A quick informal Google search shows that the most relevant sites to the question “How do people feel during the covid-19 pandemic?” relate to people’s mental health, with stress, anxiety and depression listed as common concerns. So how do we practice some healthy lifestyle habits to manage stress in the middle of a global pandemic? In this webinar, PERFORM Centre’s Christina Weiss and Théa Demmers share some strategies related to being active and eating well.
Théa is a licensed dietitian with the Ordre professionnel des diététistes du Québec (OPDQ) and Dietitians of Canada . Théa supervises and supports the activities in the Nutrition Suite at the PERFORM Centre, and hosts dietetic interns and graduate students.
Théa has worked previously with various community organizations, and as an instructor in Concordia’s Department of Health, Kinesiology and Applied Physiology. She has experience with interactive workshops, talks, cooking workshops and nutrition counseling for: diabetes (gestational, Type 1 and Type 2), weight management, eating disorders, food allergies or gastrointestinal conditions, mental health conditions, nutrition for exercise, across the lifespan, renal failure and oncology. Théa also has experience in recipe and menu development.

Christina is a clinical exercise physiologist who is specially trained to work with special populations that include medical high-risk and chronic illness population, such as people with disabilities, arthritis, and other related conditions that reduce and limit mobility, with a specialization in adapted physical activity.
Christina primarily oversees all programming related to the PERFORM Centre Conditioning Floor. She also coordinates the CEP, (Clinical Exercise Physiology), internship, apprentice and volunteer programs on the Conditioning Floor.

Questions answered offline:
Melodee: It’s expected that the coronavirus pandemic causes a sense of loss of normalcy and insomnia due to loss of control, worry and anxiety. Furthermore, it’s tempting to oversleep even if you are working from home without a specific start/end time. My suggestions would be as follows:
By doing this, it will not only result in improved sleep due to better sleep hygiene but will also restore your sense of control.
Théa: Meal preparation of many meals on one day per week can be a strategy. However, research suggests that we do what we can sustain and enjoy. In terms of habits and goals, research suggests choosing 1-3 things max. to work on at a time. While we don’t have specifics for number of meals to make during the week, I interpret the research on habits to choose 2 items to make during a meal prep day, and I make enough portions to use during several days of the week (2-4 days). So I make usually a soup and either a casserole or meal that can be stretched to make leftovers. This covers us for lunches for half the week, and at least 2-3 suppers. I then have a few easy go-to meals for the remaining two week days and on the weekends, we enjoy preparing other meals that we eat each day. For breakfast, I choose easy items, like whole-grain cereal (oats or other bought cereals), bread (I am lucky and have a bread machine so I spend 5 minutes a week making a loaf), and on the weekends we rotate and make either pancakes, waffles, crêpes, muffins, and eggs.
Christina: Yes, it can. It depends on the intensity. Exercise is a stressor on the body and thus it releases stress hormones such as epinephrine and cortisol that increase sugars and fats into our system. The higher the intensity, the higher the concentration of those hormones. Our body uses sugars and fats during exercise and then stores them during rest. These sugars and fats give us energy and can make it difficult to sleep. Physical activity increases endorphins in our blood. These are mood-enhancing hormones. For example, serotonin increases during exercise and can sometimes make us feel too good to sleep. Exercise increases blood circulation and increase oxygen in our brain, which can stimulate the brain to give us great ideas right when we are ready to sleep. Yoga and meditation or another exercise at a light intensity may help you sleep and calm you from the emotions of the day. Perhaps wait 1-2 hours after moderate to vigorous exercise before going to bed. Play with different types of exercise prior to sleep to find which one helps you sleep better.
Melodee: The research is mixed on this topic. It may depend on the individual’s fitness level (and the intensity of the exercise routine). Some researchers have reported that high intensity exercise close to bedtime results in sleep disruption.
Théa: Of course, it's all a matter of how often and how much. A strategy can be to choose when you want to enjoy these and use smaller packages so that you do not have large quantities visible and accessible, as we all eat what is simple and most readily available.
Théa: This could vary for each person according to your experience with any stomach upset. It also depends on what you eat, in general if you have foods that contain carbohydrate, like fruits or grains, these are lower in protein and very easily digested. It is actually recommended to consume a carbohydrate rich snack before exercise to reduce fatigue, inflammation and risk of injury if you haven’t eaten a meal in 2-3 hrs before your HIIT session. If you ate a meal with protein foods (meat, poultry, eggs, dairy, legumes, nuts or seeds, fish or seafood), this will take longer to digest and it is best to delay exercise 30 min. or more to avoid stomach upset, depending on each person’s individual experience and comfort.
Christina: It depends. Testing guidelines recommend waiting 3 hours. The American College of Sports Medicine (ACSM) recommends waiting for 1-3 hours before maximal or high intensity exercise, depending on your digestive system, to prevent gastrointestinal discomfort. However, not every person digests the same way. If you are going to eat something prior to waiting 3 hours, eat easily digestible carbohydrates such as whole grains, low-fat or fat-free yogurt, fruit, and vegetables. It takes a while to learn what your digestive system will tolerate. It usually requires a bit of trial and error.
Théa: In studies looking at nutrition and behaviour, people who eat foods that contain very little protein and mainly sugar report feeling more sleepy over time (and if the context of eating the sweet item does not have associations that make people more alert, e.g. think carnivals and cotton candy etc.). This is because the sugar can influence the production of serotonin in the brain, which can make us feel sleepy. However, this only occurs if there is no protein eaten, as this favours the transfer of the protein building blocks (i.e. amino acids) circulating in our blood to the brain that are precursors for serotonin. However, eating foods concentrated in sugar, with minimal protein is not recommended as a long-term strategy for health.
For shift workers and those who work on the road, it is recommended to maintain a routine, eating the main meal as early in the day as possible and before work and to avoid eating too much during the night, packing healthy snacks, limiting caffeine, alcohol, fatty or sugary foods and drinks.
I am not familiar with any research studies evaluating the “jet-lag” or Extreme Argonne CIA version diet, comprised of fasting, avoiding caffeine and alcohol, and eating your first meal according to the time-zone of your destination.
