It is true and I think everyone should agree with this that it is a fact if everything is done when we are in a situation and condition tired due to other things then usually the results of our performance will not be maximized, although gambling depends on luck which makes me want to say that no matter if you are tired the name of victory can happen when you are lucky, but obviously however tired conditions will greatly affect decision making where there is a high probability for you to experience excessive emotions due to the atmosphere of the brain and mind being tired because of other things which ultimately makes you think of doing some aggressive actions based on frustration and desperation.
This is the importance of being able to manage and think rationally, which means that by having a healthy and rational mindset, I think it is small for you to force the situation just to gamble and most likely you will prefer to rest instead of gambling.
Gambling puts players into fatigue, rest eliminates it. When a person is tired, he's not meant to gamble. As he needs energy to gamble. Sleeping helps the brain to think strongly of something. When tired a player would be surprised at the type of blunder he makes in his game. Hence, it's crucial for a gambler to always be in his complete state of mind whenever wagering his funds. It happens in any other activities like reading or writing. When a tired person wants to type on the computer, he could be long pressing a particular key for a few minutes while dozing off. He'd only realize his mistakes like Op when awake. Although, those players who barely have enough time to gamble due to their work schedule are required to craft few hours after resting and gamble. Playing excessively adds no positive meaning to a gambler's journey. Hence, there is no need for a player to stress himself trying to gamble more when he actually needs rest.
