Kids love going around places, playing, and exploring new things. While all of this is fun, it can expose them to diseases. When they come from school, they are exposed to various germs through air and transmission or direct contact. They also touch surfaces a lot, then their face, then their mouths. This makes it easy for illness to spread. While it is impossible to prevent illness completely, there could be several measures that can reduce the risk and support recovery.

Vaccination

Vaccination is a critical step in preventing severe illnesses. The Centers for Disease Control and Prevention (CDC) and the American Academy of Pediatrics (AAP) recommend following an established vaccine schedule. Vaccines protect against life-threatening infections, including those that disproportionately affect infants and young children.

Good Hygiene

While no vaccine can prevent one from common cold, good hygiene practices can significantly reduce germ transmission. Parents must therefore encourage their children to wash their hands after touching toys, hard surfaces, and other people. What is more important is proper hand hygiene, as handwashing with soap and water is the most effective way to eliminate germs.

The Hygiene Hypothesis: Does Exposure to Germs Strengthen Immunity?

There are several research that suggests that early exposure to germs may help develop a child’s immune system, a concept known as the "hygiene hypothesis." However, many immunologists argue against this theory, noting that children naturally encounter enough germs to build immunity without unnecessary exposure to unsanitary conditions. A balanced approach ensures children develop a strong immune response without increased risk of illness.

Cleaning and Sanitizing Children’s Belongings

Regular cleaning of toys, school supplies, and frequently touched objects is essential. Understanding the difference between cleaning, sanitizing, and disinfecting can help:

• Cleaning removes visible dirt and debris.
• Sanitizing reduces germs to safer levels.
• Disinfecting kills germs completely, offering the highest level of protection.

It is important to read product labels carefully, use child-safe cleaning products, and rinse toys thoroughly after disinfection, especially those that go into a child’s mouth.

Choosing Effective Sanitizing Products

To minimize germ exposure, parents should clean objects with soap and water first and then use a sanitizer for everyday items. Disinfectants, which are stronger, should be used on objects that a sick person has touched. The Environmental Protection Agency (EPA) provides a list of approved sanitizers and disinfectants that effectively kill germs.

Encouraging Good Hygiene Without Causing Anxiety

Teaching children proper hygiene without creating fear is essential. Make handwashing engaging by incorporating songs or counting games. Explaining the benefits of hygiene in a positive way helps children understand that washing hands protects them and others. Parents can reinforce these habits by leading by example.

Boosting Immunity Through Nutrition

A strong immune system helps children fight infections more effectively. Proper nutrition plays a crucial role in immune support. A balanced diet should include:

• Proteins
• Vegetables
• Fruits
• Healthy fats
• Carbohydrates
• Adequate hydration

Multivitamins are generally unnecessary for well-nourished children, but if supplements are used, they should be free of added sugars and taken under supervision to prevent choking hazards.

Teaching Respiratory Etiquette

Proper respiratory hygiene reduces the spread of illness. Parents should model behaviors such as covering their mouths with an elbow when coughing or sneezing. Using tissues and disposing of them immediately is also a good practice. Reinforcing these habits through positive encouragement makes children more likely to adopt them.

Parents may notice that a child’s feet point inward while walking or running. This is called in-toeing. It is common in young children and, in most cases, reflects normal development of the foot or leg bones. Many children improve naturally as they grow, without treatment.

However, it is not always helpful to dismiss a persistent or troublesome walking pattern as “just a growing phase.” The child’s age, the cause, whether the pattern is worsening, and its effect on movement all matter.

What can cause in-toeing?

In-toeing usually comes from one or more of three areas:

1)Foot: The front of the foot curves inward, a condition called metatarsus adductus. Flexible cases often improve naturally.

2)Shin: The shin bone turns inward, called internal tibial torsion. This is common in toddlers and usually improves with growth.

3)Thigh: The thigh bone turns inward, called femoral anteversion. It may become more noticeable when a child begins running or walking with the feet turned in.

The appearance of the feet alone does not always reveal the cause. A clinician can assess the child’s walking pattern and examine the hips, knees, shins and feet.

When should parents seek advice?

