What do sex, stress and sleep have in common?

Although they may seem unrelated at first glance, they have more in common than you might think. They also all affect your immune system.

It has been proven to be sufficient and of good quality sleep improves your sex life, and vice versa can also sex improves the quality of your sleep! But that’s not all, because the hormone of happiness is secreted during sex, which reduces the release of cortisol, a stress hormone. And as we said in the introduction, they all affect your immune system and thus increase or decrease the chance that you will get sick.

Don’t think that you don’t have to worry about a healthy immune system in the summer because of the warmer weather. High temperatures outside and low in air-conditioned rooms, as well as exposure to various ‘blowing’ devices, create an excellent environment for the development of colds, and you can also be threatened by a stress-related illness on holiday.


The study found that students who had sex once or twice a week had 30% vem immunoglobulin A, a blood protein that helps protect against colds, in their blood than those who did not have sex or had it less often.


A 2015 study found that people who slept less than 6 hours a night were four times more likely to fall ill when exposed to the virus than people who slept seven hours or more. When you sleep, the number of T cells that fight viruses in the bloodstream increases.


Stress not only makes you more susceptible to infections, but also reduces your body’s ability to fight inflammatory processes, resulting in longer recovery. When you are chronically stressed, your body increases cortisol production, and this can have a negative effect on your immune system.

Work-related stress, however, can also affect you when it’s time to take a break. Do you often get sick in the first days of your vacation? Pressure stimulates your immune system and when you are under stress at work due to demanding work or approaching deadlines, the body knows it should not get sick. When it comes time to rest, the pressure drops and your body takes this as a signal that it may get sick.
