We know that caffeine does many wonderful things, the more obvious ones including improved mood, cognition, and exercise performance. We also know that short periods of sleep (naps) – with and without sleep deprivation – can improve mood, sleepiness, and some types of exercise performance.
Research has consistently shown that the benefits of consuming caffeine close to napping are additive, with the majority of such data being collected in studies looking at sleep-wake issues in night shift workers, as well as the suppression of sleepiness in drivers. Though I’m not aware of any research that has used a combination of caffeine and napping on exercise performance, I and others have experienced consistent success with this in athletic and general populations.
Who is this for?
At some point or other, everyone incurs a degree of sleep debt, reduction in productivity due to sleepiness, moodiness and overall lack of motivation. Whether you’re playing at Wembley or on a field on a Sunday morning, you will often need to be at your best performance-wise. As such, pretty much everyone can benefit from caffeine, napping, or combining the two. Using the image and the information below, you can tailor these recommendations to best suit your needs.
The amount of caffeine to ingest will mainly be influenced by the desired outcome (e.g. reduced sleepiness, improved productivity, increased athletic performance etc.). Generally, only small-moderate amounts of caffeine are required to reduce sleepiness (around 50-100mg). For improving football performance, around 200mg is more appropriate.
This mainly comes down to three choices: pills, coffee or gel. Caffeine powder came and went pretty quickly. The dose seems to matter more than the caffeine source, so go with your personal preference. That said, if you intend to consume caffeine right before a nap, I’d stick to gel or pills as it’s quicker than consuming coffee (unless you go for a shot or two of espresso). If you try to drink a cup of coffee, it's unlikely that you’ll fall asleep since the caffeine will have already taken effect. With a gel or pills, blood caffeine levels will peak at around 45-60 minutes after their ingestion, so there’s time to sneak a quick nap in before it takes effect.
If a nap is long and contains slow-wave sleep, mental performance and mood are temporarily worsened until you’ve properly woken up. This is called ‘sleep inertia’. To avoid it, keep naps to a maximum of around 25-30 minutes, with about 15-25 minutes being ideal.
For improved performance, if you can do so, then utilising the caffeine-nap protocol about 90-120 minutes before the game or key training session is recommended. It’s worth trialling this during training first before a game situation though. If you’re just struggling to get through the day, then squeezing the protocol into your lunch break is doable for many. That said, if you can do so, any time of the day is fine providing that you give yourself around 6-8 hours or so between consuming large quantities of caffeine and bedtime.

Today we’re thrilled to announce our Official Supplements Partnership with West Ham United.
This partnership represents a second Premier League team for Soccer Supplement, as we now work with over 100 clubs and sell into over 30 countries, this is a giant step for the business as we continue to grow. The Hammer’s medical team chose our products which are specifically designed to be used by footballers at all levels to improve fitness, performance and recovery, while training or on matchdays.
Football is a high intensity sport, and requires endurance to be able to play for the whole 90 minutes, whilst maintaining skill levels and the ability to perform multiple sprints to beat your man, get up and down the touchline or work box to box in the middle of the field. Analysis of football shows that most mistakes are made towards the end of the game, as well as less distance being covered and less sprints made. The primary reason for this is fatigue, so it’s important to optimise our diet to fuel properly and perform for the whole game.
