Pregnancy is usually a time of happiness and hope, but it also brings in the unexpected. While there is much talk placed on the health of the expectant mother, the quality sperm coming from the father could dramatically change the outcome of pregnancy. The latest study suggests the risks of sperm DNA damage, even increasing the risks of complications preeclampsia and birth prematurity.

In a groundbreaking research study conducted by scientists from Lund University in Sweden, scientists discovered that DNA damage in sperm increases the risk almost up to double that of preeclampsia, this is a dangerous condition that may arise during pregnancies characterized by high blood pressure. In addition, DNA anomalies also increase the risk of premature births, and this further entails increased related adverse health outcomes for infants born through such conditions.

The next step would be to find out which group of men respond best to methods to prevent and treat sperm DNA damage, and to test these methods to prevent pregnancy complications," said Dr. Amelie Stenqvist, a lecturer at Lund University. According to this study, a significant message is put forward that paternal health assumes an important role in a successful pregnancy.

It focused its research on men, specifically whose sperm contained high levels of DNA fragmentation. For instance, some 20% to 30% of babies born via in vitro fertilization have fathers whose sperm contains damaged DNA. The DNA fragmentation index, an indicator to assess the percentage of DNA damage in sperm, indicated that when the percentage of sperm with a DFI above 30% was observed, they had almost no chance of resulting in natural conception. Even a DFI greater than 20% showed that the chances of getting pregnant are highly risky as the risk factor for pregnancy complications like preeclampsia is much high.

Uncommon Complications during Pregnancy

The most alarming complication during pregnancy is preeclampsia. It affects approximately 5% to 8% of pregnancies worldwide, which can cause fatal conditions for both the mother and the baby. The new findings now point out that sperm DNA damage may contribute to this condition, especially if it is due to assisted reproductive techniques such as IVF pregnancies. The research found that a DFI above 20% doubled the risk of preeclampsia from a mere 5% to almost 11% per.

Apart from causing preeclampsia, DNA fragmentation in sperm is also known to increase the risk for prematurity. Most premature babies experience respiratory, neurological, and developmental complications. Therefore, some degree of early intervention might be important for prospective parents.

Some of the rarer, though serious complications include placental abruption, which is the separation of the placenta from the uterine wall and intrauterine growth restriction, a condition by which the baby does not grow normally in the womb. These conditions though rare are potentially catastrophic both to the mother and the child. Results from this study may help in establishing the contribution of the father in such pregnancies.

Further study into sperm DNA damage is of urgent interest with regard to its consequences for pregnancy outcomes. According to Professor Aleksander Giwercman of Lund University in the field of Reproductive Medicine, "the analysis of DFI should be introduced as routine test in all fertility clinics.". "It could give answers to couples who are having difficulties with infertility, but our latest result also shows that DFI analysis can be a method to identify high-risk pregnancies, explained Giwercman.

For many, DNA fragmentation in sperm is often treatable. Common causes are oxidative stress, age, smoking, being obese, and infections. Addressing these elements will likely reduce DNA damage in sperm for men, raising the chances for a healthy pregnancy and baby.

Overall, the study importance should take into consideration paternal as well as maternal health towards reaching for a healthy pregnancy. Though DNA fragmentation in the sperm is supposed to increase the risk factors for complications in pregnancies, the advances into novel treatment approaches and tests are likely to alleviate complications in many families. Thus the findings of this study offer optimism and pave a pathway to more holistic fertility treatments in the future.

A 27-year-old woman in US' state of Arizona suffered a cardiac arrest after using kratom, an over-the-counter supplement she purchased at a local gas station.

Amanda Goodsell, who had never taken kratom before, suffered a cardiac arrest after nearly a week of using the supplement and is now on life support, according to her family.

The mother of 3½-year-old twins tried the kratom gummies at the suggestion of her husband, Mike Goodsell, while seeking relief from persistent leg pain.

“Everybody knew what Kratom was. So I was like, well, okay, well, here, just take this. You could just buy it at the gas station. It’s not going to hurt you,” Mike Goodsell was quoted as saying to the media.

