Doctors reveal 9 signs of low vitamin D that may cause fatigue during monsoon
Vitamin D plays a vital role in various bodily functions, including bone health, muscle strength, immune response, and emotional well-being. Unlike most other vitamins, which we primarily obtain from food, vitamin D is produced by our bodies when our skin is exposed to sunlight, particularly UVB rays. During the rainy season, when outdoor activities decrease and the skies are often cloudy, our exposure to sunlight drops significantly, leading to a sharp decline in vitamin D levels for many people, as reported in The Journal of Nutrition.
9 signs of vitamin D deficiency
Low vitamin D levels do not always manifest as clear-cut symptoms. Instead, they can present in vague ways, making it easy to overlook them. Dr Siri M Kamath, Consultant Internal Medicine, Gleneagles BGS Hospital, Kengeri, Bengaluru, tells Health Shots ten signs of low vitamin D that may be contribute to fatigue during the monsoon season:
1. Persistent fatigue
Feeling tired throughout the day, despite getting adequate rest, is a common symptom of low vitamin D levels. This persistent fatigue can significantly impact your daily activities, making even simple tasks seem more challenging.
2. Unexplained muscle ache
Do you find yourself experiencing muscle soreness that you can't quite explain? Low vitamin D may be the reason. A deficiency can lead to muscle weakness and vague aches, causing discomfort during regular activities.
3. General body heaviness
An overall feeling of heaviness in the body—sometimes described as a lack of energy to move—can also stem from insufficient vitamin D levels. This feeling might be dismissed as seasonal lethargy, but it warrants attention.
4. Changes in mood
If you've noticed increased irritability or feelings of sadness, low vitamin D levels could be a contributing factor. Several studies published in Springer Nature suggest a link between vitamin D deficiency and mood disturbances, including depression and anxiety. Extreme fluctuations in mood without apparent cause can indicate a deficiency. If you find yourself feeling unusually down or irritable, consider the possibility that you may have low vitamin D levels.
5. Difficulty concentrating
Having trouble focusing or experiencing mental fog can be linked to low vitamin D levels. This can significantly impact productivity and overall mental clarity.
6. Weakened immune response
Frequent colds or infections can indicate a weakened immune system, which may be linked to low vitamin D levels. This vitamin plays a vital role in immune function, and deficiency can increase susceptibility to illnesses.
7. Bone pain or weakness
Vitamin D is vital for calcium absorption; a deficiency might lead to weakened bones and an increased risk of fractures. If you notice chronic bone pain, it could be time to assess your vitamin D levels.
8. Sleep disturbances
Difficulty falling asleep or staying asleep may also be a sign of low vitamin D levels. Restorative sleep is vital for overall health, and this vitamin plays a vital role in regulating sleep patterns.
9. Increased sensitivity to pain
Low vitamin D can heighten pain sensitivity. If you notice that you are more sensitive to pain during the rainy months, evaluate your vitamin D levels, as this could make a significant difference in your comfort.
Who is at risk of low vitamin D?
Certain groups of people are more prone to vitamin D deficiency. "Individuals who spend most of their time indoors, whether due to work constraints, age, or lifestyle choices, are particularly at risk. Individuals with darker skin also require more sunlight to produce adequate levels of vitamin D, thereby increasing their risk of deficiency," diabetologist Dr Siri M Kamath tells Health Shots. Moreover, as we age, our skin loses its ability to synthesise vitamin D efficiently, making older adults more susceptible to vitamin D deficiency, as per research published in Springer Nature.
How to diagnose vitamin D deficiency?
Are you experiencing several of the signs mentioned above? In that case, it is advisable to consult your healthcare provider about your vitamin D levels. The simplest method of diagnosis is a routine blood test. If your levels are found to be below normal, your doctor can recommend appropriate supplements.
"The dosage of vitamin D can vary based on how low your levels are. In some cases, you may need weekly or monthly supplements to restore balance. It is essential to consult a doctor for medical supervision, as both deficiency and excess can have adverse health consequences. While dietary sources like fortified milk, eggs, and fatty fish can help improve your vitamin D levels, they usually aren't enough to correct a significant deficiency," says Dr Siri M Kamath.
