Do you find yourself struggling to fall asleep or stay asleep throughout the night? You’re not alone. Insomnia is a prevalent sleep disorder that impacts millions of individuals worldwide, disrupting their ability to get sufficient rest. While sleep requirements differ from person to person, most adults need at least seven hours of quality sleep each night. If you’re frequently tossing and turning, certain natural remedies and lifestyle changes may help restore a restful night’s sleep.

Mindfulness Meditation for Deep Relaxation

Practicing mindfulness meditation, which involves slow and steady breathing while observing thoughts and sensations without judgment, can significantly enhance relaxation. This method is known to reduce stress, improve focus, and promote a sense of calm, all of which contribute to better sleep. A study conducted in 2011 revealed that individuals who practiced mindfulness meditation experienced notable improvements in their sleep patterns. Taking 15 minutes each morning or evening to meditate, or following a guided session online, can help create a soothing pre-sleep routine.

Mantra Repetition for Mental Calmness

Repeating a mantra or a positive affirmation before bed can help quiet the mind and induce relaxation. A 2015 study found that homeless women who engaged in mantra repetition experienced reduced symptoms of insomnia. Select a calming phrase, such as “I am at peace” or "Sleep comes naturally to me" and repeat it mentally or aloud before bedtime to help ease your mind and transition into sleep more smoothly.

Yoga to Relieve Stress

Yoga has been linked to enhanced sleep quality, reduced stress, and improved mental clarity. Styles like yin yoga and restorative yoga focus on slow movements and controlled breathing, making them ideal for relaxation. Incorporating yoga into your weekly routine, or practicing a short session before bedtime, can prepare both your body and mind for restful sleep.

Exercise for Healthier Sleep Patterns

Engaging in regular physical activity not only benefits overall health but also enhances sleep quality. A 2015 study found that individuals who exercised for at least 150 minutes per week reported fewer symptoms of insomnia, along with decreased anxiety and depression levels. Aim for at least 20 minutes of moderate exercise daily, but try to complete workouts earlier in the day to avoid overstimulation before bedtime.

Massage Therapy for Relaxation

Massage therapy has been found to improve sleep quality by reducing stress, pain, and anxiety. While professional massages can be beneficial, self-massage or help from a partner can also promote relaxation. Focus on gentle techniques to calm the body and mind before heading to bed.

Magnesium for Muscle Relaxation

Magnesium is an essential mineral that helps relax muscles and alleviate stress, thereby promoting restful sleep. A 2012 study found that individuals who took 500 mg of magnesium daily for two months experienced significant improvements in sleep quality. Magnesium can be taken as a supplement or absorbed through a warm bath infused with magnesium flakes.

Lavender Oil for a Calming Effect

Lavender is widely recognized for its ability to improve mood and encourage relaxation. Studies suggest that lavender oil capsules can enhance sleep quality, particularly in individuals suffering from anxiety or depression. Diffusing lavender oil in the bedroom or adding a few drops to your pillow can create a tranquil atmosphere conducive to restful sleep.

Melatonin for Sleep Regulation

Melatonin, a hormone that regulates the sleep-wake cycle, has been shown to aid in falling asleep faster and improving overall sleep quality. A 2016 study found that melatonin supplementation significantly benefits individuals experiencing insomnia. Taking 1 to 5 mg of melatonin 30 minutes to two hours before bedtime can facilitate an easier transition into sleep.

When To Consult A Doctor

If natural remedies and lifestyle changes fail to improve sleep quality, seeking medical advice may be necessary. Chronic insomnia could be linked to underlying health conditions such as diabetes, thyroid disorders, cardiovascular issues, or respiratory diseases. In such cases, behavioral therapy or medical intervention may be required to address persistent sleep disturbances.

Even a mild case of COVID-19 may trigger long-lasting eye problems, with new research revealing that persistent inflammation and nerve damage could be responsible for symptoms that standard eye tests often fail to detect.

