Experts Warn That Disrupted Body Clocks Could Harm Heart Health
Heart health specialists are warning that disruptions to the body’s natural circadian rhythm—the internal 24-hour clock that governs sleep, hormones, digestion, and body temperature—can have serious health consequences, including a higher risk of heart disease and diabetes.
A new scientific statement from the American Heart Association (AHA) highlights growing evidence that irregular sleep, eating patterns, shift work, jet lag, and nighttime light exposure can interfere with the body’s ability to regulate metabolism, blood pressure, and hormones. These disruptions, experts say, may contribute to obesity, hypertension, and type 2 diabetes.
“Regular interruptions to the body clock are much more than simple inconveniences like staying up too late or waking up too early,” said Dr. Kristen Knutson, an associate professor of neurology at Northwestern University in the United States. “Aligning our daily behaviours—when we sleep, eat, and move—with our internal clock is important to support optimal cardiometabolic health.”
To help people realign their body clocks and improve wellbeing, heart health experts have outlined several practical steps:
1. Get light in the morning, avoid it at night
Light is the main environmental signal that helps the brain regulate the circadian rhythm. Experts recommend getting natural daylight early in the morning to improve alertness and mood. At night, however, even small amounts of light—especially from screens—can suppress melatonin, the hormone that promotes sleep.
2. Keep a consistent sleep schedule
Going to bed and waking up at the same time each day, including weekends, helps maintain the body’s internal rhythm. The AHA notes that irregular sleep patterns have been linked to obesity and metabolic disorders, even in people who get sufficient sleep overall.
3. Eat earlier in the day
Late-night meals or irregular eating patterns can disrupt the body’s metabolic rhythm, particularly in organs like the liver and pancreas. Research suggests that eating earlier, such as having breakfast before 8 a.m., is associated with better heart and metabolic health.
4. Time your exercise
While the best time to work out varies from person to person, exercise timing can influence blood pressure, glucose control, and sleep quality. Morning or afternoon workouts may help advance the body clock, while evening exercise can delay it.
5. Monitor your rhythm
Although the circadian rhythm can be difficult to measure directly, wearable devices that track heart rate and skin temperature may help individuals understand their natural patterns.
Knutson said it’s time for both individuals and healthcare professionals to pay more attention to the body’s internal clock. “Everyone has an internal clock, and it’s time we start listening to it,” she said.

Global Mental Health Cases Near 1.2 Billion as Anxiety and Depression Drive Sharp Worldwide Rise
A major global analysis has found that mental health conditions have surged to an estimated 1.2 billion people worldwide, driven largely by steep increases in anxiety and depression over the past three decades.
The findings, published in The Lancet as part of the Global Burden of Disease Study 2023, show that the number of people living with mental disorders has almost doubled since 1990, marking a 95% rise. Researchers say major depressive disorder and anxiety disorders have seen even sharper growth, increasing by 131% and 158% respectively, making them the most prevalent mental health conditions globally.
The report describes mental illnesses as widespread conditions that create long-term disability and significant human suffering. It also highlights broader consequences for economies and public services, including reduced productivity, lower workforce participation and increasing pressure on health and welfare systems.
Researchers estimate that in 2023 alone, around 620 million females and 552 million males were affected by mental health conditions. While the overall burden is rising across both sexes, the study points to notable differences in the types and prevalence of disorders.
Among women, depression and anxiety were the most commonly reported conditions, alongside higher rates of eating disorders such as anorexia nervosa and bulimia nervosa. The report links this disparity to a mix of biological, social and structural factors, including exposure to domestic violence, sexual abuse, gender inequality and reproductive health-related changes.
In contrast, neurodevelopmental and behavioural disorders, including attention deficit hyperactivity disorder (ADHD), conduct disorder and autism spectrum conditions, were more frequently diagnosed in men.
Teenagers aged 15 to 19 were identified as the group experiencing the highest mental health burden globally, raising concerns about early onset of conditions and insufficient preventive care for young people.
The study identifies several key risk factors associated with mental illness, including childhood sexual violence, bullying and intimate partner violence. These factors are strongly linked to conditions such as depression, schizophrenia, bipolar disorder and anxiety disorders. However, researchers note that such exposures have remained relatively stable over time and account for only a portion of the overall rise.
According to the authors, broader drivers are likely contributing to the increasing prevalence of mental disorders. These include genetic and biological influences, poverty, inequality, and the growing impact of global crises such as armed conflict, pandemics, natural disasters and climate-related stress.
While mental health conditions have long been a leading cause of disability worldwide, the report warns that the situation is worsening. At the same time, health systems have not expanded services at a pace matching demand.
The authors caution that the gap between rising need and limited access to care is becoming more pronounced, leaving millions without adequate treatment or support.
