Matthew Walker’s book; Why We Sleep was a game changer for me. Whilst I’d known for a long time that sleep was important; the extent to which was unclear. Matthew puts it succinctly when he says “There is not one process in the human body, (that we’re aware of) that isn’t improved by sleep”. Indeed, the International Agency for Research on Cancer (part of the WHO), concluded in 2007 that night shift work is a probable human carcinogen1

Sleep loss is linked to the acceleration of a plethora of common issues, including:

  • Cancer
  • Diabetes & Weight Gain
  • Heart Disease
  • Poor fertility
  • Weakened immune system
  • DNA damage

But what is adequate? 8 hours appears to be the minimum we should strive for. Apparently there’s a tiny % of people with DNA mutations that allow them to function well below 8 hours; but it’s a minority.

Matthew’s Tips for Good Sleep

Below I’ll summarise Matthew’s 12 key tips for good sleep:

1. Stick to a sleep schedule

We should aim to go to bed and wake up at the same time each day. People generally have a hard time adjusting to changes in sleep patterns. Unfortunately sleeping late on weekends doesn’t make up for poor sleep during the week. If necessary, set an alarm for bedtime. Matthew emphasizes this is the #1 priority from the list; stick to a regular sleep schedule.

2. Don’t exercise too late in the day

Exercise is great, and we should try to exercise at least 30 minutes on most days. But try to time it no later than 2-3 hours before bed.

3. Avoid caffeine & nicotine

Colas, coffee, teas (that aren’t herbal) and chocolate contain caffeine, which is a stimulant. Even consuming these in the afternoon can have an affect on your sleep. Nicotine is also a mild stimulant, and smokers will often wake up earlier than they would otherwise, due to nicotine withdrawal.

4. Avoid alcoholic drinks before bed

The presence of alcohol in the body can reduce your REM sleep, keeping you in the lighter stages of sleep.

5. Avoid large meals and beverages late at night

A lights snack before bed is okay, but a heavy meal can cause digestive issues, which interfers with sleep. Drinking too many fluids can cause freuqent awakenings to urinate.

6. Where possible, avoid medicines that delay or disrupt your sleep

Some commonly prescribed heart, blood pressure or asthma medications, as well as some over the counter and herbal medicines for coughs colds or allergies can disrupt sleep patterns. If you have trouble sleeping, it may be worth speaking to your doctor or pharmacist to see if any of the drugs you’re taking may be contributing to this. It may be possible to take them earlier in the day.

7. Don’t nap after 3pm

Naps are great, but taking them too late in the day can make it hard to fall asleep at night.

8. Make sure to leave time to relax before bed

It’s important to have time before bed to unwind. Try to schedule your days so that there is time to relax before bed.

9. Take a hot bath before bed

The drop in body temperature after a bath may help you to feel sleepy, and the bath can help you to slow down and relax before bed.

10. Have a dark, cool (in temperature), gadget free bedroom

We sleep better at night if the temperature in the room is kept on the cool side. Gadgets such as mobile phones and computers can be a distraction. A comfortable mattress and pillow can set you up for a good sleep. Those with insomnia will often watch the clock, turn it away from view so you don’t have to worry about the time while trying to sleep. Use these tips to optimize your sleeping space.

11. Get the right sunlight exposure

Sun exposure during the day helps us to regulate sleeping patterns. Try to get outside in the natural sunlight for at least 30 minutes per day.

12. Don’t stay in bed if you (really) can’t sleep

If you find yourself still in bed for more than 20 minutes, or you’re starting to get anxious in bed, get up and do something else until you feel sleepy. Anxiety whilst trying to sleep can make it harder to fall asleep.
