Gripp ja gripijärgne taastumine
The respiratory virus season is once again active in Estonia. Although infection rates may have temporarily decreased during the holidays and school breaks, influenza is on the rise again. Cases are occurring across all age groups, with particularly high numbers in areas with higher population density.
Many people recover from the flu within a few days — and that is great. However, for others, influenza does not end when the fever subsides, and that is why it is important to talk about flu complications and recovery.
Recovery from the flu can take time, especially after a more severe illness. The right recovery approach—including proper nutrition, gradual physical activity, and oxygen therapy, also known as hyperbaric oxygen therapy (HBOT)—can help the body heal faster and regain strength more effectively.

The flu is more than just a bad cold. Influenza can lead to a variety of complications, including:
- Pneumonia and respiratory infections
- Increased strain on the heart and circulatory system
- “Brain fog” and difficulty concentrating
- Prolonged fatigue and low energy
- Digestive issues (abdominal pain, digestive disturbances, irritable bowel-like symptoms)
- Slow overall recovery after a viral illness
It is often these post-viral conditions—situations where a person no longer feels fully like themselves after an illness—that drive people to seek additional recovery options and supportive therapies.
Why Recovery Can Take Time
After a viral illness, the body may be:
1
In an inflammatory state
If the body has been in a strong defense and healing mode during the flu, this state does not always subside immediately after the illness. The body continues repairing damaged tissues and maintains a heightened state of readiness for some time. This can lead to persistent fatigue, muscle aches, general weakness, and a longer recovery period.
2
Oxygen-deprived at the tissue level
If the body cannot efficiently transport oxygen due to the viral infection, cells temporarily go “hungry” for oxygen. This lack of oxygen slows recovery and may cause fatigue and muscle soreness.
3
Under oxidative stress
During post-flu recovery, the immune system remains active for a period, producing byproducts that can stress cells. If the body cannot neutralize these quickly, oxidative stress develops in the cells. This can disrupt normal cell function and energy metabolism, making recovery slower and prolonging fatigue.
Complications of the Flu and Post-Flu Recovery
After the flu, the body can remain in a prolonged state of recovery and balance-seeking, where healing processes, oxygen supply, and cellular function have not yet fully normalized. If the body stays in a mild inflammatory state, this can affect digestion, the nervous system, and overall energy levels, leading to digestive issues, headaches, or persistent fatigue. At the same time, insufficient oxygen delivery to tissues can disrupt normal cellular function, resulting in muscle weakness, brain fog, and a very slow recovery process.
During flu recovery, increased cellular workload and fatigue of the body’s defense systems can play a significant role. The body may become more vulnerable to various complications, and even minor issues can trigger stronger symptoms. The good news is that recovery and balance can be supported through targeted interventions that improve oxygen availability, support cellular function, and help alleviate post-flu discomfort.

Flu Recovery: Rest, Nutrition, and Physical Activity
Recovery from the flu and its complications often requires a multifaceted approach, as the illness can affect inflammation levels, tissue oxygenation, and normal cellular function. Recovery is best supported by adequate rest and the gradual increase of physical activity, allowing the body to restore balance without additional stress. Nutrition also plays a key role, providing essential nutrients and antioxidants while supporting digestive health and energy metabolism. In addition, targeted interventions that improve tissue oxygenation can further promote healing and support the body’s natural recovery processes.

One of those options is hyperbaric oxygen therapy (HBOT)which has been used to support various recovery and healing processes. During HBOT, a person breathes oxygen-rich air under increased pressure, allowing oxygen to dissolve more efficiently into the blood plasma and reach tissues where oxygen availability has been limited. This can support cellular energy metabolism, help the body exit prolonged inflammatory states, and promote tissue repair after a viral infection. Many clients at oxygen therapy centers have reported relief from post-flu symptoms after completing a course of hyperbaric therapy, including persistent fatigue, brain fog, muscle weakness, and digestive issues. While recovery is always individual and depends on multiple factors, HBOT can be a valuable part of a comprehensive approach to post-flu recovery.

Recovery from the flu is an individual process and can take time, especially after a more severe illness or when complications have occurred. Oxygen therapy can be a supportive part of a comprehensive recovery plan, helping to improve oxygen delivery, support cellular function, and alleviate post-flu symptoms. If you feel that your recovery is taking longer than expected, it may be worthwhile to explore additional options to support your body’s healing.
