Love coffee? Here's when too much caffeine starts hurting your health

For most office-goers, coffee is the holy grail that powers them through deadlines and endless meetings. But is your caffeine fix secretly sabotaging your health? Business Standard spoke to Charu Dua, chief dietician and head of clinical nutrition at Amrita Institute of Medical Sciences and former chief clinical nutritionist at Max Super Speciality Hospital, Patparganj, to understand how that extra cup (or three) might be doing more harm than good, and what you can sip instead.
How common is excessive caffeine intake among office workers?
While many turn to coffee for an energy boost, over-relying on caffeine is worryingly common in high-stress workplaces. Dua highlights some tell-tale signs:
Withdrawal symptoms: Headaches, irritability, and fatigue when you skip caffeine
'If you're using coffee to mask poor sleep or chronic stress, it's a red flag,' she points out.
What are the health risks of too much caffeine?
The effects of too much caffeine go far beyond a racing heart or a jittery feeling. According to Dua, short-term impacts include:
Increased heart rate and palpitations
Anxiety and jitteriness
Digestive disturbances
Long-term effects can be even more serious:
Dependence, leading to withdrawal headaches and fatigue
Increased risk of anxiety and depression
Sleep disruption, which then feeds into a vicious cycle of caffeine dependence
'Excessive caffeine can significantly disrupt your mental and physical health if not moderated,' warns Dua.
How caffeine harms productivity, sleep, and mental health
Initially, caffeine can enhance focus and alertness, especially if you're sleep-deprived. But Dua cautions, 'Regular high intake can backfire, affecting your ability to sleep well, which in turn reduces productivity and mental clarity.'
Caffeine late in the day can cause insomnia and poor sleep quality, and for sensitive individuals, it can even worsen anxiety and depression.
Who should limit or avoid caffeine?
Dua points out that caffeine can be particularly problematic for:
Best healthy coffee alternatives for office-goers
Looking for ways to stay energised without the caffeine crash? Dua recommends:
'These drinks offer alertness without the jitteriness of coffee,' she adds.
How to quit caffeine without facing withdrawal symptoms
Quitting caffeine cold turkey is tough. Dua suggests a gentle taper:
Maintain a balanced diet to naturally boost energy levels
'Gradual reduction and mindfulness can make the process easier and sustainable,' she assures.
Health benefits of coffee: Why moderation matters
Absolutely, in moderation!
Dua shares that regular coffee consumption may actually reduce the risk of certain chronic diseases:
Liver conditions: Lower risk of cirrhosis and liver cancer
Hypertension: Moderate intake can help reduce blood pressure risk
Type 2 diabetes: Coffee drinkers show a lower risk profile
Parkinson's disease: Higher caffeine intake is linked with lower risk
But, and this is important, moderation is the golden rule. 'Mindfulness about how much and when you consume coffee is essential,' says Dua.
Coffee can be a wonderful pick-me-up, but guzzling cup after cup may quietly harm your health. According to experts, staying mindful of your caffeine habits, listening to your body, and embracing healthier alternatives can make all the difference in how you feel, both at your desk and beyond.

Odisha planning to include yoga in school curriculum, health schemes: CM

Odisha Chief Minister Mohan Charan Majhi on Saturday said the state government is taking initiatives to include yoga in the school curriculum and public health programme as this helps create a healthy, self-reliant and efficient India. Addressing a state-level programme on the occasion of International Yoga Day at Kalinga Stadium here, he said yoga is not just a physical exercise but something that keeps the body, mind and soul active. The programme, organised by Odisha's Sports and Youth Affairs Department, was attended by over 10,000 people, including ministers, lawmakers, bureaucrats, students, women and others. In Odisha, we are making yoga available to everyone. We organise awareness campaigns on yoga in schools, colleges, hostels and sporting centres. We can also include yoga in school curriculum and public health programmes, the chief minister said. Majhi said that the awareness programmes on yoga teach people to maintain a healthy life. Though yoga has been practised in India for many years, Prime Minister Narendra Modi ensured its international recognition after assuming charge as the PM in 2014, he said. Due to the PM's efforts, the United Nations declared June 21 as the International Yoga Day, he said. The chief minister said that yoga is "not just a physical exercise, but something that keeps body, mind and soul active". Yoga is a medium to attain physical, intellectual, mental and spiritual fulfilment. It is beneficial for human bodies," he said. The theme of this year's International Yoga Day is 'Yoga for One Earth, One Health', which highlights the deep connection between personal well-being and the health of the planet. "It shows how the ancient yoga practice nourishes not only the body and mind but also nature and promotes a harmonious lifestyle that respects all living beings," he said. On this occasion, the traditional Gotipu dance was performed by the culture department. Internationally acclaimed sand artist Padma Shri Sudarsan Pattnaik has created a sand sculpture of Prime Minister Narendra Modi performing Ustrasana (Camel Pose) on the Puri sea beach.

Neurogrit Gold opens new avenues for curing Parkinson's

Haridwar / Hyderabad: Novel research conducted by Patanjali's scientists on C. elegans confirms that the Ayurvedic formulation Neurogrit Gold not only helps improve memory loss caused by Parkinson's disease, but it also increases the lifespan; however, it does not hamper the growth and progeny of these organisms. This exemplary study has been published in the world-renowned Wiley's publication journal, CNS Neuroscience & Therapeutics. On this occasion, Acharya Balkrishna stated that in Parkinson's disease, not only does a person suffer mentally, but their social interactions also shrink significantly. But is there a way for such individuals to recover and resume their daily activities independently? Yes, indeed, it is possible! Acharya further stated that Neurogrit Gold is a remarkable fusion of our ancient wisdom, Ayurveda and modern science. This research demonstrates that if natural herbs are analysed through a scientific lens, they can bring revolutionary solutions to modern-day health challenges. Neurogrit Gold is a composition of natural herbs like Jyotishmati and Giloy, along with traditional Ayurvedic Bhasma such as Ekangveer Ras, Moti Pishti, Rajat Bhasma, Vasant Kusumakar Ras, and Rasraj Ras, all of which are considered beneficial for neurological disorders.
