How Much Exercise Does It Take to Boost Immunity?

Exercising may make our immune systems more than five times better at fighting infection. The immune-boosting effects may also be one of the reasons why it seems to help both prevent cancer and improve cancer survival.

"Exercise can potentially make our immune system 5x better at fighting infection..." - that's reason enough for me to keep moving!

Thank you, Dr Greger. 75 ys old, walk 45 mins daily on treadmill, do 45 mins floor and standing exercise daily. 6 hrs of Tai Chi and Chi Kung weekly.

The bare minimum needed is either :
a) 20 minutes of brisk walking 3 times a week.
b) 12 minutes of jumping jacks on a trampoline 3 times a week.

That is just the bare MINIMUM. Adequate would be twice that, plus some level of strength training with free weights.

Most elderly people have problems getting up off the floor. As a child you spend a lot of time on the floor, adults do not.
Doing yoga / stretching exercises on the floor can improve balance, mobility, flexibility and the ability to get up and down..
Just getting up and down to the floor in a controlled manner is difficult for many older adults.
Play with your children on the floor. Bend over, get down and pull weeds in your garden. Play with a pet on the floor.
The more effort you make to work on balance and flexibility will pay dividends as you age.

Please include the sample sizes of the studies presented, as these are a good proxy for assessing the statistical power of the studies presented. (Nutrition literature - especially older literature - often lacks sufficient statistical power).

Probably why hubs and I haven’t really been sick since we moved to SWFL, 11 years ago.

Study by Janet Lord of older long term exercisers showed preserved thymus function and immune function. Also better vaccine response. SO it might be that studies need to assess older people who have exercised for a longer period of time to gauge true effects.

What about over exercise? How much exercise will backfire, make you so tired and lower the immune response?

Not hating or anything but what is all the Christian spam in the comments?
