How Safe Is It To Use Microwave For Reheating Food?

Updated Feb 9, 2025 | 09:00 AM IST

SummaryAccording to research, when certain plastics are subjected to heat, they produce compounds such as phthalates and bisphenol A (BPA). These substances have been associated to hormonal disturbance, metabolic problems, and perhaps reproductive concerns.
Microwaving food

Microwaves are a common appliance in every household now. You will see it in kitchens of not just houses, but offices, cafeterias, and co working space. However, there are studies that show that heating food in a microwave could be a health concern. While it does come handy, there are questions about harmful radiation and nutrient loss and heating safety that still linger.

Does Microwave Destroy The Nutrients In Food While Heating?

Some research suggests that microwaving may cause nutritional loss, particularly in vegetables. For example, studies have shown that microwaving broccoli with water diminishes its flavonoid content, which are anti-inflammatory compounds. However, experts note that cooking method and duration have a significant influence on nutrient retention.

Surprisingly, several studies indicate that microwaving preserves more nutrients than traditional cooking methods. A study comparing microwaved versus oven-cooked ready meals found that the microwaved version contained somewhat more vitamin C. Another study discovered that microwaving some vegetables, such as broccoli and green beans, may retain more beneficial compounds than boiling.

Ultimately, the nutrient loss really vary on the type of food which is being heated and how it is being cooked. Experts also recommend using minimal water and shorter cooking times to maximize the nutrient retention.

Is Heating In Plastic Safe?

Plastic containers and heating food in it, has always been a topic of debate. While containers do come with microwave-safe stamps, is it really safe to heat them with food?

According to research, when certain plastics are subjected to heat, they produce compounds such as phthalates and bisphenol A (BPA). These substances have been associated to hormonal disturbance, metabolic problems, and perhaps reproductive concerns.

A study also took in account over 400 plastic food containers that were microwave-safe and found that most of them leaked hormone-disrupting chemicals. These are phthalates, warn experts, which are commonly used in food packaging and can interfere with body's hormonal balance, and increase risk of diabetes or even high blood pressure.

Additionally, BPA exposure has been associated with fertility issues and immune system disruptions.

So, what can be done instead?

To minimize this risk, experts recommend using glass or ceramic container when microwaving foods. If you must use a plastic container, make sure the container is not damaged or old, as they are more prone to leach harmful chemicals.

What About The Radiation?

Concerns about microwave radiation have been largely debunked by decades of research. Microwaves use non-ionizing radiation, which does not have enough energy to damage DNA or cause cancer. The electromagnetic waves used in microwaves are similar to those from radios and light bulbs.

Experts emphasize that microwave ovens are designed to contain radiation, preventing exposure. As long as the microwave is in good condition and the door seals properly, there is no significant health risk from microwave radiation.

Other Concerns

Microwaving food could sometimes also lead to uneven cooking and it can create some risks to food safety. Thus, experts advertise to use microwave only to reheat the food and not to actually cook raw food. For safe reheating, food should reach at least 82°C (176°F) throughout to kill bacteria.

The life of a woman can be called a cycle of various physical and hormonal changes occurring at particular points throughout life. From menstruation at puberty up to menopause, there will be numerous changes experienced by the female body, which can bring about consequences for her physical and psychological well-being.

Being a healthcare professional, I should mention that although medication is sometimes unavoidable, there is no point in neglecting alternative ways, including yoga.

Yoga Can Help Women

Yoga is an exercise that involves asanas, pranayamas, and meditation. There is now scientific evidence indicating that yoga aids in coping with certain conditions in women. It achieves this by positively influencing the neuroendocrine, autonomic nervous system, and stress responses.

A significant number of women are victims of menstrual conditions such as dysmenorrhea, PMS, abnormal menstrual cycle, and heavy menses during their reproductive age. The conditions may become worse due to stress, since it affects hormone levels.

Yoga reduces the amount of congestion in the pelvic area, increases blood flow, increases body flexibility, and reduces stress hormones such as cortisol. Consequently, most women have painless and psychologically stable menstruation.

