Golden Exercise Time is out! Did you choose the right one? Two major studies found that exercising at 8-10 a.m. reduced the risk of cancer by 27% and stroke by 17%

Exercise can prevent many cancers, but did you choose the right time of day? Disturbing the body's circadian rhythm increases cancer risk
.
Recently, two studies found that exercising early in the morning seemed to prevent breast and prostate cancer
better than exercising later in the day.
Nocturnal exercise appears to have a moderate protective effect
against prostate cancer.
Morning physical activity was associated with a reduced risk of cardiovascular disease, regardless of overall physical activity, highlighting the potential importance
of temporal activity in cardiovascular disease prevention.
Overall, exercising at 8-10 a.
m.
can not only reduce cancer risk by 27%, but also stroke by 17%.

Exercise and cancer

In this study, the researchers observed that the overall protective effect of recreational and home physical activity on cancer may vary
depending on the time of day of the activity.
Studies have found that early morning activity may be more protective than morning and afternoon activity for the potential risk of breast and prostate cancer
.
The findings of evening activity differed, with only moderate protection against prostate cancer observed
.
There is no consistent pattern between different time types, and differences
are observed in tumor subphenotypes.

Studies estimated odds ratios (OR) and 95% confidence intervals (95% CI)
for different duration of activity.
Early morning (8-10 am) activity was protective against breast (OR = 0.
74, 95% CI = 0.
48 to 1.
15) and prostate cancer (OR = 0.
73, 95% CI = 0.
44 to 1.
20) compared with no physical activity; The combined meta-OR for the two cancers was 0.
74 (95% CI = 0.
53 to 1.

No effects of breast or prostate cancer were observed during the late-morning to afternoon activities, while protective effects were also observed for nocturnal activities of prostate cancer only (OR = 0.
75, 95% CI = 0.
45-1.
24).

For both cancers, the protective effect of early morning activity is more pronounced
in the mid/evening period.

Obesity is associated with breast and prostate cancer and may be an additional pathway
associated with physical activity and physical activity time in relation to reduced cancer risk.
The route is unclear and may be related to
circadian hormonal patterns.
The researchers observed that people who exercised in the morning experienced higher weight loss and lower total calorie consumption
compared to exercising at other times of the day.
However, adjusting for BMI and total calorie consumption did not change the cancer risk pattern
for time categories in our analysis.

Overall, the findings suggest that time of day is an important aspect of physical activity and may enhance physical activity's protective effect
against cancer risk.
In future studies, the effect of physical activity time on cancer risk should be examined and activity patterns assessed in more detail, including occupational activity
.
More evidence is needed on the biological mechanisms by which time of physical activity affects circadian rhythms, and further research into the potential mechanisms
underlying the potential effect of timing on cancer risk should be conducted.
