Winter is here, which means the season of sickness too is here. While viruses and sickness run throughout, winter is when the chilly weather further makes it worse for those prone to sickness. Especially, if they are kids, as their immunity is not fully developed.

Does that mean it is inevitable for kids to be sick?

Anytime a child is exposed to another child, they will fall sick. This is because germs are transferred in the air or by touch, and children, being curious, always touch things, including their own faces, mouths and easily pick up germs and spread them. While prevention is impossible, there are steps that can be taken to reduce this.

Experts and medical professionals recommend to follow the vaccine schedule by the Centers for Disease Control (CDC) and American Academy of Pediatrics (AAP). Vaccines have be proven to protect people, children, and infants from serious and deadly infections.

While sicknesses like a common cold do not have a vaccine, good hygiene can help prevent the spread of germs. Teaching your kids to wash hands after touching toys, or any other surface and other people is a great way to start it.

Exposure to germs at an early age strengthens child's immune system

Is there really any truth in the statement? When we encounter infections, our immune system creates antibodies that either prevent future infections or help the body fight them off more effectively, often leading to milder illness. The "hygiene hypothesis" proposes that living in an overly clean environment might hinder the immune system's development, potentially increasing the risk of allergic conditions like asthma.

Although research has explored this idea, many immunologists (experts in the immune system) have raised concerns and expressed disagreement with the hypothesis.

In reality, most children don’t grow up in sterile environments. They are naturally exposed to a variety of germs, providing ample opportunities for their immune systems to strengthen and adapt.

Sanitizing Child's Toys

It is a good practice to regularly disinfect your children's toys and anything they share with others or take to school.

It is important to know the difference between cleaning, sanitizing, and disinfecting. While cleaning removes visible dirt, sanitizing decreases the number of germs on the surface, whereas disinfecting kills germs.

Also make sure to read the labels correctly and prevent any toxic toys to make its way to your kids, so it cannot be inhaled or ingested.

How to disinfect toys?

You can start by cleaning all the toys that has come in contact with your child's hands and mouth with soap and water. Then, use a sanitizer to clean everyday items, things that remain in your child's environment. Then use disinfectant, especially if your child is sick or if someone sick has touched your child's toys.

If you are wondering which sanitizers to go for, the Environmental Protection Agency (EPA) website has come up with a list of approved sanitizers and disinfectants that are effective.

Model and entrepreneur Hailey Bieber recently opened up about her postpartum journey, shifting focus on one of the least-discussed aspects of women’s health: premenstrual dysphoric disorder (PMDD).

Hailey said that she experienced PMDD after the birth of her son, Jack Blues Bieber. It is a menstrual health condition that can cause intense emotional and physical symptoms.

In an interview with Women's Wear Daily, Bieber spoke about how motherhood drew her towards women's health, especially considering the challenges she faced after childbirth.

"After I had my son, I struggled with [PMDD] a bit, and there's just not a lot of conversation or research around it," she said.

Bieber, who welcomed her son with husband Justin Bieber in August 2024, had previously discussed her diagnosis during an appearance on the SHE MD podcast in March 2026. She said she was diagnosed approximately six months after giving birth.

Although she had experienced premenstrual syndrome (PMS) before pregnancy, she noticed that the emotional symptoms leading up to her period had become much more intense.

"I was like, 'This just feels way more intense than before,' like, the lead-up to getting your period," she said.

She said she experienced overwhelming emotions, adding, “Why does it feel like my whole entire life is gonna end? Like, I don't understand.”

Bieber said her symptoms gradually improved over time. She also highlighted how speaking about her experience helped her feel less isolated. "Conversation, for me personally, makes me feel less alone," she said.

Premenstrual dysphoric disorder is a severe form of premenstrual syndrome (PMS) that causes intense emotional, mental and physical symptoms during the days leading up to menstruation.

Symptoms usually surface one to two weeks before a period and improve within a few days after menstruation starts.

Unlike premenstrual syndrome, PMDD can significantly interfere with a person's ability to work, relationships, social life and other daily activities. According to the UK's National Health Service (NHS), common symptoms include:

• Severe anxiety, tension or feelings of hopelessness
• Depression, sadness or mood swings
• Intense irritability or anger
• Feeling overwhelmed or out of control
• Reduced interest in everyday activities
• Difficulty concentrating
• Fatigue and sleep disturbances
• Breast tenderness, bloating and muscle or joint pain
• Changes in appetite and food cravings

Some women may also experience suicidal thoughts, which makes it important to recognise the condition and seek medical help promptly.

PMS and PMDD are both caused due to hormonal changes in the menstrual cycle. However, the intensity of symptoms and their effects on daily life distinguish the two conditions.