Yoga Can Improve PCOS Symptoms

Moreover, yoga can prove highly helpful in the case of women who are suffering from Polycystic Ovary Syndrome (PCOS). It is the most prevalent endocrine disorder that affects women of childbearing age.

The condition has insulin resistance, obesity, irregular menstruation, and metabolic conditions as its symptoms. Thus, yoga, along with healthy living, can provide some assistance in terms of improving insulin levels, maintaining weight, reducing stress, and balancing hormones.

Yoga in Pregnancy

Yoga has many advantages during pregnancy. It will ensure good posture, decrease lower back pain, increase flexibility, improve breath control, and prepare the body for delivery. In addition, prenatal yoga helps with dealing with emotional and mental issues related to pregnancy, which will have a positive effect on the mother and her baby.

Yoga During Perimenopause And Menopause

With the onset of perimenopause and menopause, the reduction in levels of estrogen is known to cause side effects like hot flashes, insomnia, irritability, exhaustion, aches in the joints, and thinning bones. All these factors have significant impacts on both the daily life activities and the emotional state of women.

The research shows that yoga may be helpful in overcoming the symptoms of menopause through relaxation, improvement in sleep, muscle strengthening, and better handling of emotions. Breathing techniques and meditation help in lowering stress and positively influencing the mental state of patients.

Apart from the specific diseases that yoga can alleviate, it promotes self-awareness, which plays an important role in managing one’s emotions. Nowadays, women tend to have a large number of duties, such as working, taking care of children, and doing housework. Chronic stress leads to many diseases, for instance, high blood pressure, obesity, heart issues, and psychological problems.

For all phases of female development, from menstruation until menopause, the emphasis should be on not just the treatment of diseases but the maintenance of wellness. While yoga cannot replace medical care, it remains an important supplement that aids in achieving physical fitness as well as mental and spiritual well-being. Through regular yoga practice, a woman will develop her resilience and become stronger in every phase of life.

Yoga can act as a "polypill" by addressing multiple underlying factors that contribute to lifestyle diseases, according to Dr. Rima Dada, Professor at the All India Institute of Medical Sciences (AIIMS), who has been studying yoga and its impact on lifestyle disorders for the past 20 years.

Speaking about her research, Dr. Rima said yoga is a profound science, technology, and art of living that can tackle factors that set the stage for a wide range of diseases.

Yoga May Benefit Multiple Health Conditions

According to Dr. Rima, yoga can help address conditions including hypertension,

  • coronary artery disease,
  • polycystic ovarian syndrome (PCOS),
  • unexplained male factor infertility,
  • primary open-angle glaucoma,
  • autoimmune diseases,
  • rheumatoid arthritis,
  • Alzheimer's disease.
She noted that these conditions share several common underlying factors, including

  • accelerated ageing,
  • shorter telomeres,
  • persistent activation of the hypothalamic-pituitary-adrenal axis,
  • a dysregulated immune system,
  • high levels of stress and anxiety,
  • inflammation,
  • oxidative stress.

Yoga's For Oxidative Stress And Inflammation

Dr. Rima said evidence-based studies conducted by her team have shown that yoga addresses these underlying factors.

According to the findings, yoga reduces oxidative stress by increasing the expression of various antioxidants. It also improves mitochondrial health and reduces free radicals produced as by-products of ATP production.

The studies further showed that inflammation decreases because the expression of genes coding for anti-inflammatory factors increases, while the expression of genes that promote inflammation declines.

Yoga May Support Brain Health

The research also found that yoga increases the expression of genes involved in DNA repair. In addition, yoga promotes parasympathetic dominance, resulting in increased rest, repair, and digestion.

Dr. Rima said yoga also positively modulates the epigenome and increases the expression of factors beneficial for overall health. She noted that yoga promotes brain health, improves mental well-being, and enhances the production of factors associated with neurogenesis in key areas of the brain. These changes may help improve memory and build emotional resilience.

Gut-Brain Axis and Immune Health

Dr. Rima said yoga has also been shown to improve gut microbial flora, helping maintain the integrity of the gut-brain axis.

According to her, this supports the secretion of factors that help maintain immune, endocrine, and mental health.

