Cortisol, often called the “stress hormone,” has become a popular target for wellness discussions online. Social media trends frequently blame cortisol for issues like weight gain, fatigue, and poor mood, but should you really be concerned about your levels?
What Is Cortisol and Why Do We Need It?
Cortisol is a hormone produced by the adrenal glands in response to stress. It helps regulate metabolism, blood pressure, immune responses, and circadian rhythms. When faced with a stressor, cortisol ensures the body has enough energy to respond, making it essential for survival. “It’s an adaptive hormone critical for both acute stress response and recovery,” explains Rajita Sinha, a neuroscientist at Yale School of Medicine.
Understanding Cortisol Levels
Cortisol follows a natural cycle, peaking in the morning to wake us up and declining in the evening to prepare for sleep. Short-term spikes are normal and beneficial, helping the body manage immediate stress. However, chronic elevation can lead to weight gain, sleep disturbances, and mood disorders such as anxiety and depression.
When to Be Concerned
Consistently high cortisol levels may contribute to metabolic issues and mental health concerns. On the other hand, excessively low levels could indicate adrenal dysfunction, leading to fatigue, weight loss, and low blood pressure. If you’re experiencing persistent symptoms, endocrinologists recommend seeking medical advice rather than relying on internet trends.
The Bottom Line
Cortisol is essential, and its fluctuations are normal. If you suspect an imbalance, consult a healthcare provider rather than falling for social media-driven cortisol panic.
