your peak alertness time. Conversely, if you're an early bird, avoid coffee until after 8 am when cortisol naturally peaks.

And don't forget to eat something before your cuppa. Drinking on an empty stomach can cause a sugar crash and make you feel even more jittery than usual. A small bowl of porridge or an apple can help steady your glucose levels, ensuring that caffeine's energy boost lasts longer.
