On Monday night, a magnitude 6.6 earthquake struck Japan, leading to a tsunami warning. Fortunately, authorities reported minimal damage, and the warning was soon lifted. According to local media, there was only one minor injury involving a man who fell at his own home.

Japan, located in the Pacific Ring of Fire, experiences approximately 1,500 tremors annually. However, these quakes have a long-lasting impact on one's health—both physical and mental.

Health Impacts Of Earthquakes

1. Wound Infections

Earthquake-related injuries range from cuts and bruises to fractures and crush injuries. If not attended to on time, these wounds can lead to infections like sepsis, tetanus, or even amputations if untreated. Regions with scarce medical resources face higher risks of untreated injuries and antimicrobial resistance. Ensuring prompt medical care and deploying teams to assess building safety is critical to preventing further injuries and fatalities.

A recent study examined infections in 225 earthquake survivors with musculoskeletal injuries treated between February and April 2023. It found that gram-negative bacteria were common in the wounds of the victims. Acinetobacter baumannii (49.4%) and enterococci (28.6%) were the most prevalent. Many pathogens were multidrug-resistant, with 76% from wound cultures and 58% from deep tissue cultures showing resistance. Common infections included surgical site infections (32.8%), urinary tract infections (5.3%), bloodstream infections (5.7%), and pneumonia (0.4%). Intensive care was required for 35.6% of patients, with a mortality rate of 2.7%.

2. Infectious Diseases

Earthquakes disrupt water supplies, leading to unsanitary conditions that spread waterborne diseases such as cholera. Meanwhile, it also pushes people to take shelters in dingy places, which can outbreaks of measles, respiratory illnesses, and parasitic infections like leishmaniasis. Cold conditions and stress suppress immunity, increasing the risk of disease spread.

3. Chronic Conditions

Access to medication and medical care is often disrupted by earthquakes. Studies show increased rates of heart attacks, strokes, and diabetes following earthquakes due to stress and disrupted routines. Destruction of health records and facilities exacerbates these issues, especially in disaster-prone regions.

4. Healthcare Disruption

Damaged medical facilities and transport links hinder healthcare delivery. Pregnant women and individuals with chronic diseases face heightened risks. Refugees and displaced populations encounter accessibility barriers to healthcare services.

5. Psychological Trauma

Survivors of these earthquakes often suffer from anxiety, depression, and Post Traumatic Stress Disorder (PTSD). Tailored mental health programs are crucial for recovery, especially for those already living in conflict zones or displacement.

On April 14 2010, a 7.1-magnitude earthquake struck Qinghai Province, China, devastating Yushu County. A psychological relief study, published in the Journal Of Affective Disorders in 2011, assessed the mental health of 505 survivors three to four months post-disaster. Using tools like the PTSD Checklist-Civilian version (PCL-C) and Hopkins Symptoms Checklist-25 (HSCL-25), the study found prevalence rates of 33.7% for probable PTSD, 43.8% for anxiety, and 38.6% for depression, with one-fifth of participants experiencing all three. Key risk factors included being female, experiencing intense fear during the quake, and having limited social support, as measured by the Perceived Social Support Scale (PSSS).

Hypertension, or high blood pressure, is caused by excessive salt intake; however, according to scientists, there are more reasons. Experts also blame a brain glitch. A part of the brain that makes us breathe while laughing or coughing could also cause a blood pressure spike, as per researchers from New Zealand and Brazil. This could explain why medication is not enough for controlling BP in some people. According to experts at the University of Auckland, there is a part of the brain that could cause high BP, thereby suggesting that the brain is responsible for hypertension.

Is the brain responsible for high BP?

Experts say that the lateral parafacial region is located in the brainstem. It is the oldest part of the brain and regulates heart rate, digestion, and breathing. Its action causes one to exhale during a cough, laugh, or workout. These actions are driven by abdominal muscles. Researchers also found that this area could connect to the nerves that tighten blood vessels and raise blood pressure. However, it is possible to reverse this action by inactivating this region.

What is hypertension?

Hypertension, or high blood pressure, is a condition wherein blood pushes against the walls of the blood vessels with too much force. Initially, it has no symptoms, but it is a silent killer. Over time, untreated high BP can lead to a stroke or a heart attack. While it is mostly believed to be a consequence of smoking, drinking alcohol, eating salty foods, and not exercising, experts have found other causes as well. As per research by the University of São Paulo in Brazil and the University of Auckland in New Zealand, published in the journal Circulation Research, rat brains had their brain cells in the lateral parafacial region switched off.

How is high BP triggered by the brain?

Researchers in the study successfully reactivated neurons in some rats and found that brain circuits ultimately raised BP. Experts mapped out what happened and compared it with rats that did not have hypertension. In the hypertensive group, lateral parafacial region neurons were helping with breathing but were also raising BP. This suggests that changes in breathing, which involve abdominal muscle contractions, can also trigger high BP. This is why patients with sleep apnoea experience interrupted breathing while sleeping and high blood pressure.

Apart from normal breathing, lateral parafacial region neurons are activated when oxygen levels are low. Experts also checked whether they could trigger the brainstem with medication. They noted that it was tricky because drugs would work on the entire brain and not a specific region. It could be activated by signals from the neck cells near the carotid artery. These can be safely targeted with medication.

