Sleep

This February we’re focusing on sleep. It’s one of those things we simply can’t do without, but so rarely make enough time for. When we do, it can be unfathomably difficult to get a good and uninterrupted night’s sleep. But mental as well as physical wellness and sleep go hand in hand. It’s during sleep that our body’s tissues are repaired and its reserves restored and so for the sake of our health, it may be a good time to look at just how well we sleep.

We live in an information age, and sleep can offer us a welcome reprieve from the fairly constant bombardment of the senses by external stimuli. Indeed, it may well be one of the only retreats we have from the outside world, and therefore ensuring that the sleep we get is as good quality as possible should become an imperative. But the bombardment of the senses cannot but take its toll on the ability of our minds to ‘switch off’ and let us rest at night.

There are three types of insomnia: the first is the type that simply wont let you fall to sleep in the first place; the second takes the form of waking you up repeatedly during the night; and the third is the type that wakes you up early in the morning and prevents you from falling back to sleep.

There are three principal factors to take into consideration if you want to improve the quality of your sleep:

1) Environment
2) Behaviour
3) Diet

Environment
Ensuring that you sleep in a dark room can greatly improve the quality of your sleep. Tryptophan is the rarest of the amino acids. Under good dietary conditions, tryptophan is metabolised into serotonin, the ‘happy’ chemical which reduces anxiety and enhances mood. In the dark, serotonin is, in turn, metabolised into melatonin, the brain’s sleep hormone. So, try blocking out as much light as possible from your windows, and consider investing in a good eye mask.

You might also want to check the temperature of your bedroom. Ideally, your room will be 21 degrees. Similarly, check the noise level in your bedroom at night. Ear plugs might be useful.
Behaviour
Routine can be important in establishing a healthy sleep pattern. But admittedly it can be difficult to achieve. You should aim to wind down about an hour before you go to bed. Do something you find relaxing, switch off the tv and computer, lower the lights… Try to associate your bed only with sleep. Avoid watching tv or reading (particularly more engaging books) in bed.

Although a good level of exercise is good for you and can aid healthy sleep, try to avoid exercising just before going to bed. Choose to exercise in the morning, or late afternoon instead.

People have different needs when it comes to the quantity of sleep required. On average we sleep 2 hours less than our relatives only 50 years ago. While they used to sleep 9 hours a night on average, now we only sleep 7. And many of us wont always manage that! If you are experiencing insomnia, try waiting until you are tired before going to bed (but avoid going beyond tiredness too). You can also try adopting the 15 minute rule: if you don’t fall asleep within 15 minutes of getting into bed, get up and do something else for a while, in another room even, before you try again. It’s important to try and avoid getting anxious because you can’t sleep as this will only exacerbate the problem.

Diet
We’ve already identified tryptophan as important in aiding sleep. Tryptophan is a component of protein, but simply by eating protein-rich foods may not help. In fact, it can make things worse. Tryptophan can only access the right part of the brain to induce sleep if combined with a carbohydrate. Tryptophan-rich foods include pumpkin and squash seeds.

So while moving towards a higher-protein diet will help overall, we need to ensure we consume a certain amount of carbohydrates too, and try to avoid the tendency to overload our plates with protein at dinner time. We have lost our healthy intuition when it comes to food, and because of the way the modern world works, we often don’t eat the right combination of foods at the right time.

Try to include a rich source of protein in combination with a carbohydrate at breakfast time (breakfast cereals for example tend to be carb heavy, and more often than not, they consist of high GI carbs). It’s also far better to have a bigger meal at lunch time in order to avoid the need to over-consume protein closer to bedtime. If you ensure you consume good sources of protein at breakfast and lunch time, this will help.
When it comes to diet, you might also want to check your caffeine in-take. Caffeine has a stimulating effect, and it accumulates in your body, so try to avoid drinking caffeinated drinks after lunch. There are plenty of herb teas out there to be enjoyed as alternatives.

Alcohol can also impede healthy sleep patterns. Although we might fall to sleep more quickly after a glass or two, alcohol actually suppresses our ability to experience deep sleep, so we’re unlikely to wake up feeling well-rested.

Calcium and magnesium can help by calming the body and mind. Magnesium is a particularly important mineral in which the majority of us are likely to be deficient. Intensive farming and the resulting depletion of our soils means that we can no longer get a good enough level of magnesium from our food. The milling of grains and the refining process of food further reduces the level of magnesium available to us. Leafy greens are always a good choice of veg, and should be part of your daily diet. Green foods are rich in calcium and magnesium, magnesium being at the centre of every chlorophyll molecule.

Other calming foods include chia seeds, mulberries and lemon, and silicon-rich foods (which aid calcium metabolism) like barley and oats, rice and mushrooms. Herbs and spices which may help include basil and dill, chamomile and valerian.

When it comes to meal times, again strive for regularity and avoid eating at least an hour before bed. I try to eat as early as possible. Your body has to work to digest food, so reducing its need to work when it should be resting can only be a good thing. When it isn’t trying to digest food, your body will use its energy to repair, restore and heal instead.