Best time for vitamin D exposure
As the clouds clear and the rainy season comes to an end, it's a perfect opportunity to increase your sun exposure gradually. Aim for just 15 to 20 minutes of direct sunlight on your arms and face a few times a week, preferably before 11 a.m. This minor adjustment can be a significant step towards maintaining adequate vitamin D levels.
However, for those with a diagnosed deficiency, sunlight alone may not suffice. Often, a simple correction can lead to a noticeable improvement in your energy levels and overall well-being. Not only can this enhance your day-to-day quality of life, but addressing low vitamin D can also protect your long-term bone health and immune function.

‘I struggled with breastfeeding after gestational diabetes': Expert explains if blood sugar levels affect milk supply
Breastfeeding, I was told, is one of the most intimate and powerful experiences after childbirth. That quiet we-time, skin-to-skin bond was meant to be sacrosanct to not just nurture my baby, but also help me establish connect as a new mother. What nobody prepared me for was the physical and emotional struggle that breastfeeding could be. Gestational diabetes can impact breastfeeding, but it can be managed with the right diet and physical and emotional support.(Adobe Stock) I am Radhika Bhirani, Editor at Health Shots, a women's health and wellness platform by Hindustan Times - and this is my story. My baby refused to latch. He cried - almost howled - the moment I would try to brush his lips against the breast. I cried for hours, helpless that I wasn't being able to do even the most basic thing a mother is expected to do. A lactation expert dismissed me, "He was latching in the hospital". The paediatrician said, "You seem to have given up already... You're not trying hard enough, mommy". The pressure kept building. I tried fenugreek tablets and other galactagogues, but nothing helped. I thought 'Let's use the breast pump, shall we?' But hours of breast pumping could not produce even 5 ml of breast milk a day. It struck me that perhaps gestational diabetes affected my milk production, considering I was on insulin and pills to manage my high blood sugar levels during pregnancy. Sane and supportive voices around me reminded me that 'Breast may be best, but fed is truly best'. And so, we settled for feeding the little one with formula milk instead of keeping him hungry and crying. However, the question about how gestational diabetes impacts breastfeeding, was worth getting an answer for. For World Breastfeeding Week 2025, I took a leaf out of my personal journey, and asked Dr Esha Gupta, Consultant - Paediatrics, Paediatric Intensivist and Lactation expert, Motherhood Hospitals, Bengaluru, about it. "For most first-time mothers, breastfeeding also comes with its own set of expectations and complications. One of the most common things to worry about for a woman who has developed diabetes during pregnancy is, 'Will this affect my ability to make milk?' But the short answer is — it possibly will, but it isn't definitive, and there are a lot of things that can be done to ensure healthy milk output," Dr Gupta tells Health Shots. What is gestational diabetes? Diabetes that typically shows up in the second or third trimester of pregnancy is gestational diabetes mellitus (GDM). It alters the method in which your body metabolizes insulin and creates higher blood sugars that will impact both baby's and mom's health, if not managed. It usually goes away after delivery — but its impact can persist, especially while nursing, the expert explains. Can gestational diabetes affect milk supply? Milk production is delayed in some mothers due to high blood sugar levels during pregnancy. "Additional evidence shows that gestational diabetes mellitus retards the onset of milk production (lactogenesis II), which must be established 2–4 days postpartum," says Dr Gupta. This happens because of insulin, which plays an important part in the hormonal ecosystem for milk production. "For insulin-resistant women — the typical gestational diabetes profile — the body is perhaps not picking up so quickly on the lactation signals. Mix in other risk factors like obesity, PCOS, or hard labor, and the milk 'coming in' will be delayed. What is important to note is that delay is not failure. It is seen that breastfeeding is not an issue when it comes to well-supported and well-fed mothers. Mothers, if provided with a good diet along with ample mental support, helps them to continue with breastfeeding," she adds. Breastfeeding can be hard if a baby doesn't latch or enough milk is not produced. (Freepik) For all women, gestational diabetes doesn't mean you'll not be able to breastfeed. But some may take a little longer and a little more help. What to expect? You can anticipate the first 1–2 days of colostrum (thick yellow milk) production to be in small quantities. Your breasts will be fuller once mature milk comes on day 3 or 4. In case your baby is not wetting diapers (key sign of well-fed baby) or your breasts don't feel full, it is worth a visit to a lactation consultant. Tips to stimulate healthy milk production 1. Early and frequent breastfeeding: Try to breastfeed the infant in the first hour. Breastfeed 2–3 times with a 2–3 hour interval even if it feels like nothing is happening. Stimulation is critical as early as possible. 2. Hand expression or pumping: If the baby is sleeping or having trouble latching (more frequent in diabetic mothers' babies), start pumping at 6 hours postpartum. Pump 8–10 times within 24 hours. 3. Skin-to-skin first priority: This activity is not just about snuggling your baby. It is also said to release milk-induction hormones such as oxytocin. 