Lethargy refers to a state in which you do not want to do anything, your body feels heavy, and everything feels bothersome and meaningless.

There are many causes of lethargy, and if there is no underlying physical illness, it can occur due to psychological issues.

It can also develop when you are under extreme stress, have had experiences of failure, or have accumulated fatigue due to excessive workload.

Lethargy can also occur temporarily in summer, and you may experience these symptoms due to high temperatures, humidity, and physical exhaustion.

In summer, people sweat a lot, and if you do not drink enough water at that time, dehydration can occur. A lack of fluids can cause reduced physical strength and lethargy.

In addition, because of the high temperatures in summer, a lot of energy is needed to regulate body temperature, which can make you feel worn out and can be a cause of lethargy.

The main symptoms of lethargy include a sense of futility, fatigue, and reduced motivation. If lethargy is left unaddressed for a long time, it can also lead to depression.

You may no longer feel much interest in things you once enjoyed, have trouble focusing on something, or feel physically heavy every day.

Also, if you cannot even start planned tasks because you lack motivation, negative thoughts fill your mind, and you feel like you do not know the meaning of life, lethargy may be the cause.
