12 Science Backed Tips To Help Improve Your Sleep

Often overlooked, this key piece of the wellness puzzle can have huge impact on the way you perform, look and feel. The foundation for recovery, sleep helps with the revitalisation of both physical and mental function. Being deprived of sleep can have a negative impact on body composition, hunger, hormone regulation, cognitive function, energy levels, risk of illness and injury and lead to a drop in performance. So it's fair to say it's something we need to think about.

Ok but what can help get you 7-8 hours of shut eye?

1. Spend more time outside

Daily sunlight can improve sleep quality (1) so make time to go for a walk or even exercise outdoors.

2. Reduce coffee and other stimulants later in the day

Caffeine can be present in the body up to 8hrs after consumption, which for some can negatively affect the quality of sleep (2).

3. Have a proper sleep schedule

Make the effort to go to bed and wake up at the same time each day. Having a set sleeping schedule can help with long term sleep quality (3), whereas irregular sleep patterns can alter the circadian rhythm. This is the process that helps align the body with sunrise and sunset.

4. Avoid alcohol

Alcohol can disrupt sleep quality and sleep patterns (4) so try and limit daily alcohol consumption.

5. Take a bath

A warm bath or shower before bed is an effective way to relax the body and improve sleep quality (5).

6. Invest

The quality of your mattress and pillows can have a significantly positive impact on sleep quality especially for those who suffer with back and neck pain (6, 7).

7. Make your room comfortable

A relaxing space to sleep that is cool, free from noise and bright lights can have a positive effect on sleep quality (8).

8. Reduce blue light

Light emitted from laptops, smart phones and tablets in the evening can pre- vent you from relaxing and reaching deep sleep (9). Download the app F.Lux to remove the blue light on your laptop. There are similar apps available for your smart phone.

9. Relax

Strategies such as reading a book, meditation/mindfulness, massage or listening to music can help relax the body and mind leading to better quality of sleep (10).

10 Don’t exercise late

Although exercise can have a positive effect on sleep, working out just before you go to bed may delay sleeping as a result of alertness and hormones such as adrenaline and epinephrine being released (11).

11. Eat high GI carbohydrates

Although your goal needs to be considered here, eating high GI foods such as white rice, pasta, bread, and potatoes may improve sleep quality if consumed more than 1 h before bedtime (12).

12. Eat enough

Dropping kcals can result in poorer sleep (12). This is another factor to think about when dieting. If you're goal is weight loss, aim for a small to moderate kcal deficit. For more help with your kcals and macros, either check out out free macro calculator or get a copy of the book, Fuelling The Functional Athlete.

10. Take some tryptophan

Consuming tryptophan (1 g) has shown a potential improvement in sleep quality (13). Foods high in tryptophan include nuts, cheese, red meat, chicken, turkey, fish and eggs.