PMS can cause physical and emotional discomfort like bloating, tender breasts, headaches, food cravings, irritability and mood swings in the days leading up to menstruation.

PMDD symptoms can be more severe, especially depression, anxiety, irritability and emotional distress. These symptoms can disrupt work, relationships and everyday functioning.

PMDD is not just an extreme version of a bad premenstrual week. It is a recognised health condition that may require medical treatment.

Why Does PMDD Happen?

Experts say that the exact cause of PMDD is not fully understood yet. But they believe it may be due to an increased sensitivity to normal hormonal changes during the menstrual cycle.

After ovulation, levels of hormones like oestrogen and progesterone fluctuate. In some individuals, the brain may respond differently to these hormonal changes, affecting mood regulation and other bodily functions. Serotonin, a neurotransmitter involved in regulating mood, sleep and appetite, may also play a role.

Hailey Bieber's experience has sparked conversation about PMDD risk after childbirth. Pregnancy, childbirth and the postpartum period involve significant hormonal and physical changes.

However, PMDD is linked to the menstrual cycle and its recurring hormonal fluctuations. The return of menstrual cycles after childbirth may make premenstrual symptoms intense. However, there is limited evidence establishing that childbirth directly causes PMDD.

PMDD should also not be confused with postpartum depression. Postpartum depression can occur after childbirth and is not restricted to the days before menstruation. PMDD follows a recurring pattern linked to the menstrual cycle. Its symptoms may generally ease after the period begins.

Men are beginning to discuss fertility preservation, but the concept of freezing sperm before the age of 35 should not be promoted as something that all young men should undergo. There is no consensus on when men should freeze their sperm; rather, it will depend on their 'personal choice for future childbearing, medical risk, the quality of their sperm and whether, and when, they would be willing to pursue medical assistance or face new circumstances that may limit their options'.

Age still plays a role because male fertility is not entirely age-independent either. Although spermatogenesis persists with age, a prolongation of paternal age is associated with a gradual deterioration in semen parameters and sperm DNA.

How Age Affects Sperm Quality And DNA

A recent 2024 study of 200 turgescent samples from normozoospermic males aged 35 years or less demonstrated DNA fragmentation of 15.

4% in patients of 35 years or less versus 21.7% in patients of 42 years or more. In the older group, host freezing was linked with an increased DNA fragmentation index to 26.7%. This is the reason why sperm freezing upon retrieval at a younger age may have biological benefits.

But the biggest reason for sperm banking is still fertility preservation related medical issues. Men who are diagnosed with testicular cancer, lymphoma, leukaemia or other cancers should ideally freeze sperm before the commencement of chemotherapy, radiotherapy, or possibly fertility-damaging operations and surgery. The 2025 ASCO guideline explicitly urges that fertility preservation be taken into consideration and sperm banking made accessible before cancer therapy.

Medical Conditions And Treatments That Can Affect Male Fertility

Men diagnosed with health conditions, receiving medical treatment, or taking drugs that could affect sperm production could also be eligible. Autoimmune diseases, certain systemic diseases, and certain medicines have been reported to interfere with normal sperm production. If testosterone treatment is on a man's agenda, then he should also talk about sperm preservation as a possible option since externally applied testosterone therapy can suppress the body's naturally occurring testosterone levels and, because of this, impair the production of sperm.

Sperm freezing may also be particularly relevant for men with persistently low sperm count or poor sperm motility, especially when these findings are accompanied by elevated follicle-stimulating hormone (FSH) levels. High FSH can indicate impaired testicular function and reduced sperm-producing capacity.

In some men, sperm production may decline further over time, and in severe cases, sperm may become very few or even difficult to retrieve from the ejaculate. Banking sperm when viable sperm are available can therefore provide an additional option for future fertility treatment. The decision should be individualised based on semen parameters, FSH levels, the underlying cause and the advice of a reproductive urologist or fertility specialist.

Elective Sperm Freezing For Men Delaying Parenthood

Men who expect to delay parenthood are also showing interest in so-called "elective" or "social" sperm freezing, which is done when it's not related to any medical condition or infertility. It would be the right choice mostly for those men who would not be able or are not sure to get married or to have kids soon, who are exposed to occupational factors endangering fertility, or who want to have a medical treatment that might negatively affect their fertility.

A major 2025 registry analyzing 7,044 men undergoing sperm bank over 30 years indicated an average age at cryopreservation of around 33.1 years, whereas those between 3540 were among the ones most often coming back to take their samples from the freezer.

Importantly, freezing sperm is not the same as guaranteeing a future baby. A 2023 study of 7,969 donor-oocyte cycles found broadly comparable outcomes using fresh and cryopreserved sperm, although fertilisation was marginally lower with frozen sperm after adjustment, 73.66% versus 74.65%.

