Why am I so tired the next day after having sex?
We will be responding to those questions soon in subsequent posts but for now,continue reading below to find out why you feel weak after sex.
After sex, many couples find themselves feeling tired or sleepy. It’s all perfectly natural, and happens due to a number of biological and psychological reasons:

Hormonal Release
There are a whole bunch of hormones generated from sex, including;
Oxytocin (the bonding hormone)
Dopamine (the pleasure hormone)
The Prolactin (The thing that makes you feel all sleepy and calm post cum)
All of that creates a feeling of surrendering that can feel like vulnerability, at times.
Energy Consumption
Beyond that, sex is a cardio-vascular workout on a scale of light to moderate exercise.
It is found that in 30 minutes of intercourse men burn 100-150 calories and women burn 70-100 calories.
This energy loss can cause fatigue, especially if you’re already tired or haven’t eaten well.
Emotional Intensity
Good sex isn’t something you simply do, it requires a certain amount of mental attention and emotional investment, and also physical effort. Somehow the post-coital emotional crash is generally just a prolonged sense of relaxation that can be labelled as ‘weakness’.
Lack of Sleep or Stress
If someone is already fatigued, dehydrated or stressed out, feeling weak after sex will feel worse.
Example:
A 32-year-old night shift worker presented with postcoital fatigue. It was actually because his interrupted sleep cycle and dehydration made post-sex fatigue way worse when he was looked at by doctors, it transpired.