The study, led by researchers at Linköping University in Sweden and published in Nature Communications, sheds light on why some COVID-19 survivors continue to experience debilitating vision issues months or even years after infection.

The research began after people who had recovered from mild COVID-19 sought medical help for persistent eye complaints. Many reported:

• Severe eye pain
• Light sensitivity (photophobia)
• Difficulty reading and focusing
• Extreme eye fatigue

Many participants said the condition significantly disrupted their daily lives, preventing them from working or continuing their education.

What the Study Found

Researchers evaluated 100 people who developed eye problems after mild COVID-19 but had never been hospitalized. Their symptoms had persisted anywhere from three months to three years.

The findings were compared with those of 32 people who had recovered from mild COVID-19 without developing eye symptoms.

Using advanced imaging and laboratory techniques, researchers identified several abnormalities that conventional eye exams failed to detect.

Persistent Inflammation and Nerve Damage

The study found evidence of:

• Long-term inflammation in the eyes
• Damage to nerves controlling multiple eye functions
• Abnormal immune activity involving T cells
• Changes in proteins found in tear fluid

Lead author Petros Moustardas, senior research associate at Linköping University, said the findings indicate that COVID-19 may trigger a severe immune reaction in the eyes, resulting in chronic inflammation and nerve dysfunction.

One of the most common complaints among participants was extreme sensitivity to light. Researchers found that their pupils were allowing too much light into the eyes because of impaired nerve control.

This abnormal pupil function was also associated with:

• Headaches
• Difficulty reading
• Trouble maintaining focus

An Unusual Eye Movement Disorder

The study also identified impaired coordination between the two eyes.

Some participants developed adult-onset strabismus—commonly known as crossed eyes—a condition that is rare in adults.

Researchers believe this occurred because COVID-19 affected the nerves responsible for controlling eye muscles.

A New Way to Diagnose COVID-Related Eye Problems

Because routine eye tests often miss these abnormalities, the research team developed two diagnostic models.

The first relies on specialized ophthalmic tests available at advanced eye clinics, while the second combines these examinations with tear fluid protein analysis to improve diagnostic accuracy.

Researchers hope these models will help doctors recognize COVID-related eye syndrome earlier and pave the way for future treatments.

"We found that the problems experienced by those affected were not detectable by standard tests. We had to perform specialised examinations to detect deviations. The puzzle pieces then fell into place, and we found explanations for the symptoms," said Neil Lagali, professor of experimental ophthalmology at Linköping University.

He added that while the findings provide important clues about how COVID-19 affects the eyes, more research is needed to develop effective treatments for those living with persistent vision problems.

Plant-based Vitamin D3 is often marketed as a healthier or superior alternative to traditional supplements, but doctors say that's not necessarily the case.

According to Dr. Murtaza S. Bagwala, Head of Emergency Medical Services at Saifee Hospital in Mumbai, existing research shows that plant-based Vitamin D3 is just as effective as conventional Vitamin D3 in increasing the body's vitamin D levels.

"Current evidence suggests that plant-based Vitamin D3 performs similarly to conventional Vitamin D3 supplements. For people who prefer vegan or plant-based products, it is a suitable alternative," he told HealthandMe.

Echoing this view, Dr. Sudhir Kumar, Neurologist at Apollo Hospitals in Hyderabad, said that plant-derived Vitamin D3—usually obtained from lichen, algae, or modern fermentation methods—provides an animal-free option without sacrificing effectiveness.

In a post on X, he noted that while plant-based Vitamin D3 is welcome news for vegans and those seeking cruelty-free supplements, both forms work equally well. He added that there is no medical need for people to switch if they are already taking conventional Vitamin D3 supplements.

India has approved its first plant-based Vitamin D3 (cholecalciferol) ingredient, a move that could expand options for food fortification and dietary supplements while addressing the country's widespread Vitamin D deficiency.

