Water is the key for many of us!
A brand new study found that people with a low daily fluid intake (under 1.5 liters) had a 50% higher cortisol response to a stressful situation than those who met recommended daily intake levels.
This phenomenon is linked to the body’s water-regulation system, as dehydration can increase the release of vasopressin, a hormone that affects both water balance and the brain’s stress-response center, amplifying the cortisol response.
High cortisol levels can lead to increased blood sugar and fat storage, especially around the abdomen. It also interferes with the body’s use of insulin.
Chronic high cortisol is also linked to high blood pressure and can contribute to heart disease by causing artery constriction and plaque buildup.
Cortisol suppresses the immune system by reducing white blood cell activity, making you more vulnerable to infections.
High cortisol also causes muscle weakness by breaking down muscle tissue and can even lead to bone density.
High cortisol can also result in fragile skin that heals slowly and can worsen acne.
You may also experience mood swings, irritability, anxiety, depression, difficulty concentrating and decision making, disruption of sleep-wake cycle leading to chronic fatigue and insomnia.
Individuals with lower fluid intake may not feel thirstier than their well-hydrated counterparts, but their bodies will show the affects of dehydration, such as more concentrated urine, fatigue, skin issues, confusion, rapid heartbeat and more.
The cost of dehydration is high and your body is paying the price! Aim for at least 1.5 liters of water a day and be sure you are taking sufficient amounts of essential electrolytes to ensure proper hydration. Electrolytes are needed EVERY DAY not just during sick recovery!
