The effects of having little sleep are well researched, and it’s proven that a lack of rest can lead to a number of problems, such as depression, heart disease and weight gain. However, the effects of athletes having little sleep go even deeper, with the smallest amount of low quality sleep impacting performance in a similar way to alcohol - diminishing concentration and reaction times. Lack of sleep has also been linked to increased levels of cortisol (commonly referred to as the stress hormone) and inhibits the production of glycogen and carbohydrates, which both provide the body with critical energy.
In the aforementioned study, it was found that cyclists that extended their sleep time by 30 minutes improved their 60-minute time trial performance by 3%. Going a step further than that, astudy by the Stanford University Basketball teamfound that when players increased their sleep time by two hours, their speed improved by 5%.
Therefore, authorities such as the National Sleep Foundation recommend that when training or preparing for an event, athletes adjust their sleep intake from the standard recommended amount to anything up to 10 hours.
HOW TO GET MORE SLEEP:
-Introduce a regular sleep schedule into your day to day by developing a routine where you do the same things before bed. Avoid using digital devices for an hour before bed if you can.
-Sleep at an optimal temperature. Sleep is induced and sustained when the body temperature is lower. Around 15 degrees is optimal.
-Don’t exercise too close to bedtime as this will increase your body temperature.
-Avoid caffeine and alcohol. Caffeine has a half-life which will stay in your system for a number of hours, and alcohol has been shown to reduce your sleep quality and amount of REM sleep.
- Take a nap. If you’re struggling to get your head down at night, supplement your sleep with a nap, but make sure you limit it to no longer than 30 minutes to avoid feeling groggy straight after. Napping earlier in the day is preferable. When you’re scheduling in some quality nap time, think of it as an extension of the previous night’s sleep as opposed to taking away from the next evening. If you can’t nap, don’t stress - you’ll still have utilised the time as an adequate period of rest!
