Every Skill You Are Paid For Is a Function of a Rested Brain

On The Lifestyle Investor, Dr. Meeta Singh talked with a host who had hired her as a patient. Ask a founder what they lose when they sleep badly and most will say stamina. Her answer is more specific and more expensive: judgment, creativity, memory, emotional regulation and the ability to read a room.

The Lifestyle Investor podcast, August 2023.

Every one of those is a function of a well-rested brain, and every one of them is what an executive is actually being paid for.

What the tired brain gives up first

Memory consolidation happens during sleep. Whatever you learned today is filed tonight, or it is not. Creativity and innovative thinking are functions of being rested. So is judgment, which Dr. Singh describes in terms any operator recognizes: being able to look at two proposals, weigh risk against benefit, and decide that A is better than B even when B looks better on the surface. That comparison is exactly the work that degrades first.

Then there is the category people dismiss as soft skills. Emotional intelligence. Self-awareness. How you talk to your team, your spouse, your children. Those are not personality traits that survive a bad month. They are outputs of a rested brain, and they are the first thing colleagues notice going missing.

Building and growing a business is stressful on its own terms. Being rested is what allows a person to cope with that stress rather than absorb it.

The entrepreneur's specific problem

Dr. Singh speaks about this partly from experience. Leaving a salaried physician role to build her own practice introduced a category of worry she had not had before, and it changed her relationships, because when you are building something the work becomes the life. Managing her own sleep during that period became directly important, because she could tell when she was making good decisions and when she was not, including in how she spoke to the people she worked with.

She is also realistic about the clients she works with. Many will not build in downtime. A general manager of a Major League Baseball team is not going to turn his phone off overnight, because if a player is in an accident or in trouble, that call comes to him. Telling him to switch off is not advice, it is a way of ending the conversation.

The useful work is different: figure out what can be delegated, build a team that can absorb the overnight call, and keep the person in charge without keeping them permanently on call. Balance is not the absence of responsibility. It is a structure that makes the responsibility survivable.

Sleep is a behavior, which is why advice alone fails

Dr. Singh is a psychiatrist as well as a sleep specialist, and her framing follows from that: sleep is a behavior. Everything you do during the day affects how you sleep at night, and how you sleep at night affects everything the next day. The relationship runs both ways, which is why treating sleep in isolation rarely works.

It also explains why knowing the answer changes so little. Almost everyone knows they should sleep well, eat well and exercise. The difficulty was never the information. It is not what you have to do, it is how you do it, and doing it consistently.

What worked with this particular client was accountability and visibility rather than instruction. A sleep diary gave him a sense of control and let him see his own pattern, so that when a change was suggested he could see why it made sense rather than being told. Her description of the working relationship is partnership rather than prescription: collect information in real time, make changes together, and sometimes decide to stop obsessing over a metric, because the obsession itself becomes the problem.

Her framing for anyone starting: treat these as tools on a journey rather than rules. Improvement in health comes from small continuous steps, and getting off track simply means getting back on.

Why the number is not eight

Adults generally need between seven and nine hours, and the variation between individuals is real. One person needs 8.2, another 7.9. Figuring out your own number matters more than adopting someone else's.

Dr. Singh's framing on timing is blunt in a useful way. If you are solving across resources, time and health, every day is a good day to work on health, because otherwise you run out of time.

She also accepts constraints rather than fighting them. When she tells a client that the season starts in a month and she understands they will not get enough sleep, the work becomes fitting as much sleep as possible into the schedule that exists, so they wake rested more often than not.

What sleep is doing while you are not using it

Because you are physically inactive during sleep, rest and recovery happen. Every organ and physiological system recovers and prepares for the next day. Immune function depends on it. So does metabolic control of glucose, which governs how the body takes in nutrition and uses it. Insufficient sleep is a risk factor for obesity. At the molecular level, DNA repair happens during sleep, which is part of why it is linked to longevity.

There is also a long-recognized, two-way relationship between sleep and mental health. Sleeping poorly increases the likelihood of developing depression, anxiety and substance problems. And when people have depression or anxiety, disturbed sleep becomes part of it. Treating the sleep is part of moving forward, which is a reason to pay attention rather than a reason to avoid the subject.

What it comes back to

Dr. Singh's view of a long, healthy life is unglamorous on purpose. Eat well, sleep enough and regularly, exercise, and maintain meaningful relationships and meaningful work. The longest-running research on happiness points at connections and relationships as the largest factor, the sense that you belong somewhere and that someone has your back.

And those are not separate from sleep. Poorly rested people regulate their emotions badly, manage relationships badly, and tend to withdraw. The Venn diagram keeps coming back to the same circle.

The honest limit

This is a conversation, not medical advice, and nothing here is a treatment plan for any individual. Persistent difficulty sleeping, or daytime impairment despite adequate time in bed, deserves evaluation rather than a routine change.