Yoga Is An Entire Lifestyle

Emphasizing that yoga extends beyond physical postures, Dr. Rima said it is an entire lifestyle that includes diet, asanas, pranayama and dhyana.

She said yoga and asanas help bring the body into proper geometry and alignment, while also improving flexibility, range of motion and neuromuscular coordination.

This alignment, she explained, enables more effective breathing. Nasal inhalation and exhalation activate certain areas of the brain that promote a state of relaxed wakefulness.

Yoga Is The Need of The Day

Dr. Rima said effective breathing increases blood flow to the brain and raises nitric oxide levels, which help improve circulation while reducing inflammation and oxidative stress.

"Thus, yoga is a polypill and is the need of the day," she said.

Heavy menstrual bleeding caused by fibroids and other gynecological conditions is a major but often overlooked contributor to anemia among Indian women, said Dr. Roma Sinha, Chief Gynecologist and Director of Gynecological Robotic Surgery at Apollo Hospitals, Hyderabad, today.

Speaking at the Times Network India Health Summit 2026 at Hyderabad, Dr. Sinha highlighted how many women normalize excessive menstrual bleeding and delay seeking medical attention, often leading to severe anemia and a reduced quality of life.

Fibroids And Heavy Bleeding Behind Anemia

According to Dr. Sinha, it is not uncommon for women to visit her clinic with hemoglobin levels as low as five or six grams per deciliter.

"Most of the time, it is not nutritional anemia. Women lose so much blood during their menstrual cycles that they are unable to rebuild their hemoglobin levels," she said.

While national programs such as Anemia Mukt Bharat focus heavily on pregnant women, Dr. Sinha pointed out that anemia occurring during other stages of a woman's life often goes unnoticed.

She said many women learn from family members and friends that heavy bleeding is "normal" and simply continue to suffer without seeking treatment.

Fatigue And Poor Quality Of Life

Beyond the underlying disease, Dr. Sinha emphasized the impact heavy menstrual bleeding has on women's daily lives.

"Many women think they are tired because of stress, work, or family responsibilities. But often it is low hemoglobin and iron deficiency causing that fatigue," she said.

The expert noted that a simple hemoglobin test can help diagnose anemia, yet many women continue to prioritize the health of their families over their own well-being.

Lack of Awareness

Dr. Sinha identified lack of awareness and negligence as two major reasons why women delay medical consultations.

"Heavy bleeding occurs only for a few days every month, so women tend to tolerate it and move on. Many don't realize that it is treatable and that ignoring it can lead to dangerously low hemoglobin levels," she said.

The expert stressed the need for greater public awareness and open conversations about menstrual health.

"It should not be a taboo to talk about heavy menstrual bleeding," she added.

Surgery Not The Only Treatment Option

A common fear among women, Dr. Sinha said, is surgery. Many patients avoid consultations because they assume treatment will automatically mean a hysterectomy —the surgical removal of the uterus— after which pregnancy is impossible, the top gynecologist said. However, she clarified that surgery is not the only option available for fibroids.

"Fibroids are largely benign tumors. Women today have choices, including medical management, non-invasive treatments, myomectomy, or hysterectomy, depending on their individual needs and preferences," she said.

The expert added that modern technologies such as robotic surgery have significantly improved outcomes for women requiring treatment.

Dr. Sinha also highlighted long-term research conducted on women who underwent robotic surgery for fibroids.

"We followed patients for ten years and found that 86.3 per cent conceived and delivered successfully after surgery," she said.

The findings, she noted, should reassure younger women concerned about fertility after fibroid treatment.

While early detection cannot eliminate fibroids completely, Dr. Sinha said it can prevent severe anemia and improve overall quality of life. "Current treatments can control symptoms and act as bridge therapies, helping women avoid complications and delay more definitive treatment when appropriate," she explained.

'Don't Ignore Heavy Bleeding'

In her message to women, Dr. Sinha urged them to listen to their bodies and seek help when they notice abnormal menstrual bleeding.

"If you feel your periods are heavier than normal, don't ignore it. Get a simple hemoglobin test and consult a gynecologist," she said.

Dr. Sinha also called on families, particularly men, to support women in seeking care and to pay attention when they complain of persistent fatigue or excessive menstrual bleeding.