The Food Safety and Standards Authority of India (FSSAI) has cleared VITADEE Green, developed by Fermenta Biotech, for use in health supplements, nutraceuticals and food products.

The company stated that the ingredient is produced using an India-patented process and offers a sustainable, scalable and vegetarian-friendly source of Vitamin D3.

The approval allows Indian manufacturers to incorporate the ingredient into fortified foods, beverages and dietary supplements.

It is particularly significant for vegetarians and vegans, who have traditionally had limited access to Vitamin D3 because most supplements are derived from lanolin, a by-product of sheep's wool.

The approval also supports India's broader efforts to improve nutrition through food fortification, an area where experts say Vitamin D remains a major gap.

What Is Vitamin D3?

Vitamin D3, often called the "sunshine vitamin," is produced by the body when the skin is exposed to sunlight.

It helps the body absorb calcium, maintain healthy bones and teeth, and lowers the risk of fractures. In children, severe deficiency can lead to rickets, while in adults it increases the risk of osteoporosis, muscle weakness, and falls.

Beyond bone health, Vitamin D3 also supports immune function. Research suggests low Vitamin D levels may be associated with increased susceptibility to infections and higher levels of inflammation.

Who Should Take Vitamin D3 Supplements?

The experts said the key question is whether supplementation is needed, not whether the source is plant- or animal-derived.

"The source matters mainly for ethical, dietary or personal preference—not for efficacy," Dr. Sudhir said.

Dr. Bagwala cautioned against taking high-dose Vitamin D without medical advice, as excessive intake can raise calcium levels and increase the risk of kidney stones and other complications.

Yawning has a certain fact attached to it, which is without a doubt a reason for curiosity and amazement among people. Many of you must have noticed that when someone nearby yawns, you often end up yawning too. Even in some cases, a person yawns just after hearing the word yawn or watching someone yawn on screen.

Yawning itself is a natural physical process that involves taking a deep breath and stretching the muscles used for breathing. Some experts suggest that it may help increase alertness and leave us feeling refreshed. However, while scientists have proposed several theories about the purpose of yawning, one question continues to intrigue researchers: why are yawns so contagious?

Dr. Debanjan Pan, Consultant Psychiatrist at Saltlake Mindset, told Health and Me, "Contagious yawning may be linked to mirror neurons, which help us understand and imitate the behavior of others. Humans have survived by living in groups, and our brains are naturally wired to synchronize with the people around us. When we see someone yawn, the same neural networks in our brains may become activated, prompting us to yawn as well."

Yawning involves taking a very deep breath, which increases oxygen intake and stimulates several parts of the respiratory system. This deep inhalation can temporarily raise the heart rate and boost blood circulation to the spinal cord and the brain, making a person feel calmer and more relaxed afterward.

According to Dr. Pan, this sense of relaxation may also explain why yawning is contagious. When we see someone else yawn, the brain's empathy circuits, particularly those linked to mirror neurons, become active. As humans are highly social beings, we often unconsciously mimic the behaviour and emotions of people around us, causing a yawn to spread from one person to another.

But there might be a question: if yawning is contagious because humans are social animals and human brains are naturally wired to synchronize with the people around them, then why doesn't coughing and sneezing have the same effect?

Dr. Vikas Mittal, Director - Pulmonologist, CK Birla Hospital, Delhi, addressed this very issue and explained, "Yawning is different than coughing and sneezing. Coughing and sneezing are protective reflexes that protect you from irritants. They can be contagious, but that contagion comes after one or two days, not immediately as is with yawning. Yawning occurs because of the brain's automatic self-mirroring networks."

Dr. Mittal further added, "What it means is when somebody yawns, then your brain starts imitating that unintentionally. Not only yawning, but other emotions like a smile, laugh, and fear can trigger the same emotion in the people around you. This is because of the same brain's automatic self-mirroring networks."

Contagious yawning appears to be more than a simple reflex, offering insights into empathy, social bonding, and the human brain.
