Decreases Cortisol
A positive side effect of our bodies being allowed to cool at night is
that it lowers cortisol levels. Cortisol can cause serious problems
ranging from disrupted sleep cycles to serious weight gain.
Comfortable in Your Own Skin
We spend a lot of time trying to hide our imperfections. We dress our
bodies in the "right" clothes to make us feel more secure about our
bodies however, sleeping naked will make you fully aware of your body
and therefore, you'll feel more comfortable with it.
Happy Together
If you sleep naked with your partner, that skin-on-skin contact will
release some oxytocin. Oxytocin makes you happier, reduces social
anxieties and helps with overall satisfaction.
