Coronavirus: Tips for routine, exercise and diet during the lockdown

Dr Gladys Pearson's advice to help people stay healthy while remaining at home

Routine

Eating even more healthy than your normal habit and enjoying a healthy sleep hygiene is important.

You need to maintain a consistent sleep and meal pattern, otherwise your body just loses its habitual hormone fluctuation thereby adding to its stress and decreasing its ability to fight off infections.

I would say stick to your eating routine because your hormones and your sleep quality is affected by how your body is used to the feeling such as whether your stomach is usually more full or not before you fall asleep.

Whether you normally eat early or later, the timing of your evening meal gives a trigger to the body to indicate whether you are about to start winding down and sleep.

So if you are used to eating closer to bed time, continue to do that, as it will help with your sleep routine.

Ideally, however, it is better to adopt a healthier habit of leaving a good one to two-hour gap between your last meal and sleeping.

If you have a habit of eating two, typically three, meals a day then it’s preferable to continue that because your body is trying (during this self-isolation) to cope with so many stresses and outside influences.

For me, stress feels like it's going to be the highest-priority issue people have, from being stuck indoors (or limited outdoors activities), or from risk of job losses, or adapting to problems about how to do their jobs effectively from home. It could cause a cascade of negative physiological events.

Managing stress is such a big concern that, even though I'm not a psychologist, the idea of meditating, undertaking breathing exercises or just finding quiet time seems sensible because if you can manage the stress, the rest will come good: your sleep hygiene will be better, your eating habits will be better.

Exercise

It varies a lot for two reasons.

People's preferences means that if you're a morning person, you'll probably feel more motivated to exercise in the morning than if you're an evening-type person.

However, physiologically, our research has shown the evening seems to be the best time of day for exercise, particularly when you're trying to build up muscles, because in the morning your body is still in a hormone balance that favours muscle breakdown more so than building.

And we're probably more in a period when we're more likely to be losing muscles because for the most part, most people won't have access to, for instance, weight lifting equipment or being able to go for a long run to the same extent.

I think it is better to do 30 minutes of exercise than not do anything at all.

If you're in the house, find excuses to attend to small physical jobs like clearing the gutter or arranging your wardrobe by colour - just a succession of these gentle activities throughout the day is beneficial.

It may seem a small movement but it's enough and all these little things are better than sitting and watching TV or on the phone for prolonged periods of time.

I am not suggesting that those activities solve the problem per se but our research suggests that even doing this whilst standing and shifting from one leg to another, stretching, helps.

Also, for example, when you would be normally watching TV during the advert breaks, getting up and going to put your cup of tea down in the kitchen - moving for two minutes is stimulus enough to minimise negative health consequences.

My third year PhD student, Dale Grant found that even with that amount of what we call ‘non exercise intervention’ people build muscle and, surprising, bone strength and physical functional capacity - the ability to just get on with everyday activities - as well.

Over time, people report that they feel their range of motion is better and they improve their functional capacity better than people who do a single big block of exercise and then sit down to work.

Diet

If you're eating carbohydrates, you're then going to push yourself towards insulin dependence and towards a high level of cortisol, the body's main stress hormone.

It becomes a negative loop - you're more stressed, your body produces more cortisol, you don't sleep, and you want more carbohydrate.

If you didn't eat those carbohydrates that are no longer available in the shops (or at least not in my last two visits to the supermarket), you're pushing yourself out of that loop and into a healthier profile when you don't eat as much carbohydrate.

You're starting to work in your ketosis phase - when your body burns stored fat for energy - and it means you’re going to have a better inflammatory response, you're going to be more likely to be resistant to infections.

I would advise buying fatty fish – tinned salmon (especially the wild sourced type) or sardines in olive oil.

Not only are you getting your calories but Omega-3. I’d buy fresh green vegetable produce but also avocados, which is a fantastic vegetable in terms of the right fats for neuro-activation and decreasing inflammation, and making you insulin sensitive.

The nuts that are the best are macadamias, pecans, red-skinned peanuts, pistachio (the latter if you are not too worried about the carb content), and seeds such as chia, flax and pumpkin, which are all full of good fats.

I would particularly avoid sunflower, macadamia nut oil or rapeseed oil as their nutritional profile is not so helpful.

Just in case you do not have access to a lot of food (maybe because the supermarket shelves are empty or you do not have the storage capacity at home), I would advise buying nutritionally dense food rather than nutritionally empty foods, such as good quality peanut butter (not the kind that contains hydrogenated vegetable oils) or non-grain granola, because if I'm going to run out of food, I still need to know that with just a small amount I can pack enough calories to carry me through the day.

Vitamin C is important to help boost your immune system – it’s found in kiwi and citrus fruits - but to help your body absorb it, you need Vitamin D and so if possible, sit or walk for half-an-hour outside to expose yourself to the sun.

Alternatively, you can also get your vitamin D through some food such as the fatty fish mentioned above, but also mushrooms.
