The hormone cortisol

Long-term stress and strain on the body, due to factors such as excessive worrying, lack of sleep, and overworking for extended periods of time, can impair your immune system.

Key takeaways
  1. 01Chronic stress keeps cortisol elevated — this breaks down muscle, skin, and immune defenses
  2. 02Cortisol follows a daily rhythm — highest in the morning, lowest around 4 am
  3. 03Prioritize sleep and recovery to prevent prolonged cortisol release from damaging tissue
  4. 04Elevated cortisol over time raises abdominal fat, blood sugar, and insulin resistance risk
  5. 05Cortisone injections mimic cortisol — repeated high doses degrade local tissue the same way

Long-term stress and strain on the body, due to factors such as excessive worrying, lack of sleep, and overworking for extended periods of time, can impair your immune system. The body experiences prolonged cortisol release to cope with the stress, which can be detrimental in the long run. Cortisol is a stress hormone produced in the adrenal glands that, together with the stress hormone adrenaline, helps cope with acute stress situations. It acutely enhances both mental and physical performance. However, when cortisol is produced in elevated levels for extended periods, it becomes destructive to the body.

Cortisol is necessary and vital as it regulates the body’s water, salt, fat, carbohydrate, and protein balance. It affects blood glucose levels and maintains blood pressure. Its levels vary in a circadian rhythm, with the highest levels in the morning to help us wake up and the lowest around 4 am. Cortisol also plays a vital, natural role in regulating the immune system, helping to dampen inflammatory processes, fight infections, and promote healing.

During periods of stress, the body produces extra cortisol to help cope with the situation. Cortisol breaks down proteins, fats, and sugars, breaking down tissues to raise blood sugar levels and increase the supply to the brain and muscles. If this process continues for a long time, it can have negative consequences and cause damage to our bodies. We may experience:

Sleep problems

High blood pressure

Muscle wasting

Hair loss

Fragile skin and mucous membranes

Impaired wound healing

Increased abdominal fat

Impaired thyroid function

Impaired cognitive ability

Most importantly, a weakened immune system which can lead to high blood sugar levels, insulin resistance, and type 2 diabetes.

Cortisone is a synthetic drug that is similar to cortisol and has the same effects. High and prolonged doses of cortisone treatment have negative effects on the body, just like cortisol. Depending on where the treatment is applied, it often affects the tissue locally. Cortisone is usually used to suppress inflammation.
