Your health matters to you. You eat the right things. You work out regularly. You get the right amount of sleep. But when it comes to working out and sleeping, it can be hard to know if sleeping right after a workout provides benefits or hurts your health. If you have insomnia, a disorder that prevents you from achieving adequate sleep, working out before you go to bed might encourage sleepiness.
If you have the chance, try to exercise hard the day before your sleeping marathon. There's nothing like going to bed with the feeling of having done a hard day's work. Physical exercise is well-known for its effect of promoting good sleep. In fact, exercise is even a frequent treatment for clinical cases of insomnia.
