What does high cortisol feels like and how does it impact the brain and body?
Often dubbed as 'stress hormone,' cortisol is your body's natural alarm system, often kicked in when you are struggling to meet a deadline or when you are stuck in bad traffic. Cortisol helps us survive but when stress overpowers us, cortisol can go from helpful to harmful really quickly, wreaking havoc on your body, brain and mind. Let's break down what high cortisol actually feels like and how it could silently damage our mood and gut health, likewise.
What does cortisol do to your body and brain?
It usually starts with a racing heart, shaky hands, and uneasy feeling in your chest, during any stressful work. Maybe to some, they are just 'nerves' speaking but science suggests that this is something deep—your cortisol level are likely spiking up and your body is feeling the impact.
Back in 2019, a study was published in the
National Library of Medicine
offers fresh insight into this hormonal rollercoaster. The research further observed a group of young adults during a period of intense academic session, the results were shocking!
Salivary cortisol levels rose tenfold on the day of the exam compared to a normal day.

Cortisol and balance
?
The study revealed that elevated cortisol wasn't just making participants feel anxious — it was literally throwing them off balance. Both dynamic balance (our ability to move and stay stable) and static balance (our ability to stay still without falling) were significantly impaired during high-stress periods.
In some cases, performance on balance tests dropped by nearly 50%. It actively interferes with how our brain and body coordinate movement, maintain posture, and react to physical stimuli.
That means the next time you feel clumsy or off-center during a stressful moment, it's not all in your head — your hormones may actually be to blame.
What are the symptoms of high cortisol?
High cortisol can start with a range of symptoms. Some of them include:
Acne
Weight gain
Easy bruising
Flushed face
Severe fatigue
High blood pressure
Headache
What causes high cortisol levels in the body?
Chronic stress
The most common cause of high cortisol in the body.
It can be triggered by work pressure, relationship issues, academic stress or unresolved grief.
Sleep deprivation
Lack of quality sleep confuses the body's natural cortisol rhythm, leading to sustained high levels.
Poor diet
High amounts of sugar, processed foods and excessive caffeine can spike cortisol.
Alcohol and substance use
Regular intake of alcohol and some substances interferes with adrenal function and disrupts cortisol balance.
High cortisol is a silent sleep disruptor, often caused by stress, poor sleep and lifestyle choices. It impacts our mood, memory, and physical health. Recognizing the signs early and making mindful changes in your lifestyle can restore balance and protect long-term well-being.

State to administer anti-filariasis drugs to 1.27cr residents from Aug 10
Ranchi: To eliminate lymphatic filariasis from state, the department of health, medical education and family welfare will roll out the second round of Mass Drug Administration (MDA) from August 10, targeting over 1.27 crore people across 80 identified blocks in nine districts. The round of MDA will include the administration of three medicines — DEC, Albendazole, and Ivermectin. Additional chief secretary of health department, Ajoy Kumar Singh said, "Anti-filariasis medicines are not just distributed but consumed in the presence of trained health workers to ensure efficacy. Make people aware about the importance of anti-filariasis medicines to stay safe from the disease." Singh appealed to departments such as Education, ICDS, Panchayati Raj, Urban Development, PHED, and Livelihood to cooperate actively in the MDA campaign. State programme officer Dr Birendra Kumar Singh said, "Every eligible individual will be reached. The MDA hinges on detailed micro-planning, community awareness, and strong monitoring. Review meetings will be held daily at district and block levels, with a state-level assessment during the campaign to ensure proper implementation. If the community consistently takes the prescribed anti-filarial medicines annually for five years, the disease can be eliminated from the state. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Top 15 Most Beautiful Women in the World Undo " Moreover, the state is also proactively implementing the STOP Diarrhoea Campaign, running from July 1 to August 14, aiming to prevent child deaths due to diarrhoea.

Teen treated for rare and complex spinal condition
Mangaluru: A 13-year-old girl was successfully treated for a rare and complex spinal condition at the AJ Institute of Medical Sciences. The girl was diagnosed with Klippel-Feil Syndrome (KFS), a rare condition in which the bones in the neck are fused. This led to a short, webbed neck, limited neck movement, uneven shoulders, and a scoliotic spine. Her physical growth was also affected, and she lived with visible deformities for years. After detailed tests and investigations, the team of orthopaedic surgeons, led by Dr Sudeep Shetty and Dr Dheeraj Kumar, and paediatric specialists at the hospital discovered multiple abnormalities—fusion of the neck bones, an abnormal bone in the lower spine (hemivertebra), and a severely curved spine (scoliosis). Systemic conditions such as hypertension were also noted. She was diagnosed with type III Klippel-Feil Syndrome (KFS), the most severe form, often associated with other hidden health risks. In a single planned surgery, a multidisciplinary team comprising ortho spine surgeons Dr Dheeraj Kumar, Dr Hashir Safwan, Dr Pawan, and anaesthetists Dr TV Tantry, Dr Preetham, and Dr Nitu Renny performed spinal correction from the upper to lower back, removed the abnormal bone, and corrected her shoulder deformity. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like American Investor Warren Buffett Recommends: 5 Books For Turning Your Life Around Blinkist: Warren Buffett's Reading List Undo The surgery, which lasted for six to seven hours, was carried out under continuous neuromonitoring to ensure spinal cord safety. The child recovered without any complications and has already started her activities of daily living. Her journey from deformity to recovery stands as a testament to her courage and the medical team's expertise, said Dr Prashanth Marla, medical director at the hospital.
