Health experts are increasingly highlighting how everyday habits formed in early and mid-adulthood can significantly influence long-term wellbeing. In a recent advisory shared via an Instagram post dated May 4, Dr Saurabh Sethi, a gastroenterologist and hepatologist trained at Harvard and Stanford, outlined key lifestyle changes that may help prevent future chronic diseases. He noted that symptoms such as bloating, fatigue, and low energy are often early signals of deeper health imbalances rather than isolated or temporary discomfort.
One of the primary areas of focus, according to Dr Sethi, is sleep quality. He explained that sleep plays a critical role in regulating hormones, memory, metabolism, and emotional stability. Chronic sleep deprivation, he warned, has been linked to serious conditions such as obesity, depression, and cardiovascular disease. Alongside sleep, he emphasised strength training as an essential long-term habit, stating that maintaining muscle mass supports healthy ageing, improves metabolism, and helps preserve bone density.
Dr Sethi also highlighted stress management as a crucial but often overlooked health factor. He noted that persistent stress elevates cortisol levels, which can increase inflammation in the body and raise the risk of heart disease, weight gain, anxiety, and hormonal imbalance. In addition, he stressed the importance of protecting metabolic health through balanced nutrition, reduced consumption of ultra-processed foods, regular physical activity, and consistent sleep patterns to lower the risk of diabetes and related conditions.

Beyond physical health, the doctor pointed to the importance of emotional and cognitive wellbeing. Strong personal relationships, he said, are among the most powerful predictors of long-term health, as they help reduce stress and improve mental resilience. He also encouraged regular reading, explaining that mental stimulation supports focus, learning capacity, and may help reduce the risk of cognitive decline and dementia over time.
Dr Sethi further advised incorporating daily movement into routine life, noting that the human body is designed for regular physical activity. Consistent movement supports heart health, energy levels, and emotional balance, while also reducing the risk of chronic diseases. He also cautioned against alcohol consumption, stating that it affects sleep quality, liver function, brain health, and recovery, and that no completely safe level of intake has been clearly established.
Concluding his guidance, Dr Sethi emphasised that waiting for symptoms to appear often means preventive opportunities have already been missed. He stressed that small, consistent lifestyle choices made between the ages of 25 and 45 can compound over time, significantly shaping long-term health outcomes and reducing the risk of serious disease later in life.
