What are those measurements? EASY: drink plenty of liquids and rest.

There is no contraindication for athletes to donate blood since donation does not pose health risks.

However, it’s advisable not to resume high-demand exercises immediately, but rather to apply medium intensity.

For example, running after donating blood is not recommended.

In the same direction, it is also not recommended to participate in highly demanding competitions immediately. 

The best is to wait a few days or even a couple of weeks.

    As someone with a family member who has benefitted from donated blood I can vouch on how lifesaving this procedure is. I make it a point to donate blood once a year nearing my birthday, just as a reminder to give back and help out someone who might need it more. I never knew though the kind of food that we could eat that would benefit the recovery process more so I super appreciate how you’ve gone into detail about that here. I am scheduled to make a donation next month! Thank you so much for discussing a topic that needs to be raised up more, it will save more lives.