An occasional inward-pointing step, without pain or difficulty, usually needs observation rather than treatment. Arrange an assessment if the child:

• Trips or falls often, or has difficulty running, jumping or keeping up with peers.
• Avoids play or sports because of the way they walk.
• Has pain, swelling, a limp or difficulty bearing weight.
• Has a marked difference between the two legs.
• Develops a new or rapidly worsening walking pattern.
• Has a foot that is rigid or cannot be gently moved toward a straight position.
• Pain, limping, sudden onset, or marked asymmetry are reasons to look beyond a routine developmental variation.

What does assessment involve?

The clinician will ask when the in-toeing began, whether it is changing, and whether it affects daily activities. They will observe the child standing and walking, and assess foot flexibility, hip and leg rotation, balance and function.

X-rays are not routinely needed when the history and examination fit a typical developmental pattern. They may be considered if there is pain, trauma, unusual examination findings or concern for another condition.

Does every child need physiotherapy, special shoes or braces?

No. For typical, painless developmental in-toeing, reassurance and observation are usually appropriate. Special shoes, braces and orthotics do not correct the usual rotational causes. Physiotherapy may help when there is a separate issue—such as weakness, balance difficulty or impaired coordination—but it does not generally change the underlying bone rotation.

If in-toeing is severe, persistent and causing substantial functional difficulty, a paediatric orthopaedic specialist can advise whether further evaluation or treatment is appropriate. Surgery is rarely needed and is generally considered only for older children with severe deformity and significant functional problems.

A practical message for parents: Most children with in-toeing walk and play normally, and their alignment improves as they grow. The aim is not to make every child’s walking look identical; it is to ensure the child moves comfortably and safely. Seek an assessment for pain, limping, sudden change, pronounced asymmetry or meaningful difficulty with everyday activities.

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.

What Is Premenstrual Dysphoric Disorder (PMDD)?

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.

By Dr Sushma K, Obstetrics, Gynecology and Reproductive Medicine, Apollo Hospitals, Seshadripuram, Bangalore told HealthandMe, "It is a chronic medical condition related to the menstrual cycle. It affects approximately around 3 to 8 percent of the women who are menstruating. So it not only causes physical symptoms, like premenstrual syndrome, it also causes emotional and psychological symptoms. It typically occurs one or two weeks before menstruation starts."

Unlike premenstrual syndrome, PMDD can significantly interfere with a person's ability to work, relationships, social life and other daily activities. When it comes to symptoms, patients can have sudden onset of sadness, increased sensitivity, or tearfulness, sudden spells of crying, severe irritability, anger, depressed mood and anxiety.

Dr Sushma said, "These emotional symptoms can also have physical manifestations. For example, decreased interest in going to school, office, and difficulty concentrating. Some may resort to overeating. Some may have excessive sleepiness or some may face insomnia. Some also experience restlessness, discomfort, joint swelling, muscle pain, and abdominal bloating.”

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.

Dr Sushma said, "PMS is a mild to moderate condition and it can be easily managed. It comes with physical symptoms like bloating, breast pain, tiredness, and mood changes. It also does not interfere with people’s daily routine and relationships. It occurs in almost around 75% of the people who are menstruating."

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

She added, "But PMDD is more severe. It will impair daily life. It also causes more intense psychological and emotional symptoms than physical symptoms."

So 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.

Dr Sushma explained, "PMDD is a very severe depressive disorder. Patients may have panic attacks, depression, and thoughts of self-harming. So these are the key main important differences. PMDD may happen because of disrupted dysfunctions in the central nervous system during the menstrual cycle. That is because of how the central nervous system reacts to the normal estrogen and progesterone levels during the menstrual cycle.”

PMDD In New Mothers

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.

Dr Sushma said, "New mothers may not face premenstrual dysphoric disorder because there is no ovulation. The lady is not menstruating because she is lactating. But once the ovulation starts, the symptoms of PMDD will return. These symptoms can worsen because the mother is sleep deprived or she faces a lot of hormonal changes. There is also a newborn. So the baby’s care-giving also adds to the stress. So PMDD may get aggravated in new mothers."

PMDD should also not be confused with postpartum depression. Postpartum depression can occur after childbirth and is not restricted to the days before menstruation.

The doctor explained, "Postpartum depression is not cyclical. Whereas PMDD will come in a cyclical manner, mostly 10-12 days before periods, which is usually in the luteal phase. Also, it may resolve after the bleeding starts.

Whereas postpartum depression is not related to the menstrual cycle."

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.
