While there is no “cure” for COVID or its sequelae at this point in time, there are things that a person can do to promote the body’s own ability to heal and recover.
The role of rest is preeminent. Resting when tired and sleeping well at night. Sleep can be difficult to regulate. Set a reasonable goal, usually between six to eight hours of sleep, and discipline yourself to a set bedtime and wakeup time. For example, if you want to try for seven hours of sleep, first decide what time you want to get up, out-of-bed in the morning. So if you want to rise at 6:00 a.m., then you need to go to bed seven hours before that, 11:00 p.m. Set an alarm for 6:00 a.m. and get up when it goes off, even if you haven’t slept well that night, and don’t nap in the day or go to bed until 11:00 p.m., even if you are tired because you want to establish a good sleep habit. Avoid caffeine and alcohol in the evening, though you may try a gentle sleep aid at bedtime like melatonin or chamomile tea.
Pace your physical activities to your level of strength and endurance. You want to function to the degree of feeling tired, but not to the point of exhaustion. Pushing yourself to perform is healthy when it’s done to a level and duration that is just a little above what is comfortable. There is no sharp line that defines what this level is for everyone, but I like to say that you can push to the point of discomfort, but stop before the level of pain.
To help memory and concentration, exercise your mind just like you do your body. Reading, word puzzles, strategy games, learning a new skill are ways that you can exercise your mind. Just like your physical exercise, choose some activities that seem just a little difficult in order to stretch your mind.
