On BBC Radio 4 today (29.6.2022) "Just one Thing with Michael Moseley" was very interesting. It is only 15 minutes long.
It describes the various benefits to eyes, joints and mood by taking short breaks throughout the day. A few minutes every 1/2 hour or so if possible actually makes people more productive. It lowers cortisol levels and benefits eye health.
Going outside in the breaks is also beneficial .
The programme is available on the BBC website, or it is repeated on BBC4 at 8.45pm today.
After this programme tonight at 9 pm is a very informative programme "A thorough examination with Drs Chris and Xand " about the results to our health of eating ultra processed foods (most of the food eaten in the UK !)
Best wishes
