airmattressHave an air mattress to blow up? Lots of party balloons to fill? An inflatable toy that needs pumping up? Or need a whole lot of breath for something else?

Save all the blowing for Week 3 of your cycle–the week right after ovulation.

Research shows that you exhale more breath on these days compared to the rest of your cycle.

As a result, you’ll fill up these air-filled objects faster.

Credit for the deeper exhales during your Week 3 goes to the combination of estrogen and progesterone, which make it easier to exert pressure on muscles that help your lungs expel air.
