When stress increases, almost all organs and functions of the body intervene, it affects the brain, nervous system, heart, blood flow, hormonal levels, etc. This causes cardiovascular diseases, rheumatoid arthritis, migraines and extreme pain in neck and back muscles, baldness, asthma, nervous tics, sexual impotence, irregularities in the menstrual cycle, colitis and gastritis, loss or increase of appetite, overweight, acne, and cellulite.
In stress situations we release cortisol, this hormone raises blood glucose levels to increase energy so our brain can react quickly to a dangerous situation, the problem is that most stress situations (overthinking, work, money) don’t need an immediate response from our body and our hormones unbalanced needlessly.
Cortisol has been linked to increasing abdominal fat which in addition to covering your abs it is also related with several health issues.
Cortisol prevents protein synthesis and increases the enzymes that break the protein, in other words it doesn’t let your muscles recover and pretty much "eats" them. Losing muscle mass slows our metabolism.
Stress can give us eating anxiety, we find comfort and distraction in food, it becomes a vicious circle that can easily make us accumulate extra pounds.
When we live in constant stress there is an imbalance of serotonin, dopamine and endorphins, this can produce cravings for carbohydrates, sweets and fatty foods.
People who are very stressed and busy often go with the mantra "No time for anything", and don’t make time to cook at home or exercise, and usually eat out and junk food. This combination is a combo to start gaining fat and health problems.
These does not mean that cortisol is "bad" in itself, it is a vital and necessary hormone, with specific important functions in our body. But, as with any other hormone, when it goes out of control has negative effects.
That is why it is important to take some time for ourselves, try not to think about the inconveniences of the day before bed, when facing a stressful situation take a deep breath and think calmly. Listen to your favorite music, read a good book, meditate, let go of what you can't control, work out regularly, and try to keep yourself relaxed, or at least avoid letting stress control your life.
