Maybe you've struggled to keep your focus, or feel like you're walking in a daze. The good news is you are not alone and there’s a name for this feeling: brain fog. 

Brain fog can show up in a variety of ways. You might be unable to concentrate for long enough — on work tasks, conversations, or even on the words you’re reading right now. You may have difficulty making up your mind, small decisions are a big deal, you need more coffee to focus, more snacks to stay awake, and more booze at night for temporary relief from the fog. In more severe cases, you might have headaches, problems with your vision or even nausea.

In addition to direct effects on the brain, COVID-19 can also have long-term effects on other organ systems. So-called long haulers can have other lingering symptoms including fatigue, body aches, inability to exercise, headache, and difficulty sleeping. Some of these problems may be due to damage to their lungs, heart, kidneys, or other organs. Damage to these organs — or even just the symptoms by themselves — can impair thinking and memory and cause brain fog.

COVID-19除了对大脑的直接影响外，还会对其他器官系统产生长期影响。一些挥之不去的症状，包括疲劳、身体疼痛、无法运动、头痛和睡眠困难，可能是由肺、心脏、肾脏或其他器官的损伤造成的。对这些器官的损害同时也会损伤思维和记忆力，从而导致“脑雾”。

Stick to a healthy diet — mostly vegetables, enough protein, and always some good fats. Get plenty of omega-3 fatty acids (for their anti-inflammatory powers), a lot of antioxidants and coenzyme Q10 (essential for energy), and boost your body’s natural energy production and regeneration with essential vitamins and minerals.

Cognitive abilities decrease with sleep deprivation. Sleep is a time when the brain and body can clear out toxins and work toward healing. Make sure you give your body the sleep it needs. Sleep at least seven hours nightly, preferably eight or even nine when possible.
