Stress

We can all feel tired from time to time, and it’s perfectly normal; it just means our bodies need rest. You can spend the whole day on your feet and be tired by the evening. You can also spend an entire day sitting with your books and end up even more tired than from physical exertion because our brain is the most energy-consuming organ in the body. Stress can also make you tired; it consumes a lot of your energy.

Cortisol is a steroid hormone produced by the adrenal glands. It is also known as the stress hormone, as it is released in response to stressful situations along with other hormones like adrenaline and noradrenaline. Cortisol helps the body adapt to stress and function normally in high-pressure situations.