So, before 35, sperm freezing is best viewed as an option for selected men, not a compulsory fertility insurance policy. Anyone considering it should first undergo a semen analysis and counselling with a reproductive urologist or fertility specialist, particularly if there is a medical, genetic or reproductive risk.

With infertility affecting an estimated one in six couples, experts at the Times Network India Health Summit 2026 spoke about the importance of seeking timely reproductive health advice and acquiring awareness about treatment options.

They discussed how advancements in fertility treatment have improved the chances of conception, but in vitro fertilisation (IVF) cannot guarantee a pregnancy.

During a panel discussion titled “The Fertility Revolution: Reimagining Parenthood in Modern India,” experts also examined how technology is shaping fertility care, while focusing on the limits of treatment, the cost of repeated IVF cycles and the dire need to address stigma around infertility.

IVF Is A Ray Of Hope For Many Couples But Not A Guarantee

Dr. Hrishikesh Pai, Founder and Managing Director of Bloom IVF India, spoke about the improvement in IVF outcomes over the past three decades. “When I started my own area in 1990, the success rate was 5%. Now it has gone to 30%,” he said.

Pai also spoke about the expansion of India's fertility treatment sector, saying the country had moved from an emerging field to one with centres capable of matching international units in performance.

Technology is also fueling more possibilities in reproductive treatment. Pai discussed the use of artificial intelligence (AI) to assist with embryo selection, egg assessment and sperm identification, alongside emerging techniques like robotic-assisted microinjection.

However, Dr. Abha Majumdar, Emeritus Consultant in IVF and Human Reproduction at Sir Ganga Ram Hospital, cautioned against allowing these advances and spoke about the importance of maintaining unrealistic expectations.

“IVF is not a miracle,” she said, emphasising that patients should receive accurate information about likely outcomes and the limitations of treatment.

Majumdar also raised concerns about AI-generated advertisements promising successful IVF cycles. She stressed that technological progress does not remove the responsibility to communicate treatment outcomes honestly and compassionately.

For couples considering parenthood later in life, understanding age-related fertility decline is important. Dr. Ranjana Sharma, Senior Consultant in Obstetrics and Gynaecology at Indraprastha Apollo Hospital, explained that women are born with a finite supply of eggs, which declines over time.

She highlighted the need for greater awareness of reproductive timing and the options available to people who plan to delay pregnancy.

Majumdar also discussed reproductive autonomy, noting that women increasingly have the freedom to decide when, or whether, to have children. However, she cautioned against viewing egg freezing as a guarantee of future pregnancy, describing it instead as a form of insurance.

Fertility preservation may also be relevant for people facing medical treatments that could affect their reproductive potential. Pai highlighted egg freezing before chemotherapy or radiation therapy as an option for some women who wish to preserve the possibility of having children later.

Sperm freezing can similarly help some men preserve fertility before cancer treatment or in circumstances where future fertility may be a concern.

Even when treatment is available, its cost can be anobstacle. Some patients require more than one IVF cycle, making the overall expense staggering.

Majumdar warned that repeated treatment can become expensive for some families. Although access to fertility services and insurance coverage have improved, affordability remains an important concern.

She also emphasised that patients need realistic information before beginning treatment, including an understanding that one cycle may not result in pregnancy.

Dr. Vimal Grover, who spoke about rising infertility and changing reproductive patterns, identified delayed marriage and childbearing, along with work-related stress, among the factors she had observed. She also pointed to AI's potential role in transforming fertility care.

“One in six couples is infertile,” Grover said. The figure highlights the scale of the infertility crisis in the country.

Male Infertility Remains Overlooked

The panel also addressed the tendency to blame women when couples experience difficulty conceiving. Sharma said women are often held responsible for infertility, even though reproductive difficulties can involve either partner. She also said that fertility specialists increasingly make a point of consulting both partners to encourage shared responsibility for getting tested and treated.

Pai similarly emphasised the importance of evaluating male fertility. Alongside sperm freezing before chemotherapy or radiation therapy, he highlighted its relevance for men with low sperm counts and some patients who may need fertility treatment in the future.

The experts urged couples experiencing difficulties conceiving to seek medical advice rather than feel ashamed or assume that infertility is solely a woman's concern.

The panel was part of the Times Network India Health Summit 2026, held in New Delhi under the theme “The Blueprint for a Future-Ready Healthcare Ecosystem – Innovation. Access. Self-Reliance.” The summit brought together healthcare leaders, clinicians, researchers, policymakers and industry stakeholders to discuss the future of India's healthcare system.