How to control persistent high BP?

To control persistent high BP, medication every day is a must. But to intensify the benefits, try the following simple tricks:

1. Reduce salt intake
2. Meditation
3. Quit smoking
4. Lose weight
5. Limit alcohol intake

We live in a world where the option of not turning to medication is almost non-existent. While once issues like fatigue and body aches were restricted to the elderly, it has now started to appear in youngsters as well. Many people depend on drugs for immediate relief in today's fast-paced world. Medication can help, but the best way to stay healthy is to make beneficial habits every day. But according to Dr. Mandeep Singh Basu, Director of Mirasa Ayurveda, there are some small, regular changes that can be made to your lifestyle for quicker healing, balance, and better immunity. You may start making five simple yet effective adjustments right away.

Medicine-free ways to feel energetic

1. Eat Fresh, Balanced, and Natural Foods: Your diet has a big effect on your overall health. Instead of processed and junk foods, eat fresh fruits, vegetables, nutritious whole grains, and meals you make at home. A balanced diet helps your body fight off sickness naturally, boosts your energy levels, and assists with digestion. It's just as crucial to eat on time and avoid overeating.
2. Make sure you get enough sleep: Your body repairs itself as you sleep. Stress, a weak immune system, weight gain, and lifestyle-related problems can all happen if you don't get enough sleep. Get 7-8 hours of uninterrupted sleep every day. Creating a regular sleep routine as well as limiting time spent on electronic devices prior to bedtime would significantly help improve your sleep quality.
3. Stay Physically Active: Regular physical activity benefits both your body and your mind. You don't have to spend hours working out to notice benefits. Simple things like walking, doing yoga, or stretching will help a lot. Daily exercise naturally increases blood flow, speeds up metabolism, and helps control diabetes and high blood pressure.
4. Manage Stress Effectively: Long-lasting stress is one of the key contributors to multiple health issues. Stress that lasts long will negatively affect your heart, digestion, quality of sleep, and eyesight. Incorporate relaxation techniques such as yoga, meditation, deep breathing, and mindfulness into your daily lives. You can also help relieve stress by getting outside into nature or performing hobbies.
5. Cleanse your body in a natural way: Your body naturally removes toxins, but unhealthy habits might slow the process down. If you drink enough water, eat foods high in fiber, and live a healthy life, your body starts to detox in a better way. Drinking warm water or herbal tea first thing in the morning is a simple thing you can do to aid your digestion and your health in general.

By adopting a mindful way of living, you may greatly enhance your physical, mental, and emotional well-being without having to rely on medication. You may also achieve full health and wellness by making relatively simple adjustments to how you live your life every day.

Vaccination has been the most powerful and effective tool in modern medicine that improves the body's immune system and fights off diseases, saving millions of lives annually.

Vaccines reduce the risk of getting a disease by working with your body’s natural defenses to build protection. Vaccines are available to prevent more than 30 life-threatening diseases and infections, helping people of all ages live longer, healthier lives.

According to the World Health Organization (WHO), immunization currently prevents 3.5 million to 5 million deaths every year from diseases like diphtheria, tetanus, pertussis (whooping cough), influenza, and measles.

While vaccines are available for both young and old, former director of AIIMS New Delhi, Dr Randeep Guleria, in a post on social media platform Instagram, urged doctors to recommend these based on people's age and the presence of comorbidities.

“Two very important factors one has to consider when recommending a vaccine for the adult population. One is the age, and if you have a patient over the age of 60 years, vaccination is definitely something you should recommend, or if a patient has associated comorbidities which increase the chance of vaccine-preventable diseases,” said the noted pulmonologist from Medanta Hospitals, Gurugram, in a Doctor's Special Series.

He recommended doctors to prescribe six types of vaccines for adults, namely:

• Influenza Vaccine

“It can be given as a pre-winter vaccine, which is a northern hemisphere vaccine, or it can be given in May or June when it is a southern hemisphere vaccine,” he added.

A flu vaccine typically reduces the risk of influenza infection, prevents severe illness, and complications.

• Pneumococcal Vaccine

“For the pneumococcal vaccine, we now have a conjugate vaccine, which is available as PCV20, which is once in a lifetime, and that has made things much more easier,” Dr. Guleria said.

The PCV20 vaccine guards against 20 strains of pneumococcal bacteria. It also prevents serious pneumonia, invasive infections, and related complications. It is recommended for adults aged over 65 and those with weakened immune systems.

• Shingles Vaccine

The vaccine against shingles prevents the risk of viral infection that causes a painful rash and nerve damage. It also helps prevent long-term nerve pain and prevents serious complications from shingles. The vaccine is safe for adults 50 and older.

• Tdap vaccine

The Tdap vaccine protects against pertussis infection, also known as whooping cough. It guards against tetanus infections and reduces the risk of diphtheria and related complications.

• HPV vaccine

Beyond cervical cancer, the HPV vaccine also protects against anal and throat cancer. It prevents 90 percent of HPV-related cancers, is safe, and effective. It also prevents genital warts.