4. Check postpartum blood glucose levels: Spontaneous blood glucose level at and following delivery may influence energy and lactation hormone levels. Have regular meals and keep glucose checked as recommended. 5. Recharge and rehydrate: Don't forget water, protein meals, and nutritious fat. 6. Emotional support: Worry and doubt turn into an anxiety loop that spoils the milk flow. Have a strong support system that doesn't judge you for your breastfeeding struggle. Home remedies to increase milk production Though few studies are available, a majority of mothers find the following old remedies to work, suggests Dr Gupta: Moringa (Drumstick Leaves): Stimulates lactation and controls blood sugar levels. Fenugreek Seeds: Stimulates milk. But use with caution if you are diabetic as it will lower blood sugar levels. Oats, barley water, and garlic are other age-old lactation-stimulating foods. Also read: 6 foods can increase your breast milk production A word of caution: "Always consult your doctor before adding herbs or supplements, especially if you're managing blood sugar levels." The last word Gestational diabetes can have an impact on timing and amount of milk. Most women with GDM (Gestational Diabetes Mellitus) do indeed go on to breastfeed successfully too.

Having eggs just two times a week can help boost brain health and prevent THIS major disease
Eggs have always been considered a superfood, but research on them being high in cholesterol (through the yolk) has always kept high risk individuals away from them (heart patients, high blood pressure etc). However, now a study says that moderate consumption of eggs (2 or more) weekly reduces the likelihood of developing Alzheimer's dementia. Let's take a look... A research study published in The Journal of Nutrition demonstrated that older adults who regularly ate eggs, had 47% less chance of developing Alzheimer's dementia as compared to people who consumed eggs less frequently. This basic dietary information has proven to be an effective method for maintaining brain health, as well as delaying the onset of this destructive neurodegenerative condition. What does the study say The research study monitored 1,000 older adults aged 81.4 years on average, before they developed dementia. The research participants documented their dietary habits including egg consumption, while researchers tracked them for almost seven years on average. During this duration 27% of participants received an official Alzheimer's dementia diagnosis. The analysis controlled variables including age, together with physical fitness levels, education background, genetic tendencies and eating preferences, to establish the relationship between eggs and reduced risk. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like New Singapore Spots Raising the Bar Epicure Asia Read More Undo Protect the brain The documented reduction in risk stems from eggs' nutritional elements particularly choline, because this essential brain nutrient serves as the key factor. The brain produces acetylcholine through this nutrient, which plays a role in maintaining memory along with cognitive functions. Researchers found that choline intake from eating eggs explained 39% of the protective effect, which links egg consumption to Alzheimer's disease prevention. The brain benefits from egg consumption because they contain omega-3 fatty acids that reduce inflammation, while also providing lutein which fights oxidative damage that causes cognitive decline. Biological proof The examination of brain autopsy samples from 600 deceased subjects, showed that people who ate eggs regularly, displayed fewer Alzheimer's-related amyloid plaques than individuals who ate eggs less frequently. The scientific evidence supports the protective benefits of eggs on the brain through biological testing. What is Alzheimer's Alzheimer's disease stands as the primary dementia type, which advances through progressive memory deterioration and cognitive deterioration along with behavioral transformations. Alzheimer's disease affects millions of people worldwide today, with projections indicating substantial increases in aging demographics. The identification of preventable methods that people can easily apply through their regular eating habits becomes essential. Good for all Eggs function as an easy-to-implement brain health solution because they are inexpensive and accessible to everyone, while delivering essential brain nutrients in a highly absorbable form. The brain-supporting properties of eggs make them different from other brain-healthy foods, because people can easily add them to their regular meals without making significant dietary adjustments. Cholesterol concerns Recent research demonstrates that moderate egg consumption (two or more eggs per week) presents no health risks for most people, and delivers numerous health advantages that surpass previous dietary cholesterol-related worries. The protective effects of eggs depend on how people combine them with other foods in their diets. Some research studies have demonstrated that the protective benefits of eggs in reducing dementia risk depend on the specific dietary choices made by individuals. Research conducted on Mediterranean dietary patterns showed that egg consumption lowered dementia risk primarily among people, who followed a Mediterranean diet less consistently. The brain-healthy value of eggs becomes more evident when used alongside other brain-protective foods. Balance it out Experts agree that people seeking to enhance brain health and prevent dementia, should focus on various nutrient-dense foods along with eggs which include leafy greens containing lutein and fatty fish, with omega-3s, nuts and seeds with healthy fats as well as whole grains.

