The “first night effect” (FNE) is a well-known phenomenon in polysomnographic (PSG) recordings characterized by decreased total sleep time, lower sleep efficiencies, reduction in REM sleep, and longer REM latencies on the first night of testing (Agnew, Webb, & Williams,1966).
The first-night effect in sleep polysomnographic studies is usually considered to last for one night. However, a few observations have indicated that variables associated to rapid eye movement sleep take longer to stabilize.

After an orgasm, the body releases hormones. View Source , like oxytocin and prolactin, that can induce pleasant and relaxing feelings.

According to health experts, as soon as a man reaches orgasm, his body chemistry changes. This happens when the biochemical prolactin is released, it makes him tired and he tends to sleep after an intimate session.
In general, each cycle moves sequentially through each of the 4 stages of sleep: wake, light sleep, deep sleep, REM, and repeat.
During sleep, your parasympathetic system controls your body, and your heart does not work as hard as it does when you are awake. During REM sleep and when waking, your sympathetic system is activated, increasing your heart rate and blood pressure to the usual levels when you are awake and relaxed.
There's a name for this phenomenon: It's called a hypnic jerk or sleep start. It's a sudden increase in muscle activity that happens to just about everybody and can be quite literally startling, though the intensity depends on the person, says Carl Bazil, M.D. Ph.
So does snoring mean deep sleep? No it doesn't. REM sleep becomes very fragmented and interrupted by snoring so snorers aren't able to reach deep sleep. Only frequent, prolonged and severe snores mean possibly obstructive sleep apnea.
The SCN is located in the hypothalamus. The SCN is sensitive to signals of dark and light. The optic nerve in your eyes senses the morning light. Then the SCN triggers the release of cortisol and other hormones to help you wake up.