Nearly a week later, Mike found his wife unresponsive in their bed, and rushed her to the hospital, where she was placed on life support

“She like, was like red and her lips were blue, and she was foaming. So I like jumped out of bed. I grabbed her, and then (I) was trying to wake her up,” he said.

“They had to have her on a ventilator to help her breathe. And then they had to put her on a bunch of medications because her heart percentage was at 15%,” Mike added.

After spending two weeks in the hospital, Amanda Goodsell's condition began to improve. Although she has shown significant improvement, as per the doctors she will need a defibrillator and heart medication for the rest of her life.

What Is Kratom?

Kratom is a plant-based substance derived from the Mitragyna speciosa tree, native to Southeast Asia. Traditionally used in countries such as Thailand and Malaysia for pain relief and increased energy, it has gained popularity in the US as an over-the-counter supplement.

Kratom is sold in multiple forms, including powders, capsules, teas, drinks and gummies.

Although it remains legal in many parts of the US, the Food and Drug Administration (FDA) has classified kratom as a "drug of concern" and has not approved it for any medical use.

According to the Substance Abuse and Mental Health Services Administration's National Survey on Drug Use and Health, an estimated 1.7 million Americans aged 12 and older used kratom in 2021.

The substance, sometimes referred to as "gas-station heroin," is banned in at least eight US states—Alabama, Arkansas, Connecticut, Indiana, Louisiana, Tennessee, Vermont and Wisconsin. Several other states, including Iowa and Idaho, are considering restrictions or outright bans.

Why Does The FDA Warn Against Kratom?

According to a University of Virginia study, there were 43 hospitalizations linked solely to kratom in 2015. By 2025, that number had risen to 538. Researchers said the increase coincided with the emergence of highly concentrated synthetic products, including 7-OH.

The FDA has stated that kratom should not be used as a dietary supplement.

"Kratom is not appropriate for use as a dietary supplement. FDA has concluded from available information, including scientific data, that kratom is a new dietary ingredient for which there is inadequate information to provide reasonable assurance that such ingredient does not present a significant or unreasonable risk of illness or injury."

The agency has warned consumers not to use kratom because of the risk of serious adverse events, including liver toxicity, seizures and substance use disorder (SUD).

The FDA also notes that, in rare cases, deaths have been associated with kratom use, although these cases usually involved other drugs and the contribution of kratom remains unclear.

The agency is also aware of cases involving neonatal abstinence syndrome, in which newborns experienced withdrawal symptoms such as jitteriness, irritability and muscle stiffness following prolonged exposure to kratom during pregnancy.

When it comes to climate change, we often visualise melting glaciers, rising sea levels, raging wildfires, or record-breaking heatwaves. But scientists are increasingly warning that climate change could also be silently affecting one of the body's most vital organs: the brain.

From rising mercury levels and worsening air pollution to floods, wildfires, and hurricanes, climate-related catastrophes are exposing millions of people across the world to conditions that could increase the risk of neurological disorders.

On World Brain Day, let's look at why brain health is another reason to take climate change seriously.

Effect Of Heatwaves On Brain Health

This can lead to poor concentration, slower reflexes, memory decline, headaches, confusion, and poor decision-making.

Older adults are particularly vulnerable because the brain's ability to regulate body temperature declines with age.

People living with neurological disorders like dementia, Parkinson's disease, multiple sclerosis, or epilepsy may also find that their symptoms worsen during periods of intense heat.

Effect Of Air Pollution On Brain Health

Climate change is worsening air pollution in many parts of the world by increasing wildfire smoke, ground-level ozone, and fine particulate matter.

These tiny pollutants, especially PM2.5, are small enough to enter the bloodstream and may even reach the brain. Studies have linked long-term exposure to air pollution with:

• Faster cognitive decline
• Memory impairment
• Increased risk of dementia
• Higher risk of stroke
• Parkinson's disease
• Poor brain development in children

Scientists believe air pollution may trigger chronic inflammation and oxidative stress, both of which can damage brain cells over time.

Effects Of Wildfires On Brain Health

While smoke affects the lungs, it can also impact the brain.