Walking daily may protect your brain from Alzheimer's, reveals 10-year study
If you've been looking for a reason to lace up your shoes and hit the pavement, a recent long-term study may be the motivation you need. Walking daily has been linked to a reduced risk of cognitive decline, especially for those with a genetic predisposition to Alzheimer's disease. The effects of walking extend beyond mere physical exercise; they also have a positive impact on brain health(Unsplash) The findings are based on a comprehensive study published in the journal JAMA and presented at the Alzheimer's Association International Conference, which tracked nearly 3,000 participants aged 70 to 79 over the years. Researchers noted their daily walking habits and found that maintaining or increasing these habits led to improved processing speed and executive function, key aspects of cognitive health. Dr Cindy Barha, the study's lead author and an assistant professor at the University of Calgary, emphasised the importance of combating sedentary behaviour. She suggests incorporating short walking sessions throughout the day to break up long periods of sitting. What is Alzheimer's disease? Alzheimer's disease is a complex disorder that represents a severe form of dementia. It is characterised by the accumulation of harmful plaques in the brain, which disrupt communication between nerve cells and eventually lead to their death. As nerve cells deteriorate, individuals may encounter: Memory loss: Difficulty recalling recent events or personal experiences. Difficulty recalling recent events or personal experiences. Confusion: Disorientation, especially in familiar environments. Disorientation, especially in familiar environments. Personality changes: Noticeable shifts in behaviour or mood. Unfortunately, there is currently no cure for Alzheimer's, making prevention strategies increasingly important. What is the role of genetics in Alzheimer's disease? Genetic factors play a significant role in one's likelihood of developing Alzheimer's. "Notably, a gene variant known as APOE4 can make it more challenging for the brain to remove the plaques associated with the disease. Approximately 15% to 25% of the population carries this variant, which can only be identified through genetic testing," neurologist Dr Neha Kapoor tells Health Shots. How does Alzheimer's affect the mind and body? While the study didn't prescribe a specific walking routine, Dr Barha proposed that breaking up periods of inactivity with multiple short walks throughout the day can greatly benefit cognitive health. Walking recommendations Frequency: Aim for multiple short walking sessions throughout the day. Aim for multiple short walking sessions throughout the day. Consistency: Maintain a steady walking habit from year to year. Maintain a steady walking habit from year to year. Goal: A previous study published in JAMA Neurology suggested that walking approximately 3,800 steps per day can reduce the risk of dementia by 25%. Also read: Walking 7,000 steps is good enough, says new study What happens to the brain during Alzheimer's? The effects of walking extend beyond mere physical exercise. They also have a positive impact on brain health. Here are a couple of theories explaining how regular physical activity may promote cognitive function: Increased BDNF production: Exercise boosts the production of brain-derived neurotrophic factor (BDNF), a protein crucial for neuronal growth and connectivity. Dr Barha explains that muscular activity seems to release proteins that travel to the brain, enhancing BDNF levels.

Dr Barha explains that muscular activity seems to release proteins that travel to the brain, enhancing BDNF levels. Reduction in neuroinflammation: 'Physical activity may also mitigate neuroinflammation, a common issue in Alzheimer's patients. The brain dispatches immune cells called microglia to clear away plaque, but chronic inflammation can lead them to attack healthy cells as well. Regular exercise can improve the functioning of these microglia,' shares Dr Kapoor. Every step truly counts. Dr Christiane Wrann, another expert associated with the study, highlighted that it's never too late to begin an exercise routine. Whether you're a seasoned walker or a newcomer, the key takeaway is to find an activity you enjoy and stick to it. Tips for getting started:
