Answer:
30 min before you go back in
Step-by-step explanation:
"wait at least 30 minutes after eating before you swim is based on the idea that after a big meal, blood will be diverted away from your arms and legs, towards your stomach's digestive tract. And if your limbs don't get enough blood flow to function, you're at risk of drowning."
"No matter what time of day you choose to exercise, make sure to plan your workout two to three hours after your meal. Going overboard with too much food right before a workout will leave you feeling sluggish and can lead to stomach discomfort. The last thing you want is your workout habits to hinder your digestion process."
