The Best Times to Sleep (Circadian Rhythms)

In case you're pondering what the ideal circumstances are to take part in specific exercises, tune in to your body's circadian rhythms. Circadian rhythms are physiological, mental and behavioral changes administered by the body inside a 24-hour clock, They are influenced by ecological signals, for example, daylight, haziness and temperature.

Circadian rhythms

Circadian rhythms impact rest/wake cycles, hormone discharge, body temperature and other critical body functions, and as we get older these rhythms change. the National Sleep Foundation reports that in the mornings with exposure to light, the brain sends signals to raise body temperature and produce hormones like cortisol.

Cortisol

Cortisol is produced in response to stress as well as according to natural circadian rhythm cycles.It helps give us energy in the morning, and levels diminish throughout the day, the mind likewise reacts to light by deferring the release of other hormones like melatonin, which is associated with sleep and produced when we’re exposed to darkness.

Melatonin levels 

Melatonin levels rise in the evening and stay elevated throughout the night, promoting sleep. All this means that, based on age, there is a best time to be doing everything in our lives, like going to sleep and waking up, exercising, and even having a cocktail.

Sleep

Sleep is a naturally recurring state of mind and body, characterized by altered consciousness, relatively inhibited sensory activity, inhibition of nearly all voluntary muscles, and reduced interactions with surroundings

the melatonin in our bodies starts decreasing as we get older so we start waking up earlier and earlier as age increases

According to The National Sleep Foundation, the recommended sleeping hour for adults is 7 to 9 hours and for older adults (65+) is 7 to 8 hours
