Hi Lisa, welcome to Gransnet. As you get older do you simply not need as much sleep? I'll be honest, I feel like a need more and I blame my lack of sleep (it's been years - possibly decades - since I got a full 8 hours) for my constant brain fog and lack of energy.
Also, what are the cognitive issues with lack of sleep? How do people like Maggie Thatcher survive on so little and still manage to be productive and coherent? I feel like my vocabulary completely deserts me if I haven't had decent sleep.
Hi Lynda, thank you for your question. It’s actually myth that you don’t need as much sleep as you get older – a 60 year old still has the same sleep needs as a 40 year old but it’s just sleep changes as you age, you get less deep sleep (which means your sleep is less refreshing) and you tend to wake more in the night too. When you are sleep deprived, it does affect you. People often find they feel foggy, find it harder to concentrate, struggle to retain information and feel more irritable, snappy and impatient.
Maggie Thatcher is a famous person who declared she needed very little sleep – there have been others too – but again, sleep is very individual, some of us function perfectly well on 6 hours sleep per night whereas some of us need nearer to 9 hours of sleep per night.
