Physical and Mental Long-Term Side Effects of COVID-19

COVID-19 can leave effects that last long after the initial infection clears — physically, in the form of fatigue, breathlessness, and cognitive difficulty, and mentally, in the form of anxiety, depression, and trauma-related symptoms. For some women, the emotional weight of a long illness becomes entangled with mental health and, at times, with substance use as a way to cope. If that's where you or someone you love has landed, our women's mental health treatment supports women navigating exactly this kind of overlap.

What Are the Long-Term Effects of COVID-19?

The long-term effects of COVID-19, often called long COVID, are symptoms and conditions that continue, return, or first appear after the acute infection has passed. According to the CDC, these symptoms can last months or even years, may involve many body systems, and can range from mild to genuinely disabling. Most people improve significantly within about three months, though for some the timeline stretches much longer, and symptoms can emerge, resolve, and reappear over time.

Long-Term Physical Effects

The physical effects of long COVID can touch nearly every organ system. The most consistently reported is profound fatigue — not ordinary tiredness, but exhaustion that doesn't lift with rest and can worsen after exertion. Peer-reviewed reviews have found fatigue persisting in roughly a third of people studied, often alongside shortness of breath, chest pain, and disrupted sleep many months after infection.

Common Physical Symptoms

• Persistent fatigue and post-exertional crashes
• Shortness of breath
• Chest pain and heart-rate changes
• Sleep disruption
• Multi-organ effects after severe illness, involving the heart, lungs, kidneys, skin, or brain (CDC)

The CDC notes that people who had severe COVID-19, especially those hospitalized, may experience multi-organ effects or autoimmune conditions lasting months or longer. The unpredictability — symptoms that come and go without clear cause — is itself part of what makes long COVID hard to live with.

Long-Term Mental and Cognitive Effects

The mental and cognitive toll of long COVID is significant and increasingly well-documented. Cognitive difficulty — widely described as 'brain fog' — affects memory, concentration, and mental clarity in ways that can disrupt work and daily life. A 2025 meta-analysis found cognitive, memory, or attention difficulty in about 36% of people with long COVID, and mental health problems including anxiety and depression in about 31%.

Mental health effects aren't only a reaction to feeling unwell; research increasingly treats them as part of the condition itself. One community-based study found long COVID associated with measurable increases in depression, anxiety, suicidal ideation, and PTSD symptoms compared with people who didn't have it. A separate review noted that, in order of prevalence, the most common psychiatric symptoms were anxiety, depression, PTSD, poor sleep, and cognitive deficits.

There's also a recursive quality to it: physical limitation feeds low mood and anxiety, which in turn make the physical symptoms harder to cope with. Researchers describe this as a downward spiral linking physical health, mental health, and daily functioning — which is part of why support matters before things compound.

Why Women May Face Added Risk

Research on the psychiatric effects of long COVID identifies two notable risk factors: being female and having a previous psychiatric diagnosis. For a woman already managing anxiety, depression, or trauma, a long illness can intensify what was already there rather than introduce something entirely new. That's part of why a women-centered, trauma-informed approach to recovery is well-suited to this kind of overlap.

When Long COVID, Mental Health, and Substance Use Overlap

Chronic illness, isolation, and ongoing emotional distress can each raise the risk of turning to alcohol or other substances to cope. Research during the pandemic found meaningful shares of people increasing substance use to manage stress, and studies of long-COVID 'long haulers' have examined the link between their psychiatric symptoms and substance use. When the use that started as coping tips into dependence, it deserves real support rather than shame.

Anchored Tides treats co-occurring mental health and substance use together. For a woman whose anxiety or depression has deepened through a long illness, and whose drinking or substance use has quietly crept up alongside it, our dual diagnosis treatment addresses both at the same time, because treating only one tends to leave the other to undo the progress.

When to Seek Help

Persistent physical symptoms after COVID-19 are a reason to talk with a medical provider, who can evaluate and support you. Persistent low mood, anxiety, hopelessness, or a growing reliance on substances to cope are reasons to reach for mental health support. You don't have to wait until things feel unbearable to ask for help — earlier is almost always easier than later.
