Why is Sleep so Important for Athletic Performance and General Health

July 29, 2022 By Jill Roberts

Why is Sleep so Important for Athletic Performance and General Health

Could your performance get better just by improving your sleep?

Sleep has, for a not insignificant amount of time associated with sports performance.
In short, the theory has been that good sleep leads to improved performance and poor sleep will impair performance.

The association with good or bad sleep has been premised upon the duration of the sleep, but is that really an accurate measure of sleep quality?

This article will explore some of the more delicate points relating to sleep quality as well as provide some scientific background on the purpose of sleep as a human process.

Russell Foster is a British Circadian neuroscientist: His wonderful Ted Talk on "Why do We Sleep"

What is Sleep and How Does it Work?

Sleep has such a profound effect on performance and health because of the vast number of vital processes that are dependent upon it. When we sleep the body, in fact, carries out housekeeping duties; methods that help you deal with physical and mental stress, information processing and memory formation, repair and restoration of tissues

Cues such as falling temperature and light levels are picked up by the sensory nervous system and relayed to the brain which kicks off the production of the hormone melatonin, the trigger for sleep and everything that goes with it, and as such a critical player in your health.

Once sleep has been initiated the brain goes through a series of cycles that appear to be the crux of the issue, indeed it has been suggested that it is not the duration that counts, but rather the number and completeness of cycles you go through.
This cycle is repeated, usually from about 4-6 times in an 8-hour sleep period. So sleep quality is defined by the cycle but how many is enough?

Training and Recovery, the Impact of Sleep

Sleep triggers the rage of production of hormones, this hormonal milieu includes hormones like growth hormone and testosterone that are responsible for the repair and regeneration of tissues intrinsically involved in physical performance, and research shows that lack of sleep quickly impacts all sorts of physical tasks, with research covering weightlifters, cyclists, runners and so on.

The impact is two-fold, over the short term sleep issues have a massively adverse effect on the nervous system reducing strength endurance, concentration, and coordination - all vital for sports and training.

Over the longer term disruptions in hormone output will affect the body’s ability to recover the tissues such as muscle as well as impair carbohydrate storage efficiency and reduce immune competence.

In short: a bad night’s sleep with leave you weak and uncoordinated and over A long time you’ll be tired, fat, and ill. Getting enough, quality sleep is essential.

How Much is ‘Enough’?

For most people getting less than 7 hours really starts to affect performance and health and many sleep coaches agree that the aim should be 8 hours. Studying historical texts and populations where there is no electric light or TV shows significantly longer sleep durations for example 9-10 hours. My advice: Aim for 9, you’re bound to fall short but still will be OK.

Also remember that stress from high-pressure work situations or from lots of physical training can also increase needs significantly, and although the right amount of stress can make for deeper sleep, for example, a well-designed training program, other things, like too much training will disturb it.

Getting Quantity and Quality Right

Duration is necessary but so is quality and sleep 'hacks', habits, and little tricks that improve the environment and so can set you up for that deep, restful night’s sleep.

The Sleep Hacks

The environment must be comfortable, cool, and dark:

The Bed

  • Frame
  • When your sleeping partner stirs or fidgets then usually so will you so get as big a bed as possible.
  • If you get hot easily standard open frame bed with space for the air to circulate underneath will make you more comfortable, especially in summer.
  • Mattress
    A decent mattress will be some of the best 'health & fitness dollars' you ever spend.
    Memory foam mattresses are great but again if you get hot easily closed and open spring mattresses will allow more airflow.
    And, particularly you can choose the night therapy mattress for restful sleeping. It's just great to generate high-class comfort and ensure the expected level of body support needed for quality sleep.
  • Pillow
    These lose both their shape and hygiene levels and should be replaced at least every few years. If you sleep on your side explore the range of orthopedic pillows.

The Room:

  • Reduce the Temperature
    a  few degrees cooler than your lounge
  •  Block out the Light
    Light means it is time to wake up to make sure your curtains are light proof or try the ‘blackout kits’ available in stores like Amazon.
  • Cut the Noise
    Environmental stimuli will disturb sleep so take a good look at this, maybe look at white noise generating sleep aids.
  • Remove the electronics
    TVs, computers of all types as well as smartphones produce a lot of blue light that inhibits melatonin production. Research shows this link and also shows that couples who removed the TV from the bedroom had sex more often … you might want to leave the TV in the lounge.

Hacking Your Sleep Behaviour

What you do before bed affects sleep onset, duration, and quality

Several Hours Before Bed:

  • Do a Brain Dump
    Make sure you get your tasks down in writing and relax.
  • Avoid caffeine
    The 'half-life' of caffeine is about 5. I usually advise people to cut it a minimum of 5-6 hours before bed.
  • Train earlier
    Working out will help sleep quality but try not to train too close to bedtime. Yoga or meditation may help at the end of a session.

1 Hour Before Bed:

  • Reduce fluid intake
    reduces nocturnal toilet trips.
  • Get a ‘Pre Bed Routine’:
    This cues the subconscious that sleep is imminent and should be boring and easy: fold clothes or pack food for the next day.
  • Schedule sleep
    An important aspect of ‘sleep hygiene is going to bed at the same or at least a very similar time every night..
  • Cool the rooms
    Cooling signals sleep, so cool the room by about 2 degrees
  • Dim room lights, turn off your TV, computer, and smartphone
    Avoids stressful emails and looks after your melatonin production.
  • Food - Avoid liquid and/or salt as they may mean nighttime trips to the bathroom.
    Large amounts of fibrous carbs or fatty foods like cheese may sit on the stomach and disturb sleep as can spicy foods.

After Lights Out:

  • Nocturnal manoeuvers in the dark
    If you do need to get up at night for any reason they don’t turn on the light unless you have to.
    In fact, whatever you get up to after lights out, do it with the lights off.
  • Awake with ideas:
    If you get the spark of inspiration jot it down in the dark and go back to sleep – it helps to have a clear bedside table, a big piece of paper to aim at and a pencil sharpened at both ends.

Take Away Messages

  • Your environment cues sleep onset
  • Stress, both physical and mental will inhibit the onset of sleep and may reduce the quality
  • Staying asleep depends mainly on your environment
  • A few changes in the environment and pre-sleep behavior can work wonders
  • Sleep triggered internally rather than by medication is, by far, the best sleep

These practical tips will help you sleep like a baby, that deep, restful sleep that we all crave is only a few little habit changes away, but you have to try them for them to work