Wildfire smoke contains fine particles and toxic chemicals that have been associated with headaches, reduced attention, poorer cognitive performance, and increased emergency visits for neurological conditions.

People with existing neurological diseases may experience worsening symptoms during periods of heavy smoke exposure.

Extreme Weather Can Accelerate Brain Ageing

Climate change is also increasing the frequency and intensity of floods, hurricanes, droughts, and other natural disasters. Beyond physical injuries, these disasters can leave lasting effects on the brain and mental health. People affected by climate disasters often experience:

• Anxiety
• Depression
• Post-traumatic stress disorder (PTSD)
• Sleep disturbances
• Chronic stress

Children, older adults, and disaster survivors are among the groups most vulnerable to these long-term psychological effects.

How To Protect Your Brain?

While tackling climate change is a long-term strategic plan, individuals can maintain few self-care habits to reduce the risks. Experts recommend:

• Staying hydrated during heatwaves
• Avoiding outdoor activity during peak afternoon heat
• Monitoring local air quality before going outside
• Wearing a well-fitting mask during heavy wildfire smoke or severe pollution
• Keeping homes cool whenever possible

Brain health is often associated with old age, but according to neurologists, the foundation for healthy cognitive function is laid much earlier.

On World Brain Day, they warned that the 30s and 40s are a crucial period to protect the brain, as lifestyle habits and underlying health conditions can quietly affect memory, concentration, and overall cognitive health.

Brain Ages Alongside the Heart

Speaking to HealthandMe, Dr. Gurucharan Adoor, Neurologist, Apollo Hospitals Bannerghatta Road, Bengaluru, said brain health is closely linked to cardiovascular health. High blood pressure, high cholesterol, and elevated blood sugar can silently damage the brain years before noticeable symptoms appear.

His advice? Make preventive health checks a routine by monitoring blood pressure, blood glucose or HbA1c, cholesterol, weight, and waist circumference—especially for people with a family history of diabetes, stroke, or early heart disease.

Brain Fog A Warning Signal

Dr. Adoor said sleep is often the first thing people sacrifice during their busiest years, but the brain pays the price.

Irregular sleep schedules, untreated sleep apnea, and repeated nights of poor-quality sleep can lead to mental fatigue, difficulty concentrating, and persistent brain fog. If brain fog continues, he said, it should not be ignored, as it may indicate an underlying health issue that requires attention.

Dr. Bhushan Joshi, Consultant Neurologist, Manipal Hospital, Kharadi, Pune, told HealthandMe that he is "seeing more professionals in their 30s and 40s complaining of brain fog than ever before". According to him, hormonal changes and chronic inflammation are among the common but often overlooked causes.

Hormonal Changes Can Affect Cognitive Function

Dr. Joshi noted that hormonal fluctuations can significantly influence brain function. Women entering perimenopause may experience difficulty concentrating, while others may notice "word retrieval and short-term memory due to changing estrogen levels that influence brain function."

He added that it is not limited to women. Men also undergo age-related hormonal changes that can affect energy levels and cognitive performance. While these changes are often temporary, they can still be distressing.

Chronic Inflammation May Reduce Mental Clarity

Dr. Joshi explained that chronic low-grade inflammation can also contribute to brain fog. Conditions such as obesity, diabetes, autoimmune diseases, and persistent infections can trigger inflammatory responses that interfere with the brain's ability to process information efficiently. In some people, inflammation has been linked to reduced attention, poor memory, and diminished mental clarity.

Small Lifestyle Changes Key

The good news: Simple daily habits can support long-term brain health. Regular physical activity—whether it's walking, cycling, dancing, or strength training several times a week—improves blood flow to the brain, boosts mood, and supports healthy ageing.

Dr. Adoor also recommends limiting unnecessary screen time, taking regular breaks from phones and digital devices, and focusing on one task at a time to reduce mental overload.

When Should You See A Doctor?

Occasionally feeling mentally sluggish is common, but worsening memory problems or cognitive changes that begin interfering with work or daily life should not be ignored, Dr. Joshi said.

He added that these symptoms may stem from treatable conditions such as thyroid disorders, vitamin deficiencies, anxiety, or depression, making timely medical evaluation important.
