Two stories today: Faye D'Souza argues that India's answer to sexual violence keeps taking freedom away from women, and Rhonda Patrick looks at two new papers on how far heat can stand in for exercise.
Faye D'Souza
After a 17-year-old was raped in a Delhi park on her birthday, the nearby women's college LSR moved classes online and the Delhi Development Authority limited entry to parks after sunset. Faye's point is that the response to violence against girls is to keep girls home. She adds new cases: in Uttar Pradesh, two police officers and two CRPF personnel are accused of raping a woman at a farmhouse (they're now arrested), and in Samastipur, Bihar, men surrounded and harassed a girl who was out with a boy. The root, she says, is a society that measures a girl by her virginity and marriageability, so men feel entitled to punish girls who step outside those rules. Wealthier women buy their way out with cars, drivers and pricier neighborhoods. She cites a 2019 urban mobility study: on the day surveyed, 53% of urban women hadn't left home, against 14% of men. Her fixes: give women their public spaces back at all hours (reliable buses, lit streets, kept-up parks), put women in charge of fixing them street by street and measure how many women can move freely, teach consent and equality from childhood starting with the men in power, and intervene every time harassment happens. Women are asking for safety, which the Constitution guarantees, not for protection that men hand out only to 'good girls'. Note: this summary is built from auto-generated captions.
Why it mattersIt moves this week's run of assault stories from the incidents to the policy response, and makes concrete, measurable asks.

Rhonda Patrick calls sauna and hot baths 'exercise mimetics': heat raises cardiovascular strain and blood-vessel shear stress the way aerobic exercise does. But sharing a signal isn't the same as matching the adaptation. Paper 1, a 12-week randomized trial in 31 inactive adults (average age 58, BMI 30), compared cycling 3x a week, immersion in 40°C water to the chest 3x a week for 30-40 minutes, and a control group. Arm-artery flow-mediated dilation rose 1% with cycling and 0.5% with hot water; the two weren't statistically different, but only exercise clearly beat control. Leg-artery FMD rose 1.5% with exercise, 0.5% with heat (not significant), and fell 0.4% in controls. Neither changed blood pressure or arterial stiffness. Paper 2, a meta-analysis co-authored by Brad Schoenfeld (6 interventions, 125 young adults, 4-12 weeks), found heat within 15 minutes after lifting gave slightly more lean-mass gain but no strength gain. Her advice: don't count heat toward weekly exercise targets; use it after training or on rest days; count hot yoga as exercise plus heat, not as a sauna session; and if muscle growth is the goal, keep cold plunges 6-8 hours away from lifting, because cold right after training can blunt gains. Heat may be most useful for older adults or people who can't exercise much.
Why it mattersIt gives clear numbers on what a sauna or hot bath does and doesn't replace, and how to sequence heat, lifting and cold.
