In Denmark, one of the least religious countries studied, 2,987 adults were followed through national registries. Attendance went with 30% lower mortality overall, but only in women, while hospital stays were lower only in men. A pattern that splits by sex like this is hard to explain with one mechanism.

biblical wellness
God designed us for rest, worship and each other. The research keeps noticing.
I am a biblical naturopath, so people ask me whether faith shows up anywhere in the health data. It shows up clearly in some places and not at all in others, and I would rather hand you both halves than sell you one.

the short version
what the research found
the headline numbers
-
In 74,534 women followed for two decades, attending services more than once a week went with a 33% lower death rate than never attending.
-
In 89,708 women, attending weekly or more went with a suicide rate about five times lower than never attending.
-
Across 148 studies and 308,849 people, those with stronger social relationships had 50% higher odds of surviving the follow-up period.
-
Across 69 studies, religious or spiritual life went with 18% lower mortality in people who started out healthy, and no difference in people who were already ill.
-
In 1,802 heart bypass patients, being prayed for by strangers made no difference to complications (52% versus 51%).
my honest bottom line
The most consistent signal is for showing up: weekly worship tracks with lower death rates, less depression and lower suicide rates in cohorts of tens of thousands of women. These are observational studies in mostly professional US samples, so people who attend may differ in ways no statistics fully remove, and the large trial of prayer by strangers found no difference.

where Scripture and the studies meet
“not neglecting to meet together, as is the habit of some, but encouraging one another”Hebrews 10:25 (ESV)
episynagōgē, the Greek word here, means a gathering together. It is not attendance as a box to tick. It is being gathered, on purpose, toward each other.
In 74,534 women followed for two decades, attending more than once a week went with a 33% lower death rate, and social support carried about a quarter of it. Li 2016
“The Sabbath was made for man, not man for the Sabbath.”Mark 2:27 (ESV)
shabbat comes from the Hebrew shavat, to cease or stop. Rest was given as a gift before it was ever measured, and it begins with stopping.
In 1,300 teachers in four countries, keeping a Sabbath went with less burnout. It is one survey at one point in time, so it cannot say which came first. Cheng 2023
“Test your servants for ten days; let us be given vegetables to eat and water to drink.”Daniel 1:12 (ESV)
zeroim, the Hebrew behind vegetables, means things that are sown. Daniel's request reads like a trial design: a ten-day test, a comparison group eating the king's food, and an outcome checked at the end.
In the modern 21-day Daniel Fast study, total cholesterol in 43 adults fell from 171 to 139 mg/dL. There was no control group, and HDL fell too. Bloomer 2010
“as the Lord has forgiven you, so you also must forgive.”Colossians 3:13 (ESV)
charizomai, the Greek for forgive here, shares its root with charis, grace. Forgiveness in this verse is given freely, the way it was given to us.
Across 53 results from 2,323 people, structured forgiveness programs raised forgiveness and eased depression and anxiety compared with no program. Wade 2014
what about prayer?
The largest trial of prayer by strangers, 1,802 heart surgery patients, found no difference in complications, and patients told for certain that they were being prayed for did slightly worse. Prayer was never meant to be a lab variable, and a trial cannot measure the One it is asking about. You still deserve to know it was tested, and what it found.

A review of 19 randomized gratitude studies with physical health outcomes. Self-reported sleep improved in 5 of 8 studies, physical symptoms in only 2 of 8 and inflammation markers in 1 of 2. Most studies had bias concerns, so the reviewers drew no firm conclusions about physical health.
Nurses' Health Study, 74,534 women followed from 1992 to 2012. Attending services more than once a week went with a 33% lower death rate than never attending, including lower heart disease and cancer deaths. Social support explained about 23% of the association and not smoking about 22%.
Among 89,708 women, attending once a week or more went with a suicide rate about five times lower than never attending. The association was stronger among Catholic women than Protestant women.
In 48,984 nurses, the women who attended most often and most recently had the lowest odds of new depression (29% lower). The arrow ran both ways: women who were already depressed were less likely to keep attending, and the authors modeled both directions.
Across 53 results from 2,323 people, structured forgiveness programs raised forgiveness more than no program (effect size 0.56) and more than other programs (0.45), with added changes in depression, anxiety and hope. Longer, one-on-one programs did better.

Across 148 studies and 308,849 people, those with stronger social relationships had 50% higher odds of surviving the follow-up period, across age, sex and starting health. Being part of a wider community mattered more than simply living with someone.
Pooling 69 studies of healthy people, religious or spiritual life went with 18% lower mortality, even after accounting for smoking, drinking, exercise, income, mood and social support. In 22 studies of people who were already sick there was no association. The part that carried it was organizational, like attending church.
The STEP trial randomized 1,802 heart bypass patients at six hospitals. Being prayed for by strangers made no difference to complications (52% versus 51%), and patients told for certain that they were being prayed for had more complications (59% versus 52%), with no difference in major events or death.
A survey of 1,300 teachers in Christian schools in four countries found that Sabbath keeping went with less burnout across several models. It was measured at one point in time, so it cannot say whether rest lowers burnout or whether less burned-out people find it easier to rest.
43 adults followed a 21-day Daniel Fast, eating plant foods drawn from the book of Daniel as much as they wanted. Total cholesterol fell from 171 to 139 mg/dL, LDL from 98 to 76 and systolic blood pressure from 115 to 106, but HDL fell too, calories dropped by about 460 a day, and there was no control group.
In 596 hospitalized adults over 55, higher scores for religious struggle predicted a higher death rate over two years, even after adjusting for health. The items that carried it were feeling abandoned by God, questioning God's love and believing the devil caused the illness.
